1
00:00:01,200 --> 00:00:04,640
Speaker 1: Welcome to Stuff you Should Know from house stuff Works

2
00:00:04,680 --> 00:00:13,720
Speaker 1: dot com. Hey, and welcome to the podcast. I'm Josh Clark,

3
00:00:13,760 --> 00:00:17,040
Speaker 1: There's Charles W. Chuck Bryant, and there's Jerry Rowland. So

4
00:00:17,160 --> 00:00:21,720
Speaker 1: this is stuff you should Know. Scratching Indigenous Yeah, this

5
00:00:21,800 --> 00:00:28,800
Speaker 1: is one of many. You remember when we did Yawning. Um, well,

6
00:00:28,840 --> 00:00:31,480
Speaker 1: that's the only one I can think of where just

7
00:00:31,680 --> 00:00:35,199
Speaker 1: researching something makes you do the thing you're researching. This

8
00:00:35,360 --> 00:00:38,160
Speaker 1: definitely happened with this one. Yeah. Well we ran across

9
00:00:38,159 --> 00:00:41,800
Speaker 1: that and poison ivy and scabies for sure. Oh yeah,

10
00:00:41,840 --> 00:00:43,600
Speaker 1: and talked about some of this stuff. But I think

11
00:00:43,680 --> 00:00:47,400
Speaker 1: it we had an itch we needed to scratch with

12
00:00:47,479 --> 00:00:50,520
Speaker 1: this particular topic. Well, I'm glad, um, I've been wanting

13
00:00:50,520 --> 00:00:52,400
Speaker 1: to do this one for a while. Yeah, you did

14
00:00:52,440 --> 00:00:56,800
Speaker 1: a video about this, right, Yes, a short video. No,

15
00:00:56,960 --> 00:01:00,200
Speaker 1: it was three or four hours long. Okay, if I

16
00:01:00,280 --> 00:01:02,920
Speaker 1: remember correctly, that mean we have to do this. You

17
00:01:03,080 --> 00:01:04,560
Speaker 1: have to be here for the next four hours. Yeah,

18
00:01:04,640 --> 00:01:06,440
Speaker 1: we have to just play the whole thing and then

19
00:01:06,440 --> 00:01:09,360
Speaker 1: we'll talk about it for an hour after. Okay. I

20
00:01:09,360 --> 00:01:11,520
Speaker 1: think it was a brain stuff video, isn't it. I

21
00:01:11,560 --> 00:01:16,199
Speaker 1: watched Did it scratch your itch? Yeah, I watched it yesterday.

22
00:01:16,440 --> 00:01:18,959
Speaker 1: Nice work, thank you very much. Just like now we

23
00:01:19,040 --> 00:01:23,640
Speaker 1: finally arrive on what I was after compliment. Yeah, it

24
00:01:23,800 --> 00:01:27,720
Speaker 1: was great, thanks man. Um. So I guess the point

25
00:01:27,720 --> 00:01:30,160
Speaker 1: of all that is to say, you guys are going

26
00:01:30,400 --> 00:01:33,960
Speaker 1: you're going right, and my videos are the best. Uh,

27
00:01:34,160 --> 00:01:38,640
Speaker 1: that you're going to scratch, You're gonna feel an itch,

28
00:01:39,040 --> 00:01:41,600
Speaker 1: which is one of the great mysteries of itches. It

29
00:01:41,640 --> 00:01:44,880
Speaker 1: turns out we only very very recently have started to

30
00:01:44,920 --> 00:01:49,200
Speaker 1: get a handle on what itches are, um, and there's

31
00:01:49,200 --> 00:01:51,560
Speaker 1: still plenty of mysteries left to it. Like, for example,

32
00:01:51,960 --> 00:01:56,000
Speaker 1: it's bizarre and there's really no evolutionary reason as far

33
00:01:56,040 --> 00:01:59,280
Speaker 1: as anyone can tell, why just hearing about itches or

34
00:01:59,600 --> 00:02:04,480
Speaker 1: seeing someone else scratch can make you itch. Right, That's

35
00:02:04,680 --> 00:02:07,960
Speaker 1: that's odd, That's that's weird. The video of an ant

36
00:02:08,000 --> 00:02:10,960
Speaker 1: crawling up an arm will make you itch. It will.

37
00:02:11,160 --> 00:02:13,639
Speaker 1: But I mean, think about it. If somebody is sitting there, Um,

38
00:02:13,800 --> 00:02:17,080
Speaker 1: you see a video of some schmo who's got his

39
00:02:17,160 --> 00:02:19,480
Speaker 1: hand like near an oven, and he pulls it away

40
00:02:19,520 --> 00:02:22,440
Speaker 1: really quick. It doesn't hurt your hand, It doesn't make

41
00:02:22,480 --> 00:02:25,799
Speaker 1: you feel like your hand is burned. That doesn't happen.

42
00:02:25,880 --> 00:02:28,040
Speaker 1: I don't even think that would excite mirror neurons like

43
00:02:28,040 --> 00:02:31,160
Speaker 1: a leg break with You're just like, what a stupid idiot,

44
00:02:31,240 --> 00:02:34,119
Speaker 1: that's what it excites. Yeah, I hope that guy's hand

45
00:02:34,160 --> 00:02:38,680
Speaker 1: just burns clean off. That's what I think. Right. Uh,

46
00:02:38,880 --> 00:02:41,239
Speaker 1: you sourced a couple of well we've had our own

47
00:02:41,320 --> 00:02:44,160
Speaker 1: article on how stuff works dot com, but you also

48
00:02:44,200 --> 00:02:48,360
Speaker 1: sent this great New Yorker article, um, written by Dr

49
00:02:48,880 --> 00:02:51,799
Speaker 1: a tool go on Day, one of the best names

50
00:02:52,080 --> 00:02:56,880
Speaker 1: in writing today. Yeah, that may be my new hotel name. Well,

51
00:02:57,040 --> 00:03:01,000
Speaker 1: you may be thronged by science right, science fans, because

52
00:03:01,000 --> 00:03:03,480
Speaker 1: that guy's pretty pretty well known. Actually I don't. I've

53
00:03:03,520 --> 00:03:05,799
Speaker 1: never used to alias at a hotel. That's dumb. I

54
00:03:05,840 --> 00:03:07,320
Speaker 1: don't even know if you can. Can you? I guess

55
00:03:07,360 --> 00:03:09,840
Speaker 1: if you're a big shot you can. Yeah, but you

56
00:03:09,880 --> 00:03:12,880
Speaker 1: have to be like, I'm not Brad Pitt, I'm a

57
00:03:12,919 --> 00:03:17,040
Speaker 1: tool go on Day right. Uh. But the we'll get

58
00:03:17,080 --> 00:03:20,200
Speaker 1: to some of the uh more interesting aspects of that

59
00:03:20,320 --> 00:03:25,760
Speaker 1: article later, specifically a very specific patient that's quite distressing,

60
00:03:26,360 --> 00:03:29,760
Speaker 1: So calm down for now, a Tool's mom, but get

61
00:03:29,800 --> 00:03:32,320
Speaker 1: to it eventually. He did include a couple of neat

62
00:03:32,360 --> 00:03:37,840
Speaker 1: historical tidbits Uh, like in sixteen sixty there was in

63
00:03:37,880 --> 00:03:41,520
Speaker 1: Germans are all over this thing for some reason. Yeah,

64
00:03:41,640 --> 00:03:44,240
Speaker 1: you know researchers that they're they're all German. They had

65
00:03:44,320 --> 00:03:48,520
Speaker 1: the itch to explain the itch. I guess it right.

66
00:03:49,320 --> 00:03:53,320
Speaker 1: But there was a position in sixteen sixty named Samuel Hoffenruffer.

67
00:03:54,160 --> 00:03:56,760
Speaker 1: Actually that's my new hotel name. Yeah, that's a good one.

68
00:03:57,440 --> 00:04:00,320
Speaker 1: Uh he kind of well, he defined it by saying,

69
00:04:00,600 --> 00:04:05,920
Speaker 1: an itch is an unpleasant sensation that provokes the desire

70
00:04:06,040 --> 00:04:11,120
Speaker 1: to scratch. Pretty simple, but right on the money it is.

71
00:04:11,120 --> 00:04:13,640
Speaker 1: And actually it's so it's so on the money that

72
00:04:13,960 --> 00:04:17,360
Speaker 1: anywhere you look in the medical literature, whenever they define

73
00:04:17,400 --> 00:04:21,799
Speaker 1: itch word for word, that's the definition they use. Yeah,

74
00:04:21,920 --> 00:04:24,240
Speaker 1: although poor hoff and reference doesn't get credit for it

75
00:04:24,279 --> 00:04:26,880
Speaker 1: all the time, but that's the one. The only expansion

76
00:04:26,920 --> 00:04:30,120
Speaker 1: of that that I've seen is that can occur anywhere

77
00:04:30,120 --> 00:04:33,000
Speaker 1: on the body, which apparently is true. I think haf

78
00:04:33,240 --> 00:04:37,240
Speaker 1: reference he felt that was implied. And it's like it

79
00:04:37,320 --> 00:04:41,520
Speaker 1: goes without saying, yeah, and then I'm scratching right now,

80
00:04:41,640 --> 00:04:44,760
Speaker 1: you know, Yeah, it's started. I don't know if I

81
00:04:44,839 --> 00:04:47,880
Speaker 1: just noticed more, because as I was doing it, I

82
00:04:47,920 --> 00:04:50,760
Speaker 1: was thinking, well, now, I'm scratching, but I thought, do

83
00:04:50,800 --> 00:04:53,320
Speaker 1: I always scratch this much? Or it's this much? Oh,

84
00:04:53,360 --> 00:04:55,880
Speaker 1: I hadn't thought about that. I'm pretty sure that I was.

85
00:04:56,200 --> 00:04:59,040
Speaker 1: I don't think I scratched as much as I don't know.

86
00:04:59,400 --> 00:05:01,920
Speaker 1: Do you raise a really good question. Maybe we can

87
00:05:01,960 --> 00:05:05,240
Speaker 1: get an intern to follow us around and just record

88
00:05:05,240 --> 00:05:08,719
Speaker 1: our scratching. Right, I'm surprised that that's not already a

89
00:05:08,760 --> 00:05:15,600
Speaker 1: TV show. Frankly, Josh and Chuck scratch just being followed around. Yeah, oh,

90
00:05:15,680 --> 00:05:18,400
Speaker 1: you know, no one wants to see that. Well, that's

91
00:05:18,400 --> 00:05:21,279
Speaker 1: probably why it's not you're scratching. See, that's what I'm saying.

92
00:05:21,279 --> 00:05:24,760
Speaker 1: I don't think I scratched this much. I don't notice

93
00:05:24,760 --> 00:05:32,080
Speaker 1: it alright. Moving on, um to Dante's Inferno. Uh, it

94
00:05:32,160 --> 00:05:35,320
Speaker 1: was in Dante's Inferno, the burning rage of fierce itching

95
00:05:35,520 --> 00:05:39,120
Speaker 1: that nothing could relieve is how falsifiers were punished. Yeah.

96
00:05:39,160 --> 00:05:45,719
Speaker 1: Do you know what a falsifiers us? I know really like.

97
00:05:45,839 --> 00:05:49,200
Speaker 1: Isn't that that somebody who like bears false witness, or

98
00:05:49,279 --> 00:05:52,440
Speaker 1: somebody who falsifies a document or is it just a

99
00:05:52,480 --> 00:05:55,359
Speaker 1: fancy name for liar? Maybe? Oh, I thought you were

100
00:05:55,360 --> 00:05:57,560
Speaker 1: gonna tell me you were just wondering. Yeah, I don't.

101
00:05:57,600 --> 00:06:00,000
Speaker 1: I don't know, all right, I don't know what don

102
00:06:00,040 --> 00:06:03,560
Speaker 1: they meant, but they're they're bad people. Apparently there's a

103
00:06:03,600 --> 00:06:06,480
Speaker 1: special place in health for him literally, well, I guess

104
00:06:06,480 --> 00:06:13,839
Speaker 1: actually not literally figuratively literarily, Oh very nice. Uh So,

105
00:06:13,960 --> 00:06:18,600
Speaker 1: itching um scientifically is known as uh puritis p r

106
00:06:18,720 --> 00:06:21,239
Speaker 1: U r I t I s. It's one of those

107
00:06:21,760 --> 00:06:25,599
Speaker 1: tough to pronounce things for me at least um and

108
00:06:25,800 --> 00:06:29,039
Speaker 1: for well. Actually, they still believe that the evolution of

109
00:06:29,080 --> 00:06:34,200
Speaker 1: the itch was to help humans um survive basically because

110
00:06:34,600 --> 00:06:37,760
Speaker 1: so many things that can kill you, uh, and and

111
00:06:38,040 --> 00:06:43,359
Speaker 1: nature or things like mosquitoes or flies or spiders or

112
00:06:43,400 --> 00:06:46,760
Speaker 1: fleas that can have like malaria or the plague or

113
00:06:46,800 --> 00:06:53,120
Speaker 1: any number of diseases attached to their tiny little insect bodies. So, hey, human, um,

114
00:06:53,120 --> 00:06:54,880
Speaker 1: you've got a mosquito on your neck that could kill

115
00:06:54,920 --> 00:06:58,960
Speaker 1: you. You You might want to slap it or scratch. Yeah,

116
00:06:59,080 --> 00:07:01,520
Speaker 1: And that's still, as far as I know, the the

117
00:07:01,880 --> 00:07:06,800
Speaker 1: evolutionary hypothesis for why we experience itching. Yeah, and it's

118
00:07:06,800 --> 00:07:09,880
Speaker 1: not just us either. What you're scratching like crazy, it's

119
00:07:09,920 --> 00:07:15,000
Speaker 1: found throughout the animal kingdom um from us too, apparently,

120
00:07:15,040 --> 00:07:18,800
Speaker 1: fish have shown scratching behavior. Yeah, that's crazy fruit flies.

121
00:07:18,960 --> 00:07:21,200
Speaker 1: How's the fish scratch? You might ask? It rubs up

122
00:07:21,240 --> 00:07:24,520
Speaker 1: against rocks. It's kind of cute. It is a little cute.

123
00:07:24,560 --> 00:07:27,480
Speaker 1: It's like I remember my dad did like the uh

124
00:07:28,720 --> 00:07:31,480
Speaker 1: who was the Barren Jungle book? Was that blue? Yes?

125
00:07:31,680 --> 00:07:33,240
Speaker 1: He would do the blue or he would get up

126
00:07:33,240 --> 00:07:36,120
Speaker 1: against a tree or a wall. And then I did

127
00:07:36,160 --> 00:07:39,120
Speaker 1: it probably because of that. I'm sure that's where I

128
00:07:39,120 --> 00:07:41,800
Speaker 1: got it and realized that it works. And I still

129
00:07:41,840 --> 00:07:43,600
Speaker 1: do it every now and then. Oh yeah, yeah, it

130
00:07:43,600 --> 00:07:47,200
Speaker 1: look kind of silly. But do you sing while you do? Yeah?

131
00:07:47,520 --> 00:07:50,200
Speaker 1: Bair necessities, that's still my favorite. What else are you

132
00:07:50,200 --> 00:07:57,000
Speaker 1: gonna sing? Like Mambo number five? I'm gonna start doing that.

133
00:07:57,040 --> 00:08:00,920
Speaker 1: Actually you could be like, think something's wrong with yeah. So,

134
00:08:01,000 --> 00:08:06,480
Speaker 1: like you said, though, it was up until almost was seven,

135
00:08:06,520 --> 00:08:10,280
Speaker 1: the mid to late eighties that another German h O

136
00:08:10,480 --> 00:08:19,720
Speaker 1: hand worker UH and his gang um they started to

137
00:08:19,840 --> 00:08:23,000
Speaker 1: do actual like research about it. They were puzzled and

138
00:08:23,000 --> 00:08:25,880
Speaker 1: wanted to solve it right because up to this point,

139
00:08:26,040 --> 00:08:30,840
Speaker 1: up to actually seven, everyone thought that an itch was

140
00:08:30,960 --> 00:08:36,240
Speaker 1: just a low grade pain stimulus. Since they're happy with that,

141
00:08:36,240 --> 00:08:39,280
Speaker 1: that's just what they thought it was. And hand worker said,

142
00:08:39,360 --> 00:08:41,360
Speaker 1: you know what, let's let's find out if this is

143
00:08:41,360 --> 00:08:44,600
Speaker 1: actually true. I'm tired of sitting around just assuming this

144
00:08:44,679 --> 00:08:47,959
Speaker 1: is fine. I'm a hand worker. And he got to

145
00:08:48,080 --> 00:08:52,880
Speaker 1: work or at his hands testing this. Right. So what

146
00:08:52,960 --> 00:08:57,559
Speaker 1: he I know is like Jonathan Strickland level funds um.

147
00:08:57,679 --> 00:09:03,319
Speaker 1: What he did was this is just awful. He introduced

148
00:09:03,400 --> 00:09:07,479
Speaker 1: using like um electrical stimulation. I guess he introduced histamine

149
00:09:07,480 --> 00:09:11,480
Speaker 1: to skin cells. Right. And histamine is a natural I

150
00:09:11,520 --> 00:09:13,520
Speaker 1: don't know if it's a protein, but it's it's a natural,

151
00:09:14,000 --> 00:09:18,680
Speaker 1: natural chemical, right that the body releases UH in response

152
00:09:18,760 --> 00:09:22,080
Speaker 1: to certain stimuli, say, for example, like a mosquito bite

153
00:09:22,160 --> 00:09:26,640
Speaker 1: or something, and it triggers the inflammation and immune response

154
00:09:26,960 --> 00:09:31,840
Speaker 1: in that area. Right. So histamine is associated with itch,

155
00:09:31,880 --> 00:09:33,840
Speaker 1: and it had been for a very long time. So

156
00:09:33,880 --> 00:09:40,040
Speaker 1: this guy was using electrical stimulation to introduce histamine in

157
00:09:40,040 --> 00:09:44,199
Speaker 1: increasing amounts in these poor study participants, and it went

158
00:09:44,280 --> 00:09:48,920
Speaker 1: from barely noticeable to this is a quote the maximum

159
00:09:48,960 --> 00:09:54,800
Speaker 1: imaginable itch. And they never felt pain. Yeah, Like, even

160
00:09:54,800 --> 00:09:57,120
Speaker 1: though they ramped it up to eleven, no one ever

161
00:09:57,160 --> 00:10:00,240
Speaker 1: said like, holy crap, that hurts. But they said, please, please,

162
00:10:00,240 --> 00:10:02,160
Speaker 1: for love, God, stop let me out of this. And

163
00:10:02,280 --> 00:10:06,720
Speaker 1: hand worker just cackled and cackled. Right, these men with

164
00:10:06,760 --> 00:10:10,320
Speaker 1: like black leather gloves are holding the participants down. Yeah,

165
00:10:10,360 --> 00:10:13,079
Speaker 1: they said, this is not worth the five deutsch marks

166
00:10:13,480 --> 00:10:16,320
Speaker 1: that I'm getting for the slousy study. Yeah, that's nice man,

167
00:10:16,360 --> 00:10:20,120
Speaker 1: that's This would have been pre euro I think even

168
00:10:20,160 --> 00:10:22,040
Speaker 1: though the EU was around, I don't think the euro

169
00:10:22,120 --> 00:10:24,000
Speaker 1: was around in eighties seven, right, No, no, because in

170
00:10:24,200 --> 00:10:31,880
Speaker 1: nineties I traveled, Uh, I traveled to Europe in and

171
00:10:31,920 --> 00:10:36,960
Speaker 1: that was I was still on all the weird money. Okay, yeah,

172
00:10:37,000 --> 00:10:41,760
Speaker 1: so it was a while after that. So now scientists, uh,

173
00:10:41,960 --> 00:10:46,760
Speaker 1: I think this sort of um introduced an itch to

174
00:10:46,840 --> 00:10:51,280
Speaker 1: the scientific community because after hundreds and hundreds of years,

175
00:10:51,760 --> 00:10:55,880
Speaker 1: hand Vuka sort of disrupted the thought process of the

176
00:10:55,960 --> 00:10:58,920
Speaker 1: itch and the scratch, and all of a sudden, scientists

177
00:10:58,920 --> 00:11:01,000
Speaker 1: were like, oh, well, maybe should start looking into this.

178
00:11:01,080 --> 00:11:04,320
Speaker 1: Maybe we can actually isolate the nerve and figure this

179
00:11:04,360 --> 00:11:06,760
Speaker 1: thing out. Yeah, because I mean, if it's not if

180
00:11:06,800 --> 00:11:12,440
Speaker 1: it's not just low level pain sensation, then that means

181
00:11:12,440 --> 00:11:14,240
Speaker 1: it's its own thing. And if it's its own thing,

182
00:11:14,280 --> 00:11:16,360
Speaker 1: it probably has its own system and we need to

183
00:11:16,360 --> 00:11:18,160
Speaker 1: know more about it. So they got to they got

184
00:11:18,200 --> 00:11:20,319
Speaker 1: to study in it. Yeah. What makes I wonder if

185
00:11:20,360 --> 00:11:23,040
Speaker 1: all of this was under the notion that they were

186
00:11:23,080 --> 00:11:28,200
Speaker 1: trying to cure it. I don't know, because from what

187
00:11:28,320 --> 00:11:31,080
Speaker 1: I was reading, UM, and all of this was pretty

188
00:11:31,160 --> 00:11:36,040
Speaker 1: recent stuff. There's a real un medical need in dealing

189
00:11:36,280 --> 00:11:40,280
Speaker 1: and addressing like chronic itch because you know, most people

190
00:11:40,320 --> 00:11:43,920
Speaker 1: who go through life just experiencing it's under normal circumstances,

191
00:11:44,000 --> 00:11:46,640
Speaker 1: right like, say you or me, we're like an itch. Yeah,

192
00:11:46,679 --> 00:11:48,880
Speaker 1: they suck for a second and then it goes away.

193
00:11:49,200 --> 00:11:52,760
Speaker 1: Imagine it not going away ever, whether you're asleep or awake,

194
00:11:53,080 --> 00:11:57,520
Speaker 1: or um swimming or an outer space or doom, whatever,

195
00:11:58,120 --> 00:12:02,760
Speaker 1: you're itching constantly. Suppose really, um, it has as much

196
00:12:02,800 --> 00:12:06,120
Speaker 1: of a pronounced effect on a patient's life UM as

197
00:12:06,200 --> 00:12:11,560
Speaker 1: chronic pain does. It's constant, persistent, and agonizing, and it's

198
00:12:11,600 --> 00:12:15,480
Speaker 1: not it's not being met or treated because it's not understood.

199
00:12:15,840 --> 00:12:18,800
Speaker 1: So they're just now starting to get into pain re

200
00:12:19,120 --> 00:12:22,920
Speaker 1: or itch research. I saw UM that somebody put it

201
00:12:22,960 --> 00:12:25,920
Speaker 1: where pain research was about twenty years ago. So it's

202
00:12:25,920 --> 00:12:28,480
Speaker 1: starting to really heat up, but we're still just starting

203
00:12:28,480 --> 00:12:31,079
Speaker 1: to understand it. So I would think that they weren't

204
00:12:31,120 --> 00:12:33,320
Speaker 1: looking to cure it. I think it was just pointed

205
00:12:33,360 --> 00:12:35,760
Speaker 1: out that there was this whole branch of neuroscience that

206
00:12:35,880 --> 00:12:41,040
Speaker 1: was totally not understood. So get to work neurologists. I

207
00:12:41,080 --> 00:12:43,520
Speaker 1: wonder I never really thought about until just now, but

208
00:12:43,559 --> 00:12:48,679
Speaker 1: I wonder what happens when a a performer or somebody

209
00:12:48,720 --> 00:12:50,960
Speaker 1: like that is in the public eye or on TV

210
00:12:51,240 --> 00:12:56,880
Speaker 1: or on stage, or like the president giving a address,

211
00:12:56,960 --> 00:12:59,320
Speaker 1: Like what what what do they do if they have poison,

212
00:12:59,400 --> 00:13:03,000
Speaker 1: ivy or some other kind of contact dermatitis? Have you

213
00:13:03,000 --> 00:13:05,880
Speaker 1: ever thought about that? Like what if Lynn mal went

214
00:13:05,920 --> 00:13:08,840
Speaker 1: Manuel Miranda has like a really bad case of pin.

215
00:13:08,960 --> 00:13:10,720
Speaker 1: I guess they can get an understudy in that case,

216
00:13:11,320 --> 00:13:15,120
Speaker 1: But you can't have an understudy as president, which is

217
00:13:15,120 --> 00:13:17,240
Speaker 1: too bad. You just go out there with your hands

218
00:13:17,240 --> 00:13:19,600
Speaker 1: bandaged up, just holding them up, Like how do you

219
00:13:19,640 --> 00:13:22,640
Speaker 1: fight that on camera? Or like a news anchor when

220
00:13:22,679 --> 00:13:27,040
Speaker 1: they're just like, oh my god, I'm dying. I don't know.

221
00:13:27,800 --> 00:13:29,480
Speaker 1: I guess the news anchor can tape things, but I'm

222
00:13:29,480 --> 00:13:33,120
Speaker 1: talking about live. What's Tom Petty do? For God's sakes,

223
00:13:33,360 --> 00:13:35,880
Speaker 1: Tom Petty grins and bears it. He had a hard

224
00:13:35,880 --> 00:13:39,680
Speaker 1: scrabble childhood prepared him for that. I'm going to see

225
00:13:39,760 --> 00:13:47,559
Speaker 1: him tomorrow night, Yeah, for coffee. He's not performing. Um anyway,

226
00:13:47,640 --> 00:13:49,600
Speaker 1: I was just curious about that. Um. Well, it's a

227
00:13:49,640 --> 00:13:52,840
Speaker 1: good question. Thanks. Do you remember when Kosta's head red

228
00:13:52,880 --> 00:13:56,360
Speaker 1: eye at the Olympics and it was so dedicated to

229
00:13:56,000 --> 00:13:58,800
Speaker 1: to being the commentator the anchor for the Olympics. They

230
00:13:58,800 --> 00:14:02,480
Speaker 1: finally were like, you have to stop keep writing in

231
00:14:03,080 --> 00:14:06,600
Speaker 1: you're disgusting them. Uh. One thing that made me think

232
00:14:06,600 --> 00:14:09,240
Speaker 1: of that is I had UM recently. You can still

233
00:14:09,280 --> 00:14:11,280
Speaker 1: kind of see it on my forearm that the scars.

234
00:14:11,880 --> 00:14:15,560
Speaker 1: But I did a cement job. Was building this fence,

235
00:14:16,200 --> 00:14:20,560
Speaker 1: putting in a gate at my house, and um, Scotty,

236
00:14:20,640 --> 00:14:25,400
Speaker 1: you know, Scotty and I built Scotti tipping uh. He

237
00:14:25,480 --> 00:14:29,920
Speaker 1: and I built this uh thing together and we sank

238
00:14:29,960 --> 00:14:33,880
Speaker 1: these huge posts for this gate. And I didn't know

239
00:14:33,960 --> 00:14:38,240
Speaker 1: that cement uh could cause contact dermatitis or even burns.

240
00:14:38,760 --> 00:14:42,560
Speaker 1: Never knew this, And we were it was kind of

241
00:14:42,560 --> 00:14:44,760
Speaker 1: a tight spot and we couldn't get shovels in there

242
00:14:44,760 --> 00:14:46,600
Speaker 1: in the hole, so we were literally mixing the stuff

243
00:14:46,600 --> 00:14:48,880
Speaker 1: like up to our elbows with our arms, and I

244
00:14:48,920 --> 00:14:51,160
Speaker 1: was like, this kind of feels good. I even said, like,

245
00:14:51,240 --> 00:14:53,800
Speaker 1: you know, like oatmeal or something. And then two days

246
00:14:53,880 --> 00:14:57,560
Speaker 1: later my right arm was just covered in the nastiest

247
00:14:57,800 --> 00:15:01,200
Speaker 1: dermatitis I've ever seen, and then he got it. Yeah,

248
00:15:01,200 --> 00:15:03,440
Speaker 1: it's still like kind of hanging around. So I went

249
00:15:03,480 --> 00:15:07,880
Speaker 1: and got a prescription for steroids, which made me a

250
00:15:07,920 --> 00:15:11,960
Speaker 1: little crazy for a week and a half. Um, trash

251
00:15:12,040 --> 00:15:15,280
Speaker 1: the gate and have to start over. I think I

252
00:15:15,320 --> 00:15:19,360
Speaker 1: was probably not the best husband though over that time period. UM,

253
00:15:19,440 --> 00:15:23,280
Speaker 1: judging from Emily saying, hey, you're real a hole, Get

254
00:15:23,280 --> 00:15:27,480
Speaker 1: off the steroids, Um, get off the juice, I was like,

255
00:15:27,680 --> 00:15:31,440
Speaker 1: shut up, watch this, watch me hit this Homer. So

256
00:15:31,800 --> 00:15:35,120
Speaker 1: long story short, I experienced this recently and it was awful.

257
00:15:35,160 --> 00:15:37,720
Speaker 1: And I can't imagine like shooting the TV show or something,

258
00:15:38,560 --> 00:15:41,680
Speaker 1: or like doing anything on or performing live like I

259
00:15:41,680 --> 00:15:45,160
Speaker 1: would have to address it because I would scratch and smack.

260
00:15:45,240 --> 00:15:48,160
Speaker 1: It was what I usually do. That's how you're supposed

261
00:15:48,160 --> 00:15:50,800
Speaker 1: to do, not scratch. Well, I guess we'll just cut

262
00:15:50,800 --> 00:15:53,000
Speaker 1: to the chase hairs. Is why everyone's listening. How do

263
00:15:53,040 --> 00:15:57,600
Speaker 1: you scratch a niche? Correctly? You rub it? Yeah I

264
00:15:57,600 --> 00:15:59,520
Speaker 1: didn't do I did you know? What really did? It

265
00:15:59,600 --> 00:16:04,880
Speaker 1: was the uh we have a handheld implement in the

266
00:16:04,920 --> 00:16:08,160
Speaker 1: shower along with the regular shower head and put that

267
00:16:08,200 --> 00:16:14,000
Speaker 1: sucker on the tightest, hardest, most penetrating flow and just

268
00:16:14,280 --> 00:16:16,400
Speaker 1: put that hot water on it. Man, And that was like,

269
00:16:17,160 --> 00:16:19,280
Speaker 1: I think I spent half my days in the shower

270
00:16:19,680 --> 00:16:21,520
Speaker 1: over that week and a half. Are you biting down

271
00:16:21,600 --> 00:16:23,640
Speaker 1: like a broomstick while you're doing that? How it felt

272
00:16:23,680 --> 00:16:25,480
Speaker 1: so good? Man? I was just like I couldn't get

273
00:16:25,560 --> 00:16:28,040
Speaker 1: enough of it. Huh. And then the court of zone

274
00:16:28,320 --> 00:16:33,080
Speaker 1: and all that jump too. So we'll well, we'll talk

275
00:16:33,120 --> 00:16:35,640
Speaker 1: about this because this is you're raising some great points here.

276
00:16:35,800 --> 00:16:39,440
Speaker 1: Well I just kind of that are ruined the spoiler. No, no,

277
00:16:39,480 --> 00:16:41,800
Speaker 1: this is good stuff. We're gonna analyze what was going

278
00:16:41,840 --> 00:16:44,040
Speaker 1: on with your arm after this break? How about that

279
00:16:44,520 --> 00:17:08,359
Speaker 1: sounds good? So, Chuck, you had contact dermatitis, right, I

280
00:17:08,359 --> 00:17:10,320
Speaker 1: thought it was poison ivy because that area has some

281
00:17:10,359 --> 00:17:14,080
Speaker 1: poison ivy. But each of us, Scotty and I had

282
00:17:14,119 --> 00:17:17,560
Speaker 1: it just on the arm that we sunk in sument.

283
00:17:18,600 --> 00:17:20,879
Speaker 1: And then we researched and found out that could happen. Yeah,

284
00:17:20,960 --> 00:17:24,600
Speaker 1: so lesson learned on that. Yeah. So what happened was

285
00:17:25,080 --> 00:17:27,800
Speaker 1: you like something in the cement and I'm not sure

286
00:17:27,840 --> 00:17:33,040
Speaker 1: what it was reacting chemically with the um mast cells

287
00:17:33,119 --> 00:17:38,040
Speaker 1: in your skin, and histamine was released, right apparently, And

288
00:17:38,119 --> 00:17:44,640
Speaker 1: so the histamine UM sent a signal through specialized nerve

289
00:17:44,720 --> 00:17:48,840
Speaker 1: cells called sea fibers. Yeah, which UM. Sea fibers aren't

290
00:17:48,920 --> 00:17:51,840
Speaker 1: just limited to itching. I think only about five handle

291
00:17:51,920 --> 00:17:54,159
Speaker 1: that and most of the rest are for pain. Right,

292
00:17:54,600 --> 00:17:59,359
Speaker 1: So they used the same type of neural pathway as

293
00:17:59,440 --> 00:18:02,760
Speaker 1: pain for itch. It's it's basically it's just like, no,

294
00:18:02,920 --> 00:18:06,080
Speaker 1: these these are just for itches only. And it sent

295
00:18:06,280 --> 00:18:10,000
Speaker 1: a signal through your spinal column, and in your spinal

296
00:18:10,040 --> 00:18:16,560
Speaker 1: column it released a neurotransmitter called UM gastron releasing peptide receptor,

297
00:18:16,800 --> 00:18:19,400
Speaker 1: and so at the skin, the histamine would have released

298
00:18:19,400 --> 00:18:26,320
Speaker 1: a neurotransmitter called what natural uretic polypeptide B Okay, So

299
00:18:26,440 --> 00:18:29,560
Speaker 1: that says it's signal coming your way along those sea

300
00:18:29,640 --> 00:18:32,960
Speaker 1: fibers okay. Uh, it makes it to the spinal column,

301
00:18:33,000 --> 00:18:34,760
Speaker 1: and I guess in about two thousand and seven they

302
00:18:34,800 --> 00:18:38,919
Speaker 1: found that there's another neurotransmitter in the spine that I

303
00:18:38,960 --> 00:18:43,959
Speaker 1: guess UM accepts the the n p PB the invitation

304
00:18:44,280 --> 00:18:46,760
Speaker 1: and says I'm going to transfer this along up to

305
00:18:46,760 --> 00:18:50,560
Speaker 1: the brain. That's gastron releasing peptide receptor that shoots up

306
00:18:50,560 --> 00:18:54,080
Speaker 1: to the brain and it starts this cascade of activity.

307
00:18:54,240 --> 00:18:57,960
Speaker 1: Right because when they, like after hand worker said, hey,

308
00:18:58,000 --> 00:19:00,800
Speaker 1: you know, itching is its own thing. The other researchers

309
00:19:00,840 --> 00:19:04,280
Speaker 1: went to town and traced and figured out there that

310
00:19:04,359 --> 00:19:10,000
Speaker 1: there were specific um specific types of its receptors that

311
00:19:10,040 --> 00:19:13,600
Speaker 1: were dedicated just two itches, right, more Germans, more Germans,

312
00:19:14,200 --> 00:19:17,720
Speaker 1: a couple of Swedes, but mostly Germans for good measures. Yeah,

313
00:19:17,800 --> 00:19:20,600
Speaker 1: And what they found eventually from tracing this pathway, they

314
00:19:20,600 --> 00:19:23,840
Speaker 1: were able to follow it into the Wonder machine and

315
00:19:23,880 --> 00:19:26,800
Speaker 1: apparently they made some people itch and would not let

316
00:19:26,840 --> 00:19:29,120
Speaker 1: them scratch it. And then they had them lay down

317
00:19:29,160 --> 00:19:31,560
Speaker 1: in an m r I and they took a brain

318
00:19:31,600 --> 00:19:35,679
Speaker 1: skin and they found that there's this whole galaxy of

319
00:19:35,760 --> 00:19:39,639
Speaker 1: stuff going on in your brain that combined is the

320
00:19:39,760 --> 00:19:42,720
Speaker 1: itch sensation. Yeah, it was pretty interesting too. There's a

321
00:19:42,800 --> 00:19:45,840
Speaker 1: there's a signature pattern in the brain when you get

322
00:19:45,880 --> 00:19:49,680
Speaker 1: an itch, and uh, a few specific areas light up.

323
00:19:49,960 --> 00:19:52,320
Speaker 1: One is a cortex and it all makes sense when

324
00:19:52,359 --> 00:19:56,480
Speaker 1: you put it together. The cortex, uh, in this case

325
00:19:57,359 --> 00:20:00,280
Speaker 1: just sort of geo locates where on your body. You're

326
00:20:00,320 --> 00:20:05,640
Speaker 1: getting that sensation, so that helps. It's like left elbow, yeah,

327
00:20:05,760 --> 00:20:08,840
Speaker 1: or in my case from right elbow to wrist, right,

328
00:20:09,720 --> 00:20:12,119
Speaker 1: and then a little bit in other places, but not

329
00:20:12,160 --> 00:20:14,399
Speaker 1: too bad. That that was the main area. Is this

330
00:20:14,440 --> 00:20:21,400
Speaker 1: your cortex still saying this, Yeah, very complex conversation going on. Uh.

331
00:20:21,440 --> 00:20:23,439
Speaker 1: And then the region I thought this is interesting, the

332
00:20:23,480 --> 00:20:28,800
Speaker 1: region that governments governments that governs emotional response. Um, so

333
00:20:28,840 --> 00:20:31,520
Speaker 1: basically this is your brain saying like, I don't like this,

334
00:20:31,520 --> 00:20:33,840
Speaker 1: this makes me feel bad. It's the worst thing ever

335
00:20:33,920 --> 00:20:36,760
Speaker 1: do something. And then finally the olymbic and motor areas,

336
00:20:37,080 --> 00:20:40,120
Speaker 1: and I thought this was the most interesting. Um, those

337
00:20:40,160 --> 00:20:44,520
Speaker 1: areas process irresistible urges, the same ones that say I

338
00:20:44,560 --> 00:20:47,320
Speaker 1: want to smoke crack or I wanna eat too much cake,

339
00:20:48,400 --> 00:20:51,240
Speaker 1: says you have an itch that is unbearable and you

340
00:20:51,280 --> 00:20:53,960
Speaker 1: need to scratch it and maybe go smoke some crack

341
00:20:54,000 --> 00:20:55,639
Speaker 1: and eat some cake while you're at it because that

342
00:20:55,680 --> 00:20:58,320
Speaker 1: will help. So I just I don't. I thought that

343
00:20:58,359 --> 00:21:01,520
Speaker 1: was all very super interesting. When you can find that pattern, Yeah,

344
00:21:01,600 --> 00:21:04,159
Speaker 1: that's the that's an itch. And then then it's followed

345
00:21:04,160 --> 00:21:08,000
Speaker 1: by the irresistible urge to scratch it, which Apparently research

346
00:21:08,040 --> 00:21:12,320
Speaker 1: has shown those two do not happen independently. There, they're

347
00:21:12,400 --> 00:21:15,440
Speaker 1: part of a cycle. Yes, there's that is something called

348
00:21:15,440 --> 00:21:18,879
Speaker 1: the itch scratch cycle, right, and so you have an

349
00:21:18,920 --> 00:21:23,560
Speaker 1: irresistible urge to scratch the itch. It's it's weird if

350
00:21:23,560 --> 00:21:26,080
Speaker 1: you think about it. Like, on the one hand, it

351
00:21:26,119 --> 00:21:30,840
Speaker 1: makes sense where you you sense that there's a really

352
00:21:30,880 --> 00:21:33,560
Speaker 1: hot heat source that your hand is really close to,

353
00:21:34,200 --> 00:21:36,639
Speaker 1: so you have an irresistible urge to pull it back,

354
00:21:37,280 --> 00:21:39,639
Speaker 1: But it doesn't feel like an urge. It almost feels

355
00:21:39,640 --> 00:21:44,800
Speaker 1: like an involuntary reflex. It's a scratch is almost like

356
00:21:45,960 --> 00:21:48,720
Speaker 1: I'm gonna kill this itch. I can't wait to scratch it,

357
00:21:48,800 --> 00:21:52,760
Speaker 1: Like you're almost exacting revenge on the itch for itching you. Right,

358
00:21:53,240 --> 00:21:56,159
Speaker 1: So it's scratches. It's an irresistible urge where it's like

359
00:21:56,160 --> 00:22:00,640
Speaker 1: pulling your hand back from a hot hot or something

360
00:22:01,200 --> 00:22:03,800
Speaker 1: is like an involuntary reflex. It just feels different, like

361
00:22:04,000 --> 00:22:07,159
Speaker 1: a scratches its own thing. Well it is, you know.

362
00:22:07,200 --> 00:22:09,320
Speaker 1: They kind of found that out and and go on day.

363
00:22:10,000 --> 00:22:13,439
Speaker 1: Doctor Gowan day Um pointed out something interesting too that

364
00:22:13,480 --> 00:22:15,720
Speaker 1: I never thought about, is that you can have like

365
00:22:15,760 --> 00:22:18,600
Speaker 1: that short collar rubs against your neck all day and

366
00:22:18,960 --> 00:22:21,199
Speaker 1: you might never notice it. But if there's like one

367
00:22:21,240 --> 00:22:24,639
Speaker 1: little string that's just poking one little area, that might

368
00:22:24,640 --> 00:22:27,040
Speaker 1: trigger an itch. Right, And so you would think that

369
00:22:27,160 --> 00:22:30,360
Speaker 1: you know, it's receptors are super finely tuned and they

370
00:22:30,480 --> 00:22:33,200
Speaker 1: covered just this one tiny like that's what it would

371
00:22:33,200 --> 00:22:35,840
Speaker 1: seem micron of skin as a matter of fact. No,

372
00:22:36,240 --> 00:22:42,000
Speaker 1: Apparently an INS receptor can sense it's stimuli like three

373
00:22:42,000 --> 00:22:46,800
Speaker 1: inches away from it. Yeah, so they're really sensitive. Yeah,

374
00:22:46,720 --> 00:22:52,480
Speaker 1: whereas pain receptors are that specific down to like you know, millimeters. Um.

375
00:22:52,840 --> 00:22:54,600
Speaker 1: And the other thing they found out too, is that

376
00:22:55,480 --> 00:22:57,480
Speaker 1: not only can they sense it from a few inches away,

377
00:22:57,480 --> 00:23:02,240
Speaker 1: but it's a very slow acting ing, which um as

378
00:23:02,280 --> 00:23:04,679
Speaker 1: opposed to like heat on the hand, like a candle

379
00:23:04,720 --> 00:23:09,400
Speaker 1: on your hand, almost a candle in the wind. Uh,

380
00:23:09,600 --> 00:23:12,399
Speaker 1: that's super fast. But um that that explains why an

381
00:23:12,440 --> 00:23:14,840
Speaker 1: itch like it's kind of slow to come and then

382
00:23:15,200 --> 00:23:18,399
Speaker 1: slow to resolve by scratching. Yeah, it's not like you're

383
00:23:18,440 --> 00:23:20,960
Speaker 1: scratching you're like, oh, it's all better now. Yeah, it

384
00:23:20,960 --> 00:23:23,320
Speaker 1: helps a little bit. So, so the itching is a

385
00:23:23,440 --> 00:23:27,800
Speaker 1: it's a good strategy. If you think about, um, say

386
00:23:27,880 --> 00:23:30,359
Speaker 1: you're you're there's a mosquito on you, and that's what's

387
00:23:30,400 --> 00:23:32,600
Speaker 1: making you itch. When you go to scratch it, you're

388
00:23:32,640 --> 00:23:35,159
Speaker 1: getting rid of the mosquito, maybe even smushed it or

389
00:23:35,200 --> 00:23:39,119
Speaker 1: something like that. The problem is taken care of. The

390
00:23:39,280 --> 00:23:43,919
Speaker 1: issue is is that that itch scratch cycle eventually becomes

391
00:23:43,960 --> 00:23:47,080
Speaker 1: a vicious cycle because when you scratch. This is what

392
00:23:47,119 --> 00:23:49,679
Speaker 1: they think is going on. This is another mystery with itches.

393
00:23:49,760 --> 00:23:54,359
Speaker 1: We don't understand how scratching alleviates an itch, right, or

394
00:23:54,359 --> 00:23:57,960
Speaker 1: why we scratch really right. What they think the current

395
00:23:58,480 --> 00:24:04,320
Speaker 1: hypothesis is that when scratch an itch, um you're stimulating

396
00:24:04,480 --> 00:24:08,800
Speaker 1: other receptors in the area that aren't itch receptors. So

397
00:24:09,440 --> 00:24:11,080
Speaker 1: I got that, but what does that do to sort

398
00:24:11,080 --> 00:24:14,359
Speaker 1: of like say, hey, Boddy, don't worry about that for

399
00:24:14,359 --> 00:24:16,960
Speaker 1: a minute. I think a pain receptor is now active,

400
00:24:17,080 --> 00:24:20,119
Speaker 1: right exactly. It's it's sending feedback to the brain saying

401
00:24:20,160 --> 00:24:22,719
Speaker 1: it's being taken care of. You can settle down with

402
00:24:22,760 --> 00:24:27,159
Speaker 1: the itch, right. I think the problem is that neurologically

403
00:24:27,200 --> 00:24:31,560
Speaker 1: or neurochemically, when you scratch an itch and you're activating

404
00:24:31,600 --> 00:24:34,200
Speaker 1: those pain receptors in the area pain pressure, that kind

405
00:24:34,240 --> 00:24:39,040
Speaker 1: of thing, you're causing um serotonin to be released natural

406
00:24:39,040 --> 00:24:43,040
Speaker 1: pain reliever, right, or at least mood enhancer. And what

407
00:24:43,080 --> 00:24:47,920
Speaker 1: they found is that serotonin, among other neurochemicals, actually exacerbates

408
00:24:47,960 --> 00:24:51,360
Speaker 1: the itch sensation. So you're itch not only comes back,

409
00:24:51,400 --> 00:24:54,080
Speaker 1: it gets worse. So you go to scratch it again,

410
00:24:54,119 --> 00:24:56,200
Speaker 1: and then the same thing happens over and over again.

411
00:24:56,200 --> 00:24:59,720
Speaker 1: That's the itch scratch cycle, which it's not the best

412
00:24:59,760 --> 00:25:03,199
Speaker 1: c go around, No, you get better cycles. Not a

413
00:25:03,200 --> 00:25:11,000
Speaker 1: bad band name, Yeah, it's okay, cute maybe Prague Folk

414
00:25:11,119 --> 00:25:14,000
Speaker 1: Prague They well, they'd have to be German, probably German

415
00:25:14,080 --> 00:25:20,920
Speaker 1: folk pog Okay. Another interesting thing they learned too was that, um,

416
00:25:21,040 --> 00:25:23,440
Speaker 1: I guess we're kind of jumping around, but who cares? Right,

417
00:25:24,480 --> 00:25:27,720
Speaker 1: if you scratch, you don't have to scratch the point

418
00:25:27,840 --> 00:25:31,160
Speaker 1: of the itch to relieve it, apparently, right, Like if

419
00:25:31,200 --> 00:25:34,679
Speaker 1: you have had that itch on my right forearm and

420
00:25:34,720 --> 00:25:36,920
Speaker 1: I could scratch, maybe don't you have to be the

421
00:25:37,000 --> 00:25:40,040
Speaker 1: left forearms. It's not like you have to mirror it. Um,

422
00:25:40,080 --> 00:25:42,280
Speaker 1: but I could scratch like my neck and apparently that

423
00:25:42,359 --> 00:25:45,320
Speaker 1: might help relieve it. Yeah, I tried. It didn't work

424
00:25:45,359 --> 00:25:49,760
Speaker 1: for me. But I think the reason why there's that's

425
00:25:49,960 --> 00:25:53,680
Speaker 1: it's possible that it could have that effect. Is supposedly

426
00:25:54,600 --> 00:26:00,720
Speaker 1: scratching also UM activates like your pleasure center. Yeah, you

427
00:26:00,800 --> 00:26:04,000
Speaker 1: bet it does. But there's different different places where you're

428
00:26:04,000 --> 00:26:07,399
Speaker 1: scratching on your body UM have different amounts of pleasure

429
00:26:07,400 --> 00:26:10,640
Speaker 1: associated with them. Did you know that? I mean, I guess,

430
00:26:10,880 --> 00:26:13,760
Speaker 1: I guess so. But interesting, Well yeah, but I mean

431
00:26:13,760 --> 00:26:17,240
Speaker 1: think about it. It's like if you scratch your scratch

432
00:26:17,320 --> 00:26:21,000
Speaker 1: your like you're clavical, who cares, it's nothing, right, But

433
00:26:21,040 --> 00:26:23,760
Speaker 1: then you scratch like your head right above and behind

434
00:26:23,760 --> 00:26:26,639
Speaker 1: your ear, it's great. Well, and they I think they

435
00:26:26,680 --> 00:26:30,080
Speaker 1: did find that, like you're back in your ankles supposedly

436
00:26:30,200 --> 00:26:33,719
Speaker 1: or some of the most rewarding places to scratch exactly.

437
00:26:34,040 --> 00:26:37,160
Speaker 1: And I I don't know, I've never really thought about

438
00:26:37,160 --> 00:26:41,680
Speaker 1: the ankles, but um my mom would give me back

439
00:26:41,720 --> 00:26:45,400
Speaker 1: scratches when I was a kid, and it was always

440
00:26:45,440 --> 00:26:50,600
Speaker 1: like one of my favorite things ever. And so I

441
00:26:50,640 --> 00:26:52,399
Speaker 1: don't get those anymore now that i'm a grown up,

442
00:26:52,400 --> 00:26:57,399
Speaker 1: because that's gross. You know, I'm scratch my back right,

443
00:26:57,480 --> 00:27:01,840
Speaker 1: I'm forty six years old, lay down. Uh, but yeah,

444
00:27:01,840 --> 00:27:04,200
Speaker 1: it was like I think I preferred to backscratch to

445
00:27:04,240 --> 00:27:07,360
Speaker 1: a back rub, even when I was younger, but now

446
00:27:07,520 --> 00:27:10,679
Speaker 1: you know, massage is probably way better. But if they

447
00:27:10,840 --> 00:27:13,720
Speaker 1: if a masseuse could include a little back scratch in there,

448
00:27:14,920 --> 00:27:18,159
Speaker 1: get ready for a huge tip for me. Yeah, or

449
00:27:18,240 --> 00:27:21,200
Speaker 1: does that? What is that sexual? I think it crosses

450
00:27:21,240 --> 00:27:25,159
Speaker 1: a line once they're potentially clawing away skin cells. I

451
00:27:25,240 --> 00:27:30,400
Speaker 1: think that's so longer in the Masseus range or Messur range. Yeah,

452
00:27:30,680 --> 00:27:34,439
Speaker 1: I get that. One skin cells are involved under the nails,

453
00:27:34,800 --> 00:27:38,800
Speaker 1: then you're a murder suspect, right exactly? All right, Well,

454
00:27:38,840 --> 00:27:41,119
Speaker 1: should we take another break and talk a little bit

455
00:27:41,160 --> 00:28:05,280
Speaker 1: about one of the most distressing, uh articles I've ever read? Uh?

456
00:28:06,320 --> 00:28:08,520
Speaker 1: All right, so we've referenced this article from the New

457
00:28:08,560 --> 00:28:12,840
Speaker 1: Yorker from Dr atul go on day and Um, he

458
00:28:12,920 --> 00:28:15,359
Speaker 1: talked a lot about itching and just had good information

459
00:28:15,400 --> 00:28:20,560
Speaker 1: on the science of it all. But most of the

460
00:28:20,680 --> 00:28:25,920
Speaker 1: article was focused on a patient, a woman in Massachusetts.

461
00:28:26,680 --> 00:28:31,160
Speaker 1: H that they named him for the article just M

462
00:28:31,200 --> 00:28:34,440
Speaker 1: the letter M. In other words, you know, she's anonymous, uh.

463
00:28:34,440 --> 00:28:36,119
Speaker 1: And I think she was anonymous because she kind of

464
00:28:36,160 --> 00:28:40,960
Speaker 1: had a rough go after her divorce. Um, she ended

465
00:28:41,040 --> 00:28:46,040
Speaker 1: up getting HIV from getting on heroin kind of spun out,

466
00:28:46,080 --> 00:28:49,560
Speaker 1: it seems like. But then got her life back by

467
00:28:49,600 --> 00:28:53,080
Speaker 1: all accounts, but ended up getting shingles as a result

468
00:28:53,120 --> 00:28:58,360
Speaker 1: of HIV complications, and the shingles went away, but the

469
00:28:58,400 --> 00:29:01,080
Speaker 1: itching did not to the least. Yeah, I think the

470
00:29:01,160 --> 00:29:05,200
Speaker 1: itching came after the shingles even and that first her

471
00:29:05,720 --> 00:29:08,880
Speaker 1: her physicians were like, well, I mean you must have

472
00:29:09,560 --> 00:29:14,360
Speaker 1: you damage some nerves in there, so t s for you,

473
00:29:14,520 --> 00:29:19,520
Speaker 1: I guess, um. And then eventually after treating it like

474
00:29:19,640 --> 00:29:24,120
Speaker 1: all these different ways and it's still being scratching, they said, okay,

475
00:29:24,160 --> 00:29:28,440
Speaker 1: you're crazy, how about that? And she said, well, whatever,

476
00:29:28,680 --> 00:29:31,320
Speaker 1: I still have this ditch. Do whatever you need to

477
00:29:31,320 --> 00:29:34,520
Speaker 1: to treat it, because I'm literally scratching this itch in

478
00:29:34,600 --> 00:29:37,080
Speaker 1: my sleep. It was on her scalp, wasn't it. It

479
00:29:37,160 --> 00:29:39,600
Speaker 1: was on her head, and she um, she kind of

480
00:29:39,640 --> 00:29:42,480
Speaker 1: managed to control it during the day, but like you said,

481
00:29:42,520 --> 00:29:44,840
Speaker 1: at night, she couldn't control it to the point where

482
00:29:44,880 --> 00:29:47,440
Speaker 1: I think she was like restrained in her sleep. That

483
00:29:47,560 --> 00:29:52,160
Speaker 1: came after after they realized it's a problem because your

484
00:29:52,160 --> 00:29:55,640
Speaker 1: brain is using out of your head. Can you believe

485
00:29:55,680 --> 00:29:58,720
Speaker 1: that she scratched her scalp so much that she scratched

486
00:29:58,720 --> 00:30:01,680
Speaker 1: through her skull and she went into her doctor one

487
00:30:01,760 --> 00:30:05,400
Speaker 1: day and said they've got like this green fluid coming down.

488
00:30:05,680 --> 00:30:10,720
Speaker 1: And then apparently the doctor didn't even say anything, he

489
00:30:11,000 --> 00:30:13,560
Speaker 1: was just she or she was like, excuse me, went

490
00:30:13,640 --> 00:30:15,840
Speaker 1: and called an ambulance and came back and said please

491
00:30:15,960 --> 00:30:18,360
Speaker 1: lay down and don't talk or move or do anything else.

492
00:30:18,400 --> 00:30:20,760
Speaker 1: And they finally told her after she was at the

493
00:30:20,800 --> 00:30:23,760
Speaker 1: e er, you scratched through to your brain, like that's

494
00:30:23,800 --> 00:30:27,000
Speaker 1: your brain you're touching right now. Doctors like very interesting

495
00:30:27,040 --> 00:30:32,080
Speaker 1: and just give me a second here, or oh my god.

496
00:30:33,160 --> 00:30:35,960
Speaker 1: Uh well, they gathered up all the other doctors and

497
00:30:36,040 --> 00:30:38,920
Speaker 1: nurses like sure, yeah, you gotta come see this. She said.

498
00:30:38,960 --> 00:30:42,080
Speaker 1: Also in this article, um, she said that she had

499
00:30:42,160 --> 00:30:47,200
Speaker 1: a uh what do they call him a roommate at

500
00:30:47,400 --> 00:30:53,680
Speaker 1: h Okay a roommate, So, um, she had a roommate.

501
00:30:53,800 --> 00:30:56,800
Speaker 1: While she was like, they treated it, gave her a

502
00:30:56,840 --> 00:31:00,640
Speaker 1: skin graft, and then she she she's scratched away the

503
00:31:00,720 --> 00:31:04,800
Speaker 1: king and then um, they finally were like, okay, you're

504
00:31:04,800 --> 00:31:08,200
Speaker 1: going to an asylum and she's like do they even

505
00:31:08,240 --> 00:31:09,920
Speaker 1: call it that anymore? And they're like, just shut up,

506
00:31:10,360 --> 00:31:13,560
Speaker 1: and they put her in this asylum and restrained her,

507
00:31:13,600 --> 00:31:15,720
Speaker 1: like you said, while she was sleeping, and she had

508
00:31:15,760 --> 00:31:18,040
Speaker 1: a roommate in there. She said in the article she

509
00:31:18,360 --> 00:31:20,640
Speaker 1: if she heard didn't survive. He had scratched through his

510
00:31:20,680 --> 00:31:26,400
Speaker 1: carotid artery and died blood death. Um, so they never

511
00:31:26,440 --> 00:31:29,320
Speaker 1: really got to the bottom of this. She finally got

512
00:31:29,720 --> 00:31:33,240
Speaker 1: a doctor. Like, the doctors are like, it's something that

513
00:31:33,440 --> 00:31:34,920
Speaker 1: had to do with the shingles. This is what we

514
00:31:34,960 --> 00:31:39,760
Speaker 1: think happens. That her doctors that the the nerve endings

515
00:31:39,800 --> 00:31:43,640
Speaker 1: around the area where she had shingles were so devastated

516
00:31:43,680 --> 00:31:46,000
Speaker 1: by the shingles that there were just a couple of

517
00:31:46,040 --> 00:31:48,640
Speaker 1: nerve endings left and it just so happened that they

518
00:31:48,640 --> 00:31:52,960
Speaker 1: were itch receptors itch itch, um, yeah, it receptor, and

519
00:31:53,080 --> 00:31:56,640
Speaker 1: that those were like really exacerbated by the fact that

520
00:31:56,720 --> 00:32:00,440
Speaker 1: there was no other competing sensations. If so, fact though,

521
00:32:00,680 --> 00:32:03,720
Speaker 1: there's your problem, right, So they said, well, let's we'll

522
00:32:03,800 --> 00:32:06,280
Speaker 1: just cut the main nerve to the to your face

523
00:32:06,400 --> 00:32:08,400
Speaker 1: and that should solve the problem. They cut the main

524
00:32:08,520 --> 00:32:12,360
Speaker 1: nerve to her face and um, she said, frank, yeah,

525
00:32:13,000 --> 00:32:15,040
Speaker 1: and then the itch came back and she's like, you

526
00:32:15,120 --> 00:32:17,360
Speaker 1: have to be kidding me. So finally she met a doctor.

527
00:32:17,400 --> 00:32:21,280
Speaker 1: He said, I don't think it's your your receptors or

528
00:32:21,360 --> 00:32:25,680
Speaker 1: the nerve transmission. I think it's your brain, not psychologically.

529
00:32:25,720 --> 00:32:28,400
Speaker 1: I don't think it's a psychosis. I think there's that

530
00:32:28,600 --> 00:32:31,479
Speaker 1: the actual itch signaling your brain is being set off

531
00:32:31,560 --> 00:32:36,000
Speaker 1: without any stimulation or transmission going on. And UM, apparently

532
00:32:36,120 --> 00:32:39,120
Speaker 1: she was right, but then they were like, good luck

533
00:32:39,200 --> 00:32:42,680
Speaker 1: treating that. You know. I didn't see much follow up

534
00:32:42,720 --> 00:32:45,480
Speaker 1: on this. I did read one article that UM follow

535
00:32:45,560 --> 00:32:47,440
Speaker 1: up with Dr Gawande because there were a lot of

536
00:32:47,520 --> 00:32:51,320
Speaker 1: skeptics after that article came out that said, it's impossible

537
00:32:51,440 --> 00:32:53,800
Speaker 1: with your fingernail because she said she didn't use an implement.

538
00:32:54,000 --> 00:32:56,040
Speaker 1: It's not like she got out of metal file to

539
00:32:56,200 --> 00:32:59,560
Speaker 1: scratch through your skull. And he said that his theory

540
00:32:59,680 --> 00:33:03,280
Speaker 1: was that bacteria it became infected, it had eaten it

541
00:33:03,400 --> 00:33:08,560
Speaker 1: away such that the skull became soft turn into much yeah. Uh.

542
00:33:08,640 --> 00:33:10,520
Speaker 1: And then people also said, and you know, you don't

543
00:33:10,560 --> 00:33:13,400
Speaker 1: have men and women in the same room in hospitals

544
00:33:13,520 --> 00:33:17,240
Speaker 1: or asylums. That's that's false. And he said, uh, that

545
00:33:17,360 --> 00:33:21,200
Speaker 1: it was like the room next door. Um, and quit

546
00:33:21,320 --> 00:33:24,880
Speaker 1: being pedantical. Man. I think people just didn't believe it.

547
00:33:24,920 --> 00:33:26,920
Speaker 1: So all these folks rode into the new Yorker. So

548
00:33:27,280 --> 00:33:30,600
Speaker 1: those coastal elites said, no way, They said, a tool,

549
00:33:30,920 --> 00:33:34,520
Speaker 1: a tool, come on. So the the idea though that

550
00:33:35,160 --> 00:33:38,320
Speaker 1: even if this woman was hypothetical, I think to a

551
00:33:38,440 --> 00:33:42,360
Speaker 1: Gwanda is pretty upstanding cat and didn't make this up.

552
00:33:42,760 --> 00:33:46,320
Speaker 1: But even if I say she was hypothetical, her problem.

553
00:33:46,920 --> 00:33:49,800
Speaker 1: What the doctors initially thought it was, was that she

554
00:33:50,000 --> 00:33:54,440
Speaker 1: had a neuropathic kitch, type of chronic kitch. But then

555
00:33:54,480 --> 00:33:58,280
Speaker 1: the doctor who apparently figured it all out, said no, no, no,

556
00:33:58,720 --> 00:34:02,120
Speaker 1: it's a neurogenic another type of chronic catch, and it

557
00:34:02,240 --> 00:34:05,240
Speaker 1: has to do with whether it's the brain going off

558
00:34:05,440 --> 00:34:09,000
Speaker 1: or the nerve transmissions going off. Either way, you don't

559
00:34:09,040 --> 00:34:14,680
Speaker 1: actually have an itch, although you're experiencing the itch sensation well.

560
00:34:14,719 --> 00:34:16,600
Speaker 1: And they also then said at some point she had

561
00:34:16,600 --> 00:34:19,520
Speaker 1: a psychogenic itch. Right, So they basically covered three out

562
00:34:19,560 --> 00:34:24,560
Speaker 1: of the four kinds of itches, the last one being uh, man,

563
00:34:24,680 --> 00:34:27,719
Speaker 1: that's such a hard time per receptive, and that's what

564
00:34:27,800 --> 00:34:29,840
Speaker 1: you get from like a mosquito bite or if you

565
00:34:29,920 --> 00:34:32,560
Speaker 1: have a skin disorder like exema or something. So they

566
00:34:32,640 --> 00:34:35,880
Speaker 1: basically ruled out the most common one and at various

567
00:34:35,880 --> 00:34:38,320
Speaker 1: stages said, now you've got this other one for the

568
00:34:38,400 --> 00:34:42,160
Speaker 1: other three finally, and then again they said, we don't

569
00:34:42,239 --> 00:34:43,920
Speaker 1: there's really nothing we can do to treat it. The

570
00:34:43,960 --> 00:34:46,680
Speaker 1: one that they've got down pretty well is per receptive.

571
00:34:47,239 --> 00:34:49,320
Speaker 1: We've got all sorts of stuff to treat that because

572
00:34:49,680 --> 00:34:53,680
Speaker 1: that's that's basically histamine is being released and your your

573
00:34:53,719 --> 00:34:57,400
Speaker 1: skin is itching. So you can treat histamines with anti histamines,

574
00:34:57,920 --> 00:35:00,399
Speaker 1: you can reduce that response and then you're itch will

575
00:35:00,440 --> 00:35:03,200
Speaker 1: go away. Well, I took a ben a drill at night,

576
00:35:03,880 --> 00:35:06,920
Speaker 1: and they also make this ben a drill spray, a

577
00:35:07,000 --> 00:35:10,520
Speaker 1: topical spray that just it really helps. So between that

578
00:35:10,680 --> 00:35:13,759
Speaker 1: and cortisone and then the bene drill at night, I

579
00:35:14,000 --> 00:35:17,239
Speaker 1: did okay, and there's awesome showers. So the like the

580
00:35:17,360 --> 00:35:21,680
Speaker 1: pro receptive itch, we've got treatment for basically the other three,

581
00:35:21,960 --> 00:35:25,759
Speaker 1: you're you're in trouble. It turns out, as far as

582
00:35:25,800 --> 00:35:28,200
Speaker 1: it stands right now, maybe five or ten years from now,

583
00:35:28,920 --> 00:35:32,319
Speaker 1: there'll be something. Apparently there's a lot of movement right

584
00:35:32,360 --> 00:35:37,239
Speaker 1: now on treating this stuff, but it's like they're having

585
00:35:37,360 --> 00:35:41,480
Speaker 1: to figure out how to block some really otherwise important

586
00:35:41,560 --> 00:35:45,680
Speaker 1: chemicals in the body, like that m p p B. Right, Yeah,

587
00:35:45,719 --> 00:35:47,680
Speaker 1: that one, what does it can help, can regulate your

588
00:35:47,680 --> 00:35:51,680
Speaker 1: blood pressure as well, So they off, right, just turn

589
00:35:51,760 --> 00:35:54,000
Speaker 1: off the gene that produces that. You won't itch, but

590
00:35:54,080 --> 00:35:57,759
Speaker 1: you might die early. Not worth it. The one that really,

591
00:35:58,080 --> 00:36:01,759
Speaker 1: I mean, they're all sad, but the psychogenic when you

592
00:36:01,800 --> 00:36:04,360
Speaker 1: have a mental illness where you feel like parasites and

593
00:36:04,440 --> 00:36:09,360
Speaker 1: bugs on your skin. Um, they remember our Morgelon's disease. Yeah,

594
00:36:10,160 --> 00:36:12,360
Speaker 1: how did you said it? More gallons? Right? And I

595
00:36:12,440 --> 00:36:15,600
Speaker 1: said Morgelon, I can't remember. I know that I said

596
00:36:15,640 --> 00:36:19,200
Speaker 1: it the way everyone else else says it, though, that's

597
00:36:19,200 --> 00:36:22,680
Speaker 1: all I remember, Morgan laws, that's right, That's how I

598
00:36:22,760 --> 00:36:25,200
Speaker 1: said it. Man. But all this stuff just had so

599
00:36:25,280 --> 00:36:28,520
Speaker 1: much empathy for m Yeah, and wanted to follow up

600
00:36:28,600 --> 00:36:32,560
Speaker 1: so bad to see how she was doing, you know. Yeah,

601
00:36:33,719 --> 00:36:37,840
Speaker 1: and if she kept scratching holes in her skull, I

602
00:36:38,360 --> 00:36:42,120
Speaker 1: don't know, geez. So there's I read another article called

603
00:36:42,200 --> 00:36:46,040
Speaker 1: Accidental Therapists. It's by a guy named Eric Brudman, and

604
00:36:46,120 --> 00:36:49,200
Speaker 1: it was published on a website called stat and it's

605
00:36:49,200 --> 00:36:55,040
Speaker 1: all about delusional parasite parasitosis but how it's treated sometimes

606
00:36:55,200 --> 00:37:01,040
Speaker 1: by um entomologists, you know, like those um extension services

607
00:37:01,080 --> 00:37:04,600
Speaker 1: at universities, here in the US, like state universities have

608
00:37:04,680 --> 00:37:08,520
Speaker 1: where to call extension services where like uh um, the

609
00:37:08,640 --> 00:37:12,080
Speaker 1: scientists will basically be there for the public to come

610
00:37:12,200 --> 00:37:15,680
Speaker 1: talk to about whatever. Usually it's like household stuff, for

611
00:37:16,000 --> 00:37:20,359
Speaker 1: farm stuff, something like that. Um. And apparently in tomologists

612
00:37:20,400 --> 00:37:22,359
Speaker 1: frequently are approached with people who are like, I've got

613
00:37:22,440 --> 00:37:24,880
Speaker 1: these bugs like crawling all over me. Here's a sample

614
00:37:24,920 --> 00:37:27,200
Speaker 1: of them. And it turns out it's like carpet fiber

615
00:37:27,320 --> 00:37:29,759
Speaker 1: or something like that, and these people just can't stop

616
00:37:29,840 --> 00:37:32,480
Speaker 1: itching or whatever. But it turns out they have a delusion,

617
00:37:32,520 --> 00:37:36,759
Speaker 1: they don't actually have parasites. My question is, is that

618
00:37:36,880 --> 00:37:39,439
Speaker 1: our understanding of it now and in five or ten years,

619
00:37:39,520 --> 00:37:42,120
Speaker 1: where you know that they had neurogenic itches and we

620
00:37:42,239 --> 00:37:44,680
Speaker 1: just treated them like they were crazy even though they weren't,

621
00:37:45,280 --> 00:37:47,480
Speaker 1: and it's gonna be like a real blemish on the

622
00:37:47,600 --> 00:37:53,600
Speaker 1: history of neuroscience, or will this idea of psychogenic itches

623
00:37:54,120 --> 00:37:57,080
Speaker 1: you know? Hold up? Yeah, I wonder did you ever

624
00:37:57,160 --> 00:38:00,239
Speaker 1: see the Todd Haynes movie Safe with Julianne Moore. No,

625
00:38:00,680 --> 00:38:03,800
Speaker 1: it was one of his first movies after the Karen

626
00:38:03,840 --> 00:38:07,160
Speaker 1: Carpenter thing he did. Uh that wasn't like, I mean,

627
00:38:07,200 --> 00:38:09,319
Speaker 1: it was a real movie, but it wasn't released. Um,

628
00:38:09,400 --> 00:38:11,799
Speaker 1: but Safe was very disturbing. It was about a woman

629
00:38:11,840 --> 00:38:16,040
Speaker 1: who kind of slowly drifted into madness from believing that

630
00:38:16,600 --> 00:38:20,920
Speaker 1: the world was poisoning her and like household chemicals and everything,

631
00:38:21,000 --> 00:38:23,839
Speaker 1: and it kind of started slow and eventually she ended

632
00:38:23,880 --> 00:38:28,040
Speaker 1: up at this kind of safe camp for people like her. Um,

633
00:38:28,640 --> 00:38:31,480
Speaker 1: very distressing movie and one of her first movies too.

634
00:38:31,760 --> 00:38:34,000
Speaker 1: Have to check it out. Yeah, it's really good. It's old,

635
00:38:34,760 --> 00:38:38,320
Speaker 1: Yeah it was. It was early nineties. I think I

636
00:38:38,440 --> 00:38:41,000
Speaker 1: know you're talking about. It's called the Road to Wellville.

637
00:38:42,280 --> 00:38:45,319
Speaker 1: Is that what you mean? It's called safe? Check it out. Yeah,

638
00:38:45,360 --> 00:38:47,560
Speaker 1: it's good, very distressing. I'm trying to think of anything

639
00:38:47,680 --> 00:38:50,840
Speaker 1: that wasn't necessarily itching. But it was just like that

640
00:38:50,960 --> 00:38:54,080
Speaker 1: psychogenic thing of like I think everything in my house

641
00:38:54,200 --> 00:38:56,440
Speaker 1: is killing me. Yeah. I mean, have you ever like

642
00:38:56,640 --> 00:38:59,719
Speaker 1: stopped and thought about something and thought, there's there's the

643
00:38:59,760 --> 00:39:02,319
Speaker 1: path the madness right there I'm staring down at right now.

644
00:39:02,960 --> 00:39:06,480
Speaker 1: I should probably not keep thinking about this. I don't

645
00:39:06,520 --> 00:39:09,080
Speaker 1: really get like that. Oh no, no, I'm very easily

646
00:39:09,719 --> 00:39:14,080
Speaker 1: kind of led onto the next shiny thing, I guess. Yeah, yeah,

647
00:39:14,239 --> 00:39:18,319
Speaker 1: basically that's probably for the best it is. It has

648
00:39:18,360 --> 00:39:22,680
Speaker 1: its drawbacks. So, uh, what else you got? Well, one

649
00:39:22,680 --> 00:39:26,880
Speaker 1: thing it says in here is that, um, having someone

650
00:39:27,040 --> 00:39:31,000
Speaker 1: else scratch your itch does apparently does not do the trick.

651
00:39:31,440 --> 00:39:33,800
Speaker 1: So you have to scratch your own itch. Yeah, I

652
00:39:33,840 --> 00:39:37,399
Speaker 1: mean somebody can like obviously, like you know, if you're

653
00:39:37,400 --> 00:39:40,080
Speaker 1: like a little left a little left up up up. Yeah.

654
00:39:40,120 --> 00:39:45,239
Speaker 1: See I don't work. Oh man, not you that them saying, right, Like,

655
00:39:45,320 --> 00:39:47,200
Speaker 1: I think it definitely helps. I think what they're saying

656
00:39:47,360 --> 00:39:50,960
Speaker 1: is is it doesn't have quite the same relieving properties

657
00:39:50,960 --> 00:39:53,600
Speaker 1: as if you do it yourself. Yeah, and if you

658
00:39:53,680 --> 00:39:55,719
Speaker 1: could reach that area of your back, it would be

659
00:39:55,840 --> 00:39:59,719
Speaker 1: better than that. I got a pretty good backscratcher now though.

660
00:40:00,000 --> 00:40:03,160
Speaker 1: Oh yeah, it's a made of bamboo. No, it's it's metal,

661
00:40:04,040 --> 00:40:07,680
Speaker 1: but it's telescoping, so it's not you know, two ft long,

662
00:40:08,719 --> 00:40:12,120
Speaker 1: but it can be. But it's metal. Yeah. It looks

663
00:40:12,160 --> 00:40:14,600
Speaker 1: like a like what are the bear claw? Not the

664
00:40:14,600 --> 00:40:18,800
Speaker 1: pastry but a real bear claw which actually looks like

665
00:40:18,920 --> 00:40:21,040
Speaker 1: the pastry. Man. I guess that's why they call it that.

666
00:40:21,600 --> 00:40:23,680
Speaker 1: I never thought about that. Why do you think that

667
00:40:23,840 --> 00:40:27,399
Speaker 1: was called that? I actually call it a bear paw.

668
00:40:27,520 --> 00:40:30,520
Speaker 1: It looks more like a bear paw. I'm try and

669
00:40:30,560 --> 00:40:33,279
Speaker 1: bring that, bring that around unless you get somebody who

670
00:40:33,440 --> 00:40:36,200
Speaker 1: like really goes the extra mile and puts almonds on

671
00:40:36,320 --> 00:40:39,279
Speaker 1: the tips to make it look like the claw, yes,

672
00:40:40,360 --> 00:40:44,040
Speaker 1: and not just haphazardly scattered about the bear paw. That's

673
00:40:44,080 --> 00:40:46,880
Speaker 1: the difference between a baker who loves their job the

674
00:40:46,960 --> 00:40:50,440
Speaker 1: one who's just in it for the money. Yeah. Uh,

675
00:40:51,080 --> 00:40:54,040
Speaker 1: A couple more things, Charles. Like we said, there's a

676
00:40:54,480 --> 00:40:58,520
Speaker 1: still plenty of mysteries around itches. Why say, does a

677
00:40:58,760 --> 00:41:03,840
Speaker 1: feather tickle some times but it's other times? Big question?

678
00:41:04,480 --> 00:41:08,480
Speaker 1: They don't know, right, but I'd like to know. Well,

679
00:41:08,800 --> 00:41:13,319
Speaker 1: maybe the Germans will get active on this again, they're

680
00:41:13,320 --> 00:41:15,920
Speaker 1: the only ones who can solve it. Though only the

681
00:41:16,000 --> 00:41:20,640
Speaker 1: Germans can save us. You got anything else? No, I don't.

682
00:41:22,080 --> 00:41:25,800
Speaker 1: I don't either. Itching nice work, thanks man, same do you?

683
00:41:26,120 --> 00:41:28,400
Speaker 1: Thank you? And you haven't scratched in a while, so no,

684
00:41:28,640 --> 00:41:32,279
Speaker 1: I'm actually um, I've been scratching the same spot and

685
00:41:32,320 --> 00:41:34,839
Speaker 1: it's starting to get a little tender, so I'm stopping. Man,

686
00:41:34,920 --> 00:41:37,400
Speaker 1: there's nothing worse than a movie, and I've seen it.

687
00:41:37,920 --> 00:41:39,360
Speaker 1: I feel like I've seen this a few times in

688
00:41:39,480 --> 00:41:43,480
Speaker 1: movies where someone is compulsively like scratching until it becomes

689
00:41:43,480 --> 00:41:45,840
Speaker 1: a sore, and then they're scratching it. It's just like

690
00:41:46,520 --> 00:41:51,840
Speaker 1: through their brain. Well, yeah, so I guess the moral

691
00:41:51,920 --> 00:41:55,600
Speaker 1: of this one is what would Tom Petty do? I'll

692
00:41:55,600 --> 00:41:59,440
Speaker 1: ask him tomorrow. If you want to know more about

693
00:41:59,560 --> 00:42:02,400
Speaker 1: itching or what Tom Petty would do, you can type

694
00:42:02,440 --> 00:42:04,839
Speaker 1: those words in the search part how stuff works dot com.

695
00:42:05,280 --> 00:42:11,719
Speaker 1: And since I said search far, it's time for listener mail. Uh.

696
00:42:11,960 --> 00:42:15,400
Speaker 1: I'm gonna call this one of the many emails we

697
00:42:15,480 --> 00:42:18,560
Speaker 1: got on the swearing episode. Do you notice that people

698
00:42:18,840 --> 00:42:22,160
Speaker 1: really seem to like that one? A lot of response

699
00:42:22,960 --> 00:42:29,520
Speaker 1: from mostly from fellow potty mouse, which we're very filthy

700
00:42:29,560 --> 00:42:32,439
Speaker 1: emails too, which were great, and I responded in turn

701
00:42:32,520 --> 00:42:35,520
Speaker 1: by cursing at them and my replies, which I hope

702
00:42:35,560 --> 00:42:39,480
Speaker 1: they enjoyed in all caps M No, I didn't want

703
00:42:39,520 --> 00:42:43,560
Speaker 1: to be too aggressive. UM. So this is from Emily Allen. Hey, guys,

704
00:42:43,600 --> 00:42:47,280
Speaker 1: a long time listener, first time writing in UM writing

705
00:42:47,320 --> 00:42:49,720
Speaker 1: about swearing. I should start by saying that it's funny

706
00:42:49,719 --> 00:42:52,360
Speaker 1: I'm writing about this episode because I almost never curse,

707
00:42:52,840 --> 00:42:56,240
Speaker 1: and when I do, it's normally not a very offensive swear. However,

708
00:42:56,480 --> 00:42:58,399
Speaker 1: your intro made me think of something interesting I wanted

709
00:42:58,440 --> 00:43:01,120
Speaker 1: to share. You talked about how really censor yourself during

710
00:43:01,160 --> 00:43:03,680
Speaker 1: recording in order to keep your show family friendly, and

711
00:43:03,800 --> 00:43:06,200
Speaker 1: got me thinking about how our jobs really shape our vocabulary,

712
00:43:06,480 --> 00:43:09,440
Speaker 1: how we express ourselves. I noticed a major change in

713
00:43:09,480 --> 00:43:12,759
Speaker 1: the way I speak since becoming a teacher, primarily teach

714
00:43:12,880 --> 00:43:15,439
Speaker 1: kindergarten to second grade students, and I found this really

715
00:43:15,520 --> 00:43:18,239
Speaker 1: changed the way I expressed myself. For example, I try

716
00:43:18,280 --> 00:43:21,959
Speaker 1: to avoid even saying things are dumb or stupid around kids.

717
00:43:22,239 --> 00:43:25,120
Speaker 1: Will often say, well, isn't that silly? Instead? Uh. This

718
00:43:25,239 --> 00:43:27,400
Speaker 1: works in the classroom, but I often get laughs from

719
00:43:27,480 --> 00:43:31,440
Speaker 1: friends and family when I refer to a situation as silly,

720
00:43:32,560 --> 00:43:35,440
Speaker 1: like a disagreement with a colleague or something a politician does.

721
00:43:38,320 --> 00:43:40,239
Speaker 1: There are other expressions I use with the kids that

722
00:43:40,320 --> 00:43:43,440
Speaker 1: often slip into regular conversation as well. The most embarrassing

723
00:43:43,800 --> 00:43:46,440
Speaker 1: when I am out and excuse myself to go potty.

724
00:43:47,280 --> 00:43:49,759
Speaker 1: That always gets a laugh. Anyway, I just wanted to

725
00:43:49,760 --> 00:43:51,160
Speaker 1: share and thank you for all the great work you do.

726
00:43:51,760 --> 00:43:54,160
Speaker 1: Learned so much from listening each week, and I'm always

727
00:43:54,200 --> 00:43:58,200
Speaker 1: excited to see the new episode offerings every Tuesday and Thursday.

728
00:43:58,719 --> 00:44:04,960
Speaker 1: That is from Emily Allen. Thank you ms Allen, very silly. Uh,

729
00:44:05,280 --> 00:44:08,319
Speaker 1: that was a very nice email. Uh. If you want
