00:00:03,080 --> 00:00:06,000
Speaker 1: Welcome to stuff to Blow your Mind from how Stuff

2
00:00:06,000 --> 00:00:13,960
Speaker 1: Works dot com. Hey, welcome to Stuff to all your Mind.

3
00:00:14,000 --> 00:00:16,840
Speaker 1: My name is Robert Lamb and I'm Julie Douglas. Julie,

4
00:00:16,880 --> 00:00:18,840
Speaker 1: what does a fire breathing dragon have to do with

5
00:00:18,840 --> 00:00:21,800
Speaker 1: the human digestion system? A lot, it turns out, and

6
00:00:21,880 --> 00:00:23,840
Speaker 1: in fact, it has a lot to do with gas

7
00:00:24,079 --> 00:00:27,080
Speaker 1: and belching. And you guys know that we we promised

8
00:00:27,120 --> 00:00:31,000
Speaker 1: that we would roll out an episode about inflate us,

9
00:00:31,120 --> 00:00:35,000
Speaker 1: about gas, the toutes parts, you name it. If you promised,

10
00:00:35,040 --> 00:00:37,879
Speaker 1: it was like a blood oath to our listeners that

11
00:00:38,000 --> 00:00:40,080
Speaker 1: we would do a fart episode for everyone. But no

12
00:00:40,159 --> 00:00:42,040
Speaker 1: one asked for by the way, no well no one

13
00:00:42,080 --> 00:00:45,319
Speaker 1: ever asked for it, but it happens, and so here

14
00:00:45,320 --> 00:00:49,360
Speaker 1: it is an entire episode devoted to the interesting science

15
00:00:50,040 --> 00:00:54,360
Speaker 1: of of cutting one as it were. You say that

16
00:00:54,400 --> 00:00:57,319
Speaker 1: with a question mark. I think it's you know, it's

17
00:00:57,360 --> 00:00:59,520
Speaker 1: definitely interesting science. I think it comes down to the

18
00:00:59,560 --> 00:01:01,880
Speaker 1: individual a listener, I mean, what what is your individual

19
00:01:01,920 --> 00:01:06,039
Speaker 1: relationship with gas? And are you the type of person

20
00:01:06,080 --> 00:01:08,720
Speaker 1: who is repelled enough to where no amount of interesting

21
00:01:08,760 --> 00:01:12,800
Speaker 1: science is really going to make you respect flateus in

22
00:01:12,840 --> 00:01:14,840
Speaker 1: any way or do you or do you? Are you

23
00:01:14,840 --> 00:01:17,399
Speaker 1: already totally on board? And in science the coding of

24
00:01:17,440 --> 00:01:21,160
Speaker 1: science can only make flateus all the more exciting. My

25
00:01:21,240 --> 00:01:23,560
Speaker 1: feeling is that everybody does it, so everybody should have

26
00:01:23,600 --> 00:01:26,679
Speaker 1: an interest in it. Well, everybody does it, but people

27
00:01:26,720 --> 00:01:29,160
Speaker 1: do it to different degrees, and people do it with

28
00:01:29,160 --> 00:01:34,680
Speaker 1: with varying degrees of pride or or or disgrace. Well.

29
00:01:34,720 --> 00:01:37,240
Speaker 1: As as I've shared before, I come from a various

30
00:01:37,240 --> 00:01:40,280
Speaker 1: schatological family, so this is a topic that has been

31
00:01:40,280 --> 00:01:43,680
Speaker 1: plumbed in the family. I'm not scared to talk about it.

32
00:01:43,760 --> 00:01:46,280
Speaker 1: And uh, I feel like there's lots of really great

33
00:01:46,319 --> 00:01:50,160
Speaker 1: information here. Uh, in particular this idea of this fire

34
00:01:50,360 --> 00:01:54,960
Speaker 1: breathing dragon. And this is fascinating to me. This was

35
00:01:55,040 --> 00:01:58,520
Speaker 1: in Mary Richard's Gulp. She spoke with herpetologist, Steven s

36
00:01:58,680 --> 00:02:02,560
Speaker 1: cor who became infixated on the question of why a

37
00:02:02,680 --> 00:02:07,080
Speaker 1: python or a boa um has an unusually large see

38
00:02:07,120 --> 00:02:09,639
Speaker 1: some Okay, so I see someone like this little digestive pouch.

39
00:02:09,680 --> 00:02:13,360
Speaker 1: It's near the colon and normally you see implant eating animals,

40
00:02:13,720 --> 00:02:16,239
Speaker 1: and so he became obsessed with why, why which is

41
00:02:16,280 --> 00:02:19,280
Speaker 1: a python have this? So he tried to figure out

42
00:02:19,320 --> 00:02:21,760
Speaker 1: the role of the season, whether or not it was

43
00:02:21,800 --> 00:02:24,200
Speaker 1: just there to break down the plant material in the

44
00:02:24,240 --> 00:02:28,320
Speaker 1: animal that the python had just ingested. Um, And he

45
00:02:28,360 --> 00:02:32,000
Speaker 1: began to actually measure the amount of hydrogen coming out

46
00:02:32,000 --> 00:02:34,639
Speaker 1: of a python, ex like what it was exhaling after

47
00:02:34,720 --> 00:02:38,200
Speaker 1: it was given a bunch of rats to eat. Okay,

48
00:02:38,240 --> 00:02:41,080
Speaker 1: So he did that with something called a chromatograph, and

49
00:02:41,160 --> 00:02:45,040
Speaker 1: that measured the amount of hydrogen alright. What he actually

50
00:02:45,080 --> 00:02:49,080
Speaker 1: found out, though, was that the amount of hydrogen that

51
00:02:49,200 --> 00:02:52,440
Speaker 1: was being exhaled by these creatures was enormous. I think

52
00:02:52,440 --> 00:02:58,359
Speaker 1: about this hydrogen concentration is flammable. These guys and gals

53
00:02:58,560 --> 00:03:02,480
Speaker 1: were exhaling something about Okay, so what does any of

54
00:03:02,600 --> 00:03:06,520
Speaker 1: us have to do with belching or gas or inflate us. Well,

55
00:03:06,600 --> 00:03:10,360
Speaker 1: it turns out Square has this really great theory that

56
00:03:10,919 --> 00:03:15,799
Speaker 1: early man would stumble across, say a python that had

57
00:03:15,960 --> 00:03:19,000
Speaker 1: just or it was in the middle of digesting a gazelle,

58
00:03:19,840 --> 00:03:22,880
Speaker 1: and so, as you know, the python would be useless

59
00:03:22,880 --> 00:03:26,000
Speaker 1: and trying to defend itself. Correct, you just eating this

60
00:03:26,080 --> 00:03:29,919
Speaker 1: huge meal, bloated. It's not gonna amediately run off. I

61
00:03:30,000 --> 00:03:32,040
Speaker 1: never room for another one, right, So early man says,

62
00:03:32,080 --> 00:03:34,839
Speaker 1: a easy food. I've got dinner tonight. I have two

63
00:03:34,840 --> 00:03:37,840
Speaker 1: things for dinner tonight. Right. I think that Mary rich

64
00:03:37,880 --> 00:03:43,160
Speaker 1: had described it as Neanderthal for duncan. Okay, so early

65
00:03:43,200 --> 00:03:46,360
Speaker 1: man or woman hauls us off to a campsite. There's

66
00:03:46,360 --> 00:03:50,520
Speaker 1: a fire, someone is being you know, joyful, and they

67
00:03:50,600 --> 00:03:54,440
Speaker 1: begin to say, step on this python's head or they

68
00:03:54,520 --> 00:03:57,760
Speaker 1: kick it, and what happens. A huge flood of this

69
00:03:57,920 --> 00:04:02,080
Speaker 1: hydrogen just rolls out of the mouth, meets the fire,

70
00:04:02,760 --> 00:04:07,200
Speaker 1: and then and then you have a fire breathing reptile. Yeah,

71
00:04:07,400 --> 00:04:10,040
Speaker 1: so s course says, think about the thousands and thousands

72
00:04:10,040 --> 00:04:12,720
Speaker 1: of years of these tales of bringing down a fire

73
00:04:12,800 --> 00:04:16,280
Speaker 1: breathing giant to your campsite. Because I could see, on

74
00:04:16,279 --> 00:04:18,360
Speaker 1: one hand, someone could be like, whoa, that thing can

75
00:04:18,600 --> 00:04:21,080
Speaker 1: can breathe fire? I was really I was. I was

76
00:04:21,160 --> 00:04:23,760
Speaker 1: really lucky that I didn't get toasted back there, or

77
00:04:24,000 --> 00:04:25,960
Speaker 1: they'd see what happened and they realized, well, this thing

78
00:04:26,000 --> 00:04:28,159
Speaker 1: doesn't actually breathe fire, but it sure did look like it.

79
00:04:28,360 --> 00:04:30,480
Speaker 1: And I'm going to claim that it does because I

80
00:04:30,560 --> 00:04:33,760
Speaker 1: look all the more awesome for having killed it. Slated right,

81
00:04:33,839 --> 00:04:36,440
Speaker 1: and I fast forward, you know, fifty thou years to

82
00:04:37,080 --> 00:04:39,600
Speaker 1: modern humans in eight year olds all around camp fires

83
00:04:39,600 --> 00:04:42,479
Speaker 1: trying to light their farts. Right there. We have a

84
00:04:42,520 --> 00:04:45,719
Speaker 1: long tradition of this relationship with gas and man. Yeah,

85
00:04:45,720 --> 00:04:49,039
Speaker 1: anybody who's read Mary Roaches Packing from Mars book about

86
00:04:49,080 --> 00:04:52,480
Speaker 1: the space program and human space exploration, now, so there's

87
00:04:52,480 --> 00:04:55,200
Speaker 1: a there's a lot of scatological content in here, because

88
00:04:55,240 --> 00:05:00,279
Speaker 1: you're talking about sending humans and their digestive systems into

89
00:05:00,320 --> 00:05:03,160
Speaker 1: a strange environment that doesn't necessarily play by the rules,

90
00:05:03,160 --> 00:05:04,960
Speaker 1: and at the very least is contained within a very

91
00:05:04,960 --> 00:05:08,599
Speaker 1: small space, and inevitably you have astronauts that are going

92
00:05:08,640 --> 00:05:11,400
Speaker 1: to pass gas and uh. I believe it was measured

93
00:05:11,440 --> 00:05:13,240
Speaker 1: out to be like three coke cans worth of worth

94
00:05:13,240 --> 00:05:16,599
Speaker 1: of gas is coming out. So there were a couple

95
00:05:16,640 --> 00:05:21,240
Speaker 1: of interesting bits there involving NASA research. One was a

96
00:05:21,360 --> 00:05:25,239
Speaker 1: quest of by um Edwin Murphy UH in an attempt

97
00:05:25,240 --> 00:05:28,240
Speaker 1: to find though what what the ideal fart profile for

98
00:05:28,279 --> 00:05:32,080
Speaker 1: an astronaut would be um and basically they wanted a

99
00:05:32,080 --> 00:05:34,359
Speaker 1: little or no methane or hydrogen, because, as we just

100
00:05:34,360 --> 00:05:38,920
Speaker 1: touched on, hydrogen is explosive and methane is not desirable either.

101
00:05:39,240 --> 00:05:41,840
Speaker 1: But in his work. This guy Murphy had apparently encountered

102
00:05:41,960 --> 00:05:45,320
Speaker 1: one ideal astronaut candidate, and then this is the quote.

103
00:05:45,360 --> 00:05:47,960
Speaker 1: A special interest for further research was the subject who

104
00:05:48,000 --> 00:05:53,640
Speaker 1: produced essentially no flatus on one grounds dry weight of beans,

105
00:05:54,200 --> 00:05:56,880
Speaker 1: as opposed to the average gut, which will during a

106
00:05:57,000 --> 00:05:59,480
Speaker 1: peak of flash ones period five or six hours post

107
00:05:59,520 --> 00:06:02,640
Speaker 1: being consider umption, pass anywhere from one to almost three

108
00:06:02,640 --> 00:06:07,560
Speaker 1: cups of latest per hour. So, uh, that is particularly interesting.

109
00:06:07,720 --> 00:06:10,480
Speaker 1: Interesting not only because NASA you know, wants that ideal

110
00:06:10,600 --> 00:06:13,599
Speaker 1: fart profile for an astronaut, or or that you know

111
00:06:13,680 --> 00:06:17,160
Speaker 1: you would given the chance, but that there are individuals

112
00:06:17,200 --> 00:06:21,520
Speaker 1: that are almost non farters, which is interesting. It is

113
00:06:21,560 --> 00:06:27,760
Speaker 1: amazing to me because I mean, presumably again everybody does this,

114
00:06:28,320 --> 00:06:30,040
Speaker 1: and I do think it's very kind of NASA, by

115
00:06:30,080 --> 00:06:32,960
Speaker 1: the way, to try to recruit people who don't do

116
00:06:33,000 --> 00:06:36,200
Speaker 1: it so much, because, as we discussed in our Emotions

117
00:06:36,400 --> 00:06:39,800
Speaker 1: in Space episode, can get dicey up there, and if

118
00:06:39,800 --> 00:06:42,479
Speaker 1: you're next to someone who keeps putt putting, you know,

119
00:06:42,600 --> 00:06:46,240
Speaker 1: for six months straight, that that can make things very tense.

120
00:06:46,920 --> 00:06:52,480
Speaker 1: So let's talk about fart. What is it? Well, basically,

121
00:06:52,800 --> 00:06:54,680
Speaker 1: the act of farting, of course, is the means by

122
00:06:54,680 --> 00:06:58,000
Speaker 1: which the body rids the colon of unwanted gas, and

123
00:06:58,160 --> 00:07:00,800
Speaker 1: by virtue of that unwanted pressure, you have this gas

124
00:07:00,839 --> 00:07:04,839
Speaker 1: that builds up and the average person releases between five

125
00:07:05,320 --> 00:07:08,800
Speaker 1: two thousand million liters of this per day. But but yeah,

126
00:07:08,839 --> 00:07:15,760
Speaker 1: what does it consist of? Well, about its carbon dioxide, hydrogen, nitrogen, oxygen,

127
00:07:16,160 --> 00:07:18,680
Speaker 1: and methane and go again, varying degrees of that depending

128
00:07:18,680 --> 00:07:21,520
Speaker 1: on the particular part part because some people don't produce methane.

129
00:07:21,960 --> 00:07:23,840
Speaker 1: I think it's like only one third of us produce

130
00:07:23,920 --> 00:07:27,240
Speaker 1: methane yep. And most of these gases are either swallowed

131
00:07:27,280 --> 00:07:30,560
Speaker 1: inadvertently when you're eating your food or release from the

132
00:07:30,560 --> 00:07:34,840
Speaker 1: food as it is digested. And uh, it's amazing because

133
00:07:35,480 --> 00:07:37,880
Speaker 1: when it's in your body, it is odorless, and we

134
00:07:37,920 --> 00:07:40,080
Speaker 1: don't think of it as being odorless. Right. And the

135
00:07:40,120 --> 00:07:42,760
Speaker 1: other key thing that of the ingredients that are just

136
00:07:42,800 --> 00:07:47,360
Speaker 1: listed that is odorless, all the hydrogen, the methane, oxygen,

137
00:07:47,400 --> 00:07:49,760
Speaker 1: all of it, that is not the odor producing content.

138
00:07:50,280 --> 00:07:53,880
Speaker 1: It is that one percent that is responsible for the smell. Yeah,

139
00:07:53,880 --> 00:07:56,119
Speaker 1: we'll get to that one percent and a bit. Yeah,

140
00:07:56,560 --> 00:07:58,880
Speaker 1: spend such a political term day as one percent. That's

141
00:07:58,920 --> 00:08:00,920
Speaker 1: kind of funny thing one peron that stinking up the

142
00:08:00,920 --> 00:08:05,120
Speaker 1: whole system exactly. Um, So, as you had mentioned, we

143
00:08:05,160 --> 00:08:07,240
Speaker 1: do expel quite a bit of it. But the man

144
00:08:07,320 --> 00:08:11,000
Speaker 1: who inspired really thoughtful study of how much we expel

145
00:08:11,200 --> 00:08:14,400
Speaker 1: and even excessive gas is a man who in nineteen

146
00:08:14,480 --> 00:08:18,720
Speaker 1: six complained of a five year epic bout of the

147
00:08:18,760 --> 00:08:23,160
Speaker 1: twos he UM. He contacted gas from entrologist Michael Levitt,

148
00:08:23,760 --> 00:08:26,120
Speaker 1: and in order to study the man, Lovett had to

149
00:08:26,160 --> 00:08:30,440
Speaker 1: create a baseline of normal flattist output so or flatists,

150
00:08:30,440 --> 00:08:33,840
Speaker 1: I should say. He recruited volunteers to keep flat too,

151
00:08:33,960 --> 00:08:39,440
Speaker 1: graphic lags flogs of gas activity, recording every stirring in

152
00:08:39,520 --> 00:08:43,160
Speaker 1: every output. He prefers that actually, but he did, and

153
00:08:43,200 --> 00:08:47,880
Speaker 1: others have relied on um studies that use a rectal

154
00:08:47,960 --> 00:08:52,040
Speaker 1: tube in collection syringes to determine average output. That is

155
00:08:52,360 --> 00:08:55,080
Speaker 1: year old way of trying to figure out how much

156
00:08:55,400 --> 00:09:02,439
Speaker 1: people are expelling. So basically the farting jar scenario, Yeah,

157
00:09:02,520 --> 00:09:05,560
Speaker 1: but a little bit more foolproof and a lot more

158
00:09:05,640 --> 00:09:08,000
Speaker 1: going on. And the syringes there just to extract the

159
00:09:08,040 --> 00:09:10,520
Speaker 1: molecules and then to to figure out what sort of

160
00:09:10,559 --> 00:09:15,360
Speaker 1: molecules are in there. Um, these days. Hydrogen output is

161
00:09:15,400 --> 00:09:18,640
Speaker 1: measured in the breath because a fixed percentage of hydrogen

162
00:09:18,679 --> 00:09:21,520
Speaker 1: produced in the colon is absorbed into the blood and

163
00:09:21,880 --> 00:09:25,840
Speaker 1: when it reaches the lungs, it's exhaled. Now, what he

164
00:09:25,960 --> 00:09:28,800
Speaker 1: found was that this man was passing gas thirty four

165
00:09:28,840 --> 00:09:31,920
Speaker 1: to forty two times a day. Okay, the baseline average

166
00:09:31,960 --> 00:09:36,640
Speaker 1: here of the humans who doesn't have any lactose intolerance

167
00:09:36,640 --> 00:09:40,120
Speaker 1: problems is about fourteen to twenty times a day in

168
00:09:40,160 --> 00:09:43,839
Speaker 1: case you're wondering. So the problem that they finally figured

169
00:09:43,880 --> 00:09:46,320
Speaker 1: out is that he was lactose intolerant, and as we

170
00:09:46,400 --> 00:09:50,200
Speaker 1: learned before, lactose does not get broken down for some

171
00:09:50,280 --> 00:09:53,080
Speaker 1: people in the digestive excuse me, in the small intestines

172
00:09:53,520 --> 00:09:57,120
Speaker 1: hangs out in the colon, and then you have other

173
00:09:57,160 --> 00:09:59,559
Speaker 1: bacteria which we're breaking that down, and then you've got

174
00:09:59,559 --> 00:10:01,240
Speaker 1: the waste p act of that bacteria, and you've got

175
00:10:01,280 --> 00:10:04,480
Speaker 1: a bunch of bunch of bunch of hydrogen being produced there. Yes,

176
00:10:05,120 --> 00:10:07,720
Speaker 1: of course, we're talking about humans as a whole in

177
00:10:07,720 --> 00:10:12,080
Speaker 1: regards to UH to flate us. But you can't help

178
00:10:12,120 --> 00:10:14,600
Speaker 1: but get into gender scenarios when you start thinking about

179
00:10:14,679 --> 00:10:16,280
Speaker 1: In fact, one of the articles that we were looking

180
00:10:16,320 --> 00:10:19,240
Speaker 1: at um. Uh they are. The author made a point

181
00:10:19,320 --> 00:10:21,840
Speaker 1: of of saying that men as as a whole, and

182
00:10:21,880 --> 00:10:24,559
Speaker 1: she's really generalizing here and painting with a very broad brush,

183
00:10:25,080 --> 00:10:27,440
Speaker 1: and I skilled her for it. U that all men

184
00:10:27,920 --> 00:10:31,160
Speaker 1: are just enthusiastic about their gas and just love it

185
00:10:31,200 --> 00:10:34,840
Speaker 1: and crave it and laugh at it all the time, yeah,

186
00:10:34,880 --> 00:10:37,800
Speaker 1: and model it. Really, I am not one of those men.

187
00:10:37,880 --> 00:10:41,360
Speaker 1: Like maybe that is the more baseline m relationship between

188
00:10:41,360 --> 00:10:44,160
Speaker 1: men and fart, but I, for my own self, I

189
00:10:44,800 --> 00:10:47,720
Speaker 1: don't engage that style of humor. For the most part,

190
00:10:47,760 --> 00:10:49,839
Speaker 1: I will laugh at a fart joke if it is

191
00:10:49,880 --> 00:10:54,520
Speaker 1: well crafted um or in some way, you know, insightful. Um.

192
00:10:54,679 --> 00:10:57,880
Speaker 1: There have been occasionally they'll get me, like the instance,

193
00:10:57,920 --> 00:11:00,280
Speaker 1: there was a Sarah Silverman Show episode that was very

194
00:11:00,320 --> 00:11:03,880
Speaker 1: far heavy. She's she likes the farts. Yeah, and occasionally

195
00:11:04,160 --> 00:11:06,360
Speaker 1: that will work. I mean, it's it's the right fartship.

196
00:11:06,440 --> 00:11:08,720
Speaker 1: But as a whole, I do not. I'm more of

197
00:11:09,080 --> 00:11:11,360
Speaker 1: a stereotypical if you're gonna go with these stereotypes, I'm

198
00:11:11,360 --> 00:11:14,800
Speaker 1: more of a stereotypical woman when it comes to fart

199
00:11:14,840 --> 00:11:19,240
Speaker 1: gags and self gas production than a stereotypical man. Okay,

200
00:11:19,240 --> 00:11:20,960
Speaker 1: So what I'm hearing is that you don't have a

201
00:11:21,000 --> 00:11:25,480
Speaker 1: cellar full of arrears. No I do not. Okay, all right,

202
00:11:25,480 --> 00:11:27,880
Speaker 1: this is good, um. And it's interesting that you bring

203
00:11:27,880 --> 00:11:30,559
Speaker 1: out the stereotypes because you know, if it's were the

204
00:11:30,640 --> 00:11:33,000
Speaker 1: Victorian age, we would say, oh, well, women just don't

205
00:11:33,000 --> 00:11:36,840
Speaker 1: produce gas at all, right, it wouldn't even be a question.

206
00:11:37,040 --> 00:11:39,280
Speaker 1: But we do have data on it, and it turns

207
00:11:39,320 --> 00:11:43,760
Speaker 1: out that women have are seemed to be expelling more

208
00:11:43,800 --> 00:11:49,440
Speaker 1: gas than men, as measured by the hydrogen exhaled. But

209
00:11:49,800 --> 00:11:53,839
Speaker 1: Mary Roach questions this and says in her book, could

210
00:11:53,880 --> 00:11:57,960
Speaker 1: it be that the suppression of gas could lead to

211
00:11:58,160 --> 00:12:03,280
Speaker 1: a higher input of hydrogen exhalation? So maybe if you're

212
00:12:03,280 --> 00:12:05,839
Speaker 1: going with the stereotypical um I almos don't want to

213
00:12:05,840 --> 00:12:08,160
Speaker 1: say stereotypical female, but let's say, let's go with you.

214
00:12:08,160 --> 00:12:12,840
Speaker 1: If you're going with a fart avoidant person like myself,

215
00:12:13,360 --> 00:12:15,679
Speaker 1: then they are going to be less inclined to just

216
00:12:15,800 --> 00:12:18,080
Speaker 1: let it rip whenever the mood hits them. Right, So

217
00:12:18,120 --> 00:12:20,480
Speaker 1: if you suppress it, then you're going to absorb more

218
00:12:20,480 --> 00:12:23,040
Speaker 1: of it through your bloodstream and then you're going to

219
00:12:23,080 --> 00:12:26,199
Speaker 1: exhale mark. Oh, so the way, you're kind of reversing

220
00:12:26,200 --> 00:12:29,880
Speaker 1: it and farting into your body, into your blood. You're

221
00:12:29,920 --> 00:12:32,920
Speaker 1: just breath farting, okay, right, and that makes it really

222
00:12:32,920 --> 00:12:35,800
Speaker 1: a lovely thought, doesn't it. Do I think about that

223
00:12:35,840 --> 00:12:39,920
Speaker 1: next time you give your significant other nice little kiss? Yeah,

224
00:12:40,360 --> 00:12:42,280
Speaker 1: you know, I I do. I should. At one point

225
00:12:42,320 --> 00:12:44,840
Speaker 1: about about ladies and farting. I did work in a

226
00:12:44,840 --> 00:12:48,280
Speaker 1: newspaper once and an individual in the front office was

227
00:12:48,480 --> 00:12:52,080
Speaker 1: terminated for engaging in a farting contest with a with

228
00:12:51,720 --> 00:12:56,560
Speaker 1: a with a customer. It was it was quite it. It

229
00:12:56,480 --> 00:12:58,880
Speaker 1: It seems like it was mutual farting, so I guess

230
00:12:58,920 --> 00:13:00,800
Speaker 1: it was just like, hey, this is we're going to

231
00:13:00,880 --> 00:13:03,880
Speaker 1: make an example of you. We just fart with the customer. Maybe,

232
00:13:03,880 --> 00:13:05,600
Speaker 1: you know, there could have been some other politics involved,

233
00:13:05,679 --> 00:13:07,240
Speaker 1: or maybe it was just kind of this unwritten rule

234
00:13:07,320 --> 00:13:10,480
Speaker 1: where if your customer comes in and celebrates his or

235
00:13:10,520 --> 00:13:13,760
Speaker 1: her farts, that's fine, but then you are not supposed

236
00:13:13,800 --> 00:13:17,120
Speaker 1: to then engage with them in a contest of farts

237
00:13:17,360 --> 00:13:19,880
Speaker 1: or you know, it's it's kind of like it's it's okay,

238
00:13:20,000 --> 00:13:23,280
Speaker 1: the customer uses foul language to a point, but you're

239
00:13:23,280 --> 00:13:25,079
Speaker 1: in then not supposed to engage them in that kind

240
00:13:25,080 --> 00:13:28,280
Speaker 1: of behavior, I guess. Or maybe maybe she showed him up,

241
00:13:28,280 --> 00:13:31,120
Speaker 1: maybe she shamed him and they lost the customer because

242
00:13:31,240 --> 00:13:34,240
Speaker 1: it was this a gastrontrology office. No, this was a

243
00:13:34,240 --> 00:13:38,880
Speaker 1: newspaper with we didn't even have a flatest section, you know,

244
00:13:39,080 --> 00:13:42,480
Speaker 1: just business and sports. Yeah. Yeah, I don't know that

245
00:13:42,480 --> 00:13:43,960
Speaker 1: I can recover from that store. I feel like I

246
00:13:44,000 --> 00:13:46,199
Speaker 1: need time to think about that and chuckle. But we

247
00:13:46,280 --> 00:13:49,480
Speaker 1: must go on, so I'm just gonna chuckle about that later. Um.

248
00:13:49,520 --> 00:13:53,800
Speaker 1: All right, so let's talk about this one. Yes, or

249
00:13:53,840 --> 00:13:56,880
Speaker 1: should we take a break? Oh? Yeah, let's take a break.

250
00:13:56,880 --> 00:13:58,800
Speaker 1: Why not? When we come back, we will discuss the

251
00:13:58,880 --> 00:14:01,960
Speaker 1: one percent of the fart it is responsible for the smell.

252
00:14:02,640 --> 00:14:06,000
Speaker 1: We'll talk about extraordinary cases of flateust. We'll talk about

253
00:14:06,400 --> 00:14:10,800
Speaker 1: people who have elevated um passing gas to an art form.

254
00:14:10,880 --> 00:14:14,679
Speaker 1: And also the big question, if you're in microgravity, can

255
00:14:14,760 --> 00:14:18,600
Speaker 1: you propel yourself across a spaceship just by virtue of

256
00:14:18,640 --> 00:14:31,160
Speaker 1: your own uh slatest? All right, we're back. So as

257
00:14:31,160 --> 00:14:36,640
Speaker 1: we've discussed of flateut is, carbon dioxide, hydrogen, nitrogen, oxygen,

258
00:14:36,680 --> 00:14:39,880
Speaker 1: and methane, and uh these are coming from stuff that

259
00:14:40,320 --> 00:14:42,760
Speaker 1: either gases that are inadvertently swallowed or it is released

260
00:14:42,760 --> 00:14:44,960
Speaker 1: from the food is we're digesting it. But none of

261
00:14:45,000 --> 00:14:49,360
Speaker 1: it produces the signature odors and it varies certainly, as

262
00:14:49,360 --> 00:14:52,640
Speaker 1: we can all attest to. Uh. None of these elements

263
00:14:52,720 --> 00:14:55,760
Speaker 1: contribute to the odor. Is just of tiny one that

264
00:14:56,080 --> 00:14:59,280
Speaker 1: makes the gas so foul, that's right, that creates that

265
00:14:59,400 --> 00:15:04,320
Speaker 1: singular a bouquet of smell. Micro Has really live for

266
00:15:04,320 --> 00:15:06,560
Speaker 1: the most part in the colon where they attack and

267
00:15:06,640 --> 00:15:11,680
Speaker 1: consume undigested food and in turn generate their own waste products.

268
00:15:11,800 --> 00:15:15,240
Speaker 1: So in the case of microorganisms, waste usually means gas,

269
00:15:15,280 --> 00:15:18,760
Speaker 1: and in the case of these microorganism organisms, that gas

270
00:15:18,760 --> 00:15:22,880
Speaker 1: can be the really ripe stuff, usually molecules containing sulfur

271
00:15:23,520 --> 00:15:29,560
Speaker 1: like dimethyl sulfide and method methyl um. These are waste

272
00:15:29,560 --> 00:15:32,600
Speaker 1: products that ferment and they build up to a sufficient

273
00:15:32,680 --> 00:15:34,560
Speaker 1: level and then they're released with the rest of the

274
00:15:34,600 --> 00:15:37,040
Speaker 1: gas in the bowels. And by the way, we talked

275
00:15:37,040 --> 00:15:40,320
Speaker 1: about this before, the birth of the fart happens when uh,

276
00:15:40,400 --> 00:15:44,920
Speaker 1: you're stretch receptors um in your colon send a signal

277
00:15:44,960 --> 00:15:48,000
Speaker 1: to your brain, Hey, I'm having some discomfort, and then

278
00:15:48,120 --> 00:15:51,640
Speaker 1: this finkter is loosened up, and and then the message

279
00:15:51,640 --> 00:15:54,960
Speaker 1: maybe when you get a chance, please do something about this,

280
00:15:55,200 --> 00:15:58,040
Speaker 1: or maybe this is really important. So the next time

281
00:15:58,520 --> 00:16:00,840
Speaker 1: you even have like a heavy thought in the back

282
00:16:00,840 --> 00:16:02,840
Speaker 1: of your head, um, we're going to just go ahead

283
00:16:02,840 --> 00:16:06,480
Speaker 1: and let it go even have you Yeah, yeah, that's right.

284
00:16:06,480 --> 00:16:08,640
Speaker 1: The brain will sit there and respond and say, okay,

285
00:16:08,760 --> 00:16:11,720
Speaker 1: now you gotta tampa down, sorry, swincter, or yep, we're

286
00:16:11,760 --> 00:16:17,520
Speaker 1: overloaded here alright. So what brave soul figured out the

287
00:16:17,560 --> 00:16:22,000
Speaker 1: scent profile of late us. Well, the same Michael Levitt

288
00:16:22,040 --> 00:16:25,320
Speaker 1: who helped to determine the output of late US also

289
00:16:25,600 --> 00:16:29,880
Speaker 1: studies the qualities of of gas. These smell profiles, he

290
00:16:29,960 --> 00:16:34,240
Speaker 1: recruited volunteers to detect the three main elements of a

291
00:16:34,360 --> 00:16:38,040
Speaker 1: fart so hydrogen sulfide which is described as the scent

292
00:16:38,120 --> 00:16:43,240
Speaker 1: of rotten eggs uh metha nephiel that is described as

293
00:16:43,520 --> 00:16:48,080
Speaker 1: rotting vegetation, and dimethyl sulfide, which is oddly described as

294
00:16:48,080 --> 00:16:51,920
Speaker 1: sweet m Yes. So he didn't do this as a

295
00:16:52,040 --> 00:16:55,120
Speaker 1: cruel joke. I mean, he wasn't just trying to you know,

296
00:16:55,560 --> 00:16:58,720
Speaker 1: terrorize people with smells. He wanted to see if the

297
00:16:58,840 --> 00:17:02,840
Speaker 1: noxiousness of the scent would correlate with the combined concentrations

298
00:17:02,920 --> 00:17:06,840
Speaker 1: of these three types of sulfur gases, and it did. So.

299
00:17:07,960 --> 00:17:09,960
Speaker 1: The best part of this, all this information is he

300
00:17:10,000 --> 00:17:14,160
Speaker 1: took the data and he reversed engineer to fart so

301
00:17:14,359 --> 00:17:18,840
Speaker 1: he could use the combined concentrations in other scenarios. Would

302
00:17:18,880 --> 00:17:21,960
Speaker 1: would it be safe to call this a frank and fart, Yes,

303
00:17:22,080 --> 00:17:24,640
Speaker 1: it would be absolutely Um it's a frank and part.

304
00:17:24,720 --> 00:17:28,520
Speaker 1: And he wanted to figure out the absorptive properties of

305
00:17:28,600 --> 00:17:32,080
Speaker 1: charcoal underpants or seat pads, which, by the way, is

306
00:17:32,320 --> 00:17:36,520
Speaker 1: of interest to the airline industry. Which makes sense, right,

307
00:17:36,560 --> 00:17:39,560
Speaker 1: I think that I said, go airline industry, put charcoal

308
00:17:39,600 --> 00:17:42,840
Speaker 1: in the seat pads. Any degree to which you can

309
00:17:43,080 --> 00:17:45,679
Speaker 1: cut down on the on the amount of flatus in

310
00:17:45,680 --> 00:17:48,840
Speaker 1: that enclosed space on a long flight, the better, Yeah, exactly.

311
00:17:48,880 --> 00:17:52,200
Speaker 1: In speaking of a long flight or a spacewalk, NASA

312
00:17:52,240 --> 00:17:56,120
Speaker 1: actually has used filters in the air circulation in space

313
00:17:56,160 --> 00:18:01,320
Speaker 1: suits with charcoal to help bind sulfur and then prevent

314
00:18:01,400 --> 00:18:03,800
Speaker 1: the astronauts from getting drive by farted every time the

315
00:18:03,840 --> 00:18:06,400
Speaker 1: air is recirculated. Yeah, because if they build up enough

316
00:18:06,440 --> 00:18:10,200
Speaker 1: along enough space walk, then fart madness ensues. I've heard

317
00:18:10,200 --> 00:18:12,600
Speaker 1: about madness. It isn't earth. There are a lot of

318
00:18:14,000 --> 00:18:16,240
Speaker 1: I was looking on snopes to see if there were

319
00:18:16,280 --> 00:18:20,040
Speaker 1: any particular urban legends related to the farting of note,

320
00:18:20,160 --> 00:18:23,240
Speaker 1: and one of them was this bit that occasionally circulates

321
00:18:23,240 --> 00:18:26,040
Speaker 1: and emails about a man who who died because he

322
00:18:26,160 --> 00:18:29,119
Speaker 1: farted under the covers and uh and had the covers

323
00:18:29,160 --> 00:18:32,560
Speaker 1: up over his head. But that's just complete malarkey. That's

324
00:18:32,600 --> 00:18:35,640
Speaker 1: just a Dutch Oven. Yeah, so so yeah, so death

325
00:18:35,720 --> 00:18:39,240
Speaker 1: by by death by by Dutch Oven not really a thing. Yeah,

326
00:18:39,280 --> 00:18:41,520
Speaker 1: And you can't try to, I mean, just for fun

327
00:18:41,680 --> 00:18:45,119
Speaker 1: Dutch Oven astronauts, right, No, No, I mean they'd go

328
00:18:45,200 --> 00:18:47,000
Speaker 1: through enough in the training. I'm sure they were, like,

329
00:18:47,240 --> 00:18:49,760
Speaker 1: you know, after you've been in that spinny thing long enough,

330
00:18:49,800 --> 00:18:52,119
Speaker 1: and I mean we've all seen the right stuff. They

331
00:18:52,200 --> 00:18:55,760
Speaker 1: went through a lot of horrible things to prove themselves

332
00:18:55,760 --> 00:18:57,720
Speaker 1: and and to you know, to get their bodies in

333
00:18:57,720 --> 00:19:00,440
Speaker 1: shape and prepare themselves for this this experience in orbit.

334
00:19:00,480 --> 00:19:02,400
Speaker 1: So and keep in mind that the air in their

335
00:19:02,400 --> 00:19:05,520
Speaker 1: space suits is actually recirculated three times a minute. So

336
00:19:06,600 --> 00:19:10,639
Speaker 1: now another interesting bit from Mary Roch's book, Packing for Mars.

337
00:19:10,680 --> 00:19:13,040
Speaker 1: She talked to an astronaut by the name of Roger Crouch,

338
00:19:13,600 --> 00:19:17,040
Speaker 1: and he was particularly interested in the idea of propelling

339
00:19:17,080 --> 00:19:20,639
Speaker 1: yourself through a microgravity environment like a board the space

340
00:19:20,680 --> 00:19:25,400
Speaker 1: station via your own farts. And he said that the

341
00:19:25,480 --> 00:19:28,080
Speaker 1: math and velocity of the expelled gas is very small

342
00:19:28,119 --> 00:19:30,320
Speaker 1: compared to the mass of the human body. So he

343
00:19:30,359 --> 00:19:33,199
Speaker 1: tested it out found that it produced no real effect,

344
00:19:33,440 --> 00:19:36,159
Speaker 1: though he did, uh, he did have this theory that

345
00:19:36,280 --> 00:19:40,640
Speaker 1: the underpants and the pants might be prohibiting the expulsion

346
00:19:40,640 --> 00:19:42,840
Speaker 1: of gas, and so he but he did not get

347
00:19:42,880 --> 00:19:47,120
Speaker 1: to test this naked, but he apparently has lingering thoughts

348
00:19:47,160 --> 00:19:52,480
Speaker 1: that that nude farting in microgravity would potentially give you

349
00:19:52,520 --> 00:19:54,600
Speaker 1: at least a little push across the cabin. Yeah, that

350
00:19:54,720 --> 00:19:57,240
Speaker 1: really is not going to win the hearts and minds

351
00:19:57,240 --> 00:20:01,120
Speaker 1: of your fellow astronauts and face if you just drop

352
00:20:01,200 --> 00:20:04,399
Speaker 1: trial and then try to propel yourself with your own parts.

353
00:20:04,520 --> 00:20:06,359
Speaker 1: Can you imagine the dude's doing like the crying in

354
00:20:06,400 --> 00:20:10,560
Speaker 1: space videos and all the different viral videos of Colonel Hatfield. Yeah,

355
00:20:10,640 --> 00:20:13,000
Speaker 1: I wonder, I wonder if he's on board for this.

356
00:20:13,600 --> 00:20:15,560
Speaker 1: That's going to be a big shock when that when

357
00:20:15,560 --> 00:20:18,000
Speaker 1: that YouTube video rolls out that might be the one

358
00:20:18,040 --> 00:20:21,240
Speaker 1: that never really makes it too right. So though, if

359
00:20:21,280 --> 00:20:24,240
Speaker 1: you were going to do that experiment without underpants and

360
00:20:24,400 --> 00:20:26,680
Speaker 1: really truly test it, you would want to eat the

361
00:20:26,880 --> 00:20:31,440
Speaker 1: gasest inducing foods that you could. And it turns out

362
00:20:31,520 --> 00:20:36,480
Speaker 1: that the most eruptive edibles are beans, carrots, raisins, bananas,

363
00:20:36,800 --> 00:20:40,159
Speaker 1: which is odd to me. Onions not odd milk and

364
00:20:40,200 --> 00:20:43,240
Speaker 1: milk products for the very reasons that we talked before

365
00:20:43,280 --> 00:20:46,640
Speaker 1: about milk being hard to digest and break down as

366
00:20:46,640 --> 00:20:52,920
Speaker 1: opposed to something like um, let's say meat, fish, grapes, berries,

367
00:20:53,280 --> 00:20:56,280
Speaker 1: these are these have the least amount of complex carbohydrates.

368
00:20:56,720 --> 00:21:01,360
Speaker 1: It's it's this, uh, this really damning conundrum that that

369
00:21:01,400 --> 00:21:03,280
Speaker 1: I that I have encountered, and then I think a

370
00:21:03,320 --> 00:21:05,960
Speaker 1: number of people encountered that the healthier that you try

371
00:21:05,960 --> 00:21:07,640
Speaker 1: to eat, you know, you're trying, you're trying to eat

372
00:21:07,640 --> 00:21:12,040
Speaker 1: all these vegetables and these whole grains and lintels and beans,

373
00:21:12,160 --> 00:21:14,560
Speaker 1: and it's just it's making you're gassier, and you feel

374
00:21:14,560 --> 00:21:17,879
Speaker 1: like you're being punished for this diet. Uh. Dr Robert

375
00:21:17,960 --> 00:21:20,200
Speaker 1: Lustig even put it this way. He said, in life,

376
00:21:20,200 --> 00:21:26,160
Speaker 1: you have two choices. It's either fat or fart. So yeah,

377
00:21:26,280 --> 00:21:28,960
Speaker 1: it's true, like if you were to radically change your

378
00:21:28,960 --> 00:21:32,760
Speaker 1: diet from say a meat and very little um vegetable

379
00:21:33,200 --> 00:21:36,840
Speaker 1: diet to grains and vegetables, you would really need to

380
00:21:36,880 --> 00:21:39,240
Speaker 1: set aside a couple of days to transition into that.

381
00:21:40,320 --> 00:21:43,480
Speaker 1: Kid you not, Well, there's that great Portlandia sketch where

382
00:21:43,480 --> 00:21:45,720
Speaker 1: they go to the restaurant that has the raw food.

383
00:21:45,760 --> 00:21:47,560
Speaker 1: It's like an all raw food places may actually have

384
00:21:47,600 --> 00:21:52,680
Speaker 1: a a flateist patio with fans the fat patio. That

385
00:21:52,840 --> 00:21:55,240
Speaker 1: is just one of my favorite things, one of those

386
00:21:55,280 --> 00:21:58,440
Speaker 1: that that clip is just great because it's not hearty

387
00:21:58,480 --> 00:22:01,119
Speaker 1: horror laugh laugh, but it kind of speaks to that

388
00:22:01,200 --> 00:22:03,560
Speaker 1: whole experience when you do go to a rough foods

389
00:22:03,600 --> 00:22:08,000
Speaker 1: restaurant or a vegan restaurant and the result of that afterwards,

390
00:22:08,000 --> 00:22:10,200
Speaker 1: they just kind of brought it more to the forefront. Yeah,

391
00:22:10,200 --> 00:22:12,439
Speaker 1: it's it's a clever it's a clever bit of of

392
00:22:12,520 --> 00:22:15,680
Speaker 1: parody there and uh and and commentary. So that's that

393
00:22:16,040 --> 00:22:19,280
Speaker 1: is a fart gag that I at least chuckle that sure,

394
00:22:19,320 --> 00:22:21,240
Speaker 1: because really, when you get down to it, every restaurant

395
00:22:21,240 --> 00:22:25,320
Speaker 1: should have a fart patio. Now, as we mentioned before,

396
00:22:25,359 --> 00:22:28,280
Speaker 1: you you have a very rare individual like the individual

397
00:22:28,359 --> 00:22:32,159
Speaker 1: that NASA uncovered who barely farted at all. Just the

398
00:22:32,160 --> 00:22:35,040
Speaker 1: one person in the world, the one person that's a

399
00:22:35,119 --> 00:22:38,480
Speaker 1: mutant that that barely produces any flatus. But then there

400
00:22:38,560 --> 00:22:41,080
Speaker 1: is there's another side of that coin as well. There

401
00:22:41,119 --> 00:22:46,000
Speaker 1: this the super fartre's the the extraordinary flat went individuals

402
00:22:46,040 --> 00:22:49,439
Speaker 1: that that make life so interesting. They just thought that

403
00:22:49,520 --> 00:22:53,120
Speaker 1: some people have types of bacteria that produce more sulfur

404
00:22:53,280 --> 00:22:55,320
Speaker 1: than other people, so that could be part of it.

405
00:22:55,440 --> 00:22:58,000
Speaker 1: Diet is certainly part of it. And then of course,

406
00:22:58,040 --> 00:22:59,720
Speaker 1: as we mentioned earlier, some people are gonna have different

407
00:22:59,720 --> 00:23:01,840
Speaker 1: coins of ptations of hydrogen methane, so some people are

408
00:23:01,840 --> 00:23:04,680
Speaker 1: going to be more explosive, which is UH. And I

409
00:23:04,720 --> 00:23:07,720
Speaker 1: feel like we've discussed this before, but it's it's more

410
00:23:08,119 --> 00:23:11,320
Speaker 1: of a serious issue when there's some sort of surgical

411
00:23:11,359 --> 00:23:15,280
Speaker 1: recedure going on, you know, with the colon UH in

412
00:23:15,320 --> 00:23:17,840
Speaker 1: which you're going to have to cauterize wounds with a

413
00:23:17,880 --> 00:23:22,119
Speaker 1: heat element. That heat element plus hydrogen methane that's built

414
00:23:22,160 --> 00:23:25,560
Speaker 1: up that can have literally an explosive reaction, which is

415
00:23:25,560 --> 00:23:28,000
Speaker 1: not good for anybody involved in that procedure. Now, I

416
00:23:28,000 --> 00:23:30,920
Speaker 1: believe there's an Ignoble prize that was given out this right,

417
00:23:31,240 --> 00:23:33,919
Speaker 1: that's where we discussed it before. But we normally we

418
00:23:33,960 --> 00:23:37,000
Speaker 1: say it's just it's really very funny stuff, but this

419
00:23:37,119 --> 00:23:40,320
Speaker 1: one um study was very serious because it was like,

420
00:23:40,320 --> 00:23:42,120
Speaker 1: you know, what if if you are doing this procedure

421
00:23:42,119 --> 00:23:43,640
Speaker 1: on someone, if someone has a pole up and you're

422
00:23:43,720 --> 00:23:47,360
Speaker 1: moving it, Uh, you don't want them to explode and die. Right,

423
00:23:47,760 --> 00:23:50,520
Speaker 1: So that's that's one of the things that doctors have

424
00:23:50,640 --> 00:23:54,520
Speaker 1: been really cognizant of, and these days they actually pipe

425
00:23:54,520 --> 00:23:57,640
Speaker 1: in a little air um and air that doesn't have

426
00:23:58,240 --> 00:24:01,840
Speaker 1: flammable carbon dioxide as well to try to dilute any

427
00:24:01,920 --> 00:24:05,560
Speaker 1: methane or hydrogen that might be left over. Although for

428
00:24:05,640 --> 00:24:08,320
Speaker 1: anybody who's going to the guests for entrologists and and

429
00:24:08,400 --> 00:24:11,840
Speaker 1: had one of these procedures like a colonoscopy, then you

430
00:24:11,920 --> 00:24:13,960
Speaker 1: know that there's a lot of prep work ahead of

431
00:24:14,000 --> 00:24:18,040
Speaker 1: time to try to remove anything that might antagonize or

432
00:24:18,080 --> 00:24:22,919
Speaker 1: create a spark in your rectum. Another aspect of flate

433
00:24:23,040 --> 00:24:25,800
Speaker 1: us in in the medical community is that it can

434
00:24:25,840 --> 00:24:29,920
Speaker 1: actually be used as a disease fighter sort of. I

435
00:24:29,920 --> 00:24:32,160
Speaker 1: mean it's more like a canary in the coal mine.

436
00:24:32,640 --> 00:24:37,399
Speaker 1: So doctors can actually identify tough to spot viral or

437
00:24:37,520 --> 00:24:41,879
Speaker 1: bacterial infections of the gut in someone's gas. So what

438
00:24:41,960 --> 00:24:44,119
Speaker 1: they do is they just perform this test where they

439
00:24:44,119 --> 00:24:46,680
Speaker 1: collect a stool sample and then they try to take

440
00:24:46,720 --> 00:24:49,560
Speaker 1: the gases um and they extract those gases from a

441
00:24:49,560 --> 00:24:52,119
Speaker 1: smart needle and then they figure out the plate us

442
00:24:52,200 --> 00:24:56,240
Speaker 1: molecules and the machine then will analyze these molecules and

443
00:24:56,320 --> 00:24:59,520
Speaker 1: tell you what the infection. Is. Pretty cool. That is

444
00:24:59,520 --> 00:25:05,520
Speaker 1: pretty cool. Discussing the various smell profiles of human flateust

445
00:25:05,920 --> 00:25:09,879
Speaker 1: UH and ultimately human waste, I keep coming back to

446
00:25:10,680 --> 00:25:16,000
Speaker 1: horse excrement because really, if you've smelled horse excrement, it's

447
00:25:16,040 --> 00:25:19,239
Speaker 1: really the best excrement out there. You know, like if

448
00:25:19,480 --> 00:25:22,120
Speaker 1: you had to be around a bunch of poop all day,

449
00:25:22,840 --> 00:25:25,639
Speaker 1: it's really hard to go wrong with horse. Yeah, Or

450
00:25:25,640 --> 00:25:27,280
Speaker 1: you used to used to work at a zoo, so

451
00:25:27,359 --> 00:25:29,920
Speaker 1: you know that there are various odors related to different

452
00:25:30,200 --> 00:25:33,359
Speaker 1: different animals leavings, and some of them were more pleasant

453
00:25:33,359 --> 00:25:36,000
Speaker 1: than others. Well, yeah, it was funny because I worked

454
00:25:36,000 --> 00:25:38,760
Speaker 1: in the administrative building, but the keepers would come in

455
00:25:39,000 --> 00:25:42,199
Speaker 1: and they had all sorts of smell molecules stuck to

456
00:25:42,240 --> 00:25:44,760
Speaker 1: their bodies. So they might have been working with the

457
00:25:44,840 --> 00:25:47,119
Speaker 1: zeebers that day, who knows, but they passed by the

458
00:25:47,160 --> 00:25:49,359
Speaker 1: elephants and that took it all down. Yeah. So the

459
00:25:49,359 --> 00:25:52,640
Speaker 1: elephants not a good smell profile, okay, but the horse,

460
00:25:52,680 --> 00:25:55,200
Speaker 1: I the horse, I think is a good good smell profile.

461
00:25:56,200 --> 00:26:00,320
Speaker 1: So what do you think about the latest artist? Ah? Yes,

462
00:26:00,760 --> 00:26:03,840
Speaker 1: do you think they're even concerned with a center profile? Well,

463
00:26:03,880 --> 00:26:07,040
Speaker 1: it's it's interesting because first of all, I should I

464
00:26:07,040 --> 00:26:08,720
Speaker 1: should back up and say that I was not aware

465
00:26:08,760 --> 00:26:13,719
Speaker 1: of this until about a year ago. I was recovering

466
00:26:13,800 --> 00:26:16,520
Speaker 1: from Wisdom Tooth Removal, and I was I was on

467
00:26:16,600 --> 00:26:19,280
Speaker 1: pain pills and I was taking I was reading the

468
00:26:19,280 --> 00:26:23,880
Speaker 1: book Madeline is Sweeping by Sarah Shoon Leen Binnum, which

469
00:26:24,040 --> 00:26:27,240
Speaker 1: is a very dreamy book. Anyway, it's like a dream

470
00:26:27,280 --> 00:26:29,560
Speaker 1: within a dream with all this surreal stuff happening. And

471
00:26:29,560 --> 00:26:31,639
Speaker 1: then on top of that, I was a little loopy

472
00:26:31,880 --> 00:26:34,439
Speaker 1: um from everything else that was going on. But one

473
00:26:34,480 --> 00:26:37,119
Speaker 1: of the characters that shows up is a fart artist

474
00:26:37,720 --> 00:26:42,800
Speaker 1: or a fartist if you will, or a flatist or

475
00:26:42,840 --> 00:26:46,320
Speaker 1: a flatuist, but not a flattist, not a flautist. That's uh,

476
00:26:46,400 --> 00:26:50,000
Speaker 1: that's something that's something different entirely. But it turns out

477
00:26:50,000 --> 00:26:52,359
Speaker 1: there's one individual that was a particular note, and it

478
00:26:52,400 --> 00:26:55,399
Speaker 1: was This was a Frenchman whose real name was Joseph

479
00:26:55,440 --> 00:26:59,159
Speaker 1: pugel Uh lived eighteen fifty seven to five, but his

480
00:26:59,200 --> 00:27:03,280
Speaker 1: stage name was Lipped Up the Maine Uh, and he

481
00:27:03,920 --> 00:27:08,000
Speaker 1: was known for having remarkable control over his abdominal muscles,

482
00:27:08,040 --> 00:27:10,360
Speaker 1: and he seemed to be able to just fart at will,

483
00:27:10,480 --> 00:27:14,639
Speaker 1: just NonStop, just well beyond the three coke cans of

484
00:27:14,800 --> 00:27:19,240
Speaker 1: flatists that any normal individual could could muster. But there

485
00:27:19,320 --> 00:27:23,200
Speaker 1: was a secret to what he could actually do. Um.

486
00:27:23,280 --> 00:27:29,120
Speaker 1: He he had again phenomenal control over the muscles down there,

487
00:27:29,160 --> 00:27:33,560
Speaker 1: particularly the anal sphincter muscles, and he could actually inhale

488
00:27:33,680 --> 00:27:37,800
Speaker 1: air through the sphincter and then release it. So he

489
00:27:38,040 --> 00:27:40,240
Speaker 1: wasn't that he was releasing gas that was built up

490
00:27:40,280 --> 00:27:43,640
Speaker 1: as part of this natural farting process that we've discussed

491
00:27:43,640 --> 00:27:47,439
Speaker 1: in this episode. Rather he was inhaling air into the

492
00:27:47,520 --> 00:27:50,480
Speaker 1: rectum and then releasing it again. Wow. So we talked

493
00:27:50,520 --> 00:27:56,200
Speaker 1: about reverse feeding in our last podcast. Yeah, yeah, right, Yeah.

494
00:27:56,440 --> 00:27:59,160
Speaker 1: It's kind of like if you've ever been generally occasionally

495
00:27:59,240 --> 00:28:01,120
Speaker 1: counter a kid who's doing in this where they'll burp

496
00:28:01,200 --> 00:28:03,080
Speaker 1: over and over again because they're inhaling the air, and

497
00:28:03,080 --> 00:28:04,959
Speaker 1: then they're burping in haling the air and then burping.

498
00:28:05,119 --> 00:28:08,560
Speaker 1: He was doing the same thing but with his bottom.

499
00:28:08,640 --> 00:28:10,520
Speaker 1: I would love to tell some stories about my family,

500
00:28:10,560 --> 00:28:12,720
Speaker 1: but I don't think that would be correct. All I

501
00:28:12,720 --> 00:28:15,840
Speaker 1: can say is that I think maybe in past generations

502
00:28:15,880 --> 00:28:20,359
Speaker 1: we've had some artists excellent. So anyway, on that note,

503
00:28:20,640 --> 00:28:25,200
Speaker 1: we should probably bring closure to this. Yes, let's let's

504
00:28:25,240 --> 00:28:34,840
Speaker 1: call over the robot. Well, that was a robotic fart,

505
00:28:35,040 --> 00:28:36,760
Speaker 1: I know, but really, I mean, I thought this was

506
00:28:36,800 --> 00:28:39,920
Speaker 1: a really classy episode on farts, and here Arnie had

507
00:28:39,960 --> 00:28:42,080
Speaker 1: to come and stink up the joint. It doesn't really smell.

508
00:28:42,200 --> 00:28:44,320
Speaker 1: I mean it just it smells like a train passing

509
00:28:44,320 --> 00:28:48,520
Speaker 1: in a subway or something, you know. Kind of nothing really,

510
00:28:48,560 --> 00:28:51,760
Speaker 1: but don't do it again. Okay, here's some mail from

511
00:28:51,760 --> 00:28:54,720
Speaker 1: our robot. This one is from Adam. Adam writes, and

512
00:28:54,760 --> 00:28:56,960
Speaker 1: he's for solving to responding to our episode Eating Alive,

513
00:28:57,000 --> 00:29:00,280
Speaker 1: where we talked about the prospect of being swallowed whole

514
00:29:00,520 --> 00:29:03,000
Speaker 1: by a sperm whale. And he says, Okay, let's say

515
00:29:03,000 --> 00:29:05,800
Speaker 1: I was swallowed whole by a whale. I'm alive and

516
00:29:06,160 --> 00:29:09,040
Speaker 1: uninjured in the pre stomach. The situation looks grim, but

517
00:29:09,160 --> 00:29:11,320
Speaker 1: alas all hope is not lost, because how did I

518
00:29:11,360 --> 00:29:14,000
Speaker 1: get there? I was inspecting a gaping maw of a

519
00:29:14,040 --> 00:29:16,640
Speaker 1: giant whale while scuba diving. I have a full tank

520
00:29:16,640 --> 00:29:19,160
Speaker 1: of air and a very sharp dive knife, as does

521
00:29:19,200 --> 00:29:22,200
Speaker 1: any diver worth the salt, and a healthy desire to live.

522
00:29:22,480 --> 00:29:24,880
Speaker 1: What are my chances of jabbing and slicing my way

523
00:29:24,920 --> 00:29:29,560
Speaker 1: to freedom? Slim to none. Well, uh, yeah, it's a

524
00:29:29,560 --> 00:29:32,920
Speaker 1: tough one because certainly, those the squid that are being

525
00:29:32,920 --> 00:29:36,640
Speaker 1: swallowed by the sperm whale, they have rather tough beaks,

526
00:29:37,240 --> 00:29:40,280
Speaker 1: so they don't have any bones otherwise, so they can

527
00:29:40,360 --> 00:29:42,880
Speaker 1: kind of they're sort of loot in this in the

528
00:29:42,920 --> 00:29:45,120
Speaker 1: way that they can contort their bodies. Yeah, but they

529
00:29:45,120 --> 00:29:47,960
Speaker 1: could they have the ability to to use that beak

530
00:29:48,200 --> 00:29:52,000
Speaker 1: on on the predator. They're able to to use their

531
00:29:52,560 --> 00:29:56,360
Speaker 1: their their little suction cups with the sharp things. And

532
00:29:56,360 --> 00:29:58,520
Speaker 1: then you see the scars and the sides of sperm

533
00:29:58,520 --> 00:30:01,960
Speaker 1: whales where they've suckered and and and picked at them,

534
00:30:02,200 --> 00:30:04,720
Speaker 1: and well that's creates the ambergies right there. Yeah. Yeah,

535
00:30:04,720 --> 00:30:07,480
Speaker 1: And then yeah. Then of course, once they passed the

536
00:30:07,600 --> 00:30:10,479
Speaker 1: beaks on, they they we discussed in that episode, end

537
00:30:10,560 --> 00:30:14,640
Speaker 1: up scarring the side of the intestinal wall. So I

538
00:30:14,680 --> 00:30:17,040
Speaker 1: don't I feel like if you were too to try

539
00:30:17,080 --> 00:30:19,360
Speaker 1: to use that knife and fight your way out, that

540
00:30:19,400 --> 00:30:22,760
Speaker 1: you're just that's gonna cause the perm whale to really

541
00:30:22,800 --> 00:30:28,040
Speaker 1: gnash its teeth even more. Yeah, and and chaos wouldn't sue. Yeah,

542
00:30:28,400 --> 00:30:30,720
Speaker 1: it hasn't already. Yeah, I'm thinking that. I mean, certainly

543
00:30:30,720 --> 00:30:32,920
Speaker 1: you're not going to cut your way out. I guess

544
00:30:32,960 --> 00:30:36,240
Speaker 1: the only the only possibility here was if you somehow

545
00:30:36,280 --> 00:30:39,320
Speaker 1: create enough of the disturbance to where it vomits you.

546
00:30:39,800 --> 00:30:42,640
Speaker 1: Oh right, if you could just stick your finger down

547
00:30:42,640 --> 00:30:45,760
Speaker 1: its throat. Yeah, or I think I think Pinocchio escaped

548
00:30:45,840 --> 00:30:47,800
Speaker 1: by started They started a little fire, right, and the

549
00:30:47,840 --> 00:30:51,720
Speaker 1: smoke builds up, and then then the creature sneezes everyone free.

550
00:30:51,760 --> 00:30:53,240
Speaker 1: So this is kind of you. Obviously you're not going

551
00:30:53,280 --> 00:30:56,400
Speaker 1: to start a fire in there, um, But if you

552
00:30:56,400 --> 00:30:59,160
Speaker 1: were to stab away and start stabbing the size, would

553
00:30:59,160 --> 00:31:00,920
Speaker 1: you possibly be able to get those firm let us

554
00:31:00,920 --> 00:31:03,800
Speaker 1: put you up? Well, I tend to doubt it if

555
00:31:03,800 --> 00:31:06,560
Speaker 1: you had a little pocket of poison, But then you're

556
00:31:06,600 --> 00:31:08,760
Speaker 1: going to expose yourself to that poison as well. Right,

557
00:31:08,760 --> 00:31:11,160
Speaker 1: I'm trying to think of ways that you could regurgitate.

558
00:31:11,840 --> 00:31:13,920
Speaker 1: We don't know. I bet butt you guys out there

559
00:31:14,000 --> 00:31:15,920
Speaker 1: might have some ideas. Think it over. I would like

560
00:31:15,920 --> 00:31:17,560
Speaker 1: to to hear some people's thoughts on that, and hey,

561
00:31:17,600 --> 00:31:19,600
Speaker 1: may you know we get a spare moment here and there,

562
00:31:19,640 --> 00:31:22,480
Speaker 1: maybe I'll try and contact an expert on this, and

563
00:31:22,920 --> 00:31:25,040
Speaker 1: someone who has survived thinks well, by the way, all

564
00:31:25,080 --> 00:31:27,840
Speaker 1: guess alright, So there you have it. Um, if you

565
00:31:27,880 --> 00:31:29,760
Speaker 1: have some thoughts who would like to share with us,

566
00:31:29,920 --> 00:31:32,920
Speaker 1: particularly about this episode, which I'm sure lots of people

567
00:31:32,920 --> 00:31:35,520
Speaker 1: will have something to share about this episode, about the

568
00:31:35,600 --> 00:31:41,280
Speaker 1: science of late us, about the way culturally we understand farting. Um,

569
00:31:41,720 --> 00:31:43,240
Speaker 1: I know we have listeners from all over the world.

570
00:31:43,240 --> 00:31:45,160
Speaker 1: We haven't listeners who are trying, who have traveled and

571
00:31:45,160 --> 00:31:47,760
Speaker 1: are traveling all over the world. So i'm i'm I'm

572
00:31:47,920 --> 00:31:51,959
Speaker 1: definitely interested in various cultural responses to flate us and

573
00:31:52,080 --> 00:31:55,360
Speaker 1: uh passing gas in public or in private or across

574
00:31:55,560 --> 00:31:58,520
Speaker 1: uh you know, gender profiles. Uh, let us know about

575
00:31:58,560 --> 00:32:00,320
Speaker 1: all this stuff. We would love to hear from you.
