00:00:01,560 --> 00:00:04,720
Speaker 1: Welcome to Stuff from the Science Lab from how stuff

2
00:00:04,760 --> 00:00:15,960
Speaker 1: works dot com. Hey guys, and welcome to the podcast.

3
00:00:16,040 --> 00:00:18,400
Speaker 1: This is Alison Madamouth, the science editor how stuff flix

4
00:00:18,480 --> 00:00:20,560
Speaker 1: dot com. And this is Robert Lamb science We're right

5
00:00:20,640 --> 00:00:23,520
Speaker 1: or how stuff works dot com. Tell me, Allison, have

6
00:00:23,760 --> 00:00:27,600
Speaker 1: you ever secretly wished you had a prosthetic arm, like

7
00:00:27,680 --> 00:00:32,360
Speaker 1: a fake you know, like a robotic hand or anything. Um,

8
00:00:32,479 --> 00:00:36,000
Speaker 1: until this afternoon, I might have answered you with a no.

9
00:00:36,560 --> 00:00:40,199
Speaker 1: But there's some pretty cool prosthetic devices out there and

10
00:00:40,360 --> 00:00:43,360
Speaker 1: a little research into Oscar Pistorius. Have you have you

11
00:00:43,400 --> 00:00:45,159
Speaker 1: heard about this guy? You probably did? Oh, this is

12
00:00:45,200 --> 00:00:49,280
Speaker 1: the blade Runner, right, yeah, yeah, he's awesome. Um, and

13
00:00:49,320 --> 00:00:52,400
Speaker 1: it's funny too because I actually do think about prosthetic

14
00:00:52,440 --> 00:00:54,640
Speaker 1: limbs when I'm when I'm running, that's when I've most

15
00:00:54,640 --> 00:00:56,680
Speaker 1: thought about it, and I think, you know, wow, I'm

16
00:00:56,720 --> 00:00:58,960
Speaker 1: really grateful to have my legs and running and gosh,

17
00:00:59,000 --> 00:01:00,840
Speaker 1: my legs are tired, and maybe I should go get

18
00:01:00,880 --> 00:01:04,280
Speaker 1: a blade Runner like Oscar, Like maybe you should. You

19
00:01:04,280 --> 00:01:07,560
Speaker 1: should lose your legs and replace them with with super

20
00:01:07,640 --> 00:01:11,520
Speaker 1: high tech prosthetics like a cheetah. That thing is awesome. Hey,

21
00:01:11,600 --> 00:01:13,080
Speaker 1: just so you guys know, we are going to be

22
00:01:13,080 --> 00:01:16,920
Speaker 1: talking about prosthetic limbs today, and we know that there

23
00:01:16,920 --> 00:01:18,280
Speaker 1: are a lot of people out there who have lost

24
00:01:18,280 --> 00:01:20,440
Speaker 1: a limb, and we don't take that lightly, but we

25
00:01:20,480 --> 00:01:23,399
Speaker 1: will be talking pretty candidly about it today. Yeah, And uh,

26
00:01:24,760 --> 00:01:26,480
Speaker 1: like I have I have this kind of mixed thing

27
00:01:26,520 --> 00:01:29,800
Speaker 1: about it because as a kid, I loved the idea

28
00:01:29,840 --> 00:01:31,920
Speaker 1: of like having like a robot hand or something because

29
00:01:31,920 --> 00:01:33,280
Speaker 1: it was all over the place. You know. It's like

30
00:01:33,280 --> 00:01:35,480
Speaker 1: you're watching Pirate movies and they have peg legs, or

31
00:01:35,480 --> 00:01:38,240
Speaker 1: you're watching like he Man cartoons and it's kind of

32
00:01:38,360 --> 00:01:40,960
Speaker 1: lockjaw and he had like this big robot arm and

33
00:01:40,959 --> 00:01:43,720
Speaker 1: and so you know, it's and I still find a

34
00:01:43,720 --> 00:01:45,440
Speaker 1: lot of that stuff really cool. You know. It's all that,

35
00:01:45,600 --> 00:01:48,800
Speaker 1: you know, a billion dollar man type of thing, you know, um,

36
00:01:48,840 --> 00:01:53,320
Speaker 1: and you know, cyborgs and making somebody stronger through technology,

37
00:01:53,840 --> 00:01:56,040
Speaker 1: h and impervious. You know. But then at the same time,

38
00:01:56,080 --> 00:01:58,080
Speaker 1: I like, I'll think about it, you know, I'll be

39
00:01:58,080 --> 00:01:59,680
Speaker 1: like typing or something like, man, if I lost a

40
00:01:59,720 --> 00:02:02,640
Speaker 1: hand would really suck, Like how would I move my mouse?

41
00:02:02,840 --> 00:02:05,920
Speaker 1: You know? Um, you know, and well you might not

42
00:02:06,000 --> 00:02:09,360
Speaker 1: use that fictionality with some of the technologies available today.

43
00:02:09,480 --> 00:02:11,359
Speaker 1: That's right, and we're going to talk about some of them,

44
00:02:11,400 --> 00:02:14,760
Speaker 1: but can we talk about Oscar for a second blade runner? Yeah, yeah,

45
00:02:14,880 --> 00:02:17,040
Speaker 1: we were talking about him. So just a reminder for

46
00:02:17,040 --> 00:02:18,360
Speaker 1: those of you guys who don't remember him. He used

47
00:02:18,360 --> 00:02:20,240
Speaker 1: the sprinter who was on track to make the South

48
00:02:20,280 --> 00:02:24,000
Speaker 1: African Olympic team. And according to a Wired story by

49
00:02:24,080 --> 00:02:27,360
Speaker 1: Josh mqugh, this was an Oscar story. He was born

50
00:02:27,400 --> 00:02:30,399
Speaker 1: with two toes on each tiny foot, and each leg

51
00:02:30,440 --> 00:02:33,000
Speaker 1: was missing its fibula. And the fibula is that long,

52
00:02:33,040 --> 00:02:35,880
Speaker 1: thin bone that connects your calf muscle and it forms

53
00:02:35,880 --> 00:02:40,160
Speaker 1: outside the ankle. So they were pretty bad shape. Yeah,

54
00:02:40,200 --> 00:02:43,120
Speaker 1: it was missing actually, So it was pretty much a

55
00:02:43,120 --> 00:02:46,120
Speaker 1: situation of either keep these and use a wheelchair for

56
00:02:46,120 --> 00:02:49,920
Speaker 1: the rest of your life, or double amputee and sort

57
00:02:49,919 --> 00:02:52,720
Speaker 1: of start from scratch, put some prosthetics on there and

58
00:02:53,080 --> 00:02:54,600
Speaker 1: you know, and learn how to use them at an

59
00:02:54,639 --> 00:02:57,320
Speaker 1: early age, right, So Oscar's parents obviously went with the

60
00:02:57,760 --> 00:03:00,720
Speaker 1: latter choice, and at each one and a off. According

61
00:03:00,760 --> 00:03:03,600
Speaker 1: to a Wired arter mceugh, the Storiers took his first

62
00:03:03,600 --> 00:03:06,840
Speaker 1: steps on a set of fiber last pigs, and now

63
00:03:06,880 --> 00:03:08,480
Speaker 1: he's pretty darned fast on them, just to give you

64
00:03:08,560 --> 00:03:10,960
Speaker 1: an idea of how fast he can cover nine point

65
00:03:11,000 --> 00:03:13,639
Speaker 1: four meters per second on them. Yeah, and if you

66
00:03:13,639 --> 00:03:15,440
Speaker 1: haven't seen a picture of these, I mean, do have

67
00:03:15,480 --> 00:03:17,960
Speaker 1: do a search for it, because it's it's really awesome.

68
00:03:18,000 --> 00:03:20,000
Speaker 1: I think either this guy or a guy with a

69
00:03:20,040 --> 00:03:22,280
Speaker 1: pair of these showed up in the first season of

70
00:03:22,360 --> 00:03:25,000
Speaker 1: My Name is Earl, No kidding. Yeah, he like runs

71
00:03:25,000 --> 00:03:26,680
Speaker 1: around on him and it looks awesome because they have

72
00:03:26,720 --> 00:03:29,600
Speaker 1: this like they've been backwards and they're like springing in

73
00:03:29,639 --> 00:03:31,760
Speaker 1: to the untrained eye, they look just like a curved

74
00:03:31,760 --> 00:03:34,240
Speaker 1: piece of metal, you know, and not something that's like

75
00:03:34,400 --> 00:03:36,000
Speaker 1: ultra you know. It looks a little bit like a

76
00:03:36,000 --> 00:03:39,200
Speaker 1: hockey like a hockey stick. And yeah, imagine a guy

77
00:03:39,280 --> 00:03:42,440
Speaker 1: like running on like hockey sticks and except just having

78
00:03:42,480 --> 00:03:44,640
Speaker 1: like this awesome spring to his step and just like

79
00:03:44,800 --> 00:03:47,000
Speaker 1: really fast. It's it's kind of amazing. Yeah, and they're

80
00:03:47,000 --> 00:03:49,280
Speaker 1: pretty expensive too for all that spring and power. There

81
00:03:49,280 --> 00:03:52,680
Speaker 1: between fifteen thousand and eighteen thousand, uh per per cheetah

82
00:03:52,680 --> 00:03:56,280
Speaker 1: per blate. So stories is fate for the two thousand

83
00:03:56,280 --> 00:03:59,160
Speaker 1: and eight Olympics was that he eventually was cleared and

84
00:03:59,400 --> 00:04:00,520
Speaker 1: he was going to be able to run in the

85
00:04:00,560 --> 00:04:04,080
Speaker 1: Beijing Olympics if you qualified. Um, but he in fact didn't.

86
00:04:04,360 --> 00:04:06,600
Speaker 1: He didn't he didn't make the Olympic qualifying standard in

87
00:04:06,640 --> 00:04:10,040
Speaker 1: the four hundred. But this is kind of interesting. I

88
00:04:10,120 --> 00:04:13,640
Speaker 1: was thinking about it. I mean, Oscar is so fast

89
00:04:13,760 --> 00:04:17,080
Speaker 1: that I was wondering, you know, with these types of

90
00:04:17,160 --> 00:04:21,719
Speaker 1: cheetah blades and and these type of prosthetic devices, could

91
00:04:21,760 --> 00:04:25,200
Speaker 1: we eventually see the Paralympics, you know, breaking records that

92
00:04:25,320 --> 00:04:28,560
Speaker 1: the Olympic athletes camp. I don't know, it's worth it's

93
00:04:28,560 --> 00:04:30,799
Speaker 1: worth thinking about. You know. It's the as the technology

94
00:04:30,839 --> 00:04:34,800
Speaker 1: improves and we we get we're better able to to

95
00:04:35,000 --> 00:04:37,479
Speaker 1: replicate you know, the use we would get out of

96
00:04:37,160 --> 00:04:39,960
Speaker 1: an actual limb, you know, stands the reason we might

97
00:04:39,960 --> 00:04:42,400
Speaker 1: reach the point where we could you know, improve upon

98
00:04:42,440 --> 00:04:45,960
Speaker 1: the design to certain degree and improve they have. Prosthetic

99
00:04:46,000 --> 00:04:48,919
Speaker 1: devices have come a long way. Yeah, there was you know,

100
00:04:49,200 --> 00:04:51,320
Speaker 1: there was a time long ago where have you lost

101
00:04:51,320 --> 00:04:54,200
Speaker 1: your arm to a you know, a savor tooth tiger

102
00:04:54,279 --> 00:04:57,080
Speaker 1: and whatnot. Then I don't know about a savor tooth.

103
00:04:57,120 --> 00:04:59,600
Speaker 1: I'm not sure about the crossover. They would say, Willy

104
00:04:59,640 --> 00:05:01,919
Speaker 1: mammoth bits your arm off you know, you wouldn't be

105
00:05:01,920 --> 00:05:04,640
Speaker 1: able to really get a prosthetic but but they really

106
00:05:04,640 --> 00:05:07,040
Speaker 1: started popping up pretty early in history. Did they found

107
00:05:07,040 --> 00:05:09,320
Speaker 1: one on a mummy? Didn't they like a fake toe? Yes?

108
00:05:09,360 --> 00:05:11,400
Speaker 1: They did. They found a three thousand year old fake

109
00:05:11,480 --> 00:05:14,400
Speaker 1: toe on an Egyptian noblewoman. Yeah. And oh, and tell

110
00:05:14,400 --> 00:05:16,720
Speaker 1: me about the Roman dude. I will tell you about

111
00:05:16,760 --> 00:05:19,520
Speaker 1: the Roman dude. The Roman dude was a guy named

112
00:05:19,560 --> 00:05:21,880
Speaker 1: Marcus Surgis, and he was a Roman general who lost

113
00:05:21,920 --> 00:05:24,000
Speaker 1: his right hand while he was battling in the one

114
00:05:24,040 --> 00:05:28,560
Speaker 1: of one of the Panick Wars, and Marcus ordered a

115
00:05:28,600 --> 00:05:31,479
Speaker 1: replacement hand made of iron to hold his shield, and

116
00:05:31,560 --> 00:05:33,719
Speaker 1: he he got his Roman self back out there on

117
00:05:33,760 --> 00:05:36,320
Speaker 1: the battlefield. That was a tough guy. Yeah, and this

118
00:05:36,400 --> 00:05:39,440
Speaker 1: is this ties into the whole like childhood, like you know,

119
00:05:39,600 --> 00:05:41,440
Speaker 1: love of the idea of prosthetic limbs. Like here's a

120
00:05:41,480 --> 00:05:43,160
Speaker 1: guy that's so awesome. He like goes out and he's,

121
00:05:43,240 --> 00:05:46,359
Speaker 1: you know, he's a he's this you know, action killing machine.

122
00:05:46,400 --> 00:05:48,040
Speaker 1: And then like they take his hand and he's like

123
00:05:48,560 --> 00:05:50,520
Speaker 1: I can just you know, slap a shield on there

124
00:05:50,560 --> 00:05:53,760
Speaker 1: and I'm good to go. So that's that's pretty impressive.

125
00:05:54,040 --> 00:05:56,200
Speaker 1: So one thing is that Old Marcus may have been

126
00:05:56,240 --> 00:05:59,040
Speaker 1: buried with his amputated limb, because people used to believe

127
00:05:59,080 --> 00:06:01,600
Speaker 1: that if you lost a limb while you were on earth,

128
00:06:01,640 --> 00:06:04,160
Speaker 1: that you should be buried with it, because otherwise you

129
00:06:04,400 --> 00:06:06,920
Speaker 1: might be limbless in the afterlife as well. It kind

130
00:06:06,920 --> 00:06:09,480
Speaker 1: of like with the mummies in the Coptic jars with

131
00:06:09,560 --> 00:06:12,960
Speaker 1: their organs and them. But of course, what road group

132
00:06:12,960 --> 00:06:15,920
Speaker 1: in history was renowned for their prosthetics. That would be

133
00:06:16,000 --> 00:06:21,240
Speaker 1: the pirates indeed, and we'll go ahead, sorry, Oh, it's

134
00:06:21,240 --> 00:06:24,680
Speaker 1: just gonna point out that in the Atlanta area there's

135
00:06:24,680 --> 00:06:28,479
Speaker 1: actually an amputee Prosthetic clinic Um and they have a

136
00:06:28,839 --> 00:06:31,400
Speaker 1: they have a pirate on the sign, like a cartoon pirate,

137
00:06:32,080 --> 00:06:34,320
Speaker 1: and their their phone number. I probably can't give out

138
00:06:34,320 --> 00:06:36,720
Speaker 1: the first part of it, but it's like, you know, like,

139
00:06:36,800 --> 00:06:40,400
Speaker 1: you know whatever, whatever, fake leg you know. Okay, So

140
00:06:40,480 --> 00:06:42,799
Speaker 1: that's direct and to the point. Yeah, and and interesting

141
00:06:42,800 --> 00:06:44,360
Speaker 1: too because it's like, you know, they seem to have

142
00:06:44,400 --> 00:06:46,280
Speaker 1: a real sense of humor or you know, about the

143
00:06:46,800 --> 00:06:51,040
Speaker 1: use of prosthetics and love pirates. So it's interesting. Yeah.

144
00:06:51,120 --> 00:06:53,280
Speaker 1: So back in the back in the olden days of

145
00:06:53,320 --> 00:06:55,640
Speaker 1: wood and metal and leather with the were the materials

146
00:06:55,640 --> 00:06:58,839
Speaker 1: of choice for for your prosthetic limbs. But now we've

147
00:06:58,880 --> 00:07:00,680
Speaker 1: we've become kind of high tech because we're talking a

148
00:07:00,720 --> 00:07:03,839
Speaker 1: little bit about with oscar. So let's talk about some

149
00:07:03,880 --> 00:07:05,640
Speaker 1: of the newer ones. And meanwhile, we should probably give

150
00:07:05,640 --> 00:07:07,640
Speaker 1: you a little run through through the basic parts of

151
00:07:07,640 --> 00:07:12,560
Speaker 1: a prosthetic limb. Yeah, these are the basics. Um, you're

152
00:07:12,560 --> 00:07:15,040
Speaker 1: gonna want. You're gonna want a pie one, you sure will,

153
00:07:15,120 --> 00:07:17,880
Speaker 1: because it's like the heart of the prosthetic. Yeah, this

154
00:07:17,960 --> 00:07:20,720
Speaker 1: is I mean, this is like the skeleton, internal frame.

155
00:07:20,960 --> 00:07:24,520
Speaker 1: You know, this is replacing the bone that was lost essentially, right,

156
00:07:24,520 --> 00:07:27,360
Speaker 1: it's providing the structural support. And you used to be

157
00:07:27,440 --> 00:07:30,640
Speaker 1: often made from metal rods. Nowadays you might be looking

158
00:07:30,680 --> 00:07:34,560
Speaker 1: at a lighter carbon fiber type composite. And then you

159
00:07:34,600 --> 00:07:37,400
Speaker 1: have the socket, right, And so the socket is the

160
00:07:37,440 --> 00:07:40,720
Speaker 1: part of the prosthetic device that meets the residual limb

161
00:07:40,800 --> 00:07:43,320
Speaker 1: or the limb stump as the case maybe. And a

162
00:07:43,320 --> 00:07:45,240
Speaker 1: good few here is obviously going to be critical because

163
00:07:45,240 --> 00:07:47,320
Speaker 1: you don't want that thing rubbing against you the wrong way.

164
00:07:47,400 --> 00:07:50,760
Speaker 1: I mean, come on, yeah, yeah, So good fit here

165
00:07:50,920 --> 00:07:54,080
Speaker 1: is really critical. And then lastly, you have the suspension system,

166
00:07:54,080 --> 00:07:55,760
Speaker 1: you gotta have something to attach it to your body

167
00:07:55,800 --> 00:07:57,280
Speaker 1: or make sure it stays on. And this could be

168
00:07:57,440 --> 00:08:01,240
Speaker 1: you know, whether it's just a suction which is pretty cool, um,

169
00:08:01,400 --> 00:08:03,640
Speaker 1: or you might have some sort of harness system or

170
00:08:03,680 --> 00:08:06,160
Speaker 1: a strap at belt or sleeve and uh, they can

171
00:08:06,200 --> 00:08:10,560
Speaker 1: be pretty inconspicuous. Yeah, um, but yeah, I guess there's

172
00:08:10,600 --> 00:08:13,560
Speaker 1: the strap ones are kind of the old model, right right,

173
00:08:13,560 --> 00:08:16,360
Speaker 1: and I think this section is is more current. Um,

174
00:08:16,400 --> 00:08:18,080
Speaker 1: but let's talk about some of the super cool ones.

175
00:08:18,240 --> 00:08:20,920
Speaker 1: Enough with the definition stuff, let's set to So why

176
00:08:20,960 --> 00:08:22,360
Speaker 1: don't we have such a need for this? I mean,

177
00:08:22,400 --> 00:08:25,320
Speaker 1: war definitely, um. I mean you have somebody rolling over

178
00:08:25,360 --> 00:08:29,000
Speaker 1: a roadside bomb and maybe they actually survive that incident,

179
00:08:29,080 --> 00:08:30,480
Speaker 1: but they lose a limb. In fact, a lot of

180
00:08:30,520 --> 00:08:33,840
Speaker 1: soldiers are coming back from Afghanistan and Iraq and uh

181
00:08:34,040 --> 00:08:35,880
Speaker 1: theaters around the world, and you know they've lost a

182
00:08:35,920 --> 00:08:38,160
Speaker 1: limb or they've lost multiple limbs. And then you have

183
00:08:38,240 --> 00:08:39,640
Speaker 1: areas the world where you still have a lot of

184
00:08:39,679 --> 00:08:44,040
Speaker 1: land mines and unexploded unexploded ordinance. So um, you know

185
00:08:44,120 --> 00:08:47,360
Speaker 1: people are losing limbs sadly to that, right, and then

186
00:08:47,360 --> 00:08:50,680
Speaker 1: you throw an accidents with machinery or fireworks, and you

187
00:08:50,720 --> 00:08:53,720
Speaker 1: have a pretty major need in both developing and developed countries.

188
00:08:53,960 --> 00:08:55,720
Speaker 1: Now this is something that I was really I found

189
00:08:55,760 --> 00:08:59,160
Speaker 1: really exciting. And this is they called this ostio integration,

190
00:08:59,400 --> 00:09:04,040
Speaker 1: right and uh and this is a apparently titanium can

191
00:09:04,080 --> 00:09:07,200
Speaker 1: be made to to actually fuse with the bone. Oh right,

192
00:09:07,280 --> 00:09:09,360
Speaker 1: I was heading about that in popular mechanics. Yeah. Yeah,

193
00:09:09,360 --> 00:09:11,840
Speaker 1: so this is like the ultimate you know, talking about

194
00:09:11,880 --> 00:09:14,040
Speaker 1: anchoring systems, Like if you can actually anchor it to

195
00:09:14,080 --> 00:09:16,920
Speaker 1: the bone, um, you know, in a very you know,

196
00:09:17,000 --> 00:09:20,000
Speaker 1: firm manner, then then that's that's better than any of

197
00:09:20,000 --> 00:09:22,800
Speaker 1: these methods. Um. Yeah. And so far they've used it

198
00:09:22,840 --> 00:09:26,640
Speaker 1: in a like dental um and facial implants, and of

199
00:09:26,679 --> 00:09:29,200
Speaker 1: course now it's being considered for limb prosthetics. Yeah. Well

200
00:09:29,200 --> 00:09:32,160
Speaker 1: they used it on German shepherd named Cassidy. Indeed they did.

201
00:09:32,240 --> 00:09:34,720
Speaker 1: And it looks like North Carolina State University is going

202
00:09:34,760 --> 00:09:36,679
Speaker 1: to try us six more of these operations in two

203
00:09:36,720 --> 00:09:41,720
Speaker 1: thousand ten that involve asso integration on impute dogs and

204
00:09:41,760 --> 00:09:46,080
Speaker 1: possibly an aweso lot. It's I mean, it's amazing like

205
00:09:46,120 --> 00:09:49,040
Speaker 1: some of the animal prosthetically come up with which on

206
00:09:49,080 --> 00:09:50,760
Speaker 1: all one level. It's like it's like this is the

207
00:09:50,840 --> 00:09:53,600
Speaker 1: place to test you know, technologies, you know, because animals

208
00:09:53,640 --> 00:09:55,839
Speaker 1: are really bad about like losing limbs. You know how

209
00:09:55,840 --> 00:09:59,280
Speaker 1: many three legged cats and dogs you see all the time, right,

210
00:09:59,280 --> 00:10:01,520
Speaker 1: and it never see to make a darn bit of difference. Well,

211
00:10:01,640 --> 00:10:05,120
Speaker 1: they don't really generally, they don't seem to care. Yeah,

212
00:10:05,360 --> 00:10:07,800
Speaker 1: I'm good. Yeah, but you sent me a picture of

213
00:10:07,800 --> 00:10:15,360
Speaker 1: the elephant with the prosthetic yeah, from the tie Burmese border. Um. Yeah,

214
00:10:15,360 --> 00:10:17,400
Speaker 1: I lost the leg and they created this this prosthetic

215
00:10:17,520 --> 00:10:20,319
Speaker 1: leg for an elephant that was pretty pretty amazing. And

216
00:10:20,440 --> 00:10:22,160
Speaker 1: we also saw when we were like when we were

217
00:10:22,200 --> 00:10:26,600
Speaker 1: researching this of the bill. Oh yeah, the Romanian start

218
00:10:26,720 --> 00:10:31,960
Speaker 1: name Uzonka sus Lanka's Lanka got a processus. Yeah, like

219
00:10:32,040 --> 00:10:35,319
Speaker 1: somebody had been mean to these birds, to this bird

220
00:10:35,360 --> 00:10:37,880
Speaker 1: and damaged its bill, and they created a prosthetic bill

221
00:10:37,920 --> 00:10:40,560
Speaker 1: so it can function. More recently, I saw Dean Cayman's one.

222
00:10:40,600 --> 00:10:43,360
Speaker 1: Did you see the video on the Colbert Show or yeah, yeah,

223
00:10:43,360 --> 00:10:45,760
Speaker 1: with that awesome hand right, very high five Colbert with

224
00:10:45,800 --> 00:10:50,280
Speaker 1: a this prosthetic arm. Yeah. So this was the founder

225
00:10:50,280 --> 00:10:53,840
Speaker 1: of first Dean Cayman and it's pretty cool. Yeah, as

226
00:10:53,880 --> 00:10:56,200
Speaker 1: far as I know, it's it's not available, but the

227
00:10:56,240 --> 00:10:59,280
Speaker 1: technology is is pretty advanced. So this arm can pick

228
00:10:59,360 --> 00:11:01,240
Speaker 1: up a raisin or a grape on the table without

229
00:11:01,280 --> 00:11:04,600
Speaker 1: destroying it. So it has dexterity, it has uh those

230
00:11:04,679 --> 00:11:07,880
Speaker 1: fine motor skills down and Caman actually got the request

231
00:11:07,920 --> 00:11:11,160
Speaker 1: from DARPA. UM. DARPA said, hey, we want the vets

232
00:11:11,160 --> 00:11:14,719
Speaker 1: to come back and have better technologies available to them. UM,

233
00:11:14,760 --> 00:11:18,320
Speaker 1: and MPG technology really isn't there right now. So Caman

234
00:11:18,360 --> 00:11:19,599
Speaker 1: has been working on this for a while and he

235
00:11:19,640 --> 00:11:21,520
Speaker 1: wound up taking it down to the Walter Reed Military

236
00:11:21,559 --> 00:11:26,000
Speaker 1: Hospital and testing it up. The arm consense pressure and

237
00:11:26,040 --> 00:11:29,320
Speaker 1: temperature and basically the more pneumatic pressure you put on it,

238
00:11:29,320 --> 00:11:32,520
Speaker 1: the more it's attached. Cool. Some of that technology, um,

239
00:11:33,000 --> 00:11:35,920
Speaker 1: you know, was explored in the in the space industry

240
00:11:36,760 --> 00:11:39,240
Speaker 1: for space gloves the big thing because if you know,

241
00:11:39,280 --> 00:11:42,160
Speaker 1: if you have this huge thick layer between yourself and

242
00:11:42,240 --> 00:11:45,000
Speaker 1: say sensitive you know, equipment on a satellite you're trying

243
00:11:45,000 --> 00:11:47,240
Speaker 1: to repair, you know, you know, it's like trying to

244
00:11:47,280 --> 00:11:50,960
Speaker 1: play piano when you know, kitchen mits or something. Yeah. Right,

245
00:11:51,280 --> 00:11:53,960
Speaker 1: So so the idea here is, you know, create gloves

246
00:11:54,000 --> 00:11:57,000
Speaker 1: that can sense those things and can transfer those back

247
00:11:57,040 --> 00:11:59,720
Speaker 1: to the wear right in case you're just sparing. You know,

248
00:12:00,080 --> 00:12:02,160
Speaker 1: it sounds like a lot of these technologies aren't available. Well,

249
00:12:02,160 --> 00:12:04,240
Speaker 1: some of them are actually, um there are a lot

250
00:12:04,240 --> 00:12:06,520
Speaker 1: of companies operating the space, and some of these cutting

251
00:12:06,600 --> 00:12:10,280
Speaker 1: edge prosthetics are already available. So there's one device that

252
00:12:10,320 --> 00:12:12,320
Speaker 1: I read about called pro Digits, and it's made by

253
00:12:12,320 --> 00:12:15,800
Speaker 1: a Scottish company, um by the name of Touch Bionics.

254
00:12:16,040 --> 00:12:19,440
Speaker 1: And this particular device can replace any or all fingers

255
00:12:19,440 --> 00:12:21,880
Speaker 1: on your hand, and it comes with this like tiny

256
00:12:21,880 --> 00:12:24,079
Speaker 1: little motor and a gearbox that's founded at the base

257
00:12:25,160 --> 00:12:28,760
Speaker 1: and they're commercially available. Okay, so here's the thing. Big

258
00:12:28,800 --> 00:12:33,160
Speaker 1: cost sixty dollars to seventy five dollars and that's going

259
00:12:33,200 --> 00:12:36,360
Speaker 1: to include fitting and occupational therapy. My question is, I

260
00:12:36,360 --> 00:12:38,880
Speaker 1: wonder if the Veterans Administration would cover this. I mean,

261
00:12:38,920 --> 00:12:40,719
Speaker 1: how much is that? How much of that cost is

262
00:12:40,720 --> 00:12:43,640
Speaker 1: going to be covered for an amputee? You know, how

263
00:12:43,720 --> 00:12:45,240
Speaker 1: much are we how much is you know the government

264
00:12:45,280 --> 00:12:48,280
Speaker 1: can contribute towards that. Yeah, so it seems like it's

265
00:12:48,280 --> 00:12:50,679
Speaker 1: a little price you still well, but I mean it's

266
00:12:50,720 --> 00:12:52,079
Speaker 1: it's you know it' kind of like a pr thing.

267
00:12:52,120 --> 00:12:54,760
Speaker 1: You know, it's like you're gonna convince people to join

268
00:12:54,800 --> 00:12:57,439
Speaker 1: the army when you know, they see people with missing

269
00:12:57,480 --> 00:13:01,160
Speaker 1: limbs everywhere that if everybody's got really you know, awesome prosthetics,

270
00:13:01,440 --> 00:13:03,440
Speaker 1: it's probably not even gonna be visible. And if you know,

271
00:13:03,480 --> 00:13:05,920
Speaker 1: and if it is visible, you'll say, hey, they really

272
00:13:05,920 --> 00:13:08,320
Speaker 1: take care of those guys after they took one for

273
00:13:08,600 --> 00:13:12,680
Speaker 1: the team. Right, And just to emphasize the motions on

274
00:13:12,679 --> 00:13:15,720
Speaker 1: this particular pro digit device, I mean, you can write

275
00:13:15,720 --> 00:13:18,640
Speaker 1: with it. I read one thing where the guy said

276
00:13:18,640 --> 00:13:21,120
Speaker 1: that his handwriting was in facted better than it was before,

277
00:13:21,240 --> 00:13:22,960
Speaker 1: so he was very pleased with this. All some of

278
00:13:23,040 --> 00:13:25,480
Speaker 1: us have really bad handwriting. So I mean, would you

279
00:13:25,480 --> 00:13:30,439
Speaker 1: include yourself? Yeah? Yeah. One thing I found really interesting

280
00:13:30,440 --> 00:13:35,080
Speaker 1: about about amputees is apparently about half of them, according

281
00:13:35,080 --> 00:13:37,640
Speaker 1: to a two tho article on the US Navy website,

282
00:13:38,120 --> 00:13:42,680
Speaker 1: suffer from um phantomal impain. Right, So this is pain

283
00:13:42,720 --> 00:13:44,560
Speaker 1: that feels like it's coming from a body part that's

284
00:13:44,559 --> 00:13:47,640
Speaker 1: no longer they're according to the Mayo Clinic. And according

285
00:13:47,640 --> 00:13:50,440
Speaker 1: to the clinic, this type of pain was once considered psychological.

286
00:13:50,600 --> 00:13:52,480
Speaker 1: You know, people, I don't know about that. But now

287
00:13:52,520 --> 00:13:55,920
Speaker 1: we figured out that these um sensations originate in the

288
00:13:55,960 --> 00:13:58,240
Speaker 1: spinal cord in the brain. And I read a really

289
00:13:58,240 --> 00:14:00,440
Speaker 1: cool New Yorker article about this a wild back, and

290
00:14:00,559 --> 00:14:03,520
Speaker 1: it was profiling a behavioral neurologist by the name of

291
00:14:03,559 --> 00:14:08,240
Speaker 1: A Villa Yaner Rama Chandron. Apologies to Dr rama Chandron

292
00:14:08,280 --> 00:14:10,480
Speaker 1: if I messed up your name. And he was working

293
00:14:10,520 --> 00:14:12,880
Speaker 1: on this phantom limp pain problem and he came up

294
00:14:12,880 --> 00:14:15,840
Speaker 1: with something called mirror therapy. Oh yeah, I've seen some

295
00:14:15,880 --> 00:14:18,680
Speaker 1: stuff about this. Yeah, right, so we know that phantom

296
00:14:18,720 --> 00:14:22,360
Speaker 1: limpain can be pretty cute, and uh so the neual

297
00:14:22,560 --> 00:14:24,720
Speaker 1: just had this idea to use mirror therapy. And what

298
00:14:24,800 --> 00:14:28,920
Speaker 1: this involves is that you hold up a mirror and

299
00:14:29,000 --> 00:14:31,640
Speaker 1: say you're missing a leg, and you hold up a

300
00:14:31,640 --> 00:14:34,120
Speaker 1: mirror next to your leg, and so it appears as

301
00:14:34,120 --> 00:14:37,520
Speaker 1: if you have two legs. For some reason, this UM

302
00:14:37,560 --> 00:14:39,480
Speaker 1: this helps out with your brain and the pain that

303
00:14:39,480 --> 00:14:42,080
Speaker 1: you're experiencing, and it seems to work, or at least

304
00:14:42,080 --> 00:14:45,680
Speaker 1: it reduces the pain too tolerable levels, and in some

305
00:14:45,760 --> 00:14:50,280
Speaker 1: people it may reduce the pain entirely. That's pretty cool.

306
00:14:50,400 --> 00:14:52,640
Speaker 1: I mean, it's pretty innovative and a really simple therapy

307
00:14:52,680 --> 00:14:54,440
Speaker 1: that could be available to a lot of people. Who

308
00:14:54,680 --> 00:14:57,200
Speaker 1: do you need it? So we talked about phantom limpain.

309
00:14:57,200 --> 00:15:00,720
Speaker 1: I want to talk about something called apo to no ophelia.

310
00:15:01,000 --> 00:15:03,120
Speaker 1: Have you heard of this before today? Yeah? Yeah, this

311
00:15:03,160 --> 00:15:05,600
Speaker 1: is when I've read about a while back. This is

312
00:15:05,640 --> 00:15:09,360
Speaker 1: where you have this uh, this compulsion or even a

313
00:15:09,400 --> 00:15:13,680
Speaker 1: desire to amputate part of your body. Right right. So

314
00:15:13,800 --> 00:15:16,960
Speaker 1: there's a John Hopkins psychologist back in nineteen seven called

315
00:15:17,120 --> 00:15:22,000
Speaker 1: John Money. How awesome is that name? It's funny, especially

316
00:15:22,040 --> 00:15:24,040
Speaker 1: if you know he had a doctoral degree and he

317
00:15:24,040 --> 00:15:27,160
Speaker 1: could call himself doctor Money. Yeah. I never understand when

318
00:15:27,160 --> 00:15:30,120
Speaker 1: people have those weird names, like if like Dennis get

319
00:15:30,240 --> 00:15:33,160
Speaker 1: names like Dr Payne, like you know, I would consider

320
00:15:33,360 --> 00:15:36,320
Speaker 1: changing it. Yeah, yeah, or at least fellow with the way.

321
00:15:36,440 --> 00:15:40,840
Speaker 1: Did you ever see that Seinfeld with the practologist. Yeah?

322
00:15:40,880 --> 00:15:44,800
Speaker 1: What was his name? That's what I'm thinking of right now.

323
00:15:45,160 --> 00:15:48,920
Speaker 1: But anyway, um appa time Nophelia was also called the

324
00:15:49,120 --> 00:15:54,400
Speaker 1: body integrity identity disorder and also ampute identity disorder, and

325
00:15:54,400 --> 00:15:56,520
Speaker 1: it was submitted for inclusion in the d s M five.

326
00:15:56,760 --> 00:15:59,240
Speaker 1: Remember the DSM five. It's like the mental health Bible

327
00:15:59,280 --> 00:16:02,680
Speaker 1: where all the mental health illnesses get classified. Yeah, if

328
00:16:02,720 --> 00:16:05,760
Speaker 1: I remember correctly, this is one that, like some interpretations

329
00:16:05,760 --> 00:16:09,040
Speaker 1: of this, at least with some some people who suffer

330
00:16:09,120 --> 00:16:11,360
Speaker 1: from it, it sometimes stems from being like a really

331
00:16:11,440 --> 00:16:14,200
Speaker 1: high pressure situation where they feel like they need to

332
00:16:14,960 --> 00:16:16,880
Speaker 1: It's almost like you're you're expecting a lot of me,

333
00:16:16,920 --> 00:16:18,560
Speaker 1: but you would expect less of me if I was

334
00:16:18,600 --> 00:16:21,200
Speaker 1: missing a hand before, I have a compulsion to remove

335
00:16:21,280 --> 00:16:24,760
Speaker 1: set a hand. So I was sort of thinking a

336
00:16:24,840 --> 00:16:28,360
Speaker 1: similar to transgender folks, you know, along the lines of

337
00:16:28,400 --> 00:16:31,920
Speaker 1: feeling illinies in your own body, and then once you

338
00:16:31,960 --> 00:16:35,280
Speaker 1: remove a limb, you know, it's sort of you become yourself.

339
00:16:35,920 --> 00:16:37,920
Speaker 1: May you become at peace with yourself? It's I I

340
00:16:38,040 --> 00:16:40,680
Speaker 1: just it kind of blows my mind um to to

341
00:16:40,800 --> 00:16:43,760
Speaker 1: voluntarily seek out in operation where you might I want

342
00:16:43,760 --> 00:16:45,440
Speaker 1: to get rid of a limb. But there's a huge

343
00:16:45,440 --> 00:16:47,560
Speaker 1: black market for it, and of course the Internet has

344
00:16:48,080 --> 00:16:50,000
Speaker 1: a looted all sorts of people seeking these kinds of

345
00:16:50,000 --> 00:16:52,720
Speaker 1: operations too, So it's like a can dude on Craig's List.

346
00:16:52,800 --> 00:16:54,400
Speaker 1: It will come and chop your hand off if you

347
00:16:55,280 --> 00:16:59,440
Speaker 1: well know. Because obviously doctors have some have some legal

348
00:16:59,480 --> 00:17:01,360
Speaker 1: issues with but there was a doctor that I bait about.

349
00:17:01,360 --> 00:17:03,720
Speaker 1: I believe in Scotland he performed to such operations and

350
00:17:03,720 --> 00:17:06,560
Speaker 1: he said that these operations were some of the most

351
00:17:06,560 --> 00:17:09,200
Speaker 1: satisfying he performed in his life because he really feelt

352
00:17:09,240 --> 00:17:11,920
Speaker 1: like he was helping these people to become more comfortable

353
00:17:11,960 --> 00:17:16,280
Speaker 1: with themselves. I mean, I, having never experienced this particularly disorder,

354
00:17:16,680 --> 00:17:19,480
Speaker 1: I can't understand the compulsion, but I believe that it

355
00:17:19,560 --> 00:17:21,920
Speaker 1: must be a very strong compulsion. How could it not be,

356
00:17:22,119 --> 00:17:24,960
Speaker 1: I don't know, I see, I can't imagine how it

357
00:17:25,000 --> 00:17:26,359
Speaker 1: seems like that kind of thing would keep going to

358
00:17:26,359 --> 00:17:28,439
Speaker 1: be kind of like surgical addiction. You know. It's like

359
00:17:28,520 --> 00:17:31,720
Speaker 1: it's people are never happy with anything. You know. It's like,

360
00:17:31,960 --> 00:17:34,680
Speaker 1: you know, somebody gets the you know, an Xbox three sixty,

361
00:17:34,720 --> 00:17:36,439
Speaker 1: they're gonna want to p S three or something. You know.

362
00:17:36,520 --> 00:17:38,439
Speaker 1: It's like so it's like you lose one hand. I mean,

363
00:17:38,440 --> 00:17:40,359
Speaker 1: how is that going to make the person happy? Or

364
00:17:40,400 --> 00:17:42,760
Speaker 1: are they gonna have to lose another hand? Now? I

365
00:17:42,800 --> 00:17:45,160
Speaker 1: don't know. I'm always wanting more. So It's like if

366
00:17:45,440 --> 00:17:47,880
Speaker 1: there's a dude out there that like cutting his hand

367
00:17:47,880 --> 00:17:49,560
Speaker 1: off makes him happy for the rest of his life.

368
00:17:49,600 --> 00:17:52,399
Speaker 1: Like I can't think of anything else in life that

369
00:17:52,600 --> 00:17:57,280
Speaker 1: like does that for anybody? You know, like sheer happiness

370
00:17:57,320 --> 00:17:59,240
Speaker 1: for that one operational. I mean, if it works, then

371
00:17:59,320 --> 00:18:03,200
Speaker 1: God bless him. But I have my doubts. Yeah, well,

372
00:18:03,520 --> 00:18:06,159
Speaker 1: so I'm just saying I'm not going to do it.

373
00:18:06,200 --> 00:18:07,760
Speaker 1: I'm not going to cut my hand off, just in

374
00:18:07,760 --> 00:18:10,840
Speaker 1: case you're wondering. I wasn't. Well, because you need him

375
00:18:10,880 --> 00:18:12,960
Speaker 1: for typing all of this, I do. Yeah, but of

376
00:18:13,000 --> 00:18:16,199
Speaker 1: course you could. You could type with your new prosthetic device.

377
00:18:16,320 --> 00:18:19,520
Speaker 1: So yeah, I'm thing to be like a hunting packs.

378
00:18:19,520 --> 00:18:21,720
Speaker 1: It would just be like one finger you hunting packed.

379
00:18:22,280 --> 00:18:26,359
Speaker 1: Oh lord, that's so slow, I wandered producer Jerry huntson

380
00:18:26,440 --> 00:18:31,639
Speaker 1: Packs producer Jerry. Oh, producer, Jerry, you said pretty Sue, Jerry,

381
00:18:31,800 --> 00:18:36,320
Speaker 1: Like pretty ser Jerry, You've just forgotten about it because

382
00:18:36,320 --> 00:18:38,280
Speaker 1: we can't see her anymore. It still sounds like you said,

383
00:18:38,320 --> 00:18:41,080
Speaker 1: it's the new headphones. I'm hearing pretty Sue Jerry. Well,

384
00:18:41,240 --> 00:18:45,560
Speaker 1: it sounds kind of like a pimp or something, you know. Yeah,

385
00:18:45,760 --> 00:18:48,359
Speaker 1: so listen, if you're not going to get a prosthetic limb,

386
00:18:48,400 --> 00:18:50,679
Speaker 1: you could always get a hand transplant. Would you be

387
00:18:50,720 --> 00:18:54,080
Speaker 1: interested in one of these? Um? Yeah, I was missing

388
00:18:54,080 --> 00:18:55,879
Speaker 1: a hand and someone was like, we can give you

389
00:18:55,920 --> 00:18:58,840
Speaker 1: another hand. Then I would what would you choose, Which

390
00:18:58,840 --> 00:19:02,280
Speaker 1: would you choose fetic in a real hand, My current

391
00:19:02,320 --> 00:19:04,720
Speaker 1: self would choose a real hand, my like ten year

392
00:19:04,720 --> 00:19:07,800
Speaker 1: old self, which is like a robotic hand with lasers.

393
00:19:07,920 --> 00:19:09,600
Speaker 1: So you might be interested to know a little bit

394
00:19:09,640 --> 00:19:12,240
Speaker 1: about the current state of hand transplants. And I learned

395
00:19:12,240 --> 00:19:15,720
Speaker 1: about them courtesy of Emory Healthcare, which is here in Atlanta.

396
00:19:16,080 --> 00:19:21,000
Speaker 1: So the technical name is composite tissue allow transplantation, and

397
00:19:21,040 --> 00:19:23,840
Speaker 1: that just means the transplantation of limbs and other intact

398
00:19:23,880 --> 00:19:26,479
Speaker 1: body parts. And this is a really complicated process, right,

399
00:19:26,480 --> 00:19:30,000
Speaker 1: because there's a lot of stuff to reattach right right,

400
00:19:30,040 --> 00:19:32,080
Speaker 1: I mean you're talking about bits of bone that may

401
00:19:32,080 --> 00:19:34,240
Speaker 1: have been shattered. You're talking about connective tissue that's not

402
00:19:34,280 --> 00:19:37,080
Speaker 1: in good shape. Maybe it's kind of mangled. Um, So

403
00:19:37,119 --> 00:19:39,359
Speaker 1: it's yeah, it is extremely complicated, and it can be

404
00:19:39,440 --> 00:19:42,200
Speaker 1: a really long surgery. And then perhaps you may have

405
00:19:42,240 --> 00:19:44,600
Speaker 1: to deal with immunosuppressive issues, and so you're gonna be

406
00:19:44,600 --> 00:19:47,440
Speaker 1: on immuno suppressive medication. I shouldn't say perhaps you will

407
00:19:47,520 --> 00:19:52,240
Speaker 1: be on immuno suppressive medication. Yeah, the first hand transplant

408
00:19:52,240 --> 00:19:55,840
Speaker 1: was performed back in nine in Ecuador, again to a sailor.

409
00:19:56,240 --> 00:19:58,240
Speaker 1: Sailor got the transplant and you had to have it

410
00:19:58,280 --> 00:20:01,520
Speaker 1: amputated two weeks after surgery because you know, his his

411
00:20:01,560 --> 00:20:04,720
Speaker 1: body rejected it. And then the next hand transplant was

412
00:20:04,720 --> 00:20:07,760
Speaker 1: performed in France in n And I'm wondering a little

413
00:20:07,760 --> 00:20:10,720
Speaker 1: bit from this research if France isn't kind of interested

414
00:20:10,760 --> 00:20:13,480
Speaker 1: in this whole transplant sphere because they were also the

415
00:20:13,480 --> 00:20:17,360
Speaker 1: folks who did the face transplant. Member. Yeah. Yeah, they're

416
00:20:17,359 --> 00:20:19,239
Speaker 1: making they're making leaps and bounds over there. I mean,

417
00:20:19,280 --> 00:20:22,280
Speaker 1: it's it's all I think, just awesome. I mean, I

418
00:20:22,840 --> 00:20:24,719
Speaker 1: just love the idea that, you know, someone if they

419
00:20:24,760 --> 00:20:26,840
Speaker 1: lose something like that, they would be able to get

420
00:20:26,840 --> 00:20:29,280
Speaker 1: it back or at least get you know, something back

421
00:20:29,359 --> 00:20:34,000
Speaker 1: that's made of flesh and not plastic, right, right, although

422
00:20:34,000 --> 00:20:38,400
Speaker 1: there are some good plastic options out there, totally right. So, um,

423
00:20:38,440 --> 00:20:41,080
Speaker 1: a couple of other interesting transplants that have occurred. There

424
00:20:41,119 --> 00:20:45,480
Speaker 1: was a uterus transplant, yeah, a couple of transplants involving knees,

425
00:20:45,960 --> 00:20:49,520
Speaker 1: and there was one that even involved a trichia. Yeah. Yeah, Well,

426
00:20:49,520 --> 00:20:53,000
Speaker 1: I have an interesting prosthetic You may remember this, but

427
00:20:53,320 --> 00:20:56,720
Speaker 1: an Ignoble Prize was awarded to an effort to create

428
00:20:56,760 --> 00:21:01,960
Speaker 1: prosthetic testicles for dogs. I forgot about that, right, so

429
00:21:02,080 --> 00:21:05,439
Speaker 1: they could be imbued with ERA. Yeah, which again this

430
00:21:05,520 --> 00:21:07,159
Speaker 1: is like back to the whole thing that dogs are

431
00:21:07,160 --> 00:21:08,560
Speaker 1: fine if they lose a leg, and if you can

432
00:21:08,600 --> 00:21:11,879
Speaker 1: get a dog neuter like you should, um, then dog's

433
00:21:11,960 --> 00:21:13,720
Speaker 1: gonna be all right, you know, Dog's not you know,

434
00:21:13,800 --> 00:21:16,000
Speaker 1: this is all the owner like thinking, oh, my dog

435
00:21:16,040 --> 00:21:18,359
Speaker 1: doesn't have testicles? How can I live with this? You know?

436
00:21:18,440 --> 00:21:22,480
Speaker 1: And and that's why I want an Ignoble Prize because

437
00:21:22,480 --> 00:21:24,880
Speaker 1: it's just like why why are you even wondering? Why

438
00:21:24,880 --> 00:21:26,479
Speaker 1: are you even coming up with this? You know, Well,

439
00:21:26,640 --> 00:21:28,399
Speaker 1: surely if they can have kitty wigs, they can have

440
00:21:28,440 --> 00:21:33,120
Speaker 1: a set of fake a dog. And if a Ford

441
00:21:33,160 --> 00:21:36,160
Speaker 1: truck can have them, then certainly the genuine articles should

442
00:21:36,160 --> 00:21:38,600
Speaker 1: be able to come back as well, right right, So

443
00:21:38,680 --> 00:21:40,680
Speaker 1: I think that about raps it up for deep dive

444
00:21:40,720 --> 00:21:43,840
Speaker 1: into prosthetic devices today, and we hope you've got an interesting,

445
00:21:43,920 --> 00:21:45,280
Speaker 1: not as deep a dive as you can get on

446
00:21:45,280 --> 00:21:47,720
Speaker 1: the website. Be sure to check out our article about

447

Speaker 1: and you'll get a couple of different things on the

450
00:21:55,680 --> 00:21:58,920
Speaker 1: house Stuff Works website about this kind of technology. Yeah yeah,

451
00:21:59,760 --> 00:22:06,280
Speaker 1: so listener Millan want to share today, all right, So

00:22:31,119 --> 00:22:33,880
Speaker 1: so well this is true for Pooh, it's worth noting

460
00:22:33,920 --> 00:22:36,520
Speaker 1: that urine is actually a great additive for composts. So

461
00:22:36,600 --> 00:22:40,520
Speaker 1: he goes on to expol the benefits of all that nitrogen,

462
00:22:42,000 --> 00:22:45,359
Speaker 1: and he writes, it's probably easier for the gentleman composters

463
00:22:45,400 --> 00:22:48,600
Speaker 1: out there to p into the compost than it is

464
00:22:48,640 --> 00:22:50,080
Speaker 1: for the ladies, and of course you need a certain

465
00:22:50,080 --> 00:22:52,200
Speaker 1: amount of privacy in your ear to make it happen.

466
00:22:52,320 --> 00:22:55,040
Speaker 1: Good point, Eric, and your neighbors will also probably be

467
00:22:55,040 --> 00:22:57,919
Speaker 1: happier if you don't vail your secret compost ingredient when

468
00:22:57,960 --> 00:23:00,960
Speaker 1: you start sharing the produce from your veggie garden. Indeed,

469
00:23:01,840 --> 00:23:04,720
Speaker 1: and lastly, Eric says, however, you may want to avoid

470
00:23:04,720 --> 00:23:08,600
Speaker 1: this technique if you're composting in the kitchen. Again, good point, Eric.

471
00:23:08,720 --> 00:23:11,120
Speaker 1: We thank you for that and your insight into the

472
00:23:11,119 --> 00:23:13,200
Speaker 1: the com posting matter. And we also had a good

473
00:23:13,200 --> 00:23:17,840
Speaker 1: one from Arizona Andrew in Arizona, Andrew writes that he

474
00:23:17,880 --> 00:23:20,119
Speaker 1: works for caterine company and he has a ton of

475
00:23:20,119 --> 00:23:22,280
Speaker 1: food that would otherwise be thrown in the trash. Now

476
00:23:22,320 --> 00:23:24,400
Speaker 1: I take it home and make a lovely, lovely soil

477
00:23:24,480 --> 00:23:27,080
Speaker 1: from it. And he also attached a picture of his

478
00:23:27,119 --> 00:23:30,920
Speaker 1: seven year ards on Brady, which I thought so adorable. Photos.

479
00:23:31,200 --> 00:23:33,960
Speaker 1: Yeah uh. And he writes, thanks for podcast. The kids

480
00:23:33,960 --> 00:23:36,199
Speaker 1: and I love listening. Well, we love you writing, so

481
00:23:36,240 --> 00:23:39,440
Speaker 1: thanks Andrew. In one last correction from Gary, we can

482
00:23:39,480 --> 00:23:42,119
Speaker 1: just call him Galaxy Gary, because Gary writes that I

483
00:23:42,119 --> 00:23:43,840
Speaker 1: want to remind you that the galaxy is the large

484
00:23:43,960 --> 00:23:46,800
Speaker 1: is not the largest structure in the universe. Uh. In fact,

485
00:23:46,880 --> 00:23:49,119
Speaker 1: galaxies are part of galaxy clusters, which are made up

486
00:23:49,119 --> 00:23:52,080
Speaker 1: of many galaxies that are gravitationally related to one another.

487
00:23:52,400 --> 00:23:56,000
Speaker 1: Thank you Gary, and we we discussed galaxies and galaxy

488
00:23:56,000 --> 00:24:00,840
Speaker 1: clusters in our podcast about how Galaxies Are World and
