00:00:03,120 --> 00:00:06,000
Speaker 1: Welcome to Stuff to Blow your Mind from how Stuff

2
00:00:06,000 --> 00:00:14,800
Speaker 1: Works dot com. Hey, welcome to Stuff to Blow your Mind.

3
00:00:14,840 --> 00:00:17,880
Speaker 1: My name is Robert lamb Man. I'm Julie Righty Douglas.

4
00:00:17,920 --> 00:00:19,680
Speaker 1: That's right. I'm right handed as well. This is a

5
00:00:19,800 --> 00:00:23,680
Speaker 1: right handed podcast. Now, technically Noel, who records this is

6
00:00:23,800 --> 00:00:26,560
Speaker 1: left handed, but this is a right handed podcast, so

7
00:00:26,600 --> 00:00:28,760
Speaker 1: we forced him to use his only his right hand

8
00:00:29,080 --> 00:00:30,960
Speaker 1: and left is down behind him at all times, at

9
00:00:31,040 --> 00:00:32,640
Speaker 1: least when he's recording us. I don't care what that

10
00:00:32,640 --> 00:00:36,640
Speaker 1: other podcasts do, but darnet, we have standards here. We do. Yeah,

11
00:00:36,760 --> 00:00:39,920
Speaker 1: we're keeping it right and tight all the time. Yeah,

12
00:00:39,960 --> 00:00:44,160
Speaker 1: because what we're firm believers that left handed individuals are debased,

13
00:00:44,240 --> 00:00:47,639
Speaker 1: their evil to freaks of nature, and they should be

14
00:00:48,200 --> 00:00:51,960
Speaker 1: distrusted at least and re educated along the right path

15
00:00:52,360 --> 00:00:55,160
Speaker 1: whenever possible. I mean, that's why we have the rule

16
00:00:55,440 --> 00:00:58,560
Speaker 1: of left hand behind the back in the podcast booth.

17
00:00:58,720 --> 00:01:01,480
Speaker 1: I mean, my wife is was born left handed. She's

18
00:01:01,560 --> 00:01:04,040
Speaker 1: right handed now because we have that corrected, and and

19
00:01:04,080 --> 00:01:05,880
Speaker 1: I love her, but I love her because you know,

20
00:01:05,920 --> 00:01:08,319
Speaker 1: we corrected what was wrong with it. Yeah. Well, you

21
00:01:08,319 --> 00:01:10,840
Speaker 1: know my husband is left handed, and uh, every once

22
00:01:10,840 --> 00:01:12,600
Speaker 1: in a while, I will catch him using it. And

23
00:01:12,640 --> 00:01:15,840
Speaker 1: our daughter's ambidextrous, and that's frowned upond as well. Yeah,

24
00:01:16,080 --> 00:01:17,800
Speaker 1: well but that can be that can be fixed over time.

25
00:01:17,880 --> 00:01:22,000
Speaker 1: We're trying, we're trying to firm with the discipline on

26
00:01:22,160 --> 00:01:23,840
Speaker 1: everybody in your life that is tempted to use their

27
00:01:23,880 --> 00:01:26,920
Speaker 1: left hand for for anything important. Yeah, so keep that

28
00:01:26,959 --> 00:01:28,679
Speaker 1: in mind as you guys are listening, whether or not

29
00:01:28,720 --> 00:01:32,240
Speaker 1: you're a righty or a lefty. Yes, it can be corrected. Now.

30
00:01:32,240 --> 00:01:34,240
Speaker 1: Of course, we're having a little fun here with with

31
00:01:34,280 --> 00:01:36,720
Speaker 1: our lefties, because of course there are all sorts of

32
00:01:36,760 --> 00:01:40,240
Speaker 1: stories about the left. Left handedness signifies evil, and left

33
00:01:40,240 --> 00:01:43,560
Speaker 1: handedness is wrong. And certainly we have created a right

34
00:01:43,600 --> 00:01:47,320
Speaker 1: handed world because the vast majority of individuals are right handed.

35
00:01:47,360 --> 00:01:50,720
Speaker 1: Only ten percent of the population is actually left handed.

36
00:01:51,080 --> 00:01:53,400
Speaker 1: And and and in reality, there's nothing evil about you guys.

37
00:01:53,400 --> 00:01:55,440
Speaker 1: But I love poking fun because everyone knows that this

38
00:01:55,520 --> 00:01:57,920
Speaker 1: is not true. But but when you when you start

39
00:01:57,920 --> 00:02:02,400
Speaker 1: prodding and poking the left andy's about this, they sometimes

40
00:02:02,400 --> 00:02:04,200
Speaker 1: get a little up in arms. Well it's true, because

41
00:02:04,200 --> 00:02:07,040
Speaker 1: I mean, think about it, you're pretty much outnumbered everybody

42
00:02:07,080 --> 00:02:10,040
Speaker 1: else using it right hand you're forced to use the

43
00:02:10,440 --> 00:02:14,280
Speaker 1: scissors that are awkward and bunched up, and all sorts

44
00:02:14,320 --> 00:02:16,839
Speaker 1: of different ways that you're navigating the world in which

45
00:02:16,880 --> 00:02:20,480
Speaker 1: you have to try to fit in to this right

46
00:02:20,520 --> 00:02:23,200
Speaker 1: hand world. Yeah. But but as we'll discuss in this episode,

47
00:02:23,680 --> 00:02:27,520
Speaker 1: left handedness brings with it its share of benefits in

48
00:02:27,520 --> 00:02:29,920
Speaker 1: addition to its many curses. Now, you guys might have

49
00:02:29,960 --> 00:02:34,919
Speaker 1: the upper advantage. Actually, yeah, certainly literally the upper hand,

50
00:02:35,040 --> 00:02:39,120
Speaker 1: the upper left hand advantage. Um. So, by the way,

51
00:02:39,200 --> 00:02:41,919
Speaker 1: I wanted to point out that you guys have been

52
00:02:42,080 --> 00:02:45,320
Speaker 1: ten percent of the population for a really, really long time.

53
00:02:45,360 --> 00:02:47,720
Speaker 1: And this is according to Perry Class, writing for the

54
00:02:47,760 --> 00:02:51,079
Speaker 1: New York Times, the size of the South Paw population

55
00:02:51,400 --> 00:02:54,840
Speaker 1: has held constant ever since hunter gatherer days. And this

56
00:02:54,880 --> 00:02:57,760
Speaker 1: is data that comes from studies of cave paintings and

57
00:02:58,000 --> 00:03:01,960
Speaker 1: archaeological analysis of ancient artifacts and how they were used.

58
00:03:02,560 --> 00:03:05,160
Speaker 1: So we know that for what at least ten fifteen

59
00:03:05,200 --> 00:03:08,320
Speaker 1: thousand years at the very least, that this has been

60
00:03:08,360 --> 00:03:11,720
Speaker 1: going on. Of course, you know, the human species extents

61
00:03:11,720 --> 00:03:14,880
Speaker 1: well beyond that. But right now we know you guys

62
00:03:14,880 --> 00:03:17,880
Speaker 1: have been the minority for a while. Now. It is interesting,

63
00:03:17,919 --> 00:03:20,480
Speaker 1: and we'll discuss the reason for this shortly, in some

64
00:03:20,560 --> 00:03:23,040
Speaker 1: areas where it's particularly a war torn where there's a

65
00:03:23,120 --> 00:03:26,120
Speaker 1: lot of violence going on, you'll sometimes see that the

66
00:03:26,160 --> 00:03:30,640
Speaker 1: number of left handed individuals increase. And this is this

67
00:03:30,760 --> 00:03:33,240
Speaker 1: is due not to the fact that left hand needs

68
00:03:33,320 --> 00:03:35,160
Speaker 1: are evil and then if there are more in an area,

69
00:03:35,160 --> 00:03:37,560
Speaker 1: it makes that area more prone to violence. But it

70
00:03:37,560 --> 00:03:41,920
Speaker 1: comes down to having a left handed advantage, supposedly in combat,

71
00:03:42,160 --> 00:03:43,920
Speaker 1: and we'll talk about that. We'll talk about why being

72
00:03:44,040 --> 00:03:47,760
Speaker 1: left handed is actually an advantage um not just in

73
00:03:47,760 --> 00:03:51,640
Speaker 1: in uh cognition, but also in warfare and other sports.

74
00:03:52,720 --> 00:03:55,280
Speaker 1: According to a two thousand and eight study, a meta

75
00:03:55,360 --> 00:03:59,080
Speaker 1: analysis of one forty four studies, that's a lot which

76
00:03:59,120 --> 00:04:01,520
Speaker 1: included one point so than million people. It's a lot

77
00:04:01,560 --> 00:04:05,080
Speaker 1: of people. To men have one point two three times

78
00:04:05,280 --> 00:04:08,400
Speaker 1: the odds of being left handed compared to win the chances.

79
00:04:08,440 --> 00:04:10,880
Speaker 1: So if you are a lefty woman and you're super

80
00:04:11,080 --> 00:04:14,120
Speaker 1: in the minority, which is weird because it seems like

81
00:04:14,160 --> 00:04:17,360
Speaker 1: I'm around a lot of left handed ladies, Like my

82
00:04:17,400 --> 00:04:19,719
Speaker 1: wife is left handed, my sister is left handed, and

83
00:04:19,800 --> 00:04:22,800
Speaker 1: we have at least a couple of lefty ladies here

84
00:04:22,839 --> 00:04:26,240
Speaker 1: in the office. It's true, you should probably examine. I'm

85
00:04:26,279 --> 00:04:28,479
Speaker 1: not going to out them, really, I don't know to

86
00:04:28,480 --> 00:04:31,360
Speaker 1: what extent there. Well, I think they're proud, Are they proudly? Yeah,

87
00:04:31,520 --> 00:04:34,080
Speaker 1: lefties tend to be proud these days. And then well

88
00:04:34,120 --> 00:04:37,960
Speaker 1: they should be Alison labor Milk, Christine Conder. Yeah, it's

89
00:04:37,960 --> 00:04:39,520
Speaker 1: not gonna be like they can hide it because you're

90
00:04:39,560 --> 00:04:41,080
Speaker 1: inevitably gonna have to go to a dinner and you're

91
00:04:41,080 --> 00:04:43,320
Speaker 1: gonna be bumping elbows with the right. Yeah, that's my

92
00:04:43,400 --> 00:04:46,040
Speaker 1: chief complaint. I have to say with my husband, we

93
00:04:46,080 --> 00:04:48,120
Speaker 1: always have to make sure we're in the right position

94
00:04:48,400 --> 00:04:54,280
Speaker 1: eating dinner position, that's right. See, mother's over forty are

95
00:04:54,400 --> 00:04:58,520
Speaker 1: one percent more likely to give birth to a lefty

96
00:04:58,720 --> 00:05:02,040
Speaker 1: than younger mom in their twenties, and only about one

97
00:05:02,080 --> 00:05:05,400
Speaker 1: percent of the population is truly ambidextrous. And this is

98
00:05:05,400 --> 00:05:08,680
Speaker 1: according to Live Sciences article south Paw Stats. Now, when

99
00:05:08,680 --> 00:05:11,320
Speaker 1: they say truly ambidextrous, what we're talking about here is

100
00:05:11,360 --> 00:05:15,360
Speaker 1: that there's a kind of spectrum of handedness, and so

101
00:05:15,560 --> 00:05:17,960
Speaker 1: people may be a little bit left handed or very

102
00:05:18,080 --> 00:05:20,799
Speaker 1: left handed on the spectrum, and it kind of reminds

103
00:05:20,800 --> 00:05:25,760
Speaker 1: me of the Kinsey Scale of sexuality. People heavily identify

104
00:05:26,680 --> 00:05:32,400
Speaker 1: as homosexual orsexual. There's a lot of room in between.

105
00:05:32,440 --> 00:05:34,880
Speaker 1: There's a sliding scale, and you're not necessarily going to

106
00:05:34,920 --> 00:05:37,480
Speaker 1: be one extreme or the other, but somewhere on that scale.

107
00:05:37,520 --> 00:05:40,040
Speaker 1: And the same host for left handedness and and the

108
00:05:40,160 --> 00:05:43,400
Speaker 1: and uh and behmbidextrous. That's true. All right, Let's talk

109
00:05:43,440 --> 00:05:46,599
Speaker 1: about genetics, because lefties, I feel like are often given

110
00:05:46,640 --> 00:05:50,120
Speaker 1: really short shrift in this area because there's an association

111
00:05:50,200 --> 00:05:53,640
Speaker 1: of increased cases of schizophrenia a d D and dyslexia

112
00:05:54,120 --> 00:05:56,480
Speaker 1: with left handedness. Yeah, and a lot of this comes

113
00:05:56,520 --> 00:05:58,920
Speaker 1: down to l r r t M one. That's the

114
00:05:59,000 --> 00:06:02,160
Speaker 1: specific gaine that's passed on from the father that tends

115
00:06:02,200 --> 00:06:04,960
Speaker 1: to increase the chances of someone being left handed, and

116
00:06:05,360 --> 00:06:08,160
Speaker 1: the same gene seems to confer slightly increased chance of

117
00:06:08,279 --> 00:06:12,000
Speaker 1: schizophrenia slightly slightly. Yeah. And by the way, this was

118
00:06:12,040 --> 00:06:13,880
Speaker 1: a study on dyslexic children, so I thought that was

119
00:06:13,960 --> 00:06:16,279
Speaker 1: kind of interesting. They weren't necessarily going after and trying

120
00:06:16,320 --> 00:06:19,360
Speaker 1: to figure out an association with it. It wasn't funded

121
00:06:19,440 --> 00:06:23,480
Speaker 1: by the by the the lefty support organizations or the

122
00:06:24,080 --> 00:06:27,279
Speaker 1: or the righty power organizations. That's right, wasn't funded by

123
00:06:27,320 --> 00:06:31,400
Speaker 1: the right. Um, So you have something called dextral or

124
00:06:31,600 --> 00:06:34,800
Speaker 1: chance genes. And according to Claire poor Act she's a

125
00:06:34,839 --> 00:06:38,680
Speaker 1: professor of psychology at Penn State Theory, humans are born

126
00:06:38,760 --> 00:06:41,680
Speaker 1: with two genes for handedness. So you either have dexterral

127
00:06:42,160 --> 00:06:45,960
Speaker 1: or chance, and the dominant dextral gene induces right handedness

128
00:06:46,279 --> 00:06:48,840
Speaker 1: whenever it turns up. But if there are two pairs

129
00:06:48,920 --> 00:06:51,200
Speaker 1: of chance genes, then that is when you become more

130
00:06:51,279 --> 00:06:55,000
Speaker 1: prone to becoming a lefty. Now, all of this being said,

131
00:06:55,760 --> 00:06:58,400
Speaker 1: there is an environmental factor here as well, so it's

132
00:06:58,400 --> 00:07:01,960
Speaker 1: not just coming down to janea um. Consider that identical

133
00:07:02,040 --> 00:07:04,960
Speaker 1: twins often have dominant hands, and this is according to

134
00:07:05,040 --> 00:07:08,840
Speaker 1: a Violin Lorens and evolutionary biologists. So even twins could

135
00:07:08,880 --> 00:07:11,360
Speaker 1: be differently handed, which makes sense because one can be

136
00:07:11,520 --> 00:07:13,920
Speaker 1: like the reflection of the other, right ones, the evil

137
00:07:13,960 --> 00:07:17,239
Speaker 1: twin once the good twins exact. Right, Well, I'm wonder

138
00:07:17,280 --> 00:07:20,560
Speaker 1: which one is the evil one? Now this is interesting, uh,

139
00:07:20,840 --> 00:07:22,400
Speaker 1: and this one we can just getting out of the

140
00:07:22,400 --> 00:07:25,200
Speaker 1: schizophrenic area and into some of the positives. Lefties, they say,

141
00:07:25,240 --> 00:07:27,560
Speaker 1: tend to have a more balanced view of their bodies,

142
00:07:28,440 --> 00:07:30,760
Speaker 1: and that's because when asked to the angel visualized space.

143
00:07:31,400 --> 00:07:34,320
Speaker 1: A righty tends to be more sensitive to their right side,

144
00:07:34,840 --> 00:07:36,920
Speaker 1: uh and their left side is more like a like

145
00:07:37,000 --> 00:07:40,120
Speaker 1: a t rex little arm, you know, so like imagine,

146
00:07:40,200 --> 00:07:42,240
Speaker 1: you know, we've all seen the homunculous, not the real

147
00:07:42,320 --> 00:07:45,200
Speaker 1: homunculous that a wizard bruise up, but the one that

148
00:07:45,480 --> 00:07:49,120
Speaker 1: represents our body image in our sense organs and and

149
00:07:49,480 --> 00:07:53,520
Speaker 1: and basically the shape of our body as as internalized

150
00:07:53,560 --> 00:07:56,920
Speaker 1: and sense. Like if we were to look at the

151
00:07:56,960 --> 00:08:01,080
Speaker 1: way a righty views their body, it would be, you know,

152
00:08:01,120 --> 00:08:03,920
Speaker 1: a very right hand dominated like a giant right right

153
00:08:04,080 --> 00:08:06,480
Speaker 1: arm and then like a tiny left arm, like they're

154
00:08:06,640 --> 00:08:10,840
Speaker 1: very very lopsided, whereas a lefty tends to uh not

155
00:08:11,000 --> 00:08:12,600
Speaker 1: have that kind of bias. And this comes from a

156
00:08:12,720 --> 00:08:15,520
Speaker 1: lifetime of having to deal with all the right handed

157
00:08:15,520 --> 00:08:18,000
Speaker 1: stuff in our world. So they're having to deal with

158
00:08:18,080 --> 00:08:21,080
Speaker 1: all of this right handed stuff, but they're actually left handed,

159
00:08:21,280 --> 00:08:23,440
Speaker 1: so the to kind of cancel each other out and

160
00:08:23,720 --> 00:08:26,800
Speaker 1: right the ship right, and which makes it makes sense

161
00:08:26,840 --> 00:08:30,880
Speaker 1: that there's more spatial awareness and could possibly be one

162
00:08:30,920 --> 00:08:33,000
Speaker 1: of the reasons why a lot of lefties tend to

163
00:08:33,080 --> 00:08:35,679
Speaker 1: be engineers, because there are people who can deal with

164
00:08:35,720 --> 00:08:38,760
Speaker 1: spatial reasoning really really well. Um, and a lot of

165
00:08:38,840 --> 00:08:41,679
Speaker 1: this has to do not just with spacial reasoning, but

166
00:08:41,920 --> 00:08:46,880
Speaker 1: just your processing your motor skills, also language processing. But

167
00:08:47,080 --> 00:08:49,679
Speaker 1: going back to motor skills, just wanted to lay out

168
00:08:49,720 --> 00:08:52,839
Speaker 1: there that the nerves connect our hands to the areas

169
00:08:52,880 --> 00:08:55,880
Speaker 1: of the brain responsible for motor skills. So there's a

170
00:08:55,920 --> 00:08:59,319
Speaker 1: separate set for each hand, but the wiring is crossed,

171
00:08:59,559 --> 00:09:01,240
Speaker 1: so you're right hand is hooked up to the left

172
00:09:01,280 --> 00:09:03,640
Speaker 1: side of the brain and vice versa. But when you

173
00:09:03,720 --> 00:09:07,120
Speaker 1: look at left east, they're taking in data and they're

174
00:09:07,160 --> 00:09:10,720
Speaker 1: they're really bi cerebral if you think about it, because

175
00:09:10,840 --> 00:09:15,840
Speaker 1: they are factoring in particularly language in both hemispheres, whereas

176
00:09:15,960 --> 00:09:19,319
Speaker 1: right eas are processing language in the left hemisphere. So

177
00:09:19,400 --> 00:09:21,440
Speaker 1: as a result of the corpus close and we've talked

178
00:09:21,440 --> 00:09:23,439
Speaker 1: about this this little guy before, it's a part of

179
00:09:23,440 --> 00:09:27,679
Speaker 1: that connects to both hemispheres. Is about eleven larger and

180
00:09:27,800 --> 00:09:30,520
Speaker 1: left handed brains than right handed brains. And this is

181
00:09:30,600 --> 00:09:34,599
Speaker 1: this idea that it's actually aiding the left east to

182
00:09:34,720 --> 00:09:38,640
Speaker 1: be quicker on the uptake of information and processing it.

183
00:09:39,640 --> 00:09:41,000
Speaker 1: All Right, we're gonna take a break and when we

184
00:09:41,080 --> 00:09:44,040
Speaker 1: come back, we're gonna deal more with left handed individuals

185
00:09:44,200 --> 00:09:47,120
Speaker 1: about why you might want to think twice about getting

186
00:09:47,160 --> 00:09:59,120
Speaker 1: into it. It's fight with one all right, we're back.

187
00:09:59,360 --> 00:10:02,960
Speaker 1: We're talking about lefties. And if you engaged in sports

188
00:10:03,200 --> 00:10:06,360
Speaker 1: or fist fights, or sports and fist fights or fist

189
00:10:06,400 --> 00:10:09,079
Speaker 1: fights that are actually a form of sports, there's a

190
00:10:09,160 --> 00:10:11,040
Speaker 1: chance you're gonna come up against the lefty at some point.

191
00:10:11,240 --> 00:10:14,440
Speaker 1: They're only ten of the population. But when you start

192
00:10:14,520 --> 00:10:16,920
Speaker 1: looking at some of the big names in sports, you

193
00:10:16,960 --> 00:10:19,079
Speaker 1: look at Adam Palmer, you look at Bobby Or, you

194
00:10:19,120 --> 00:10:22,720
Speaker 1: look at John McEnroe, Oscar de la Hoya, and Babe Ruth.

195
00:10:23,120 --> 00:10:26,320
Speaker 1: Even though Babe Ruth supposedly wrote right handed, these were

196
00:10:26,400 --> 00:10:29,559
Speaker 1: all lefties. These were all people at the top of

197
00:10:29,679 --> 00:10:32,839
Speaker 1: their sport and they were doing it with the left hand. Yeah.

198
00:10:32,880 --> 00:10:35,679
Speaker 1: And as you had mentioned that lefties living in the

199
00:10:35,760 --> 00:10:38,679
Speaker 1: right hand world, they have much more spatial awareness on

200
00:10:38,760 --> 00:10:43,240
Speaker 1: both sides. Right And according to Melissa Rough in her

201
00:10:43,280 --> 00:10:46,199
Speaker 1: book The Left Stuff, bio mechanical research has revealed that

202
00:10:46,280 --> 00:10:48,600
Speaker 1: training the non dominant side of the body can actually

203
00:10:48,679 --> 00:10:50,679
Speaker 1: enhance the dominant side, and this is known as the

204
00:10:50,720 --> 00:10:54,359
Speaker 1: cross training effect, and the body's neural network is integrated

205
00:10:54,400 --> 00:10:58,040
Speaker 1: on both sides, which would confer an advantage already, right, right,

206
00:10:58,120 --> 00:11:01,120
Speaker 1: And then if you're you're training to do from you know,

207
00:11:01,200 --> 00:11:06,360
Speaker 1: to combat other individuals, say with swords, with with pointed sticks,

208
00:11:06,760 --> 00:11:08,839
Speaker 1: or in engaging to to fight against some in a

209
00:11:08,920 --> 00:11:12,160
Speaker 1: boxing match or in tennis, you're going to more likely

210
00:11:12,160 --> 00:11:16,640
Speaker 1: you're gonna train mostly to deal with the population, unless

211
00:11:16,640 --> 00:11:19,360
Speaker 1: you're you're saying I'm only going to box schizophrenics, in

212
00:11:19,440 --> 00:11:22,280
Speaker 1: which case you're gonna deal with of that population is

213
00:11:22,360 --> 00:11:26,280
Speaker 1: left handed. Actually due to the slightly higher chances that

214
00:11:26,400 --> 00:11:31,440
Speaker 1: we talked about earlier population of lefties. Yes, yes, yeah,

215
00:11:31,559 --> 00:11:35,240
Speaker 1: so most of your training is going to revolve around

216
00:11:35,360 --> 00:11:39,559
Speaker 1: fighting other rightings or even if you're a lefty, you're

217
00:11:39,559 --> 00:11:41,599
Speaker 1: going to be more predisposed to fight right eas But

218
00:11:41,640 --> 00:11:43,760
Speaker 1: then when you deal with a lefty, it's going to

219
00:11:43,840 --> 00:11:46,280
Speaker 1: potentially skew things just a little bit because their hand

220
00:11:46,360 --> 00:11:49,439
Speaker 1: dominance is gonna be gonna be different, uh there, and

221
00:11:49,679 --> 00:11:52,160
Speaker 1: their training is going to be different. It throws things

222
00:11:52,200 --> 00:11:54,000
Speaker 1: out of whack. And we see this in the natural

223
00:11:54,040 --> 00:11:58,240
Speaker 1: world too, right. We see this with sea snails that

224
00:11:58,400 --> 00:12:02,319
Speaker 1: actually the shape of their shell are coiled counter clockwise

225
00:12:02,559 --> 00:12:05,760
Speaker 1: or left as opposed to the more typical clockwise arrangement.

226
00:12:06,240 --> 00:12:10,520
Speaker 1: Now why is this useful, Well, it's because right claude

227
00:12:10,600 --> 00:12:13,760
Speaker 1: predator crabs are used to kind of can opening them

228
00:12:13,920 --> 00:12:16,640
Speaker 1: right with their with their claws, but they come upon

229
00:12:17,120 --> 00:12:20,040
Speaker 1: a sea snail who's a lefty with a counterclockwise swirl

230
00:12:21,000 --> 00:12:23,559
Speaker 1: or configuration to their shell and they can't get in

231
00:12:23,679 --> 00:12:26,240
Speaker 1: there and crack them open. Yeah, they have evolved to

232
00:12:26,360 --> 00:12:28,920
Speaker 1: eat right e's and then when a lefty presents itself,

233
00:12:29,400 --> 00:12:31,800
Speaker 1: they can't cope with it. They have their their form

234
00:12:32,120 --> 00:12:36,199
Speaker 1: is not suitable to this altered form. Would like a

235
00:12:36,360 --> 00:12:39,120
Speaker 1: righty in in the um the boxing match with the

236
00:12:39,240 --> 00:12:41,880
Speaker 1: lefty right exactly can't really anticipate how this is going

237
00:12:41,920 --> 00:12:44,960
Speaker 1: to play out. Yeah, now that's that's why a boxer

238
00:12:45,080 --> 00:12:47,360
Speaker 1: knows that he or she is going up against a lefty,

239
00:12:47,640 --> 00:12:51,079
Speaker 1: then they'll intensify their training, uh with a with a

240
00:12:51,200 --> 00:12:55,080
Speaker 1: left handed sparring partner, because because again the percentage is there.

241
00:12:55,200 --> 00:12:57,679
Speaker 1: You can't go if you're a professional boxer, if you're

242
00:12:57,679 --> 00:13:00,679
Speaker 1: a professional tennis player, if you're just they do with

243
00:13:00,720 --> 00:13:04,160
Speaker 1: a sword in a on a medieval battlefield, chances are

244
00:13:04,280 --> 00:13:06,920
Speaker 1: you're going to encounter that left handed individual at some point,

245
00:13:06,960 --> 00:13:08,960
Speaker 1: and you don't want to just be completely decimated by

246
00:13:09,000 --> 00:13:11,840
Speaker 1: then when it happens. But even that, even the training

247
00:13:12,240 --> 00:13:15,720
Speaker 1: is not going to give you the advantage that lefties

248
00:13:15,800 --> 00:13:19,480
Speaker 1: have with the processing right. With the cognitive processing, study

249
00:13:19,720 --> 00:13:24,000
Speaker 1: leader Dr Nick Turban from the Australian National University took

250
00:13:24,080 --> 00:13:27,400
Speaker 1: left handed and right handed people and recorded the transfer

251
00:13:27,480 --> 00:13:30,120
Speaker 1: time between the two sides of the brain. And he

252
00:13:30,240 --> 00:13:33,360
Speaker 1: did this through measuring reaction times, and reaction times being

253
00:13:33,480 --> 00:13:36,160
Speaker 1: huge in sports. UH two white dots flashed to the

254
00:13:36,240 --> 00:13:39,640
Speaker 1: left and right of a fixed cross configuration on their screen.

255
00:13:40,280 --> 00:13:43,080
Speaker 1: He compared this with how good participants were carrying out

256
00:13:43,160 --> 00:13:46,439
Speaker 1: the task to spot matching letters in the left and

257
00:13:46,520 --> 00:13:48,800
Speaker 1: right visual fields, which will require them to use the

258
00:13:49,080 --> 00:13:50,960
Speaker 1: same parts of the brain at the same time. Um

259
00:13:51,520 --> 00:13:55,360
Speaker 1: extreme left handed individuals, those people in the spectrum extreme

260
00:13:55,440 --> 00:13:59,959
Speaker 1: lefties were forty three milliseconds faster at spotting matching letters

261
00:14:00,000 --> 00:14:02,800
Speaker 1: across the right and left visual fields than their right

262
00:14:02,920 --> 00:14:07,920
Speaker 1: handed compatriots. So again you're talking about a more symetrical brain,

263
00:14:08,360 --> 00:14:13,840
Speaker 1: a larger corpus clos um transmitting that information. So even

264
00:14:13,920 --> 00:14:17,480
Speaker 1: if someone is swinging at you and you've trained against them, um,

265
00:14:17,600 --> 00:14:19,800
Speaker 1: and you swing against them, they're they're taking in the

266
00:14:20,120 --> 00:14:25,200
Speaker 1: data quicker than you are. Well. Um. I mentioned earlier

267
00:14:25,240 --> 00:14:28,920
Speaker 1: about how war torn areas you might see an increase

268
00:14:29,000 --> 00:14:31,200
Speaker 1: in the number of left handed individuals in your myths,

269
00:14:31,640 --> 00:14:34,440
Speaker 1: and this comes back to a study from Para French

270
00:14:34,480 --> 00:14:38,760
Speaker 1: researchers uh Charlotte Foi and Michael Raymond. This is between

271
00:14:38,800 --> 00:14:41,240
Speaker 1: two thousand and one and two thousand four. They tested

272
00:14:41,280 --> 00:14:44,400
Speaker 1: the theory of lefty battle supremacy by examining the prevalence

273
00:14:44,600 --> 00:14:47,320
Speaker 1: of left handed citizens in area with areas with high

274
00:14:47,480 --> 00:14:50,560
Speaker 1: murder rates, because in theory, these conditions would allow them

275
00:14:50,600 --> 00:14:53,600
Speaker 1: a better chance to observe at least statistically the left,

276
00:14:54,000 --> 00:14:56,880
Speaker 1: the lefty survival of the fist. And sure enough they

277
00:14:56,960 --> 00:15:01,880
Speaker 1: found that lefty population percentages in these areas win as

278
00:15:01,960 --> 00:15:05,560
Speaker 1: high as twenty seven percent, so again up from ten

279
00:15:05,600 --> 00:15:09,520
Speaker 1: percent of the population to because there's that much face

280
00:15:09,600 --> 00:15:13,360
Speaker 1: stabbing going on that the lefty face stabbers are going

281
00:15:13,480 --> 00:15:17,640
Speaker 1: to actually sustain their population, whereas the righties are going

282
00:15:17,720 --> 00:15:19,600
Speaker 1: to die of their face wins. Okay, so you have

283
00:15:19,880 --> 00:15:23,840
Speaker 1: some negative connotations of like schizophrenia, dyslexia, and so on

284
00:15:23,840 --> 00:15:26,760
Speaker 1: and so forth, but now you have criminality added to

285
00:15:27,400 --> 00:15:31,640
Speaker 1: It's just the culture itself is falling into criminality and

286
00:15:31,680 --> 00:15:34,440
Speaker 1: falling into violence. And you can't blame the lefties for

287
00:15:34,520 --> 00:15:37,080
Speaker 1: just being better at stabbing people in the face. That's

288
00:15:37,120 --> 00:15:41,120
Speaker 1: just that's just a fact, right, But an unintended consequence

289
00:15:41,240 --> 00:15:44,240
Speaker 1: might be that those lefties watch out, they're gonna shrank yea, yeah,

290
00:15:44,240 --> 00:15:47,560
Speaker 1: I mean its survival of the Fittestralia. Well, okay, so

291
00:15:47,840 --> 00:15:50,800
Speaker 1: that's playing to this idea though, that that lefties are

292
00:15:50,800 --> 00:15:54,080
Speaker 1: inherently sinister. Yeah, there's something off about them, that their

293
00:15:54,640 --> 00:15:57,360
Speaker 1: their skills seem a little better. And we can either

294
00:15:57,520 --> 00:15:59,880
Speaker 1: chalk that up to again the inner workings of their

295
00:16:00,080 --> 00:16:03,200
Speaker 1: rain and how they have to to to deal with

296
00:16:03,280 --> 00:16:05,240
Speaker 1: a righty world, or it could be that they have

297
00:16:05,320 --> 00:16:06,920
Speaker 1: a touch of the devil, as say, it was a

298
00:16:07,000 --> 00:16:09,920
Speaker 1: pact with the devil. Right. Um. We look at at

299
00:16:09,960 --> 00:16:13,120
Speaker 1: the left and the right in religious terms sometimes, and

300
00:16:13,240 --> 00:16:16,320
Speaker 1: this is because if you look at text, you'll see

301
00:16:16,840 --> 00:16:20,160
Speaker 1: that Jesus ascends to heaven on the right hand of God.

302
00:16:21,080 --> 00:16:25,000
Speaker 1: You have a virginal reference of descending into hell on

303
00:16:25,120 --> 00:16:29,800
Speaker 1: the left, and so you also have um. You have

304
00:16:30,000 --> 00:16:32,960
Speaker 1: also have it ingrained in language like an Italian, the

305
00:16:33,080 --> 00:16:38,320
Speaker 1: word for left is sinistra, which means sinister. So these

306
00:16:38,360 --> 00:16:41,560
Speaker 1: things are already at playing here for the giving us

307
00:16:41,880 --> 00:16:44,160
Speaker 1: this idea of how to proceed with lefties. And we

308
00:16:44,320 --> 00:16:48,320
Speaker 1: just did an episode on symbols and how that is

309
00:16:48,480 --> 00:16:50,840
Speaker 1: silently guiding us in the way that we perceived the

310
00:16:50,880 --> 00:16:54,240
Speaker 1: world around us. Yeah. In the English language, right means

311
00:16:54,360 --> 00:16:59,960
Speaker 1: both correct and right side. In our politics, left tends

312
00:17:00,040 --> 00:17:05,840
Speaker 1: to denote the more radical side, um, the more left

313
00:17:05,960 --> 00:17:10,000
Speaker 1: field right field versus right field. And and then you

314
00:17:10,040 --> 00:17:13,240
Speaker 1: have things like left handed compliments where it's a compliment,

315
00:17:13,320 --> 00:17:15,760
Speaker 1: but it's it's like a vile compliment that is meant

316
00:17:15,800 --> 00:17:18,960
Speaker 1: to to drive home some sort of an insult. And then,

317
00:17:19,000 --> 00:17:20,720
Speaker 1: of course, in various cultures, is also the idea that

318
00:17:20,800 --> 00:17:25,440
Speaker 1: the left hand is the wiping hand for the for

319
00:17:25,520 --> 00:17:28,200
Speaker 1: the pooh, and therefore to shake with the left hand

320
00:17:28,400 --> 00:17:30,720
Speaker 1: is is frowned upon, or to do anything with the

321
00:17:30,800 --> 00:17:34,480
Speaker 1: left hand. Okay, but what if what if the population

322
00:17:35,320 --> 00:17:38,440
Speaker 1: all of a sudden we're lefties, Well we'd have a

323
00:17:38,480 --> 00:17:40,320
Speaker 1: lot of stuff to change, right, I mean all the desks,

324
00:17:40,320 --> 00:17:42,840
Speaker 1: which because suddenly the lefties there, this would be their

325
00:17:42,880 --> 00:17:46,680
Speaker 1: dream scenario. Suddenly they're in charge, they would probably wipe

326
00:17:46,680 --> 00:17:49,440
Speaker 1: the rest of us out. It's true, Um, And I'm

327
00:17:49,560 --> 00:17:53,240
Speaker 1: just gonna predicate this on a study. It's a two

328
00:17:53,280 --> 00:17:57,320
Speaker 1: thousand eleven study published in Psychological Science by Daniel Kasanto.

329
00:17:57,880 --> 00:17:59,800
Speaker 1: And the idea is that you reverse the symbols of

330
00:18:00,040 --> 00:18:03,840
Speaker 1: and bad right and left. It's like, yes, it is

331
00:18:04,040 --> 00:18:06,080
Speaker 1: some some who have them and some who don't write

332
00:18:07,080 --> 00:18:10,159
Speaker 1: and uh, what they are doing is they're saying unconsciously,

333
00:18:10,359 --> 00:18:12,879
Speaker 1: right handers associate good with the right side of space

334
00:18:13,000 --> 00:18:15,119
Speaker 1: and bad with the left. Now, of course, people who

335
00:18:15,160 --> 00:18:18,159
Speaker 1: are left handed do not have the same association. They

336
00:18:18,240 --> 00:18:21,920
Speaker 1: think the left hand and the left spaces are perfectly fine.

337
00:18:22,680 --> 00:18:25,200
Speaker 1: This is what they found out when they messed with

338
00:18:25,520 --> 00:18:29,280
Speaker 1: hand dominance. And what they wanted to do first, though,

339
00:18:29,400 --> 00:18:32,000
Speaker 1: is they wanted to look at language and this idea

340
00:18:32,080 --> 00:18:35,840
Speaker 1: of positive things being associated with the right side. And

341
00:18:35,960 --> 00:18:39,000
Speaker 1: so to test this, they were asked, um, you know,

342
00:18:39,440 --> 00:18:42,680
Speaker 1: right hand participants were asked which of two products to buy,

343
00:18:43,080 --> 00:18:45,800
Speaker 1: which of two job applicants to hire, or which of

344
00:18:45,880 --> 00:18:50,040
Speaker 1: two alien creatures looks more intelligent? Um. Right handers tended

345
00:18:50,080 --> 00:18:52,680
Speaker 1: to choose the product, person, or creature they saw on

346
00:18:52,760 --> 00:18:56,400
Speaker 1: their right, and most left handers, most of them chose

347
00:18:56,440 --> 00:18:58,520
Speaker 1: the one on their left. Isn't that amazing that just

348
00:18:58,680 --> 00:19:02,119
Speaker 1: in this spacial confige duration you can put person to

349
00:19:02,160 --> 00:19:04,080
Speaker 1: a on the right, person be on the left, and

350
00:19:04,160 --> 00:19:06,480
Speaker 1: if you're right handed, you're you're more apt to hire

351
00:19:06,560 --> 00:19:09,960
Speaker 1: that person or to think that this person or creature,

352
00:19:10,119 --> 00:19:12,520
Speaker 1: alien creature, is more intelligent than one on the left.

353
00:19:13,080 --> 00:19:16,520
Speaker 1: And yet not to complicate via scenario that every time

354
00:19:16,560 --> 00:19:18,880
Speaker 1: we look in the mirror and we consider the person

355
00:19:19,119 --> 00:19:22,520
Speaker 1: most central to our view of the world, we're looking

356
00:19:22,640 --> 00:19:25,119
Speaker 1: at a we're looking at a reflection, we're looking at

357
00:19:25,119 --> 00:19:28,200
Speaker 1: a reversal. Um. But I think you're onto something. You're

358
00:19:28,520 --> 00:19:32,159
Speaker 1: about the correcting of right and left in terms of

359
00:19:32,280 --> 00:19:36,040
Speaker 1: their moral qualities, and about this this glove. Yeah, well

360
00:19:36,119 --> 00:19:39,800
Speaker 1: this glove. The researchers put this on the right handers

361
00:19:39,840 --> 00:19:42,639
Speaker 1: and the left handers, um, and they performed a motor

362
00:19:42,720 --> 00:19:46,639
Speaker 1: fluency task while wearing this really bulky glove, and it

363
00:19:46,840 --> 00:19:50,440
Speaker 1: turned these right handers in temporarily into left handers. And

364
00:19:50,520 --> 00:19:55,159
Speaker 1: about only twelve minutes of this lopsided motor experience, the

365
00:19:55,280 --> 00:19:59,600
Speaker 1: right glove participants judgments on an unrelated task showed a

366
00:19:59,760 --> 00:20:02,560
Speaker 1: good it is left bias like natural left handers do.

367
00:20:03,400 --> 00:20:05,680
Speaker 1: So it shows that you can just change up the

368
00:20:05,760 --> 00:20:12,000
Speaker 1: scenario and actually have the bodily experience change your psychological experience. Yeah.

369
00:20:12,040 --> 00:20:16,159
Speaker 1: So it's essentially Sylvester Monkey mcmonkey McBean's uh star on

370
00:20:16,359 --> 00:20:19,800
Speaker 1: or star off machine this glove actor SEUs Yeah, and

371
00:20:20,040 --> 00:20:23,440
Speaker 1: gazing into the future and considering this possibility of of

372
00:20:23,520 --> 00:20:28,879
Speaker 1: suddenly they're being lefties. I can imagine them rounding up

373
00:20:28,920 --> 00:20:31,359
Speaker 1: all the rights and making us wear those gloves so

374
00:20:31,480 --> 00:20:33,960
Speaker 1: that they can change the way that we view the world.

375
00:20:34,119 --> 00:20:35,520
Speaker 1: That might not be a bad thing, right, because did

376
00:20:35,560 --> 00:20:37,200
Speaker 1: you hear that all the time? Like you should change

377
00:20:37,440 --> 00:20:40,320
Speaker 1: the hand that you brush your teeth with because it's

378
00:20:40,359 --> 00:20:42,320
Speaker 1: good for the brains, good for the brain. Right, So

379
00:20:42,920 --> 00:20:45,320
Speaker 1: what if we decided all to do this? Is it possible?

380
00:20:45,800 --> 00:20:49,600
Speaker 1: What would happen if we changed our handedness? I think that,

381
00:20:49,640 --> 00:20:51,760
Speaker 1: I mean, it's worth worth drying. I want to do

382
00:20:51,880 --> 00:20:53,760
Speaker 1: more of it because I was trying to think on

383
00:20:53,880 --> 00:20:56,040
Speaker 1: the right end this morning. I was thinking, what do

384
00:20:56,119 --> 00:20:58,879
Speaker 1: I do with my left hand? Um, I if I

385
00:20:59,040 --> 00:21:01,520
Speaker 1: if my right hand is occupied, then I may use

386
00:21:01,600 --> 00:21:04,679
Speaker 1: my left hand to drink water or whatever or if

387
00:21:04,680 --> 00:21:07,400
Speaker 1: I'm on the train, I may read with my left

388
00:21:07,440 --> 00:21:10,040
Speaker 1: hand while I'm holding onto the bar with my right.

389
00:21:10,400 --> 00:21:11,680
Speaker 1: But for the most part of THO like, I don't

390
00:21:11,680 --> 00:21:14,919
Speaker 1: do enough with it outside of the manipulation of various

391
00:21:14,960 --> 00:21:18,520
Speaker 1: computer gadgets well. And as a result, actually your your

392
00:21:18,640 --> 00:21:23,119
Speaker 1: nerves are less developed. And that's that side of your hand,

393
00:21:23,200 --> 00:21:25,840
Speaker 1: by the way, um, because it takes a while if

394
00:21:25,880 --> 00:21:27,960
Speaker 1: you're going to switch hands to try to build up

395
00:21:28,040 --> 00:21:30,159
Speaker 1: his connections. It makes sense, right, because it's more of

396
00:21:30,200 --> 00:21:33,520
Speaker 1: a pathway that's being used. And people who have sustained

397
00:21:33,560 --> 00:21:35,560
Speaker 1: injuries now this and they're not able to use their

398
00:21:35,640 --> 00:21:39,440
Speaker 1: left hand. Um. Actually, according to poor act that she's

399
00:21:39,480 --> 00:21:41,680
Speaker 1: the professor of psychology that I had talked about before,

400
00:21:42,240 --> 00:21:44,600
Speaker 1: one student that she studied who had been in an

401
00:21:44,640 --> 00:21:48,000
Speaker 1: accident that permanently injured his dominant hand was able to

402
00:21:48,119 --> 00:21:50,920
Speaker 1: eat with a four and other basic activities work just fine,

403
00:21:51,119 --> 00:21:55,920
Speaker 1: but when it came to um cursive writing versus printing,

404
00:21:56,320 --> 00:21:58,840
Speaker 1: he had a lot of trouble. I mean, printing was fine,

405
00:21:59,400 --> 00:22:01,119
Speaker 1: but it turns out that when he was trying to

406
00:22:01,200 --> 00:22:03,280
Speaker 1: write in cursive it was a bit of a nightmare.

407
00:22:03,640 --> 00:22:08,080
Speaker 1: And that's because these two actions come from different regions

408
00:22:08,119 --> 00:22:09,800
Speaker 1: of the same part of the brain, and there's a

409
00:22:09,840 --> 00:22:13,359
Speaker 1: strip across the parietal lobe here. And handwriting is a

410
00:22:13,480 --> 00:22:17,199
Speaker 1: fine motor skill, while printing is not. So not everything

411
00:22:17,320 --> 00:22:20,679
Speaker 1: can be sort of perfect, even if you are building

412
00:22:20,760 --> 00:22:24,280
Speaker 1: up those neural connections in your non dominant hand. Well,

413
00:22:24,400 --> 00:22:26,359
Speaker 1: I was always a nightmare when I was trying to

414
00:22:26,440 --> 00:22:29,800
Speaker 1: do cursive weaven with my dominant hands. So you know,

415
00:22:29,960 --> 00:22:32,240
Speaker 1: I was writing a note to my daughter's teacher. For

416
00:22:32,320 --> 00:22:33,720
Speaker 1: some reason I did in cursive. I guess I was

417
00:22:33,760 --> 00:22:36,800
Speaker 1: trying to be fancy, and it was very hard because

418
00:22:36,920 --> 00:22:39,000
Speaker 1: you know, in this day and age, it's very seldom

419
00:22:39,040 --> 00:22:43,440
Speaker 1: that I actually write print anymore, let alone use cursive handwriting.

420
00:22:44,280 --> 00:22:46,840
Speaker 1: Kind of hurt my brain a bit, all right, So

421
00:22:46,880 --> 00:22:50,040
Speaker 1: I want to give you one more extreme example of

422
00:22:50,400 --> 00:22:55,119
Speaker 1: becoming a lefty, and um, this can be found. Actually,

423
00:22:55,200 --> 00:22:57,240
Speaker 1: the evidence of this can be found at the medieval

424
00:22:57,520 --> 00:23:01,680
Speaker 1: Fernie Hurst Castle in Scotland. Uh So, just consider this

425
00:23:01,760 --> 00:23:05,680
Speaker 1: fact that historically in castle's staircases are built so that

426
00:23:05,760 --> 00:23:08,119
Speaker 1: the defenders at the top have their sword free to

427
00:23:08,400 --> 00:23:12,280
Speaker 1: swing at opponents, while invaders have their swing impeded by

428
00:23:12,320 --> 00:23:14,600
Speaker 1: the wall, so they're thinking about this when they're building

429
00:23:14,640 --> 00:23:17,360
Speaker 1: the castle, like, how what's the advantage when I'm using

430
00:23:17,400 --> 00:23:19,000
Speaker 1: my sword at the top and I'm trying to defend.

431
00:23:19,920 --> 00:23:23,919
Speaker 1: According to Sally Lincoln Auger, she's a perceptual scientists at

432
00:23:23,920 --> 00:23:27,840
Speaker 1: the University of Virginia, the Warrior clan care at this

433
00:23:27,960 --> 00:23:30,400
Speaker 1: castle trained to use their weapons in their left hand,

434
00:23:30,840 --> 00:23:33,960
Speaker 1: and even fitted their castle with a staircase that's tricked

435
00:23:33,960 --> 00:23:36,600
Speaker 1: out just so that it could allow their left hands

436
00:23:36,680 --> 00:23:40,560
Speaker 1: to wield a sword at invaders. And the ancestors of

437
00:23:40,640 --> 00:23:43,600
Speaker 1: the clancare are all right dominant. So the idea here

438
00:23:43,800 --> 00:23:49,040
Speaker 1: is that they weren't all, you know, miraculously lefties. They

439
00:23:49,119 --> 00:23:52,800
Speaker 1: just knew that there was a lefty battle advantage, and

440
00:23:52,880 --> 00:23:56,240
Speaker 1: so they actually train themselves to take advantage of that

441
00:23:56,400 --> 00:23:58,399
Speaker 1: that advantage. Yeah, I thought that was pretty impressive. That

442
00:23:58,560 --> 00:24:01,080
Speaker 1: is all right, Well they you have it, um a

443
00:24:01,160 --> 00:24:03,479
Speaker 1: little insight into the world of lefties for you right

444
00:24:03,520 --> 00:24:07,120
Speaker 1: es and uh, a little more self knowledge for you lefties.

445
00:24:07,480 --> 00:24:10,640
Speaker 1: I already knew you were awesome, admitted. Yeah, they're they're

446
00:24:10,640 --> 00:24:15,719
Speaker 1: pretty rag out their their powers and and but but anyway,

447
00:24:15,760 --> 00:24:17,680
Speaker 1: we we love our lefties and our righty listeners. So

448
00:24:17,800 --> 00:24:19,399
Speaker 1: Please don't take anything I said at the top of

449
00:24:19,480 --> 00:24:22,879
Speaker 1: the podcast too heart. Just take the science that we

450
00:24:22,960 --> 00:24:25,320
Speaker 1: talked about too hard or to brain. Yeah, and by

451
00:24:25,359 --> 00:24:27,560
Speaker 1: the way, Noel's left hand is lifting a little bit

452
00:24:27,800 --> 00:24:29,600
Speaker 1: beat right and underneath all that, oh yeah, we need

453
00:24:29,680 --> 00:24:31,679
Speaker 1: to we need to unstrapped in there. All right. Well,

454
00:24:31,720 --> 00:24:33,720
Speaker 1: on that note, then we're gonna go ahead and sign

455
00:24:33,800 --> 00:24:35,800
Speaker 1: out here. You can find us in all the normal

456
00:24:35,880 --> 00:24:37,960
Speaker 1: places if you want to reach out to us and

457
00:24:38,040 --> 00:24:40,320
Speaker 1: tell us about your experiences as a lefty in a

458
00:24:40,480 --> 00:24:43,440
Speaker 1: right handed world, or your experience of variety living with

459
00:24:43,520 --> 00:24:46,399
Speaker 1: a lefty all of its fair game, or let us

460
00:24:46,440 --> 00:24:47,840
