People. I hate 19 00:01:11,080 --> 00:01:12,920 Speaker 1: that you miss out on that kind of stuff, But 20 00:01:13,000 --> 00:01:15,520 Speaker 1: you know what, that's a that's for us. We we 21 00:01:15,560 --> 00:01:19,200 Speaker 1: deserve a little something. Yeah, And that's called pre show 22 00:01:19,440 --> 00:01:24,400 Speaker 1: fun fun hammering out the details, hammer and other details. 23 00:01:24,680 --> 00:01:28,880 Speaker 1: I thoroughly enjoyed researching this one. Oh really, it burned 24 00:01:28,880 --> 00:01:30,440 Speaker 1: my brain a little bit. It burned my brain a 25 00:01:30,480 --> 00:01:33,640 Speaker 1: little bit too. But um, I just I didn't know 26 00:01:33,680 --> 00:01:37,800 Speaker 1: anything about handedness and uh no not really don't use 27 00:01:37,840 --> 00:01:40,360 Speaker 1: your hands much. Well, I mean as far as uh 28 00:01:40,480 --> 00:01:43,000 Speaker 1: why you are left or right handed or ambidextrous. It 29 00:01:43,080 --> 00:01:46,200 Speaker 1: was all kind of new information for me. I feel 30 00:01:46,200 --> 00:01:48,840 Speaker 1: like I had read that IO nine article, which we 31 00:01:48,840 --> 00:01:50,760 Speaker 1: should give a huge shout out, because I was in 32 00:01:50,800 --> 00:01:55,000 Speaker 1: forming partially the basis of this um episode. Yeah, why 33 00:01:55,040 --> 00:01:57,280 Speaker 1: are so few people left handed? From IO nine and 34 00:01:57,320 --> 00:02:01,120 Speaker 1: they sourced a lot of great stuff and Discover magazine 35 00:02:01,200 --> 00:02:05,200 Speaker 1: and their articles so and science and science. So it's legit. 36 00:02:05,360 --> 00:02:11,400 Speaker 1: It is legit, uh possibly even to legit to quit yeah, yeah, 37 00:02:11,520 --> 00:02:13,720 Speaker 1: which I could not do with my left hand. I 38 00:02:13,720 --> 00:02:16,760 Speaker 1: guess I can't. I just did it. You just did 39 00:02:16,840 --> 00:02:21,160 Speaker 1: to your sign sign signing to me. Yeah, I'm equally 40 00:02:21,200 --> 00:02:25,000 Speaker 1: bad at at doing too legit to quit finger motions 41 00:02:25,040 --> 00:02:27,440 Speaker 1: with either hand. I'm right handed, by the way, what 42 00:02:27,480 --> 00:02:30,760 Speaker 1: about you, I'm right handed, but that is weird since 43 00:02:30,760 --> 00:02:32,520 Speaker 1: you have your MC hammer pants on. I thought you 44 00:02:32,520 --> 00:02:35,000 Speaker 1: would be good at that. That's all. Just it's not 45 00:02:35,040 --> 00:02:37,240 Speaker 1: hard to put on pants. It's hard to do too 46 00:02:37,360 --> 00:02:40,720 Speaker 1: legit to quit finger motions. Yeah, I'm right handed. Um 47 00:02:40,760 --> 00:02:42,519 Speaker 1: to well, I was about to say to a fault, 48 00:02:42,560 --> 00:02:45,960 Speaker 1: but heavily heavily right handed, because after reading this, I 49 00:02:45,960 --> 00:02:48,559 Speaker 1: do believe that there is a bit of a spectrum. 50 00:02:48,600 --> 00:02:52,880 Speaker 1: I think, um, oh, yeah, yeah, I think. I think 51 00:02:52,919 --> 00:02:55,880 Speaker 1: some people are way dominant with their one hand, and 52 00:02:55,919 --> 00:02:58,200 Speaker 1: some people skew more towards you. I can do some 53 00:02:58,240 --> 00:03:01,399 Speaker 1: things with this hand. Uh, and some people are ambidexterous, 54 00:03:01,440 --> 00:03:04,600 Speaker 1: which we'll talk about very few though fewer than you think. Yeah, 55 00:03:04,720 --> 00:03:08,040 Speaker 1: but um, I am heavily heavily right handed. I cannot 56 00:03:08,120 --> 00:03:14,519 Speaker 1: do many uh what's the word I'm looking for, um, 57 00:03:14,560 --> 00:03:17,919 Speaker 1: trying to find my not like my fine motor skill tasks. 58 00:03:18,480 --> 00:03:20,760 Speaker 1: I cannot do very well with my left hand. I 59 00:03:20,800 --> 00:03:23,520 Speaker 1: can just like club things and smack things and knock 60 00:03:23,560 --> 00:03:26,920 Speaker 1: stuff over and knock stuff over like Frankenstein clearing at 61 00:03:27,000 --> 00:03:29,880 Speaker 1: table pretty much. What about you? And can you do 62 00:03:29,919 --> 00:03:32,240 Speaker 1: anything with your left hand? I used to think I was, 63 00:03:33,160 --> 00:03:36,040 Speaker 1: you know, pretty much just strictly right handed, but then 64 00:03:36,080 --> 00:03:39,440 Speaker 1: I I especially researching this. I paid attention, and I'm like, no, 65 00:03:40,000 --> 00:03:42,160 Speaker 1: I used my my left hand a little more than 66 00:03:42,200 --> 00:03:44,760 Speaker 1: I thought. I'm definitely not ambidextrous, and if there is 67 00:03:44,800 --> 00:03:47,000 Speaker 1: such a thing as a dominant hand, it's clearly my right. 68 00:03:47,320 --> 00:03:50,120 Speaker 1: But this this article points out, or actually it was 69 00:03:50,160 --> 00:03:55,400 Speaker 1: a science Um article that said, there's there's this idea 70 00:03:55,480 --> 00:03:58,760 Speaker 1: that there isn't a dominant hand that you have uses 71 00:03:58,840 --> 00:04:01,120 Speaker 1: for both hands in one kind of specializes in one 72 00:04:01,160 --> 00:04:04,160 Speaker 1: thing and one specializes in another. And the the example 73 00:04:04,200 --> 00:04:07,600 Speaker 1: they used to illustrate that was um cutting like meat 74 00:04:07,640 --> 00:04:09,680 Speaker 1: with a fork and knife. Yeah. I was gonna ask 75 00:04:09,680 --> 00:04:12,440 Speaker 1: you about that, you know, like I was thinking about it. 76 00:04:12,440 --> 00:04:13,720 Speaker 1: I was like, oh, yeah, I guess I do use 77 00:04:13,760 --> 00:04:16,440 Speaker 1: the knife pretty well with my left hand. I thought, crazy, No, 78 00:04:16,920 --> 00:04:19,720 Speaker 1: my fork is in my left hand. My knife is 79 00:04:19,760 --> 00:04:22,520 Speaker 1: in my right hand too, and then I switched the 80 00:04:22,520 --> 00:04:24,520 Speaker 1: fork over to my right hand. That's what I did too. 81 00:04:24,560 --> 00:04:26,880 Speaker 1: I was gonna ask you that. So I'm definitely right handed, 82 00:04:26,920 --> 00:04:29,080 Speaker 1: but you know, my left hand does a great job 83 00:04:29,279 --> 00:04:32,280 Speaker 1: holding the steak in place with my fork while I 84 00:04:32,320 --> 00:04:34,440 Speaker 1: cut it with the knife. Yeah, well, I come to 85 00:04:34,440 --> 00:04:37,280 Speaker 1: think of it, though, I play guitar in drums, So 86 00:04:37,400 --> 00:04:40,560 Speaker 1: I mean I have some left hand skill, I guess, um. 87 00:04:40,600 --> 00:04:43,200 Speaker 1: And I know if you break your dominant hand, you're 88 00:04:43,200 --> 00:04:47,040 Speaker 1: gonna learn pretty quickly how to adapt, So it's possible 89 00:04:47,080 --> 00:04:50,840 Speaker 1: to learn, uh force do. Yes, it's all very interesting 90 00:04:50,839 --> 00:04:52,599 Speaker 1: to me. It is, and we should say if you 91 00:04:52,720 --> 00:04:56,359 Speaker 1: happen happen just randomly to be listening to this episode 92 00:04:56,440 --> 00:05:02,640 Speaker 1: on August Happy National Left Handed Day, Yeah, I looked 93 00:05:02,640 --> 00:05:03,800 Speaker 1: out when I looked that up, I was like, I 94 00:05:03,880 --> 00:05:05,960 Speaker 1: wouldn't it be one of those another stuff you should 95 00:05:05,960 --> 00:05:09,640 Speaker 1: know coincidence if this was happened to be released that No, 96 00:05:09,800 --> 00:05:13,480 Speaker 1: not even close. Yeah. Um. And it's good that left 97 00:05:13,520 --> 00:05:15,680 Speaker 1: handed people have their own day because they've been fairly 98 00:05:15,720 --> 00:05:21,960 Speaker 1: maligned throughout the millennia. Yeah, let's talk about that. Actually, okay, Um, 99 00:05:22,000 --> 00:05:25,160 Speaker 1: throughout history. In fact, even if you look at the 100 00:05:25,160 --> 00:05:30,400 Speaker 1: words throughout history, there is a you know, uh the 101 00:05:30,480 --> 00:05:33,800 Speaker 1: poopoo left handers basically, Yeah, Like the word l y 102 00:05:34,040 --> 00:05:38,640 Speaker 1: f T left yeah, from Anglo Saxon means weak and 103 00:05:39,000 --> 00:05:41,200 Speaker 1: that's where the word left comes from. Yeah, And the 104 00:05:41,240 --> 00:05:44,279 Speaker 1: word sinister from Latin is the word for left. Yeah. 105 00:05:44,279 --> 00:05:46,880 Speaker 1: Anybody who saw that episode of the Simpsons where Ned 106 00:05:46,880 --> 00:05:50,480 Speaker 1: Flanders opens the left Toorium knows that because he says, 107 00:05:50,839 --> 00:05:54,680 Speaker 1: I have a a sinister reason to invite you all here, 108 00:05:54,839 --> 00:05:57,839 Speaker 1: sinister meaning left handed man. And that was when he 109 00:05:57,839 --> 00:06:00,520 Speaker 1: announced the Leftorium. That show was so smart, you know, 110 00:06:00,760 --> 00:06:03,359 Speaker 1: very smart. So many of those jokes like just flew 111 00:06:03,360 --> 00:06:06,560 Speaker 1: over my head back in the day. Well they're coming 112 00:06:06,600 --> 00:06:10,599 Speaker 1: back to roost. Uh. There's a long list of um. 113 00:06:10,839 --> 00:06:15,960 Speaker 1: Countries who have languages that link the word right with 114 00:06:16,040 --> 00:06:20,960 Speaker 1: being good, uh, in the left with being bad or wrong. Uh. 115 00:06:21,040 --> 00:06:24,320 Speaker 1: And in some countries even making hand gestures with your 116 00:06:24,400 --> 00:06:27,240 Speaker 1: left hand is a no no well and a lot 117 00:06:27,279 --> 00:06:30,080 Speaker 1: of countries are a lot of cultures that eat food 118 00:06:30,120 --> 00:06:33,800 Speaker 1: with their hands rather than utensils. Um. Using the left 119 00:06:33,800 --> 00:06:36,039 Speaker 1: hand to eat or do a lot of things with 120 00:06:36,200 --> 00:06:39,720 Speaker 1: is considered taboo because it's exactly right. You use the 121 00:06:39,800 --> 00:06:41,839 Speaker 1: right hand to eat with, use your left hand to 122 00:06:41,839 --> 00:06:45,200 Speaker 1: wipe with right and um, I think if you pay 123 00:06:45,240 --> 00:06:48,680 Speaker 1: attention and notice, I'll bet you have a hand that's 124 00:06:48,760 --> 00:06:52,840 Speaker 1: dominant and that that um activity wipe in your butt. 125 00:06:53,000 --> 00:06:56,680 Speaker 1: Yeah yeah, I'm already are you Oh yeah, okay, But 126 00:06:56,920 --> 00:07:00,200 Speaker 1: if you if you try the other hand, I'll feel 127 00:07:00,279 --> 00:07:03,600 Speaker 1: very weird. Whatever whatever hand you use normally, it's gonna 128 00:07:03,600 --> 00:07:05,479 Speaker 1: feel weird if you use the opia, and you'll just 129 00:07:05,520 --> 00:07:09,000 Speaker 1: end up very messy. Sure, I wonder if you had 130 00:07:09,000 --> 00:07:11,239 Speaker 1: a subconscious thing like you know, I was just eating 131 00:07:11,240 --> 00:07:13,520 Speaker 1: these candy pecons with my right hand, and I know 132 00:07:13,560 --> 00:07:15,160 Speaker 1: I'm going to go back and eat them with my 133 00:07:15,280 --> 00:07:17,600 Speaker 1: right hand. Oh, I don't even use my hands to eat. 134 00:07:17,640 --> 00:07:20,840 Speaker 1: I'm I'm a little too germ conscious. I scoop food 135 00:07:20,880 --> 00:07:23,280 Speaker 1: up in the croak of my elbow, which is very 136 00:07:23,280 --> 00:07:25,800 Speaker 1: clean because it doesn't come in contact of other stuff, 137 00:07:25,840 --> 00:07:27,800 Speaker 1: and then I eat out of the croak of my elbow. 138 00:07:27,880 --> 00:07:33,440 Speaker 1: That's pretty funny. Um. So why have people been I mean, 139 00:07:33,480 --> 00:07:36,360 Speaker 1: why have they picked on left handed people? There are 140 00:07:36,400 --> 00:07:39,640 Speaker 1: some theories that it's just a minority. You know, ten 141 00:07:40,520 --> 00:07:43,280 Speaker 1: of people are left handed, and throughout history minorities have 142 00:07:43,320 --> 00:07:46,080 Speaker 1: been picked on. That's right, this one thing. Um, there's 143 00:07:46,160 --> 00:07:49,560 Speaker 1: there's at least a couple of cultures that equate left 144 00:07:49,600 --> 00:07:52,960 Speaker 1: handedness with clumsiness. Yeah, that makes sense to me. Some 145 00:07:53,120 --> 00:07:59,560 Speaker 1: hypotheses theorized that UM tools tool making. For a very 146 00:07:59,600 --> 00:08:03,280 Speaker 1: long time time, UM has been done following right handed techniques. 147 00:08:03,600 --> 00:08:07,320 Speaker 1: Still is in many cases. Um, and so when a 148 00:08:07,440 --> 00:08:10,440 Speaker 1: lefty was trying to make tools or do whatever using 149 00:08:10,600 --> 00:08:13,840 Speaker 1: right handed tools, they would have been clumsy with them. 150 00:08:13,920 --> 00:08:17,640 Speaker 1: And therefore the idea that left handed people were clumsy 151 00:08:17,800 --> 00:08:22,080 Speaker 1: or weak or whatever could have developed and carried on. Yeah, like, uh, 152 00:08:23,000 --> 00:08:26,600 Speaker 1: colonial day, dad is teaching his two sons. Let's go 153 00:08:26,640 --> 00:08:28,760 Speaker 1: with the son and a daughter even, let's mix it up, 154 00:08:29,080 --> 00:08:31,480 Speaker 1: how to use a saw. And you know, the son's 155 00:08:31,560 --> 00:08:34,480 Speaker 1: left handed and he keeps he can't saw. Well, so 156 00:08:34,559 --> 00:08:37,359 Speaker 1: the dad's just like he favors the daughter because she's 157 00:08:37,400 --> 00:08:39,760 Speaker 1: you know, she's better with the saw. It's just it's 158 00:08:39,800 --> 00:08:41,760 Speaker 1: easy to see how that could happen. Like he's mad 159 00:08:41,800 --> 00:08:45,880 Speaker 1: at Roger but pleased with Prudence because Prudence she's always 160 00:08:46,040 --> 00:08:49,680 Speaker 1: sawing things. Well that's a colonial name. Yeah, sure, well 161 00:08:49,720 --> 00:08:54,080 Speaker 1: I feel like it is. Okay, Well what else is there? Who? Goody? 162 00:08:54,160 --> 00:09:01,280 Speaker 1: Uh goody Alice. Okay, it's timeless, um, but there's still that. 163 00:09:01,840 --> 00:09:04,000 Speaker 1: If you're lefty today, you might be frustrated with things 164 00:09:04,040 --> 00:09:07,439 Speaker 1: like scissors and can openers and spiral notebooks and things 165 00:09:07,440 --> 00:09:11,160 Speaker 1: that sort of favor the right handed. Yeah, you're sitting 166 00:09:11,240 --> 00:09:15,120 Speaker 1: next to a right handed person at dinner. The elbow thing. 167 00:09:15,160 --> 00:09:18,839 Speaker 1: It's the worst. It's because there's so few left handed people. 168 00:09:18,840 --> 00:09:21,439 Speaker 1: If you're planning a dinner party, first of all, it's 169 00:09:21,480 --> 00:09:24,000 Speaker 1: just common courtesy to know the handedness of all of 170 00:09:24,040 --> 00:09:27,520 Speaker 1: your guests and then to put them appropriately right. To 171 00:09:27,640 --> 00:09:29,520 Speaker 1: put the left handed person at the end of the 172 00:09:29,559 --> 00:09:32,440 Speaker 1: table so that their left hand is their left elbow 173 00:09:32,559 --> 00:09:34,400 Speaker 1: is off the table, and they don't have to worry 174 00:09:34,400 --> 00:09:37,400 Speaker 1: about bumping into other people. Yeah, my mom is left handed, 175 00:09:37,440 --> 00:09:41,080 Speaker 1: my father is right handed, and you came out right 176 00:09:41,120 --> 00:09:48,680 Speaker 1: handed crazy, I sure did so. Um, despite everybody knowing 177 00:09:48,720 --> 00:09:51,560 Speaker 1: that there's a right handedness and a left handedness, it 178 00:09:51,640 --> 00:09:56,400 Speaker 1: turns out, after investigating this kind of thing, science is 179 00:09:56,640 --> 00:09:59,480 Speaker 1: really baffled as to what exactly is going on. Why 180 00:09:59,559 --> 00:10:02,960 Speaker 1: we would have handedness, yeah at all, where it comes from. 181 00:10:03,440 --> 00:10:07,680 Speaker 1: Why the proportions seem to be steady. There's a lot 182 00:10:07,720 --> 00:10:11,600 Speaker 1: of questions that you know, come up when you look 183 00:10:11,640 --> 00:10:14,240 Speaker 1: into handedness. Whereas you know the average person who just 184 00:10:14,320 --> 00:10:18,679 Speaker 1: kind of taken for granted, but no, not the average scientists. No, No. 185 00:10:19,000 --> 00:10:22,600 Speaker 1: There are a lot of interesting theories though. Um. One 186 00:10:22,720 --> 00:10:25,960 Speaker 1: is is that, uh, as we all know, we have 187 00:10:25,960 --> 00:10:28,240 Speaker 1: a left hemisphere in the right hemisphere of our brain, 188 00:10:28,920 --> 00:10:31,520 Speaker 1: and we are one of the only mammals that are 189 00:10:31,640 --> 00:10:35,280 Speaker 1: very much um, have a it's called brain lateralization when 190 00:10:36,000 --> 00:10:38,559 Speaker 1: primarily and this isn't across the board, but primarily one 191 00:10:38,600 --> 00:10:41,280 Speaker 1: hemisphere controls certain things and the other controls other things. 192 00:10:41,840 --> 00:10:44,400 Speaker 1: And that is primarily controlling the opposite side of the 193 00:10:44,440 --> 00:10:51,760 Speaker 1: body as the hemisphere. UM. But language and um controlling 194 00:10:51,800 --> 00:10:54,080 Speaker 1: your you know, fine motor skills like things you do 195 00:10:54,080 --> 00:10:57,840 Speaker 1: with your hands and your fingers have often been linked 196 00:10:58,000 --> 00:11:02,720 Speaker 1: because uh, they are generally on link together and on 197 00:11:02,720 --> 00:11:06,000 Speaker 1: one hemisphere of the brain right for for the most part, 198 00:11:06,040 --> 00:11:07,599 Speaker 1: people who are right hand and they make up the 199 00:11:07,679 --> 00:11:11,400 Speaker 1: vast majority of human beings. By the way, Yeah, I 200 00:11:11,400 --> 00:11:13,679 Speaker 1: saw as low as seventy, but nothing lower than that, 201 00:11:13,880 --> 00:11:19,040 Speaker 1: you know, eighty didn't Yeah, you're right, sorry, exactly, UM. 202 00:11:20,240 --> 00:11:23,839 Speaker 1: Those people have their language center in the left hemisphere, 203 00:11:23,960 --> 00:11:27,360 Speaker 1: and I guess also their motor cortex in the left hemisphere, 204 00:11:28,040 --> 00:11:33,400 Speaker 1: and the know, the left and the Uh. There's a 205 00:11:33,440 --> 00:11:35,360 Speaker 1: lot of questions about why this would be when the 206 00:11:35,400 --> 00:11:39,120 Speaker 1: brain supposedly is a is always looking for efficiencies as 207 00:11:39,160 --> 00:11:42,319 Speaker 1: much as possible. So they're saying, okay, well, these are 208 00:11:42,400 --> 00:11:48,480 Speaker 1: two very human activities speech, language, and using your fingers 209 00:11:48,480 --> 00:11:52,240 Speaker 1: to do stuff right right, So, um, they're also some 210 00:11:52,320 --> 00:11:55,560 Speaker 1: of the more complex activities that humans engage in. So 211 00:11:55,600 --> 00:11:57,280 Speaker 1: it makes sense that you just leave it up to 212 00:11:57,360 --> 00:11:59,720 Speaker 1: one side of the brain so that these things can 213 00:12:00,280 --> 00:12:04,280 Speaker 1: um not have to cross over the corpus colossum. Yeah, 214 00:12:04,320 --> 00:12:06,640 Speaker 1: it's it's just like cluster together. It makes sense. It 215 00:12:06,720 --> 00:12:10,000 Speaker 1: does make sense, but it's also a pretty thin explanation. 216 00:12:10,120 --> 00:12:13,199 Speaker 1: If you you could also say the other the exact opposite, 217 00:12:13,200 --> 00:12:16,000 Speaker 1: that it would make more sense that our motor skills 218 00:12:16,080 --> 00:12:18,160 Speaker 1: and our language skills would be in opposite sides of 219 00:12:18,200 --> 00:12:20,959 Speaker 1: the brain to give each other a break, rather than 220 00:12:21,000 --> 00:12:24,280 Speaker 1: just weighting it down on the same side. The point is, though, 221 00:12:24,360 --> 00:12:27,600 Speaker 1: is if you crack open a human brain and you 222 00:12:27,760 --> 00:12:31,400 Speaker 1: look for the motor cortex and the language region, the 223 00:12:31,480 --> 00:12:35,640 Speaker 1: language center, you're going to find them most likely, statistically speaking, 224 00:12:35,920 --> 00:12:40,400 Speaker 1: on the left hemisphere. Hence more right handedness right because 225 00:12:40,440 --> 00:12:43,680 Speaker 1: of what you said that, um, that brain lateralization where 226 00:12:43,840 --> 00:12:46,880 Speaker 1: stuff that's carried out in the left hemisphere is going 227 00:12:46,960 --> 00:12:50,520 Speaker 1: to manifest itself in the right. So if you're shaking 228 00:12:50,520 --> 00:12:53,559 Speaker 1: somebody's hand using your right hand, the left hemisphere is 229 00:12:53,960 --> 00:12:57,920 Speaker 1: blowing up. That's right. If you're taking in um visual 230 00:12:57,960 --> 00:13:00,280 Speaker 1: information with just your left eye because you got right 231 00:13:00,320 --> 00:13:02,400 Speaker 1: eye closed or it was poked out by a seagull 232 00:13:02,520 --> 00:13:05,360 Speaker 1: or whatever, then your right hemisphere is going to be 233 00:13:05,440 --> 00:13:10,640 Speaker 1: active rights right. Interestingly, though, if the opposite isn't true, 234 00:13:10,679 --> 00:13:15,520 Speaker 1: If you have your language center in your right hemisphere, 235 00:13:16,200 --> 00:13:19,160 Speaker 1: it doesn't always mean that you're going to be left handed. 236 00:13:19,640 --> 00:13:22,200 Speaker 1: It means you're more likely to. But um, I like 237 00:13:22,280 --> 00:13:24,000 Speaker 1: the way this article looked at it. It's it's an 238 00:13:24,040 --> 00:13:26,720 Speaker 1: evolutionary rule of thumb. It's not. I think they said 239 00:13:26,720 --> 00:13:31,000 Speaker 1: between sixty one and seventy of lefties have the language 240 00:13:31,000 --> 00:13:37,160 Speaker 1: centers on the left um over of right handed people right, 241 00:13:37,160 --> 00:13:41,040 Speaker 1: which raises a really great question. Are is there such 242 00:13:41,040 --> 00:13:44,800 Speaker 1: a thing as right eas and lefties or is there 243 00:13:44,800 --> 00:13:47,160 Speaker 1: such a thing as right ees and non right ees? 244 00:13:47,960 --> 00:13:50,760 Speaker 1: Because if there, if if a righty and a lefty 245 00:13:50,800 --> 00:13:54,000 Speaker 1: are equally exactly the same thing, if handedness is completely 246 00:13:54,440 --> 00:13:58,000 Speaker 1: u binary like that, Yeah, then if you're a lefty, 247 00:13:58,160 --> 00:14:00,800 Speaker 1: your language center should be on the right hand side, 248 00:14:00,840 --> 00:14:02,760 Speaker 1: and that, like you said, that's just not the case 249 00:14:02,800 --> 00:14:07,280 Speaker 1: in most lefties even Yeah, that's true, And the I 250 00:14:07,480 --> 00:14:11,760 Speaker 1: nine article also points out that it's they don't know 251 00:14:11,800 --> 00:14:14,480 Speaker 1: why necessarily, but this is just how we evolved. It 252 00:14:14,520 --> 00:14:17,000 Speaker 1: could have just been the opposite and then we'd have 253 00:14:17,040 --> 00:14:21,680 Speaker 1: more lefties. Right, Yeah, well that's the idea. But I think, um, 254 00:14:21,720 --> 00:14:25,480 Speaker 1: there are a couple of the explanations, possibly of genetic 255 00:14:25,520 --> 00:14:29,480 Speaker 1: mutations along the way too, In particular, uh one about 256 00:14:29,480 --> 00:14:34,240 Speaker 1: two hundred thousand years ago that basically mutated us to 257 00:14:34,600 --> 00:14:37,320 Speaker 1: the fact that we are going to be more right 258 00:14:37,360 --> 00:14:39,000 Speaker 1: handed in the in the language center is going to 259 00:14:39,040 --> 00:14:43,040 Speaker 1: be on the left hand side. Uh. And then more recently, um, 260 00:14:43,080 --> 00:14:46,280 Speaker 1: there's a theory that there was a second mutation uh 261 00:14:46,480 --> 00:14:49,280 Speaker 1: two between twenty thousand and a hundred thousand years ago 262 00:14:49,960 --> 00:14:53,560 Speaker 1: where that basically balanced things out or it canceled that out, 263 00:14:53,920 --> 00:14:57,520 Speaker 1: which means the possibility of left handedness became a thing, 264 00:14:57,600 --> 00:14:59,760 Speaker 1: or else we would have all been right handed. Right. 265 00:15:00,720 --> 00:15:02,680 Speaker 1: That makes sense too. It does make sense and that 266 00:15:03,680 --> 00:15:08,240 Speaker 1: the humans possibly evolved to use their hands more, and 267 00:15:08,280 --> 00:15:11,000 Speaker 1: by using their hands more, our brains were forced to 268 00:15:11,080 --> 00:15:14,880 Speaker 1: become specialized and basically forced to choose. So then some 269 00:15:14,920 --> 00:15:18,920 Speaker 1: sort of gene was set up that made the developing 270 00:15:19,000 --> 00:15:22,240 Speaker 1: human brain most likely to be a right handed person, right, 271 00:15:23,280 --> 00:15:26,400 Speaker 1: and then that second gene came along and canceled that 272 00:15:26,440 --> 00:15:29,440 Speaker 1: out in some parts of the population. Yeah. I think 273 00:15:29,480 --> 00:15:33,080 Speaker 1: it's the D gene and the C gene. Um. There 274 00:15:33,080 --> 00:15:36,960 Speaker 1: are two alleles, which is the manifestations of a gene 275 00:15:36,960 --> 00:15:42,000 Speaker 1: at the same location. And the D gene is more 276 00:15:42,040 --> 00:15:45,320 Speaker 1: frequent in the population, so it's more uh, promotes the 277 00:15:45,400 --> 00:15:48,040 Speaker 1: right handed preference. The C gene is less likely within 278 00:15:48,080 --> 00:15:50,800 Speaker 1: the gene pool. Uh. And so there you have like 279 00:15:50,840 --> 00:15:55,080 Speaker 1: a fifty fifty chance of being left handed if you 280 00:15:55,120 --> 00:15:58,920 Speaker 1: have that C gene. Okay, I got you. Yeah, But 281 00:15:59,000 --> 00:16:02,080 Speaker 1: you don't have a fifty chance of being a left 282 00:16:02,200 --> 00:16:04,840 Speaker 1: handed person in general. You have about it only if 283 00:16:04,840 --> 00:16:07,920 Speaker 1: you had chance. Yeah, because the D gene is more prominent, 284 00:16:08,240 --> 00:16:11,160 Speaker 1: and that means almost certainly you're going to be right handed. Okay. 285 00:16:11,160 --> 00:16:13,280 Speaker 1: So the caveat we should add to all of this 286 00:16:13,400 --> 00:16:17,480 Speaker 1: is that, um, this is all just strictly conjecture. Um. 287 00:16:17,600 --> 00:16:19,440 Speaker 1: And we'll get to a little more of this conjecture 288 00:16:19,640 --> 00:16:38,920 Speaker 1: right after this. So, Chuck, we were saying that it's 289 00:16:38,960 --> 00:16:43,440 Speaker 1: possible that genetic mutations far back in human history account 290 00:16:43,480 --> 00:16:46,280 Speaker 1: for this, and um, there is a lot of evidence 291 00:16:46,360 --> 00:16:50,280 Speaker 1: that there have humans have been mostly right handed for 292 00:16:50,320 --> 00:16:53,880 Speaker 1: about the last two d thousand years. Fossil evidence suggests this. 293 00:16:54,000 --> 00:16:59,720 Speaker 1: Looking at um neanderthal skeletons early human skeletons, UM, you 294 00:16:59,760 --> 00:17:03,000 Speaker 1: can see evidence on the skeletons of right handedness, and 295 00:17:03,040 --> 00:17:07,600 Speaker 1: they think that it's so obvious and obviously prominent because 296 00:17:07,600 --> 00:17:11,280 Speaker 1: these people were using things like spears, So if they 297 00:17:11,400 --> 00:17:15,600 Speaker 1: did have a hand preference, then a spear would definitely 298 00:17:15,640 --> 00:17:19,480 Speaker 1: develop that arm connected to that hand, and it would 299 00:17:19,480 --> 00:17:23,440 Speaker 1: stay in the fossil record through the skeletons right They 300 00:17:23,480 --> 00:17:26,840 Speaker 1: also have looked at other fossils as far back as 301 00:17:26,920 --> 00:17:30,479 Speaker 1: one point six million years. There's a skeleton called I 302 00:17:30,520 --> 00:17:33,360 Speaker 1: want to say the Kokomo Boy even though it's not, 303 00:17:33,480 --> 00:17:39,159 Speaker 1: but I love that song. It's the Nariokotome Boy. Sure 304 00:17:40,560 --> 00:17:43,080 Speaker 1: uh and he is a one point six million year 305 00:17:43,119 --> 00:17:47,600 Speaker 1: old Homo air gaster and um they he he was 306 00:17:47,680 --> 00:17:50,719 Speaker 1: clearly right handed as well. Other fossils have turned up 307 00:17:51,000 --> 00:17:54,639 Speaker 1: evidence of right handedness the the teeth. Striations on the 308 00:17:54,640 --> 00:17:58,439 Speaker 1: teeth suggest eating with their right hand. So what we 309 00:17:58,520 --> 00:18:01,200 Speaker 1: what we can say with a pretty decent amount of confidences, 310 00:18:01,240 --> 00:18:04,520 Speaker 1: at least for the last two hundred thousand years, humanity 311 00:18:04,600 --> 00:18:08,679 Speaker 1: has been a majority right handers, and there's been maybe 312 00:18:08,720 --> 00:18:14,560 Speaker 1: about this constant ten proportion of left handed people, which 313 00:18:14,680 --> 00:18:17,520 Speaker 1: makes the mystery even more crazy to me. Yeah, but 314 00:18:17,600 --> 00:18:22,080 Speaker 1: it also makes sense that um an early tool building 315 00:18:22,160 --> 00:18:25,480 Speaker 1: and teaching how to use tools. UM, I mean it 316 00:18:25,520 --> 00:18:28,040 Speaker 1: holds true today. They've done studies that you know, you 317 00:18:28,119 --> 00:18:30,680 Speaker 1: teach your son or daughter to tie a tie, and 318 00:18:31,040 --> 00:18:33,200 Speaker 1: it's it's going to be more difficult if they're left 319 00:18:33,200 --> 00:18:34,960 Speaker 1: handed and you're right handed for them to try and 320 00:18:35,680 --> 00:18:37,760 Speaker 1: do it with their left hand. So there they'll pick 321 00:18:37,800 --> 00:18:41,080 Speaker 1: it up easier if they go against their instinct and 322 00:18:41,160 --> 00:18:44,880 Speaker 1: learn it how you've talked with. The studies have shown that, Yeah, 323 00:18:44,880 --> 00:18:47,480 Speaker 1: so you learned faster from watching somebody and then using 324 00:18:47,520 --> 00:18:51,080 Speaker 1: the same hand. The Yeah, and that makes sense. Back 325 00:18:51,119 --> 00:18:53,720 Speaker 1: in the you know, with Took took In showing his 326 00:18:53,880 --> 00:18:58,840 Speaker 1: pal how to use the bone to smash skull. You know, 327 00:18:59,200 --> 00:19:01,480 Speaker 1: it's if he picks of his buddy picks up with 328 00:19:01,560 --> 00:19:05,800 Speaker 1: this left hand, Took Took's gonna shake his head, no, no, yeah, 329 00:19:05,960 --> 00:19:08,119 Speaker 1: use right hand or they're just gonna you know, they 330 00:19:08,119 --> 00:19:10,199 Speaker 1: want everyone wants to fit in, even back at in 331 00:19:10,240 --> 00:19:14,080 Speaker 1: the old days. Well that's actually a suggestion of why 332 00:19:14,480 --> 00:19:18,359 Speaker 1: left handedness is possibly not a little more prevalent among 333 00:19:18,560 --> 00:19:22,360 Speaker 1: a certain age group today because it was equated with 334 00:19:22,480 --> 00:19:27,160 Speaker 1: being weird or off or crazy or whatever. Um, and 335 00:19:27,600 --> 00:19:32,320 Speaker 1: parents and teachers would force children to learn how to 336 00:19:32,400 --> 00:19:36,320 Speaker 1: write with their right hand, effectively wiping out a lot 337 00:19:36,400 --> 00:19:41,240 Speaker 1: of the left handed population. Yeah, and um, just jumping 338 00:19:41,240 --> 00:19:44,160 Speaker 1: back a minute, I wanted to mention something important that 339 00:19:44,560 --> 00:19:48,680 Speaker 1: the whole correlation versus causation thing um with the whole 340 00:19:48,760 --> 00:19:52,960 Speaker 1: language center link. Uh, it's not necessarily that that's a correlation. 341 00:19:53,280 --> 00:19:56,560 Speaker 1: They appear to be strongly linked, but no one is 342 00:19:56,600 --> 00:20:00,000 Speaker 1: saying that because the language hemisphere is on the left 343 00:20:00,000 --> 00:20:02,479 Speaker 1: side of your brain, that's causing you to be right handed. Right. 344 00:20:02,520 --> 00:20:05,399 Speaker 1: They there, And again, the reason that they are linked 345 00:20:05,840 --> 00:20:09,840 Speaker 1: in a lot of scientists minds is that speech and 346 00:20:10,480 --> 00:20:15,359 Speaker 1: fine motor skills are basically uniquely human, almost uniquely human. 347 00:20:15,920 --> 00:20:18,959 Speaker 1: And it's just a little it's kind of like a 348 00:20:19,040 --> 00:20:22,679 Speaker 1: red flag or a signal that they're both usually in 349 00:20:22,720 --> 00:20:25,520 Speaker 1: the same hemisphere, and they do seem to be connected. 350 00:20:25,960 --> 00:20:28,639 Speaker 1: And one hypothesis for why they're connected, I thought was 351 00:20:28,720 --> 00:20:34,520 Speaker 1: pretty smart. Um. The idea that language spoken language emerged 352 00:20:34,560 --> 00:20:38,880 Speaker 1: out of gestures hand movements, which would require fine motor skills, 353 00:20:39,320 --> 00:20:41,560 Speaker 1: right that I don't have trying to do the two 354 00:20:41,640 --> 00:20:45,240 Speaker 1: legit to quit things. But the idea that language emerged 355 00:20:45,280 --> 00:20:48,520 Speaker 1: out of that would suggest some sort of connection between 356 00:20:48,520 --> 00:20:51,480 Speaker 1: the two, Like maybe the fine motor skill section is 357 00:20:51,520 --> 00:20:54,320 Speaker 1: the more ancient of the two, and then language evolved 358 00:20:54,359 --> 00:20:57,280 Speaker 1: out of that. But we also still need our fine 359 00:20:57,320 --> 00:20:59,600 Speaker 1: motor skills to like eat with a fork and knife. 360 00:20:59,640 --> 00:21:02,040 Speaker 1: And I mean, so it stuck around. It didn't become 361 00:21:02,040 --> 00:21:06,320 Speaker 1: obsolete just because we started speaking. Yeah, I like that theory. Um. 362 00:21:06,480 --> 00:21:10,000 Speaker 1: We we did mention that this is a largely uniquely 363 00:21:10,080 --> 00:21:14,520 Speaker 1: human trait um, But they have followed. Uh, they've basically 364 00:21:14,600 --> 00:21:17,640 Speaker 1: been looking at our closest ancestors to try and figure 365 00:21:17,680 --> 00:21:19,200 Speaker 1: a lot of this stuff out. Although it did see 366 00:21:19,240 --> 00:21:22,960 Speaker 1: some studies that said that, like cats are left handed 367 00:21:22,960 --> 00:21:24,920 Speaker 1: because they'll go to swat things with their left hand, 368 00:21:25,560 --> 00:21:28,719 Speaker 1: but um, I'm not so sure about that. Yeah, there's 369 00:21:28,840 --> 00:21:33,520 Speaker 1: not only is it difficult apparently to um test or 370 00:21:33,560 --> 00:21:37,160 Speaker 1: do you attribute handedness to an animal, it's also difficult 371 00:21:37,160 --> 00:21:40,880 Speaker 1: to attribute handedness to a person because the idea of 372 00:21:40,920 --> 00:21:44,320 Speaker 1: whether or not you're left handed or right handed. Um, 373 00:21:44,560 --> 00:21:47,800 Speaker 1: it's still questionable, like if you write with your right hand, 374 00:21:48,440 --> 00:21:51,320 Speaker 1: but you actually can write better with your left hand 375 00:21:51,400 --> 00:21:55,119 Speaker 1: or something like that. Which what are you? Yeah, is 376 00:21:55,119 --> 00:21:57,400 Speaker 1: the one you're comfortable with, the one you that you're 377 00:21:57,400 --> 00:22:00,800 Speaker 1: actually better with. Yeah, that's a good point. Um. But 378 00:22:00,920 --> 00:22:04,920 Speaker 1: they have been looking at our our primate ancestors since 379 00:22:04,960 --> 00:22:07,959 Speaker 1: about the nineteen twenties, and they have found patterns. Um. 380 00:22:08,000 --> 00:22:13,240 Speaker 1: Apparently lemurs and are more left handed, and other prosim uh, 381 00:22:13,359 --> 00:22:17,560 Speaker 1: prosimians um. Macaques and old World monkeys for the most 382 00:22:17,600 --> 00:22:21,679 Speaker 1: part are evenly split, and guerrillas and chimpanzees are about 383 00:22:21,680 --> 00:22:26,000 Speaker 1: thirty five lefty. Um. But this is interesting. The more, 384 00:22:26,920 --> 00:22:29,960 Speaker 1: as they say here, the more primitive the primate, the 385 00:22:30,000 --> 00:22:33,800 Speaker 1: more likely it is to be a lefty, which goes 386 00:22:33,960 --> 00:22:40,399 Speaker 1: in the opposite of the gene mutation. It's the exact opposite. 387 00:22:40,040 --> 00:22:44,760 Speaker 1: It implies that we were originally left handed right as primates, 388 00:22:45,040 --> 00:22:47,680 Speaker 1: and then as we evolved we became right handed. So 389 00:22:47,880 --> 00:22:50,720 Speaker 1: therefore right handed people are more involved than left handed 390 00:22:50,720 --> 00:22:53,040 Speaker 1: people in some weird way. Yeah. So again it's another 391 00:22:53,080 --> 00:22:58,080 Speaker 1: inconsistency where and of course this is in primates too. Um. 392 00:22:58,160 --> 00:23:01,440 Speaker 1: That doesn't necessarily mean it's the same thing with you. No, 393 00:23:01,600 --> 00:23:04,000 Speaker 1: definitely not. But I mean, if you're looking at our 394 00:23:04,040 --> 00:23:06,800 Speaker 1: ancestry and trying to figure out where handedness came from, 395 00:23:06,920 --> 00:23:11,040 Speaker 1: you have to go pretty far back right, And I 396 00:23:11,520 --> 00:23:13,640 Speaker 1: that's a pretty good example of how this body of 397 00:23:13,920 --> 00:23:19,080 Speaker 1: work or knowledge is very contradictory. Still, yeah, it's baffling, 398 00:23:19,440 --> 00:23:23,240 Speaker 1: it's pretty awesome. Hey, Chuck, Hey, you sent me something 399 00:23:23,320 --> 00:23:26,479 Speaker 1: about um ambidextrous nous. Yeah. I thought this was kind 400 00:23:26,520 --> 00:23:29,960 Speaker 1: of interesting from mental flaws, like, like, it was just 401 00:23:30,040 --> 00:23:32,440 Speaker 1: kind of my understanding that anybody who said, oh, I'm 402 00:23:32,440 --> 00:23:34,680 Speaker 1: ambidextrous knew what they were talking about. But it turns 403 00:23:34,680 --> 00:23:38,000 Speaker 1: out that's really just not the case. For the most part. 404 00:23:38,320 --> 00:23:42,320 Speaker 1: It's a very rare um condition. I guess you'd call 405 00:23:42,359 --> 00:23:45,959 Speaker 1: it yeah, um, because I don't know if there is 406 00:23:46,000 --> 00:23:51,160 Speaker 1: a is a strict definition for what constitutes being ambidextrous. 407 00:23:51,240 --> 00:23:55,639 Speaker 1: Like a you know, a switch hitter in baseball doesn't 408 00:23:55,640 --> 00:23:58,800 Speaker 1: necessarily mean they're ambidextrous. It means they've taught themselves to 409 00:23:58,920 --> 00:24:02,320 Speaker 1: hit from the other side of the plate. Um. If 410 00:24:02,320 --> 00:24:05,960 Speaker 1: you notice, as a baseball fan, you're never gonna see 411 00:24:06,000 --> 00:24:10,520 Speaker 1: a player that hits uh equally as well on both sides. 412 00:24:11,200 --> 00:24:13,720 Speaker 1: Like you know, the great Chipper Jones here from Atlanta, 413 00:24:14,160 --> 00:24:16,040 Speaker 1: he favored one side of the plate. Although he was 414 00:24:16,080 --> 00:24:18,440 Speaker 1: a switch hitter, he was a much better hitter. I 415 00:24:18,440 --> 00:24:20,960 Speaker 1: think it was as a lefty and not as a righty. 416 00:24:21,480 --> 00:24:24,560 Speaker 1: So that's not image extrous now, someone who's taught themselves, 417 00:24:24,600 --> 00:24:28,119 Speaker 1: because it's a valuable skill in sports to be somewhat 418 00:24:28,160 --> 00:24:30,679 Speaker 1: embed extrous or in a lot of sports. UM. But 419 00:24:30,760 --> 00:24:33,280 Speaker 1: as far, I think writing is one of the things 420 00:24:33,320 --> 00:24:36,200 Speaker 1: that they can look at UM as a clear indicator 421 00:24:36,240 --> 00:24:40,120 Speaker 1: of which hand, uh you're you're best at And they 422 00:24:40,160 --> 00:24:43,040 Speaker 1: say about only about one percent can write equally as 423 00:24:43,040 --> 00:24:47,080 Speaker 1: well with either hand, So that's like super low UM 424 00:24:47,119 --> 00:24:51,720 Speaker 1: apparently too. So this handedness in this UM lateralization of 425 00:24:51,720 --> 00:24:54,160 Speaker 1: the brain and division of labor and all that has 426 00:24:54,160 --> 00:24:55,960 Speaker 1: a lot to do with how your brain is connected, 427 00:24:56,000 --> 00:24:58,639 Speaker 1: and apparently handedness is a part of that too. Yeah. 428 00:24:58,760 --> 00:25:02,840 Speaker 1: So like for example, UM, people who are ambidextrous UM 429 00:25:02,880 --> 00:25:07,680 Speaker 1: are more likely to suffer from schizophrenia, to have schizophrenia. 430 00:25:07,760 --> 00:25:11,760 Speaker 1: And there it's not just UM ambidextrous people. Apparently lefties 431 00:25:12,359 --> 00:25:17,760 Speaker 1: UM show a greater propensity towards schizophrenia. Something like people 432 00:25:17,800 --> 00:25:21,280 Speaker 1: with schizophrenia are left handed, which is a very high 433 00:25:21,320 --> 00:25:26,640 Speaker 1: proportion considering the general populations about ten and um. More 434 00:25:26,680 --> 00:25:31,080 Speaker 1: than that, dyslexia and stuttering as well, right, which suggests 435 00:25:31,119 --> 00:25:35,480 Speaker 1: that left handedness has an effect on how your brain 436 00:25:35,600 --> 00:25:38,760 Speaker 1: is wired. It's not just as simple, Oh my my 437 00:25:38,880 --> 00:25:42,040 Speaker 1: hand is I use my left hand. My my brain 438 00:25:42,119 --> 00:25:45,119 Speaker 1: is otherwise the exact same as a right handed person. 439 00:25:45,359 --> 00:25:49,480 Speaker 1: The brain does appear to be different in some ways, 440 00:25:49,960 --> 00:25:52,840 Speaker 1: especially in the ways that it's connected. Yeah. The um 441 00:25:52,960 --> 00:25:55,840 Speaker 1: we we talked about synesthesia before, one of our favorite 442 00:25:56,000 --> 00:26:00,480 Speaker 1: Uh what do you call it? A condition? Is it? Yeah? 443 00:26:00,920 --> 00:26:03,679 Speaker 1: Is it? Sure? I always just think of condition is 444 00:26:03,720 --> 00:26:09,840 Speaker 1: something that's uh, you know, derogatory. Yeah, like a malady 445 00:26:09,960 --> 00:26:12,879 Speaker 1: or something. I mean I think that falls under that 446 00:26:12,920 --> 00:26:15,840 Speaker 1: one is one, but the other one isn't necessarily that one. 447 00:26:16,080 --> 00:26:19,040 Speaker 1: So like a malady is a condition, but excipition isn't 448 00:26:19,040 --> 00:26:22,600 Speaker 1: necessarily a malady anyway. That's my long windway of saying. 449 00:26:22,600 --> 00:26:25,840 Speaker 1: Synist eats are awesome. Uh. And the rate of and 450 00:26:26,200 --> 00:26:29,360 Speaker 1: u ambidextrian synist eats is much higher, uh and left 451 00:26:29,400 --> 00:26:32,399 Speaker 1: handedness than in the general population. Right, So we have 452 00:26:32,480 --> 00:26:37,520 Speaker 1: some clues here, like UM, it's it's handedness has to 453 00:26:37,560 --> 00:26:39,480 Speaker 1: do with how your brain is wired, and if your 454 00:26:39,520 --> 00:26:41,800 Speaker 1: brain is wired in such a way that you are 455 00:26:41,920 --> 00:26:45,439 Speaker 1: left handed, your brain is wired differently from a person 456 00:26:45,480 --> 00:26:48,879 Speaker 1: with a right handed brain. Right, and a lot of 457 00:26:48,920 --> 00:26:50,879 Speaker 1: studies have backed that up and have come up with 458 00:26:50,960 --> 00:26:54,640 Speaker 1: things like, it's entirely possible that if you're a left 459 00:26:54,640 --> 00:26:58,120 Speaker 1: handed person you've got some advantages in life. We'll talk 460 00:26:58,160 --> 00:27:18,040 Speaker 1: about those right after this. So, Chuck, one of the 461 00:27:18,119 --> 00:27:23,280 Speaker 1: things that UM left handedness possibly bestows confers upon you 462 00:27:23,359 --> 00:27:26,919 Speaker 1: as a benefit is the idea of thinking quicker, to 463 00:27:26,960 --> 00:27:31,040 Speaker 1: be able to process information more quickly. Yeah. Uh, they 464 00:27:31,040 --> 00:27:34,879 Speaker 1: have done some studies on this. UM did did a 465 00:27:34,880 --> 00:27:37,160 Speaker 1: couple of studies, one of which UM they sat down 466 00:27:37,680 --> 00:27:40,399 Speaker 1: a hundred people, eighty right handers, twenty left handers and 467 00:27:40,440 --> 00:27:43,560 Speaker 1: basically to show them a computer screen with a single 468 00:27:43,600 --> 00:27:45,919 Speaker 1: dot either on the left or the right side, and 469 00:27:45,960 --> 00:27:48,680 Speaker 1: you had to press a button. It's just a speed test, basically, 470 00:27:49,359 --> 00:27:51,239 Speaker 1: like which side is it on? Left or right? Right? 471 00:27:51,280 --> 00:27:53,160 Speaker 1: So something shows up on the left side. I'm sure 472 00:27:53,160 --> 00:27:54,639 Speaker 1: you have a clicker in your left hand and clicker 473 00:27:54,640 --> 00:27:56,520 Speaker 1: in your right hand. You click the left hand clicker, 474 00:27:56,720 --> 00:27:59,679 Speaker 1: but this is all happening very fast. That's right. Um, 475 00:27:59,680 --> 00:28:03,480 Speaker 1: and left handed subjects were overall faster. Uh. And the 476 00:28:03,480 --> 00:28:05,600 Speaker 1: other tests they had to match up multiple letters that 477 00:28:05,640 --> 00:28:08,760 Speaker 1: appeared in some cases on either side of the line 478 00:28:08,800 --> 00:28:11,760 Speaker 1: and in other cases on just one side. And again 479 00:28:11,960 --> 00:28:15,720 Speaker 1: left handed, Uh, we're faster, but just at matching letters 480 00:28:15,720 --> 00:28:18,320 Speaker 1: that were on both sides of the line, right, which 481 00:28:18,320 --> 00:28:21,040 Speaker 1: I thought was interesting well, and that supports this idea 482 00:28:21,160 --> 00:28:25,880 Speaker 1: that um, the the brain. The fact that um, some 483 00:28:26,080 --> 00:28:31,040 Speaker 1: left handed people's motor skills and language centers are on 484 00:28:31,160 --> 00:28:36,520 Speaker 1: different sides in their brains, uh, could make them talk more. 485 00:28:36,920 --> 00:28:40,160 Speaker 1: The side of their hemispheres of their brains are more connected, 486 00:28:40,200 --> 00:28:43,600 Speaker 1: there's more white tissue where their corpus colossum is more efficient. 487 00:28:44,040 --> 00:28:46,920 Speaker 1: It makes sense in a way, but at the same 488 00:28:46,960 --> 00:28:49,360 Speaker 1: time you're like, wait, that doesn't make any sense. So 489 00:28:49,600 --> 00:28:52,760 Speaker 1: it's kind of this data should be taken and just 490 00:28:52,840 --> 00:28:55,520 Speaker 1: locked away in a box until we understand the whole 491 00:28:55,520 --> 00:28:58,640 Speaker 1: thing more, because it doesn't really do do a lot 492 00:28:58,680 --> 00:29:00,600 Speaker 1: at this point. We don't know enough to make it fit. 493 00:29:01,480 --> 00:29:04,040 Speaker 1: And it's actually kind of contradictory to some other stuff 494 00:29:04,080 --> 00:29:07,120 Speaker 1: too as far as handedness goes. Yeah, but they do 495 00:29:07,200 --> 00:29:08,920 Speaker 1: say that if you're left handed, you may be like 496 00:29:08,960 --> 00:29:13,840 Speaker 1: a better gamer or or a pilot, because you're able 497 00:29:13,880 --> 00:29:18,480 Speaker 1: to just process this quick information super fast, like rapid 498 00:29:18,480 --> 00:29:21,400 Speaker 1: fire stuff coming at you. It also suggested to that 499 00:29:21,560 --> 00:29:25,240 Speaker 1: language can be processed in both hemispheres among left handed people, 500 00:29:25,760 --> 00:29:29,240 Speaker 1: which again would require a lot more connections between the 501 00:29:29,320 --> 00:29:35,840 Speaker 1: two hemispheres, faster communication between the two and hence quicker thinking. Yeah, 502 00:29:35,920 --> 00:29:37,840 Speaker 1: and that you in the long run, as you age 503 00:29:37,920 --> 00:29:40,080 Speaker 1: in your brain deteriorates, you may be in better shape 504 00:29:40,120 --> 00:29:44,240 Speaker 1: as a lefty because your other hemisphere may be able 505 00:29:44,280 --> 00:29:47,400 Speaker 1: to pick up that slack more easily. Whereas if you're 506 00:29:47,440 --> 00:29:51,360 Speaker 1: just a dumb right hander, you're just you know, screwed, 507 00:29:51,880 --> 00:29:54,360 Speaker 1: You're in You're in trouble. And of course this has approven. 508 00:29:54,360 --> 00:29:58,040 Speaker 1: This is just there postulating here, right, But I mean, 509 00:29:58,120 --> 00:30:01,920 Speaker 1: as to this mystery, Yeah, you definitely haven't an advantage 510 00:30:01,920 --> 00:30:04,960 Speaker 1: in sports in a lot of cases. Though, Yes, but 511 00:30:05,280 --> 00:30:08,280 Speaker 1: not in the way that you would think. It's not 512 00:30:08,360 --> 00:30:11,800 Speaker 1: necessarily because your brain is communicating. The hemispheres are of 513 00:30:11,840 --> 00:30:15,040 Speaker 1: your brain are communicating. It's more because your opponent is 514 00:30:15,040 --> 00:30:18,640 Speaker 1: statistically likelier to be expecting you to be a right 515 00:30:18,680 --> 00:30:21,560 Speaker 1: handed person to have trained against the right handed person 516 00:30:22,600 --> 00:30:25,920 Speaker 1: exactly to be used to playing a right handed person. 517 00:30:25,920 --> 00:30:28,320 Speaker 1: Whereas if you're a left handed person, they're playing you. Now, 518 00:30:28,600 --> 00:30:31,400 Speaker 1: you're going to throw them off guard. You're gonna catch 519 00:30:31,480 --> 00:30:33,040 Speaker 1: them off guard. You're gonna be able to get the 520 00:30:33,120 --> 00:30:35,600 Speaker 1: drop on them because they're not used to you. Whereas you, 521 00:30:35,920 --> 00:30:39,800 Speaker 1: being a lefty, you're still statistically likelier to have played 522 00:30:40,000 --> 00:30:42,720 Speaker 1: right handed people, so you know how to handle them. 523 00:30:42,960 --> 00:30:45,760 Speaker 1: They don't know how to handle you. You're the wild card, baby, 524 00:30:46,120 --> 00:30:50,920 Speaker 1: you win your Rocky. Yeah, Rocky was left handed. Apparently. Um, 525 00:30:50,960 --> 00:30:54,480 Speaker 1: and there's a bunch of sports figures in real life 526 00:30:54,520 --> 00:30:57,160 Speaker 1: that we're left handed, and apparently it's one of those 527 00:30:57,160 --> 00:31:01,440 Speaker 1: things where they're disproportionately represented. Yeah, as far as successful 528 00:31:01,480 --> 00:31:05,560 Speaker 1: athletes go compared to the to the population at large. Yeah, 529 00:31:05,640 --> 00:31:07,480 Speaker 1: and I think, um, a lot of times you'll hear 530 00:31:07,480 --> 00:31:10,520 Speaker 1: about like m M A or boxing. Tennis is another 531 00:31:10,560 --> 00:31:13,400 Speaker 1: big one because if you're used to playing right e's 532 00:31:13,440 --> 00:31:16,240 Speaker 1: most of your life, that left handed server comes up 533 00:31:16,280 --> 00:31:18,920 Speaker 1: there and it's it's different, it's weird, right, And the 534 00:31:19,360 --> 00:31:21,480 Speaker 1: difference is so pronounced that, like if you are a 535 00:31:21,480 --> 00:31:24,080 Speaker 1: pro tennis player or something like that or pro boxer. 536 00:31:24,320 --> 00:31:28,440 Speaker 1: You're gonna train against the lefty before a match against 537 00:31:28,440 --> 00:31:31,080 Speaker 1: the lefty. Yeah, you know, you're gonna do what you 538 00:31:31,120 --> 00:31:33,680 Speaker 1: can to prepare yourself. Yeah. And I think Robert Lamb 539 00:31:33,720 --> 00:31:36,400 Speaker 1: wrote this on how staff forks are left handers quicker, 540 00:31:36,800 --> 00:31:40,520 Speaker 1: I'm sorry, better at sports and um. He also points 541 00:31:40,520 --> 00:31:43,760 Speaker 1: out that through history, uh, this probably comes from like 542 00:31:43,800 --> 00:31:48,480 Speaker 1: soldier training, mainly training and fighting and jousting and sword 543 00:31:48,560 --> 00:31:51,479 Speaker 1: fighting and everything against other right e's as well, So 544 00:31:51,520 --> 00:31:54,720 Speaker 1: a lefty would have a left handed warrior might be 545 00:31:54,800 --> 00:31:57,239 Speaker 1: more prone to be, you know, the great leader, like 546 00:31:57,480 --> 00:32:00,960 Speaker 1: perhaps Alexander the Great right who was a left handed 547 00:32:01,200 --> 00:32:03,520 Speaker 1: What's weird though, is if that has been the case, 548 00:32:04,240 --> 00:32:08,280 Speaker 1: if humans have been left handed and right handed, the 549 00:32:08,280 --> 00:32:10,200 Speaker 1: proportions have been roughly the same for the last two 550 00:32:10,280 --> 00:32:15,080 Speaker 1: hundred thousand years. If you're left handed combatant, wouldn't then 551 00:32:15,120 --> 00:32:18,920 Speaker 1: the proportion of left handed people have grown over time 552 00:32:19,040 --> 00:32:23,120 Speaker 1: because of natural selection because you you have an advantage 553 00:32:23,160 --> 00:32:25,960 Speaker 1: in battle or something like that. So therefore the population 554 00:32:26,000 --> 00:32:28,280 Speaker 1: of right handed people would drop in relation to the 555 00:32:28,280 --> 00:32:31,840 Speaker 1: population of left exactly. That makes sense. And I remember this, 556 00:32:31,960 --> 00:32:36,080 Speaker 1: but that hasn't happened. Yeah, I remember our podcasts on 557 00:32:36,160 --> 00:32:41,400 Speaker 1: castles like eighty years ago. Remember they built the staircases 558 00:32:42,400 --> 00:32:45,560 Speaker 1: going on the right hand side. I can't even do 559 00:32:45,600 --> 00:32:49,160 Speaker 1: you remember how mine fending lee difficult? That was for 560 00:32:49,200 --> 00:32:51,800 Speaker 1: me to understand. Did you have our time with Oh? Yeah, 561 00:32:52,040 --> 00:32:54,480 Speaker 1: we had to re record it I think twice because 562 00:32:54,520 --> 00:32:56,840 Speaker 1: I kept getting it wrong. Yeah. We also got in 563 00:32:56,880 --> 00:33:00,240 Speaker 1: trouble for for a cussword in that one too. Those 564 00:33:01,040 --> 00:33:04,640 Speaker 1: that was a dark day many years ago. Um. Yeah, 565 00:33:04,680 --> 00:33:06,959 Speaker 1: but the Yeah, the the castle steps would wind up 566 00:33:06,960 --> 00:33:08,760 Speaker 1: on the right side of the wall to give the 567 00:33:08,800 --> 00:33:12,960 Speaker 1: advantage to the person higher on the stairs swinging a 568 00:33:13,080 --> 00:33:15,800 Speaker 1: right handed sword because obviously you couldn't swing a right 569 00:33:15,840 --> 00:33:18,120 Speaker 1: handed sword going up the stairs because the wall is 570 00:33:18,120 --> 00:33:24,320 Speaker 1: on your right. But a left handed combatant advantage taken 571 00:33:24,360 --> 00:33:28,120 Speaker 1: away even though you have the higher ground, because all 572 00:33:28,120 --> 00:33:30,920 Speaker 1: of a sudden you're cutting the guy's knees off. They 573 00:33:30,920 --> 00:33:32,800 Speaker 1: were cutting them off at the knees. Yeah, you know 574 00:33:33,120 --> 00:33:38,000 Speaker 1: that hurts. It does. But also included with natural selection 575 00:33:38,040 --> 00:33:41,320 Speaker 1: two is if there were any real disadvantages to being 576 00:33:41,680 --> 00:33:44,680 Speaker 1: a left handed person, or there were advantages to being 577 00:33:44,680 --> 00:33:48,680 Speaker 1: a right handed person, this population shouldn't have remained steady 578 00:33:48,760 --> 00:33:51,040 Speaker 1: over that long of a period too. I see what 579 00:33:51,080 --> 00:33:53,840 Speaker 1: you mean, you know, unless the advantage isn't so great 580 00:33:53,920 --> 00:33:58,520 Speaker 1: as to you know, cause uh, that natural selection to occur, 581 00:33:59,640 --> 00:34:03,680 Speaker 1: you know. Maybe. Um, there are more US presidents that 582 00:34:03,720 --> 00:34:07,120 Speaker 1: have been left handed, more MENSA members for whatever that's worth. 583 00:34:07,680 --> 00:34:10,719 Speaker 1: Half half of the twelve US presidents, so it's World 584 00:34:10,760 --> 00:34:14,239 Speaker 1: War two have been left handed. So whereas the normal populations, 585 00:34:14,280 --> 00:34:17,399 Speaker 1: ten or fifteen percent lefties US presidents of World War 586 00:34:17,440 --> 00:34:23,799 Speaker 1: two has been And apparently in the campaign all three 587 00:34:23,840 --> 00:34:29,040 Speaker 1: candidates H. W. Bush, Clinton, and Pero were left handed. Yeah, 588 00:34:29,040 --> 00:34:32,239 Speaker 1: that's a percent of the population. Peroh man, he was 589 00:34:32,280 --> 00:34:36,200 Speaker 1: fun to watch. He was Dana Carvey was fun to 590 00:34:36,200 --> 00:34:39,160 Speaker 1: watch doing Pero too. Oh yeah. Uh. And they say 591 00:34:39,480 --> 00:34:42,640 Speaker 1: more musicians more or musicians are more likely to be 592 00:34:42,719 --> 00:34:46,400 Speaker 1: left handed. Maybe, um. And it does run in families, 593 00:34:47,000 --> 00:34:51,040 Speaker 1: even though identical twins can have opposite hand preferences. Oh weird, 594 00:34:51,440 --> 00:34:54,000 Speaker 1: And um there is In the nineteen eighties, it was 595 00:34:54,040 --> 00:34:59,399 Speaker 1: a Harvard neurologist that said that, ah, lefties are right 596 00:34:59,440 --> 00:35:03,799 Speaker 1: eas whose brain centers in the womb change because of 597 00:35:04,360 --> 00:35:08,440 Speaker 1: high testosterone. Yeah, so there's there's theories that we become 598 00:35:08,480 --> 00:35:11,520 Speaker 1: handed in the womb because of something like that, or 599 00:35:11,640 --> 00:35:14,480 Speaker 1: birth trauma or some sort of trauma while we're in 600 00:35:14,480 --> 00:35:18,000 Speaker 1: the womb and that, Yeah, it just adjusts the the 601 00:35:18,000 --> 00:35:23,040 Speaker 1: the construction of our brains. Um. Supposedly, a mother's age 602 00:35:23,080 --> 00:35:27,920 Speaker 1: has an impact on her kids. That's crazy. Statistically speaking, 603 00:35:28,160 --> 00:35:33,279 Speaker 1: a mother UM over forty who gives birth is has 604 00:35:33,320 --> 00:35:36,000 Speaker 1: a higher likelihood of having a lefty kid, way higher, 605 00:35:36,040 --> 00:35:39,719 Speaker 1: like h or something. Yeah, like that's pretty high. Yeah, 606 00:35:40,040 --> 00:35:43,320 Speaker 1: it's more than I don't even know what that means. Yeah, 607 00:35:43,360 --> 00:35:47,399 Speaker 1: and then I guess your hand preference emerges about by 608 00:35:47,480 --> 00:35:51,360 Speaker 1: seven months, but then it's like set by age three, 609 00:35:51,640 --> 00:35:54,000 Speaker 1: So before seven months you're just flinging poop with both 610 00:35:54,000 --> 00:35:56,880 Speaker 1: hands equally as well. Pretty much. Yeah. I wrote a 611 00:35:56,880 --> 00:35:59,360 Speaker 1: story about a guy who found out as an adult 612 00:35:59,440 --> 00:36:02,719 Speaker 1: that has mother had suspected he was left handed when 613 00:36:02,760 --> 00:36:07,279 Speaker 1: he was a baby, so she immobilized his left hand 614 00:36:07,400 --> 00:36:09,400 Speaker 1: so that he would be forced to learn with his 615 00:36:09,520 --> 00:36:12,799 Speaker 1: right hand. He didn't seem to take it like that, 616 00:36:12,840 --> 00:36:15,359 Speaker 1: but he did see it came across like he felt 617 00:36:15,400 --> 00:36:17,480 Speaker 1: like something had been kind of taken from him. He 618 00:36:17,520 --> 00:36:19,960 Speaker 1: said it also explained a lot that he was like 619 00:36:20,360 --> 00:36:23,720 Speaker 1: so so with stuff that involves its right hand seemed 620 00:36:23,760 --> 00:36:26,560 Speaker 1: to be better with his left and um that he 621 00:36:26,680 --> 00:36:28,800 Speaker 1: looked into it, and that by doing that, which is 622 00:36:28,920 --> 00:36:32,760 Speaker 1: very popular, like kids were forced to become right handed 623 00:36:32,840 --> 00:36:38,760 Speaker 1: through the twentieth century. Um that you are basically making 624 00:36:38,960 --> 00:36:45,320 Speaker 1: a a less pronounced copy of the person. You're taking 625 00:36:45,360 --> 00:36:49,040 Speaker 1: the original and making like a slightly dimmer effect simile 626 00:36:49,160 --> 00:36:52,239 Speaker 1: of it, like forcing their being to reorganize like that 627 00:36:52,760 --> 00:36:55,640 Speaker 1: interesting whereas they thought they were trying to give them 628 00:36:55,640 --> 00:36:58,160 Speaker 1: an advantage, to actually give them a disadvantage exactly. But 629 00:36:58,440 --> 00:37:01,680 Speaker 1: I would imagine that if you did that till say 630 00:37:02,080 --> 00:37:05,440 Speaker 1: age eighteen, and then all of a sudden started using 631 00:37:05,440 --> 00:37:08,239 Speaker 1: your dominant hand that you were naturally born with. It's 632 00:37:08,280 --> 00:37:10,640 Speaker 1: all like Spinley in week right, but then once you 633 00:37:10,680 --> 00:37:14,080 Speaker 1: once you train it to to to bulk back up. Yeah, 634 00:37:14,600 --> 00:37:17,959 Speaker 1: I would imagine your brain would would be better off 635 00:37:18,000 --> 00:37:21,640 Speaker 1: like that, be fuller. So to continue the abuse right 636 00:37:21,719 --> 00:37:25,680 Speaker 1: until eighteen, discontinued the abuse, and then bam, you got 637 00:37:25,680 --> 00:37:27,719 Speaker 1: a super kid on your take your little old man 638 00:37:27,840 --> 00:37:30,799 Speaker 1: Spinley hands and fingers like, um, build them back up 639 00:37:30,880 --> 00:37:36,160 Speaker 1: and Mr Show character remember Titanico and they were crossed 640 00:37:36,200 --> 00:37:40,200 Speaker 1: in the hospital. You know they're getting back together. Yeah, yeah, 641 00:37:40,320 --> 00:37:44,840 Speaker 1: that's exciting. So p FT tweeted something some picture is 642 00:37:44,960 --> 00:37:47,799 Speaker 1: very exciting, the whole gang. If you want to know 643 00:37:47,840 --> 00:37:51,200 Speaker 1: more about Paul if Tompkins or Handedness or Mr Show 644 00:37:51,280 --> 00:37:53,600 Speaker 1: or any of that jazz, you can type that stuff 645 00:37:53,640 --> 00:37:56,400 Speaker 1: into the search bar at how stuff works dot com. 646 00:37:56,440 --> 00:38:01,839 Speaker 1: Since I said search parts, time for listener mail, I'm 647 00:38:01,840 --> 00:38:05,359 Speaker 1: gonna call this Christian shout out.
