Speaker 1: Welcome to Stuff to Blow your Mind from how Stuff
Speaker 1: Works dot com. Hey, welcome to Stuff to Blow your Mind.
Speaker 1: My name is Robert lamb Man. I'm Julie Righty Douglas.
Speaker 1: That's right. I'm right handed as well. This is a
Speaker 1: right handed podcast. Now, technically Noel, who records this is
Speaker 1: left handed, but this is a right handed podcast, so
Speaker 1: we forced him to use his only his right hand
Speaker 1: and left is down behind him at all times, at
Speaker 1: least when he's recording us. I don't care what that
Speaker 1: other podcasts do, but darnet, we have standards here. We do. Yeah,
Speaker 1: we're keeping it right and tight all the time. Yeah,
Speaker 1: because what we're firm believers that left handed individuals are debased,
Speaker 1: their evil to freaks of nature, and they should be
Speaker 1: distrusted at least and re educated along the right path
Speaker 1: whenever possible. I mean, that's why we have the rule
Speaker 1: of left hand behind the back in the podcast booth.
Speaker 1: I mean, my wife is was born left handed. She's
Speaker 1: right handed now because we have that corrected, and and
Speaker 1: I love her, but I love her because you know,
Speaker 1: we corrected what was wrong with it. Yeah. Well, you
Speaker 1: know my husband is left handed, and uh, every once
Speaker 1: in a while, I will catch him using it. And
Speaker 1: our daughter's ambidextrous, and that's frowned upond as well. Yeah,
Speaker 1: well but that can be that can be fixed over time.
Speaker 1: We're trying, we're trying to firm with the discipline on
Speaker 1: everybody in your life that is tempted to use their
Speaker 1: left hand for for anything important. Yeah, so keep that
Speaker 1: in mind as you guys are listening, whether or not
Speaker 1: you're a righty or a lefty. Yes, it can be corrected. Now.
Speaker 1: Of course, we're having a little fun here with with
Speaker 1: our lefties, because of course there are all sorts of
Speaker 1: stories about the left. Left handedness signifies evil, and left
Speaker 1: handedness is wrong. And certainly we have created a right
Speaker 1: handed world because the vast majority of individuals are right handed.
Speaker 1: Only ten percent of the population is actually left handed.
Speaker 1: And and and in reality, there's nothing evil about you guys.
Speaker 1: But I love poking fun because everyone knows that this
Speaker 1: is not true. But but when you when you start
Speaker 1: prodding and poking the left andy's about this, they sometimes
Speaker 1: get a little up in arms. Well it's true, because
Speaker 1: I mean, think about it, you're pretty much outnumbered everybody
Speaker 1: else using it right hand you're forced to use the
Speaker 1: scissors that are awkward and bunched up, and all sorts
Speaker 1: of different ways that you're navigating the world in which
Speaker 1: you have to try to fit in to this right
Speaker 1: hand world. Yeah. But but as we'll discuss in this episode,
Speaker 1: left handedness brings with it its share of benefits in
Speaker 1: addition to its many curses. Now, you guys might have
Speaker 1: the upper advantage. Actually, yeah, certainly literally the upper hand,
Speaker 1: the upper left hand advantage. Um. So, by the way,
Speaker 1: I wanted to point out that you guys have been
Speaker 1: ten percent of the population for a really, really long time.
Speaker 1: And this is according to Perry Class, writing for the
Speaker 1: New York Times, the size of the South Paw population
Speaker 1: has held constant ever since hunter gatherer days. And this
Speaker 1: is data that comes from studies of cave paintings and
Speaker 1: archaeological analysis of ancient artifacts and how they were used.
Speaker 1: So we know that for what at least ten fifteen
Speaker 1: thousand years at the very least, that this has been
Speaker 1: going on. Of course, you know, the human species extents
Speaker 1: well beyond that. But right now we know you guys
Speaker 1: have been the minority for a while. Now. It is interesting,
Speaker 1: and we'll discuss the reason for this shortly, in some
Speaker 1: areas where it's particularly a war torn where there's a
Speaker 1: lot of violence going on, you'll sometimes see that the
Speaker 1: number of left handed individuals increase. And this is this
Speaker 1: is due not to the fact that left hand needs
Speaker 1: are evil and then if there are more in an area,
Speaker 1: it makes that area more prone to violence. But it
Speaker 1: comes down to having a left handed advantage, supposedly in combat,
Speaker 1: and we'll talk about that. We'll talk about why being
Speaker 1: left handed is actually an advantage um not just in
Speaker 1: in uh cognition, but also in warfare and other sports.
Speaker 1: According to a two thousand and eight study, a meta
Speaker 1: analysis of one forty four studies, that's a lot which
Speaker 1: included one point so than million people. It's a lot
Speaker 1: of people. To men have one point two three times
Speaker 1: the odds of being left handed compared to win the chances.
Speaker 1: So if you are a lefty woman and you're super
Speaker 1: in the minority, which is weird because it seems like
Speaker 1: I'm around a lot of left handed ladies, Like my
Speaker 1: wife is left handed, my sister is left handed, and
Speaker 1: we have at least a couple of lefty ladies here
Speaker 1: in the office. It's true, you should probably examine. I'm
Speaker 1: not going to out them, really, I don't know to
Speaker 1: what extent there. Well, I think they're proud, Are they proudly? Yeah,
Speaker 1: lefties tend to be proud these days. And then well
Speaker 1: they should be Alison labor Milk, Christine Conder. Yeah, it's
Speaker 1: not gonna be like they can hide it because you're
Speaker 1: inevitably gonna have to go to a dinner and you're
Speaker 1: gonna be bumping elbows with the right. Yeah, that's my
Speaker 1: chief complaint. I have to say with my husband, we
Speaker 1: always have to make sure we're in the right position
Speaker 1: eating dinner position, that's right. See, mother's over forty are
Speaker 1: one percent more likely to give birth to a lefty
Speaker 1: than younger mom in their twenties, and only about one
Speaker 1: percent of the population is truly ambidextrous. And this is
Speaker 1: according to Live Sciences article south Paw Stats. Now, when
Speaker 1: they say truly ambidextrous, what we're talking about here is
Speaker 1: that there's a kind of spectrum of handedness, and so
Speaker 1: people may be a little bit left handed or very
Speaker 1: left handed on the spectrum, and it kind of reminds
Speaker 1: me of the Kinsey Scale of sexuality. People heavily identify
Speaker 1: as homosexual orsexual. There's a lot of room in between.
Speaker 1: There's a sliding scale, and you're not necessarily going to
Speaker 1: be one extreme or the other, but somewhere on that scale.
Speaker 1: And the same host for left handedness and and the
Speaker 1: and uh and behmbidextrous. That's true. All right, Let's talk
Speaker 1: about genetics, because lefties, I feel like are often given
Speaker 1: really short shrift in this area because there's an association
Speaker 1: of increased cases of schizophrenia a d D and dyslexia
Speaker 1: with left handedness. Yeah, and a lot of this comes
Speaker 1: down to l r r t M one. That's the
Speaker 1: specific gaine that's passed on from the father that tends
Speaker 1: to increase the chances of someone being left handed, and
Speaker 1: the same gene seems to confer slightly increased chance of
Speaker 1: schizophrenia slightly slightly. Yeah. And by the way, this was
Speaker 1: a study on dyslexic children, so I thought that was
Speaker 1: kind of interesting. They weren't necessarily going after and trying
Speaker 1: to figure out an association with it. It wasn't funded
Speaker 1: by the by the the lefty support organizations or the
Speaker 1: or the righty power organizations. That's right, wasn't funded by
Speaker 1: the right. Um, So you have something called dextral or
Speaker 1: chance genes. And according to Claire poor Act she's a
Speaker 1: professor of psychology at Penn State Theory, humans are born
Speaker 1: with two genes for handedness. So you either have dexterral
Speaker 1: or chance, and the dominant dextral gene induces right handedness
Speaker 1: whenever it turns up. But if there are two pairs
Speaker 1: of chance genes, then that is when you become more
Speaker 1: prone to becoming a lefty. Now, all of this being said,
Speaker 1: there is an environmental factor here as well, so it's
Speaker 1: not just coming down to janea um. Consider that identical
Speaker 1: twins often have dominant hands, and this is according to
Speaker 1: a Violin Lorens and evolutionary biologists. So even twins could
Speaker 1: be differently handed, which makes sense because one can be
Speaker 1: like the reflection of the other, right ones, the evil
Speaker 1: twin once the good twins exact. Right, Well, I'm wonder
Speaker 1: which one is the evil one? Now this is interesting, uh,
Speaker 1: and this one we can just getting out of the
Speaker 1: schizophrenic area and into some of the positives. Lefties, they say,
Speaker 1: tend to have a more balanced view of their bodies,
Speaker 1: and that's because when asked to the angel visualized space.
Speaker 1: A righty tends to be more sensitive to their right side,
Speaker 1: uh and their left side is more like a like
Speaker 1: a t rex little arm, you know, so like imagine,
Speaker 1: you know, we've all seen the homunculous, not the real
Speaker 1: homunculous that a wizard bruise up, but the one that
Speaker 1: represents our body image in our sense organs and and
Speaker 1: and basically the shape of our body as as internalized
Speaker 1: and sense. Like if we were to look at the
Speaker 1: way a righty views their body, it would be, you know,
Speaker 1: a very right hand dominated like a giant right right
Speaker 1: arm and then like a tiny left arm, like they're
Speaker 1: very very lopsided, whereas a lefty tends to uh not
Speaker 1: have that kind of bias. And this comes from a
Speaker 1: lifetime of having to deal with all the right handed
Speaker 1: stuff in our world. So they're having to deal with
Speaker 1: all of this right handed stuff, but they're actually left handed,
Speaker 1: so the to kind of cancel each other out and
Speaker 1: right the ship right, and which makes it makes sense
Speaker 1: that there's more spatial awareness and could possibly be one
Speaker 1: of the reasons why a lot of lefties tend to
Speaker 1: be engineers, because there are people who can deal with
Speaker 1: spatial reasoning really really well. Um, and a lot of
Speaker 1: this has to do not just with spacial reasoning, but
Speaker 1: just your processing your motor skills, also language processing. But
Speaker 1: going back to motor skills, just wanted to lay out
Speaker 1: there that the nerves connect our hands to the areas
Speaker 1: of the brain responsible for motor skills. So there's a
Speaker 1: separate set for each hand, but the wiring is crossed,
Speaker 1: so you're right hand is hooked up to the left
Speaker 1: side of the brain and vice versa. But when you
Speaker 1: look at left east, they're taking in data and they're
Speaker 1: they're really bi cerebral if you think about it, because
Speaker 1: they are factoring in particularly language in both hemispheres, whereas
Speaker 1: right eas are processing language in the left hemisphere. So
Speaker 1: as a result of the corpus close and we've talked
Speaker 1: about this this little guy before, it's a part of
Speaker 1: that connects to both hemispheres. Is about eleven larger and
Speaker 1: left handed brains than right handed brains. And this is
Speaker 1: this idea that it's actually aiding the left east to
Speaker 1: be quicker on the uptake of information and processing it.
Speaker 1: All Right, we're gonna take a break and when we
Speaker 1: come back, we're gonna deal more with left handed individuals
Speaker 1: about why you might want to think twice about getting
Speaker 1: into it. It's fight with one all right, we're back.
Speaker 1: We're talking about lefties. And if you engaged in sports
Speaker 1: or fist fights, or sports and fist fights or fist
Speaker 1: fights that are actually a form of sports, there's a
Speaker 1: chance you're gonna come up against the lefty at some point.
Speaker 1: They're only ten of the population. But when you start
Speaker 1: looking at some of the big names in sports, you
Speaker 1: look at Adam Palmer, you look at Bobby Or, you
Speaker 1: look at John McEnroe, Oscar de la Hoya, and Babe Ruth.
Speaker 1: Even though Babe Ruth supposedly wrote right handed, these were
Speaker 1: all lefties. These were all people at the top of
Speaker 1: their sport and they were doing it with the left hand. Yeah.
Speaker 1: And as you had mentioned that lefties living in the
Speaker 1: right hand world, they have much more spatial awareness on
Speaker 1: both sides. Right And according to Melissa Rough in her
Speaker 1: book The Left Stuff, bio mechanical research has revealed that
Speaker 1: training the non dominant side of the body can actually
Speaker 1: enhance the dominant side, and this is known as the
Speaker 1: cross training effect, and the body's neural network is integrated
Speaker 1: on both sides, which would confer an advantage already, right, right,
Speaker 1: And then if you're you're training to do from you know,
Speaker 1: to combat other individuals, say with swords, with with pointed sticks,
Speaker 1: or in engaging to to fight against some in a
Speaker 1: boxing match or in tennis, you're going to more likely
Speaker 1: you're gonna train mostly to deal with the population, unless
Speaker 1: you're you're saying I'm only going to box schizophrenics, in
Speaker 1: which case you're gonna deal with of that population is
Speaker 1: left handed. Actually due to the slightly higher chances that
Speaker 1: we talked about earlier population of lefties. Yes, yes, yeah,
Speaker 1: so most of your training is going to revolve around
Speaker 1: fighting other rightings or even if you're a lefty, you're
Speaker 1: going to be more predisposed to fight right eas But
Speaker 1: then when you deal with a lefty, it's going to
Speaker 1: potentially skew things just a little bit because their hand
Speaker 1: dominance is gonna be gonna be different, uh there, and
Speaker 1: their training is going to be different. It throws things
Speaker 1: out of whack. And we see this in the natural
Speaker 1: world too, right. We see this with sea snails that
Speaker 1: actually the shape of their shell are coiled counter clockwise
Speaker 1: or left as opposed to the more typical clockwise arrangement.
Speaker 1: Now why is this useful, Well, it's because right claude
Speaker 1: predator crabs are used to kind of can opening them
Speaker 1: right with their with their claws, but they come upon
Speaker 1: a sea snail who's a lefty with a counterclockwise swirl
Speaker 1: or configuration to their shell and they can't get in
Speaker 1: there and crack them open. Yeah, they have evolved to
Speaker 1: eat right e's and then when a lefty presents itself,
Speaker 1: they can't cope with it. They have their their form
Speaker 1: is not suitable to this altered form. Would like a
Speaker 1: righty in in the um the boxing match with the
Speaker 1: lefty right exactly can't really anticipate how this is going
Speaker 1: to play out. Yeah, now that's that's why a boxer
Speaker 1: knows that he or she is going up against a lefty,
Speaker 1: then they'll intensify their training, uh with a with a
Speaker 1: left handed sparring partner, because because again the percentage is there.
Speaker 1: You can't go if you're a professional boxer, if you're
Speaker 1: a professional tennis player, if you're just they do with
Speaker 1: a sword in a on a medieval battlefield, chances are
Speaker 1: you're going to encounter that left handed individual at some point,
Speaker 1: and you don't want to just be completely decimated by
Speaker 1: then when it happens. But even that, even the training
Speaker 1: is not going to give you the advantage that lefties
Speaker 1: have with the processing right. With the cognitive processing, study
Speaker 1: leader Dr Nick Turban from the Australian National University took
Speaker 1: left handed and right handed people and recorded the transfer
Speaker 1: time between the two sides of the brain. And he
Speaker 1: did this through measuring reaction times, and reaction times being
Speaker 1: huge in sports. UH two white dots flashed to the
Speaker 1: left and right of a fixed cross configuration on their screen.
Speaker 1: He compared this with how good participants were carrying out
Speaker 1: the task to spot matching letters in the left and
Speaker 1: right visual fields, which will require them to use the
Speaker 1: same parts of the brain at the same time. Um
Speaker 1: extreme left handed individuals, those people in the spectrum extreme
Speaker 1: lefties were forty three milliseconds faster at spotting matching letters
Speaker 1: across the right and left visual fields than their right
Speaker 1: handed compatriots. So again you're talking about a more symetrical brain,
Speaker 1: a larger corpus clos um transmitting that information. So even
Speaker 1: if someone is swinging at you and you've trained against them, um,
Speaker 1: and you swing against them, they're they're taking in the
Speaker 1: data quicker than you are. Well. Um. I mentioned earlier
Speaker 1: about how war torn areas you might see an increase
Speaker 1: in the number of left handed individuals in your myths,
Speaker 1: and this comes back to a study from Para French
Speaker 1: researchers uh Charlotte Foi and Michael Raymond. This is between
Speaker 1: two thousand and one and two thousand four. They tested
Speaker 1: the theory of lefty battle supremacy by examining the prevalence
Speaker 1: of left handed citizens in area with areas with high
Speaker 1: murder rates, because in theory, these conditions would allow them
Speaker 1: a better chance to observe at least statistically the left,
Speaker 1: the lefty survival of the fist. And sure enough they
Speaker 1: found that lefty population percentages in these areas win as
Speaker 1: high as twenty seven percent, so again up from ten
Speaker 1: percent of the population to because there's that much face
Speaker 1: stabbing going on that the lefty face stabbers are going
Speaker 1: to actually sustain their population, whereas the righties are going
Speaker 1: to die of their face wins. Okay, so you have
Speaker 1: some negative connotations of like schizophrenia, dyslexia, and so on
Speaker 1: and so forth, but now you have criminality added to
Speaker 1: It's just the culture itself is falling into criminality and
Speaker 1: falling into violence. And you can't blame the lefties for
Speaker 1: just being better at stabbing people in the face. That's
Speaker 1: just that's just a fact, right, But an unintended consequence
Speaker 1: might be that those lefties watch out, they're gonna shrank yea, yeah,
Speaker 1: I mean its survival of the Fittestralia. Well, okay, so
Speaker 1: that's playing to this idea though, that that lefties are
Speaker 1: inherently sinister. Yeah, there's something off about them, that their
Speaker 1: their skills seem a little better. And we can either
Speaker 1: chalk that up to again the inner workings of their
Speaker 1: rain and how they have to to to deal with
Speaker 1: a righty world, or it could be that they have
Speaker 1: a touch of the devil, as say, it was a
Speaker 1: pact with the devil. Right. Um. We look at at
Speaker 1: the left and the right in religious terms sometimes, and
Speaker 1: this is because if you look at text, you'll see
Speaker 1: that Jesus ascends to heaven on the right hand of God.
Speaker 1: You have a virginal reference of descending into hell on
Speaker 1: the left, and so you also have um. You have
Speaker 1: also have it ingrained in language like an Italian, the
Speaker 1: word for left is sinistra, which means sinister. So these
Speaker 1: things are already at playing here for the giving us
Speaker 1: this idea of how to proceed with lefties. And we
Speaker 1: just did an episode on symbols and how that is
Speaker 1: silently guiding us in the way that we perceived the
Speaker 1: world around us. Yeah. In the English language, right means
Speaker 1: both correct and right side. In our politics, left tends
Speaker 1: to denote the more radical side, um, the more left
Speaker 1: field right field versus right field. And and then you
Speaker 1: have things like left handed compliments where it's a compliment,
Speaker 1: but it's it's like a vile compliment that is meant
Speaker 1: to to drive home some sort of an insult. And then,
Speaker 1: of course, in various cultures, is also the idea that
Speaker 1: the left hand is the wiping hand for the for
Speaker 1: the pooh, and therefore to shake with the left hand
Speaker 1: is is frowned upon, or to do anything with the
Speaker 1: left hand. Okay, but what if what if the population
Speaker 1: all of a sudden we're lefties, Well we'd have a
Speaker 1: lot of stuff to change, right, I mean all the desks,
Speaker 1: which because suddenly the lefties there, this would be their
Speaker 1: dream scenario. Suddenly they're in charge, they would probably wipe
Speaker 1: the rest of us out. It's true, Um, And I'm
Speaker 1: just gonna predicate this on a study. It's a two
Speaker 1: thousand eleven study published in Psychological Science by Daniel Kasanto.
Speaker 1: And the idea is that you reverse the symbols of
Speaker 1: and bad right and left. It's like, yes, it is
Speaker 1: some some who have them and some who don't write
Speaker 1: and uh, what they are doing is they're saying unconsciously,
Speaker 1: right handers associate good with the right side of space
Speaker 1: and bad with the left. Now, of course, people who
Speaker 1: are left handed do not have the same association. They
Speaker 1: think the left hand and the left spaces are perfectly fine.
Speaker 1: This is what they found out when they messed with
Speaker 1: hand dominance. And what they wanted to do first, though,
Speaker 1: is they wanted to look at language and this idea
Speaker 1: of positive things being associated with the right side. And
Speaker 1: so to test this, they were asked, um, you know,
Speaker 1: right hand participants were asked which of two products to buy,
Speaker 1: which of two job applicants to hire, or which of
Speaker 1: two alien creatures looks more intelligent? Um. Right handers tended
Speaker 1: to choose the product, person, or creature they saw on
Speaker 1: their right, and most left handers, most of them chose
Speaker 1: the one on their left. Isn't that amazing that just
Speaker 1: in this spacial confige duration you can put person to
Speaker 1: a on the right, person be on the left, and
Speaker 1: if you're right handed, you're you're more apt to hire
Speaker 1: that person or to think that this person or creature,
Speaker 1: alien creature, is more intelligent than one on the left.
Speaker 1: And yet not to complicate via scenario that every time
Speaker 1: we look in the mirror and we consider the person
Speaker 1: most central to our view of the world, we're looking
Speaker 1: at a we're looking at a reflection, we're looking at
Speaker 1: a reversal. Um. But I think you're onto something. You're
Speaker 1: about the correcting of right and left in terms of
Speaker 1: their moral qualities, and about this this glove. Yeah, well
Speaker 1: this glove. The researchers put this on the right handers
Speaker 1: and the left handers, um, and they performed a motor
Speaker 1: fluency task while wearing this really bulky glove, and it
Speaker 1: turned these right handers in temporarily into left handers. And
Speaker 1: about only twelve minutes of this lopsided motor experience, the
Speaker 1: right glove participants judgments on an unrelated task showed a
Speaker 1: good it is left bias like natural left handers do.
Speaker 1: So it shows that you can just change up the
Speaker 1: scenario and actually have the bodily experience change your psychological experience. Yeah.
Speaker 1: So it's essentially Sylvester Monkey mcmonkey McBean's uh star on
Speaker 1: or star off machine this glove actor SEUs Yeah, and
Speaker 1: gazing into the future and considering this possibility of of
Speaker 1: suddenly they're being lefties. I can imagine them rounding up
Speaker 1: all the rights and making us wear those gloves so
Speaker 1: that they can change the way that we view the world.
Speaker 1: That might not be a bad thing, right, because did
Speaker 1: you hear that all the time? Like you should change
Speaker 1: the hand that you brush your teeth with because it's
Speaker 1: good for the brains, good for the brain. Right, So
Speaker 1: what if we decided all to do this? Is it possible?
Speaker 1: What would happen if we changed our handedness? I think that,
Speaker 1: I mean, it's worth worth drying. I want to do
Speaker 1: more of it because I was trying to think on
Speaker 1: the right end this morning. I was thinking, what do
Speaker 1: I do with my left hand? Um, I if I
Speaker 1: if my right hand is occupied, then I may use
Speaker 1: my left hand to drink water or whatever or if
Speaker 1: I'm on the train, I may read with my left
Speaker 1: hand while I'm holding onto the bar with my right.
Speaker 1: But for the most part of THO like, I don't
Speaker 1: do enough with it outside of the manipulation of various
Speaker 1: computer gadgets well. And as a result, actually your your
Speaker 1: nerves are less developed. And that's that side of your hand,
Speaker 1: by the way, um, because it takes a while if
Speaker 1: you're going to switch hands to try to build up
Speaker 1: his connections. It makes sense, right, because it's more of
Speaker 1: a pathway that's being used. And people who have sustained
Speaker 1: injuries now this and they're not able to use their
Speaker 1: left hand. Um. Actually, according to poor act that she's
Speaker 1: the professor of psychology that I had talked about before,
Speaker 1: one student that she studied who had been in an
Speaker 1: accident that permanently injured his dominant hand was able to
Speaker 1: eat with a four and other basic activities work just fine,
Speaker 1: but when it came to um cursive writing versus printing,
Speaker 1: he had a lot of trouble. I mean, printing was fine,
Speaker 1: but it turns out that when he was trying to
Speaker 1: write in cursive it was a bit of a nightmare.
Speaker 1: And that's because these two actions come from different regions
Speaker 1: of the same part of the brain, and there's a
Speaker 1: strip across the parietal lobe here. And handwriting is a
Speaker 1: fine motor skill, while printing is not. So not everything
Speaker 1: can be sort of perfect, even if you are building
Speaker 1: up those neural connections in your non dominant hand. Well,
Speaker 1: I was always a nightmare when I was trying to
Speaker 1: do cursive weaven with my dominant hands. So you know,
Speaker 1: I was writing a note to my daughter's teacher. For
Speaker 1: some reason I did in cursive. I guess I was
Speaker 1: trying to be fancy, and it was very hard because
Speaker 1: you know, in this day and age, it's very seldom
Speaker 1: that I actually write print anymore, let alone use cursive handwriting.
Speaker 1: Kind of hurt my brain a bit, all right, So
Speaker 1: I want to give you one more extreme example of
Speaker 1: becoming a lefty, and um, this can be found. Actually,
Speaker 1: the evidence of this can be found at the medieval
Speaker 1: Fernie Hurst Castle in Scotland. Uh So, just consider this
Speaker 1: fact that historically in castle's staircases are built so that
Speaker 1: the defenders at the top have their sword free to
Speaker 1: swing at opponents, while invaders have their swing impeded by
Speaker 1: the wall, so they're thinking about this when they're building
Speaker 1: the castle, like, how what's the advantage when I'm using
Speaker 1: my sword at the top and I'm trying to defend.
Speaker 1: According to Sally Lincoln Auger, she's a perceptual scientists at
Speaker 1: the University of Virginia, the Warrior clan care at this
Speaker 1: castle trained to use their weapons in their left hand,
Speaker 1: and even fitted their castle with a staircase that's tricked
Speaker 1: out just so that it could allow their left hands
Speaker 1: to wield a sword at invaders. And the ancestors of
Speaker 1: the clancare are all right dominant. So the idea here
Speaker 1: is that they weren't all, you know, miraculously lefties. They
Speaker 1: just knew that there was a lefty battle advantage, and
Speaker 1: so they actually train themselves to take advantage of that
Speaker 1: that advantage. Yeah, I thought that was pretty impressive. That
Speaker 1: is all right, Well they you have it, um a
Speaker 1: little insight into the world of lefties for you right
