WEBVTT - How Motion Sickness Works 0:00:01.320 --> 0:00:04.480 Welcome to you stuff you should know from house Stuff 0:00:04.480 --> 0:00:13.120 Works dot com. Hey, and welcome to the podcast. I'm 0:00:13.240 --> 0:00:17.880 Joshua Clark. There's Charles W. Chuck Bryant, and Jerry's over there. 0:00:18.920 --> 0:00:26.319 I'm speaking in a monotone kind of Hey, dude, Hey, 0:00:27.280 --> 0:00:32.479 how's it going. It's going well. I'm not motionsick, so 0:00:32.600 --> 0:00:36.800 things are fine. Do you get motion sick sometimes? I mean, 0:00:36.840 --> 0:00:39.320 if the conditions are right. I was really surprised to 0:00:39.360 --> 0:00:44.320 find that not everybody gets motion sick. What are your conditions? Um, 0:00:44.479 --> 0:00:48.559 poor ventilation and like lots of movement, um, backseat of 0:00:48.560 --> 0:00:53.840 a car. Okay, uh, but anytime I read in a car, 0:00:54.560 --> 0:00:58.600 even like glancing at my phone on a map. Really, 0:00:59.720 --> 0:01:03.440 if I have to read anything, it gets me very quick. 0:01:03.680 --> 0:01:05.839 So I've just learned that, like, I can't do it. Yeah, 0:01:05.920 --> 0:01:09.039 I cannot do it. So I don't I get it 0:01:09.080 --> 0:01:11.920 a little bit too. I used to get it more, 0:01:12.040 --> 0:01:15.360 I think when I was younger. Supposedly it's normal. Supposedly 0:01:15.440 --> 0:01:18.000 it is. But I remember a very specific story that 0:01:18.040 --> 0:01:21.160 my brother still laughs at. And by the way, boy, 0:01:21.200 --> 0:01:24.200 I'm glad I said that I owe my brother, my 0:01:24.280 --> 0:01:27.840 big brother, a big apology because I saw him over 0:01:27.840 --> 0:01:30.760 the weekend and he said, oh, by the way, I 0:01:30.800 --> 0:01:32.399 was just done an old episode and he said, you've 0:01:32.400 --> 0:01:35.840 never been a groom's a best man. I was the 0:01:35.880 --> 0:01:40.080 best man at my brother's wedding. Man. I felt like 0:01:40.120 --> 0:01:43.720 a jerk, man, Scott, I'm sorry, I know. And what 0:01:43.840 --> 0:01:46.280 happened was when I said I hadn't, I just like 0:01:46.840 --> 0:01:49.640 quickly scanned through my friends that have gotten married, and 0:01:49.680 --> 0:01:51.840 I didn't think about my brother and I was his 0:01:51.880 --> 0:01:57.480 best man. A jerk. Well, it's it's rectified now. Well 0:01:57.520 --> 0:01:58.840 I told him. I was like, you're gonna get a 0:01:58.840 --> 0:02:02.320 public apology. So there it is. That's pretty public. Yeah, 0:02:02.440 --> 0:02:06.040 it gets. You could have also started a scores based 0:02:06.120 --> 0:02:11.440 website if you wanted, but it's really easy that. Um So, anyway, 0:02:11.440 --> 0:02:15.640 this is old story. When we went to Disney, uh geez, 0:02:15.639 --> 0:02:20.080 which is the one where Body Wars is at. You 0:02:20.080 --> 0:02:22.320 should have asked Holly from stuff you missed in history, 0:02:22.520 --> 0:02:24.640 she would know if she probably senses that someone's talking 0:02:24.639 --> 0:02:29.480 about Disney right now. Body Wars either was or still is. 0:02:29.520 --> 0:02:31.120 I don't know if it's still there. One of those 0:02:31.520 --> 0:02:33.760 rides that you sit in a you know, it's one 0:02:33.760 --> 0:02:36.800 of those first sort of virtual things where they show 0:02:36.840 --> 0:02:38.840 you a movie and then they moved the car, like 0:02:38.880 --> 0:02:41.160 The Amazing Voyage or something, wasn't it. Yeah, you went 0:02:41.200 --> 0:02:43.919 inside a human body and we're traveling around. I want 0:02:43.919 --> 0:02:47.240 to say disney World, but I can't remember. Um so 0:02:47.280 --> 0:02:50.040 I went in that, And I mean, wait, I'm getting 0:02:50.040 --> 0:02:51.840 you grew up in Atlanta. I'm guessing you went to 0:02:51.919 --> 0:02:54.040 disney World. Well, it definitely was at Disneyland, but I 0:02:54.040 --> 0:02:57.720 don't know if he was Epcot, Universal Studio Guys, or 0:02:57.760 --> 0:02:59.680 Disney World. It was in Orlando. So from what I 0:02:59.720 --> 0:03:02.280 under stand, we have a buddy who works for Disney 0:03:02.360 --> 0:03:04.400 and he set me straight on this before, and I 0:03:04.440 --> 0:03:09.200 think I've got it. So disney World is all of those. 0:03:10.080 --> 0:03:13.320 The Magic Kingdom is what you're specifying. So disney World 0:03:13.320 --> 0:03:16.840 includes Epcott and Universal Studios. If I'm not mistaken, I 0:03:16.960 --> 0:03:19.640 really hope I'm not missing. The Magic Kingdom is specifically 0:03:21.280 --> 0:03:24.200 with the Castle. Right. If I did get that wrong, Brandon, 0:03:24.280 --> 0:03:27.600 I apologize. It's one with the castle. All the weird 0:03:27.639 --> 0:03:34.320 adults that think their children like, uh so, body wars. Anyway, 0:03:34.360 --> 0:03:36.160 you're traveling through the body, and I remember at one 0:03:36.160 --> 0:03:38.480 point I was like, man, it's getting hot in here, 0:03:38.920 --> 0:03:40.880 and Scott's like, this is great. I was like, I'm 0:03:40.880 --> 0:03:42.680 not feeling so good man. It's like, do they have 0:03:42.760 --> 0:03:44.480 the heat going. It's like, what are you talking about? 0:03:44.520 --> 0:03:47.680 It feels great? And I got I didn't vomit, but 0:03:47.720 --> 0:03:50.760 I got really sick and made it through the ride 0:03:50.760 --> 0:03:53.119 and left. And he still teases me to this day. 0:03:53.200 --> 0:03:56.320 He was like, it was temperature air controlled, and you 0:03:56.360 --> 0:03:58.000 thought it was like ninety degrees and they were like 0:03:58.040 --> 0:04:00.800 pumping in heat. It's funny, like it got to you 0:04:00.840 --> 0:04:04.240 like that, like your own body cold sweats the who while, yeah, 0:04:04.280 --> 0:04:08.200 that's bad, but generally you you actually did puke, No, no, no, 0:04:08.240 --> 0:04:12.040 I did not, you didn't. But generally I don't like 0:04:12.120 --> 0:04:14.600 it takes a certain thing, like a really hardcore roller 0:04:14.640 --> 0:04:18.800 coaster going in fast, fast circles, but I don't get 0:04:18.839 --> 0:04:21.560 sick complaints or the one cruise I went on, it 0:04:21.600 --> 0:04:26.279 didn't get sick. Yeah, you know, I've gotten. I've gotten 0:04:26.360 --> 0:04:31.440 sick before, like on vacation. But and I'm planes, it's 0:04:31.520 --> 0:04:35.080 usually fairly fleeting. It's when I introduced reading that it's 0:04:35.120 --> 0:04:37.880 like you're in big trouble for a long time. You 0:04:37.880 --> 0:04:42.479 can read on a plane though I can't. Yeah, yeah, yeah, 0:04:42.640 --> 0:04:44.159 now I think about it's reading in a car. I 0:04:44.200 --> 0:04:46.360 just gotta stay away from that. But usually it does 0:04:46.440 --> 0:04:49.000 come about with like poor ventilation that kind of thing, 0:04:49.520 --> 0:04:51.560 um yeah, which is another trigger, it's a big one, 0:04:51.680 --> 0:04:54.400 or like a rough odor or something like that. I'm 0:04:54.440 --> 0:04:57.159 sure all those things don't help. The thing is for 0:04:57.160 --> 0:04:59.960 for as much as like we kind of commonly understand 0:05:00.040 --> 0:05:04.920 and motion sickness, science really doesn't have a full explanation 0:05:05.000 --> 0:05:08.760 for it. I'm picturing little Josh because riding backwards is 0:05:08.760 --> 0:05:11.120 bad and like a rumble seat in a station wagon, 0:05:11.680 --> 0:05:14.120 in a in a super u brat with like your 0:05:14.200 --> 0:05:17.880 dad has like salami socks on or something that stink 0:05:18.440 --> 0:05:20.640 what like the windows are rolled up. I don't know, 0:05:20.640 --> 0:05:24.320 it just anything. It's something gross salamie socks, like socks 0:05:24.360 --> 0:05:29.920 made of salami, Like, wouldn't that smelled gross? He's wearing 0:05:29.920 --> 0:05:32.120 the skin of another person. Well, now I was thinking 0:05:32.960 --> 0:05:36.080 smelled like old salami, but made of salamis even better, right. 0:05:36.560 --> 0:05:39.200 I think I'm just picturing you back there, like reading 0:05:39.200 --> 0:05:42.320 your Mad magazine feeling bad. Yeah, yeah, no, I do 0:05:42.400 --> 0:05:44.960 remember being a kid and figuring out I can't read 0:05:44.960 --> 0:05:47.440 in cars. There was a period where I could, which 0:05:47.480 --> 0:05:50.520 is kind of surprising because when you're younger, you're more 0:05:50.520 --> 0:05:54.320 susceptible to motion sickness. But I could read in the 0:05:54.440 --> 0:05:57.520 car while I was younger, and then probably around the 0:05:57.560 --> 0:05:59.919 time of puberty, I was like, I can't do this anymore. 0:06:00.080 --> 0:06:05.320 You went opposite weird. Yeah, well maybe you developed your hips, right, 0:06:06.120 --> 0:06:08.320 because that's a tease. We'll just leave that out there, 0:06:08.800 --> 0:06:15.800 all right. So people supposedly are susceptible to motion sickness. Uh, 0:06:15.839 --> 0:06:19.160 and it can happen on planes, it can happen. It's weird. 0:06:19.240 --> 0:06:22.480 This one University of Maryland side I went to said, uh, 0:06:23.120 --> 0:06:25.400 the following are the most common risk factors riding in 0:06:25.400 --> 0:06:31.479 a car, boat, airplane, or space shuttle. Really, yeah, nerds, 0:06:31.720 --> 0:06:34.479 Just like they didn't even put the amusement park ride. 0:06:35.000 --> 0:06:37.200 They just went straight to space shuttle. You know, one 0:06:37.240 --> 0:06:39.719 that I hadn't seen before. But apparently as the thing is, 0:06:39.800 --> 0:06:42.719 I'm looking through a microscope, Yeah I hadn't. That makes 0:06:42.720 --> 0:06:44.480 a little bit of sense though, Yeah, because the slide 0:06:44.480 --> 0:06:46.520 can move in. Your eyes are seeing movement, but you're 0:06:46.520 --> 0:06:50.359 not moving, and yeah, I'll get to you. Uh. Like 0:06:50.400 --> 0:06:55.040 another nerdy motion sickness space shuttles and microscope. Uh So, 0:06:55.080 --> 0:06:57.440 like you said, age between two and twelve, you're more 0:06:57.560 --> 0:07:00.560 likely uh, and then you're also more likely to grow 0:07:00.600 --> 0:07:04.160 out of it after puberty. And one of the reasons 0:07:04.200 --> 0:07:09.039 that women are more motion sickness than men or get 0:07:09.080 --> 0:07:11.760 motion sickness more than men is because one of the 0:07:11.760 --> 0:07:15.240 theories is that after puberty they developed more in the hips. 0:07:15.480 --> 0:07:20.000 Men develop more in the chest, and I guess that 0:07:20.040 --> 0:07:22.760 makes a difference. They didn't really explain why they did that. Well, 0:07:22.760 --> 0:07:25.600 it all has to do with sway theory, which Will's right, 0:07:25.640 --> 0:07:28.840 sway theory. Yeah, but it is true that, like, women 0:07:28.920 --> 0:07:32.520 are more susceptible just on average, to motion sickness than 0:07:32.560 --> 0:07:38.040 men are. Yeah, studies apparently also Asian women, well Asian 0:07:38.080 --> 0:07:41.840 period because Pinn State did a study and they put 0:07:41.960 --> 0:07:45.600 people in situations that make emotion sick or not. Did 0:07:45.680 --> 0:07:49.800 you look into those Oh is it like a tilted world, dude? 0:07:50.040 --> 0:07:52.800 Like if you went in for just a clinical study, 0:07:52.800 --> 0:07:54.720 like I'm gonna make some scratch or maybe they'll give 0:07:54.720 --> 0:07:56.800 me a cool drug or something, and it turns out 0:07:56.840 --> 0:07:59.440 to be a motion sickness study, you should leave. No, 0:07:59.560 --> 0:08:02.120 I totally was. So there's this thing called a um 0:08:02.600 --> 0:08:05.600 opt to kinetic drum, I believe is what it's called. 0:08:05.760 --> 0:08:08.120 Oh I did see that. Yeah, I have to connectic. 0:08:08.480 --> 0:08:12.200 It's it's like um a drum, like a big drum 0:08:12.240 --> 0:08:15.080 that you sit inside of, and it's got a vertical 0:08:15.160 --> 0:08:17.920 black and white painted stretched and it spins around you 0:08:18.640 --> 0:08:21.920 and the motion, the movement is really emphasized and like 0:08:22.000 --> 0:08:25.040 it's designed to make anybody motion sick and that's how 0:08:25.080 --> 0:08:28.280 they induce motion sickness. And I saw another one UM 0:08:28.320 --> 0:08:30.440 where they use a chair that just kind of moves 0:08:30.440 --> 0:08:33.120 you around, whether you like it or not, and it 0:08:33.160 --> 0:08:36.600 induces motion sickness. Like, what a terrible thing to have 0:08:36.760 --> 0:08:39.360 happened to you. Man. There was a ride at six 0:08:39.360 --> 0:08:41.559 Flags over Georgia growing up that they got rid of 0:08:41.600 --> 0:08:45.600 because someone got hurt, supposedly where it's this barrel that 0:08:45.640 --> 0:08:48.600 you all get in. You stand it, it's like kind 0:08:48.600 --> 0:08:51.000 of below ground. You stand against the wall. Love those 0:08:51.080 --> 0:08:53.600 and it's spins so fast. Then they dropped the floor 0:08:53.640 --> 0:08:56.240 beneath you and then some trifical force holds you against 0:08:56.240 --> 0:08:58.480 the wall. It's like the spin cycle in the washing machine. 0:08:58.520 --> 0:08:59.920 You mean, I were just talking about that. The other 0:09:00.040 --> 0:09:03.240 thing was awful. That was my favorite of all time. Really, 0:09:04.280 --> 0:09:06.600 I just thought it was so cool. Well, the old 0:09:06.600 --> 0:09:08.960 story was that someone's leg got trapped when the floor 0:09:09.000 --> 0:09:10.839 came back up. But I remember here now that I 0:09:10.880 --> 0:09:12.960 look back, because I'm sure that was an old live stale. 0:09:13.080 --> 0:09:15.720 Although I was on Snoops the other day and I 0:09:15.800 --> 0:09:18.839 was reading an early article and they were talking about, um, 0:09:18.880 --> 0:09:21.200 you know, the urban legend about some girl who got 0:09:21.200 --> 0:09:23.960 scalped because her hair got caught in an amusement park 0:09:24.040 --> 0:09:27.720 ride or something. It actually happened, really, Yeah, the girl's 0:09:27.720 --> 0:09:30.160 ponytail got caught in there. It just got pulled right 0:09:30.200 --> 0:09:33.840 off of her head. I know, but it actually did happen. 0:09:33.960 --> 0:09:36.720 So it's possible someone's leg got got sucked into the 0:09:36.720 --> 0:09:39.600 tiltal world. Well, but then what happens is it happened 0:09:39.600 --> 0:09:46.000 at every amusement park, right, It happened to my cousin's friend, right, Alright. 0:09:46.000 --> 0:09:48.400 So the Penn State study, uh, they put people in 0:09:48.440 --> 0:09:53.520 these torture machines, and interestingly, they did confirm eight of 0:09:54.400 --> 0:09:58.640 Asian people got sick when it was less than fifty 0:09:58.679 --> 0:10:02.920 percent for Caucasian and non Caucasian, which is really it's 0:10:03.040 --> 0:10:06.320 very crazy. Um, but it kind of underscores a growing 0:10:06.360 --> 0:10:11.320 awareness among motion sickness researchers a K that the evil 0:10:11.360 --> 0:10:16.040 ones um that genetics play a big role in susceptibility 0:10:16.120 --> 0:10:19.160 to motion sickness. Well, yeah, because there were another couple 0:10:19.200 --> 0:10:23.520 of findings that lend to that. UM. Twins. They study 0:10:23.600 --> 0:10:28.080 two hundred sets of identical twins, and one percent of 0:10:28.160 --> 0:10:32.880 the identical twins were both affected. Um. Yeah, and some 0:10:32.920 --> 0:10:35.280 of that, you know, they can't prove that it's genetics 0:10:35.320 --> 0:10:39.320 because it also could be the uh just where they 0:10:39.320 --> 0:10:40.880 were raised and how were they were raised. What's it 0:10:41.000 --> 0:10:48.199 called uh nurture environment environment environmental um. And if parents 0:10:48.240 --> 0:10:52.000 are both susceptible to motion sickness, they found that their 0:10:52.080 --> 0:10:55.280 children are five times more likely. So it's sort of 0:10:55.280 --> 0:10:59.439 points to genetics. But then other things point away from genetics, 0:10:59.520 --> 0:11:03.920 like why why would you know two people in the 0:11:04.000 --> 0:11:09.240 same family in the same conditions not get sick? Or 0:11:09.280 --> 0:11:11.880 why did why why did two people period not get 0:11:11.920 --> 0:11:15.800 sick under the same conditions. Yeah, Like, I guess what 0:11:15.840 --> 0:11:20.160 I'm saying, salami socks smell same backwards facing seat. Yeah, 0:11:20.280 --> 0:11:22.520 I guess what I'm saying is they haven't figured it out, No, 0:11:22.640 --> 0:11:25.200 they haven't. But if we do figure out that it's genetic, 0:11:25.240 --> 0:11:28.400 thanks to the magic of the Crisper Casts nine gene 0:11:28.600 --> 0:11:31.720 editing process to be able to knock that right out 0:11:32.200 --> 0:11:35.800 for you, what else is pregnant? Yeah, pregnant women are 0:11:35.840 --> 0:11:39.800 more susceptible to it. Um, women who are menstruating, I 0:11:39.840 --> 0:11:44.680 think also are, and people who get migraines are more susceptible. 0:11:44.720 --> 0:11:47.520 And then people who sleep poorly are more susceptible to 0:11:47.960 --> 0:11:51.679 um uh. Motion sickness. Yeah, it says if you're prone 0:11:51.679 --> 0:11:54.040 to nausea or vomiting, but I don't know if that's like, 0:11:54.360 --> 0:11:57.439 that's sort of a chicken or the egg thing. Well, 0:11:57.760 --> 0:12:00.080 we're gonna get into again. We said science as to 0:12:00.120 --> 0:12:03.080 understand exactly what's going on here. But there's some good theories. 0:12:03.520 --> 0:12:32.400 We're gonna talk about them right after, so chuck, Yeah, 0:12:32.920 --> 0:12:36.559 let's talk about some theories for motion sickness because it's 0:12:36.600 --> 0:12:39.680 kind of two Yeah. I saw I think it was 0:12:39.720 --> 0:12:44.680 this Atlantic article you sent. It's not so much um, 0:12:44.760 --> 0:12:48.960 it's not so much science. It's a debate over you know, 0:12:49.000 --> 0:12:51.800 the likelier explanation, but they actually kind of fit together. 0:12:52.080 --> 0:12:54.760 I think so, but if you ask the people, apparently 0:12:54.960 --> 0:12:58.360 the author in the Atlantic, Uh, it's called the Mysterious 0:12:58.360 --> 0:13:01.719 Science Emotion Sickness. He's sort of pokes fun a little bit. 0:13:02.040 --> 0:13:03.640 He's like, to me, they sound sort of the same. 0:13:03.679 --> 0:13:05.920 But don't tell that to those people who believe one 0:13:06.000 --> 0:13:07.640 or the other, because they're like, no, they're nothing like 0:13:07.720 --> 0:13:12.360 each other. She Julie beck I was that, who wasn't nice? Job, 0:13:12.440 --> 0:13:15.960 Julie good article. Um, pat on the back for you, 0:13:16.520 --> 0:13:20.000 cold star. So, uh, here's the first one is and 0:13:20.040 --> 0:13:24.760 this one. They both make a lot of sense to me. Um. Basically, 0:13:24.800 --> 0:13:28.160 there's a dissonance between the parts of your body that 0:13:28.240 --> 0:13:31.199 sense motion. Right, that's the easiest way to say it. 0:13:31.200 --> 0:13:36.000 It's called the sensory conflict theory. To get dryballs. Yeah, 0:13:36.360 --> 0:13:39.280 that it senses motion. It's it's weird if you think 0:13:39.320 --> 0:13:40.920 about your eyes doing that, but that's one of the 0:13:41.000 --> 0:13:44.920 roles that they play in motion. You also have the 0:13:45.000 --> 0:13:48.800 vestibular system, which is centered around your inner ear, and 0:13:48.920 --> 0:13:54.440 that definitely senses motion, movement, acceleration, gravity. Uh. And then 0:13:54.840 --> 0:13:57.080 you have all the sensors, the sensors and like your 0:13:57.160 --> 0:13:59.360 muscles and joints and stuff, right, Yeah, I didn't really 0:13:59.400 --> 0:14:02.600 think about that is being one, but for sure, like 0:14:02.679 --> 0:14:05.560 your body actually feels it. Yeah, well, think about it, 0:14:05.600 --> 0:14:09.840 like if you if you feel yourself kind of moving backward, 0:14:10.240 --> 0:14:12.840 you're definitely sensing it through your inner ear, but you 0:14:12.840 --> 0:14:14.720 can also feel it in your feet as well, and 0:14:14.760 --> 0:14:20.400 they're sending a a bulletin to your brain saying, lean forward, dummy, 0:14:20.600 --> 0:14:25.760 you're gonna fall back. What's your problem? Friend? So, this 0:14:25.800 --> 0:14:28.440 dissonance occurs when basically, like let's say you're sitting in 0:14:28.440 --> 0:14:32.560 a movie theater like an IMAX and it's a scene 0:14:32.560 --> 0:14:35.560 where you're you're flying with Superman or something like. You're 0:14:35.600 --> 0:14:39.680 seeing this with your eyeballs like a first person perspective 0:14:39.720 --> 0:14:43.160 shot of flight, but you're sitting in your seat, so 0:14:43.200 --> 0:14:45.800 your eyes are saying you're flying and your butts going 0:14:45.920 --> 0:14:49.360 you're sitting here and your brains like a witch. Yeah, 0:14:49.520 --> 0:14:54.560 pretty much witchcraft. Uh. So it creates this, This creates 0:14:54.560 --> 0:14:58.280 motion sickness. That's when the uh, nausea might kick in, dizziness, uh, 0:14:58.360 --> 0:15:02.000 those cold sweats, salivation. I like how the the author 0:15:02.040 --> 0:15:05.600 of the house Stuff Works article pointed out she specifically 0:15:05.720 --> 0:15:11.400 mentioned Avatar. Yeah, who is the dude? Um? The the 0:15:11.440 --> 0:15:13.280 guy who was like the friend on the Flight of 0:15:13.320 --> 0:15:18.280 the Concords Mary. No, the other dude, the guy who 0:15:18.280 --> 0:15:21.040 worked in the pond. Yeah, yeah, oh man, what is 0:15:21.040 --> 0:15:24.200 his name? It's not Range Parker, Arrange Parker, Yes, it was. 0:15:24.240 --> 0:15:26.320 I always want to call him Boslerman. I know it's 0:15:26.440 --> 0:15:29.640 definitely not the same dude Parker. You mean. I went 0:15:29.680 --> 0:15:31.400 to go see him. He did some stand up, right, 0:15:31.400 --> 0:15:33.120 and he was talking about Avatar, and he said, when 0:15:33.120 --> 0:15:35.320 it first came up, people like, oh, Avatar, have you 0:15:35.360 --> 0:15:38.160 seen Avatar? Yea great And then like everything you heard 0:15:38.240 --> 0:15:40.600 was have you seen Avatar? You gotta see Avatar, you said, 0:15:40.640 --> 0:15:42.720 like after a couple of weeks, you'd just be walking 0:15:42.760 --> 0:15:45.040 down the sidewalk and people would pull up alongside you 0:15:45.080 --> 0:15:47.400 in your car and roll down the window and go Avatar. 0:15:48.920 --> 0:15:51.360 And this is I think a great example of that. Well, 0:15:51.400 --> 0:15:54.240 it's interesting. I posted an article on Facebook not too 0:15:54.280 --> 0:15:56.280 long ago on the Stuff you Should Know page about 0:15:56.800 --> 0:16:00.520 this person wrote an article about Avatar and the argument 0:16:00.600 --> 0:16:03.600 was that it for such a huge movie, it had 0:16:03.640 --> 0:16:08.120 like zero cultural impact, Like it was big at the time, 0:16:08.560 --> 0:16:11.160 but does anyone care now, Like it's not like the 0:16:11.200 --> 0:16:13.920 Star Wars World or Star Treker, all these things, and 0:16:13.960 --> 0:16:17.000 I totally agreed. I saw Avatar once and I was like, 0:16:17.360 --> 0:16:20.480 I'm done with it. Typical James Cameron schlock. I've seen 0:16:20.480 --> 0:16:24.800 it zero times. No, that sucks, But dude, there are 0:16:24.880 --> 0:16:27.920 Avatar people though, that piled on and we're like, what's 0:16:28.000 --> 0:16:31.080 god no idea what he's talking about? It's totally relevant. Oh, 0:16:31.120 --> 0:16:33.520 I'm sure they're gonna be all over Facebook page after 0:16:33.560 --> 0:16:37.520 this episode comes out. Hey, Chuck forever. Now, I like 0:16:37.600 --> 0:16:39.920 some of James Cameron stuff, but if he wrote the script, 0:16:40.640 --> 0:16:44.040 then it's I'm not gonna like it. No, I know 0:16:44.080 --> 0:16:47.920 what you mean. I think he's a hack writer. Yeah. 0:16:48.040 --> 0:16:51.440 Did I just say that two hundreds of thousands of people? Yeah, 0:16:51.520 --> 0:16:53.680 And I'm sure James Cameron cares what you think. He's 0:16:53.680 --> 0:16:56.880 at the bottom of the Marianna Trench right now. He's not. 0:16:58.040 --> 0:17:02.280 He's picking out my future burial site. So um, Chuck, 0:17:02.480 --> 0:17:07.040 we're talking about the century conflict theory, right, that's one 0:17:07.080 --> 0:17:10.160 big explanation, and it definitely kind of makes sense. Right. 0:17:10.280 --> 0:17:13.480 Your your brain just basically gets overloaded and it's like, oh, 0:17:13.600 --> 0:17:16.320 I need to sit down. I've got the vapors, right, 0:17:17.119 --> 0:17:20.080 I'm doing a lot of bad impressions in this episode 0:17:20.160 --> 0:17:24.760 was supposed to be uh, somebody fainting in the late 0:17:24.800 --> 0:17:26.919 nineteenth century. Oh, no, it's great. So it was your 0:17:27.000 --> 0:17:29.359 arch Parker fop. That's what it was. It was a 0:17:29.400 --> 0:17:36.159 fop the dandy popping. There's another competing idea, and that is, UM, 0:17:36.200 --> 0:17:41.680 we kind of talked about. UM. It's called sway theory. Yeah. 0:17:41.800 --> 0:17:47.200 And there's a dude, h Thomas uh staff or staff Regin. 0:17:47.640 --> 0:17:55.000 I'm going with the gin s University of University of Minnesota, 0:17:55.040 --> 0:17:59.600 Professor of Kinesiology and listen to this. He's the director 0:17:59.720 --> 0:18:05.679 of it Affordance Perception Action Laboratory NERD. He gets motion 0:18:05.720 --> 0:18:11.879 sickness looking through microscope. UM. So he proposes the sway 0:18:11.920 --> 0:18:15.560 theory UM, which basically has nothing to do with the 0:18:15.640 --> 0:18:18.439 vestibular system. He said. He says that I don't I 0:18:18.440 --> 0:18:21.159 don't necessarily agree with that, but okay, I agree that 0:18:21.200 --> 0:18:23.199 he thinks that. No, I know that he thinks that 0:18:23.320 --> 0:18:25.960 I don't agree with that his take on that. Agree. 0:18:25.960 --> 0:18:28.240 I think it's still tied together. But his theory is 0:18:28.359 --> 0:18:30.399 and this first part isn't theory. It's true is that 0:18:30.440 --> 0:18:34.600 everyone sways like unless you're one of those uh people 0:18:34.680 --> 0:18:38.000 that stand like motionless in the middle of New Orleans 0:18:38.720 --> 0:18:42.920 for money. M hmm, yeah, silver or something like that. Yeah, 0:18:42.920 --> 0:18:45.040 they're good, they're good at it. But if you're just 0:18:45.080 --> 0:18:47.840 a regular dope like you and I, when we stand there, 0:18:47.840 --> 0:18:50.200 we're gonna be moving in a little bit. Yeah, you 0:18:50.320 --> 0:18:52.960 mean swaying a little bit. It's weird, like if you 0:18:53.200 --> 0:18:56.360 stop and like really pay attention to it. Yeah, you 0:18:56.359 --> 0:18:58.919 you notice it, but you'll never notice it unless you 0:18:59.080 --> 0:19:02.640 are focused on that. Yeah, you're always moving a little bit. Yeah, swaying. 0:19:02.760 --> 0:19:06.000 If you're standing up, you're swaying for the most part. Yes. 0:19:06.080 --> 0:19:08.560 And the point he makes is if everyone truly relaxed 0:19:08.560 --> 0:19:11.320 every muscle in their body, they'd fall over. Right. So 0:19:11.359 --> 0:19:13.360 the whole point, the whole thing is swaying is it's 0:19:13.400 --> 0:19:16.879 the byproduct of us standing upright, which is not something 0:19:16.960 --> 0:19:20.720 we've been doing for all of the time we've been 0:19:20.760 --> 0:19:24.399 on earth, because we evolved from things that walked on 0:19:24.560 --> 0:19:27.760 four legs. Standing up is kind of new. Well, sure, 0:19:27.800 --> 0:19:31.280 and babies don't stand up, they have to, yeah, exactly. 0:19:31.640 --> 0:19:36.760 So um Stoffordgin's whole idea is that motion sickness comes 0:19:36.800 --> 0:19:42.360 about when you have um when you're exposed to movement 0:19:42.960 --> 0:19:48.840 that contradicts the natural um swaying that you've learned to 0:19:48.840 --> 0:19:51.919 do to stand upright right, and it undermines it, and 0:19:52.040 --> 0:19:55.359 your brain goes Which makes sense in a way because 0:19:55.400 --> 0:19:58.560 let's say you're on a boat and the boat's tilting 0:19:58.560 --> 0:20:01.760 to the left, and so what you're feet do, or 0:20:01.840 --> 0:20:04.960 you know, they account for that, and maybe you lean 0:20:05.040 --> 0:20:06.639 in on the inside of your foot and your toes 0:20:06.720 --> 0:20:10.440 flex so because you want to make yourself more upright again. 0:20:10.920 --> 0:20:13.120 And then the boat turns again in a direction you're 0:20:13.160 --> 0:20:16.480 not expecting. You're correcting for that first move, the second 0:20:16.480 --> 0:20:19.320 move happens, and your body doesn't know what to do. 0:20:19.560 --> 0:20:24.480 So here's the thing. The the sensory conflict one makes 0:20:24.480 --> 0:20:27.720 a little more sense to me than this one, because 0:20:28.000 --> 0:20:30.000 that sounds to me like if that if that were 0:20:30.040 --> 0:20:32.439 the case, if that's what's going on, and it clearly is. 0:20:32.520 --> 0:20:35.000 Like when it's when you get your sea legs or 0:20:35.000 --> 0:20:39.840 whatever um you you you were moving along, you're trying 0:20:39.840 --> 0:20:43.600 to stay standing under these weird conditions, why would that 0:20:43.640 --> 0:20:47.639 translate into something like dizziness or nausea or vomiting or 0:20:47.800 --> 0:20:51.080 cold sweats that doesn't make sense to me. Sensory conflict 0:20:51.119 --> 0:20:54.080 I can see translating into it. But even beyond that, 0:20:54.119 --> 0:20:55.880 a lot of people are like, no, that doesn't Still, 0:20:55.920 --> 0:20:58.040 it doesn't make sense why you would vomit. And this 0:20:58.160 --> 0:21:02.000 one guy named um Michael Easman seven came up with 0:21:02.040 --> 0:21:06.040 a pretty awesome explanation for why we should get nauseated 0:21:06.040 --> 0:21:08.520 when we get motion sick right. Well, yeah, should we 0:21:08.560 --> 0:21:35.280 take a break and talk about that? Oh all right, 0:21:35.560 --> 0:21:39.120 Josh Michael Treatman seven in the journal Science. What did 0:21:39.119 --> 0:21:43.760 he say? Oh? He said that we get nauseated from 0:21:43.840 --> 0:21:48.000 motion sickness because over there are some toxins out there 0:21:48.440 --> 0:21:51.880 that can mess with our vestibular system. Right, yes, So 0:21:52.280 --> 0:21:56.520 the body is tricked into thinking that it's possibly been 0:21:56.560 --> 0:22:00.720 exposed to some sort of toxin because the vestibular vestibular 0:22:00.720 --> 0:22:03.480 system is out of whack from motion sickness, So it 0:22:03.480 --> 0:22:07.760 gets nauseated and ultimately might vomit as a reflex to 0:22:07.800 --> 0:22:10.480 get rid of whatever toxin it thinks has been ingested. 0:22:11.240 --> 0:22:14.600 It's basically a case of mistaken identity. I think it 0:22:15.160 --> 0:22:18.320 explained it perfectly. It makes sense to me. I could 0:22:18.320 --> 0:22:21.720 see a little bit. I think what Um what staff 0:22:21.760 --> 0:22:25.160 Regin is saying is that you're you're used to regaining 0:22:25.200 --> 0:22:28.880 your balance. You spend your entire life learning this system, 0:22:28.920 --> 0:22:32.879 and that if it's thrown off, what he doesn't do 0:22:32.960 --> 0:22:35.280 is connect it. I believe, I believe you're right. He 0:22:35.320 --> 0:22:37.720 doesn't connect it in the end to like something that 0:22:37.760 --> 0:22:41.840 happens in your brain, right, the the why the physiological 0:22:41.880 --> 0:22:45.280 reaction agreed. Yeah, but he does have some pretty good 0:22:45.320 --> 0:22:49.560 evidence backing his idea of sway theory up though. Um, 0:22:49.600 --> 0:22:55.040 so again, women are more susceptible to um to motion 0:22:55.119 --> 0:22:57.560 sickness than men. Right, Yes, that's what they say. Well, 0:22:57.560 --> 0:23:01.879 he says, ah, Well, Sway theory explains that um, kids 0:23:01.920 --> 0:23:05.879 are equally susceptible to both genders are equally susceptible to 0:23:05.960 --> 0:23:10.520 motion sickness before puberty. Then after puberty, the bodies change 0:23:10.720 --> 0:23:13.840 and where um, women and men hold most of their 0:23:13.880 --> 0:23:17.960 weight is different. Right, Women hold it mostly around their hips. 0:23:18.119 --> 0:23:20.640 Men hold it more around their chest, and that means 0:23:20.680 --> 0:23:23.159 that the center of gravity is different, which means the 0:23:23.200 --> 0:23:26.879 amount that we sway is different. Right yeah, I think Uh? 0:23:28.440 --> 0:23:32.600 Who does he say sways? Women's way farther but slower, 0:23:32.640 --> 0:23:36.679 but slower Men's sway faster but within a tighter area. 0:23:37.560 --> 0:23:40.159 And and these are micro sways. Yeah, I mean I 0:23:40.160 --> 0:23:42.879 think that like most people move no more than like 0:23:42.920 --> 0:23:46.320 an inch to any given side. And even then you're 0:23:46.320 --> 0:23:48.879 like Barney on the Simpsons when he walked out for 0:23:48.960 --> 0:23:55.760 that like bachelor um auction. Uh. Then there's also landsickness, 0:23:56.440 --> 0:23:59.120
