#326 – David Rush

Sevan Matossian (00:02):

Hey, I’m more live.

Advertisement (00:06):

That’s a sound of a 360 degree barbell brush by hybrid athletics.

Sevan Matossian (00:12):

Good morning. Hey David.

David Rush (00:15):

Good morning.

Sevan Matossian (00:16):

Let me fix my earphones here. Ah, there you are. Thanks for coming on, man.

David Rush (00:23):

You bet looking forward to it today.

Sevan Matossian (00:25):

Holy cow, David Rush. If you have not been to the David Rush YouTube channel, you should go there now and you should go there with your kids. I’ve been having a blast with you, buddy. You are a man on a mission. Are you still on that mission?

David Rush (00:44):

Uh, you know, I, I haven’t given up yet. I’m still going after some more records.

Sevan Matossian (00:48):

Are you the, um, in, in one of the videos in 2021, I heard you say that you might be the third, most Guinness records in the book for an individual. Do you know where you rank amongst that? And did I hear that correctly?

David Rush (01:03):

I, I believe so. Yeah. Guinness doesn’t track this anymore. They don’t award a record for the most records, so it’s not to be self referential, but they, but they, I do have a way to look up how many records each person currently holds. And I’m currently number three on that list, uh, with currently held records. That means I’ve broken. ’em, they’ve been approved by business and nobody else has broken. It’s about 110,

Sevan Matossian (01:25):

Uh, uh, uh, but you’ve held as many as 200.

David Rush (01:30):

I’ve broken over 200 records. Some of those I’ve rebroke or some of I’ve lost.

Sevan Matossian (01:35):

Okay. Okay. Interesting. Interesting. Hey, uh, I, I, I know you’re from, from your site, uh, you were a gentleman, you seem to care a lot about kids. So I apologize for language, but that seems like complete horse that they don’t track the person who has the most records that’s that’s insanity to me.

David Rush (01:53):

Well, they know it. Um, but they don’t award a Guinness world records for the most Guinness world records. So as not to be self referential,

Sevan Matossian (02:02):

As a, sorry, and now we’re about to go down a rabbit hole as opposed to, and why would be, I was that they didn’t wanna do it because they didn’t, they thought maybe it would be dangerous to encourage that, but, but what do they mean? Self-referential like, who cares?

David Rush (02:15):

So referencing themselves.

Sevan Matossian (02:16):

Yeah. Why not? Do you know what I’m saying? Like, I there’s gotta, well, I guess then you could just, it could just be endless. You could be like, well, the book that has the most, the documents, the most world records is the Guinness book. World’s records, I guess maybe there’s no end to it. I don’t know. Seems odd to me. I really like, I really like that as a record.

David Rush (02:37):

Yeah. The other, the other issue is not all records are made equal. I mean, I made broken 200 world records, but there might be one record that one person broke. That’s more impressive than all the ones I broke and put together.

Sevan Matossian (02:48):

All right. All right. All right. I won’t, I won’t beat the dead horse. Maybe I’ll circle back to it. Hey, uh, what’s interesting is, uh, I had a, um, I’ve had a whole, this show’s had a whole variety of people on it. And yesterday we, um, had Patrick bet David on it. He is a, um, a businessman entrepreneur and I was reading his book, um, your next five moves. But I think one of the things that I remember seeing in the book is is that if, if, if someone has a reason for doing something, they have endless energy and you, and, and not only do you have, and I, and I, uh, this may be, um, well, we’ll find out if you push back, but not only do you have a reason, but you have a chip on your shoulder from the second grade chip on your shoulder might be a little bit strong, but you had something happen to you in the second grade. Um, and, and also now you have a reason, a very noble reason. Can you talk about that about, about breaking your records?

David Rush (03:39):

Yeah, for sure. So I bring rate these records, remote stem, education, it’s science, technology, engineering, math, and, and the reason we need that is, is those are the, you know, Glassdoor published a couple weeks ago that the number one job in America and 24 out of the top 50 requires stem degrees. Either the jobs that they pay, the best that the, the hardest to fill, they give you the most work life balance, the most flexibility. And the problem is there’s just a shortage of people into those fields. And one of the problems is the stem subjects are hard. Math, science, engineering, and a student will fail a math test or struggle at science. And they’ll have this fixed mindset that says, you know, I’m not a math person. I could never become an engineer. And, uh, Stanford psychologist, Carol Black talks about this in a book called mindset.

David Rush (04:20):

And you can be that of a fixed mindset or a growth mindset. And in a fixed mindset, you’re born with talent skills and ability innate to you. And all you have to do is discover how good you are at those things. Like you take a test or you have somebody tell you, you try it out and it’s like, I’m good at this, or I’m not. And if you’re not good at it, don’t try it cuz you’re not ever gonna be good at. But in a growth mindset is this idea that you can become better at anything with no hard upper limit. And so this is what I’m espousing this growth mindset, um, in showing with a tangible example, that if you set your mind goal, believe in yourself and pursue with passion, you can accomplish virtue anything. And in second grade I tried out for the gifted program in school.

David Rush (05:01):

I took a test. I, I didn’t get in. I wasn’t smart enough. Does that mean I couldn’t become smart if I tried hard? Well, I kept trying and by fifth grade I did get in, but just for math, does that mean I couldn’t be good at science or history language or literature? Well, I kept working hard and by the time I graduated from high school, I was admitted into MIT where I got my electrical engineering degree. And so I had this Gretchen of being not smart enough to get into the gifted program in the public education system, in Idaho to go into the top engineering school in the world. And how did that happen? It was it’s because I believed I could get better. And I tell you if I’d have believed in second grade, when I took that test, that I wasn’t smart, I can guarantee you, I wouldn’t have gotten an MIT, but I didn’t U I didn’t let that test define me to saying I can’t do those things. I just kept looking hard through it. And I’m 37 years old. And what if I told you the day I turned and I, and I told you, I, well, hold over or have broken over 200 Guinness world records. Um, and what if I told you today, I turned 30. I had zero world records.

Sevan Matossian (06:01):

And how old are you now? You’re how old are

David Rush (06:02):

You now? 37 37. And at the age of thirties, when I started breaking what change, it’s not like I developed some sort of superhuman strength or ability at the age of 30 it, I developed this growth mindset. Um, and it’s also not that I just decided I want to, to break a Guinness world record at that point too. Cause I dreamed about this since I was a kid. I mean, that was like the pinnacle. That would be so cool. If I could break a Guinness world record, I even gave it, you know, a half try for a few records when I was a kid. And I was like, you know, those people have something I don’t, there’s no way I could ever break a record.

Sevan Matossian (06:32):

Which did you try as a kid? Which records did you try? Or did you consider trying?

David Rush (06:36):

Yeah, so one of ’em was a, I saw

Sevan Matossian (06:37):

Fat guy, fattest guy in the world, heavy guy in the world.

David Rush (06:41):

One of my thought was like the most, uh, glasses balanced on the chin. They got these pine glasses balanced to the chin and I’m like, I decent to balance. So what I did is I took my parents, you know, eight foot roll the carpet,

David Rush (06:53):

You know, the car rolled car board roll. So I’m putting this cardboard too of my chin, trying to balance it on my chin. I could, I just was able to keep it there for a few seconds. And I’m like, man, the glasses are gonna be harder. It’s gonna be too hard. I’m just gonna give up now. But what I’ve done since, you know, I’m a juggler and in college I decided, you know, I’m gonna add balancing to my repertoire. I started balancing things on my chin and now I hold the record for, you know, long balancing a lawnmower in my chin and or the furthest distance walked with a chainsaw on my chin, those sorts of things. Um, but that all happened because I had this growth mindset.

Sevan Matossian (07:28):

Uh, what was the name of the book or the, the author of the book and the name? Carol something you said

David Rush (07:32):

Carol Dweck, DW E C K. And the book is mindset. And it’s a, um,

Sevan Matossian (07:37):

You recommend it.

David Rush (07:39):

Oh, a recommend. I mean, it’s got of a million copies sold about the psychology of having a growth mindset, not positioning yourself as I can’t remember names or I’m not a appeal person. I can’t do sales. I’m not a dancer. I can’t draw, I can’t do math. I can’t become an engineer. If you have that, that’s called what’s called a fixed mindset. And there’s all sorts of research in this book that talks about not only can any, anybody can become better, anything, but just believing you can become better at something dramatically increases the rate at which you get better at that. Something

Sevan Matossian (08:11):

Let’s get a, um, one of my favorite lines in the entire world. Uh, and one of my favorite topics in the whole world is, uh, a statement by a gentleman, uh, by the name of LASU. He wrote the doted and he said, if you argue your limitations, they’re yours. And you know, what’s fascinating about what you’re saying. Not you can really, not only can you, um, um, uh, it’s interesting to call it a growth mindset, cuz you could convince yourself to be the person who’s least capable in the world too. That’s how strong the mind is. There is, is no homeostasis in what you’re saying. If you say it’s not you, you, it’s not like, you’re just like, Hey, I’m just, I’m I’m just nothing. You’re either or you’re good. It, it it’s it’s really so, so why would you ever choose? Why would you ever choose the limiting mindset ever when there’s there’s there’s no middle road. Yeah. But

David Rush (09:03):

Do you

Sevan Matossian (09:03):

Do that? You see what I’m saying? It’s FA it’s fascinating what you’re saying. I’m really like when I heard it the first few times I’m like, okay, yeah, yeah, yeah. I’ve heard this a thousand times, but as we delve deeper into it, like this is the problem with humanity. If this is the problem with our leaders, no one should be arguing any, you should not be arguing your own limitations as a human being. And no one should be arguing them for you. You don’t wanna be around people who are arguing your limitations for you. I have a wife and a mom and a sister. I, I don’t, it’s just interesting that it’s those three it’s three women. But, um, who believed in me, who always believe in me, who call me text love on me every single day and tell me how great I am and what I’m doing is good. And they gimme constructive C criticism too, half the podcast. My mom says she has to turn off cuz of my big mouth, but the other half she’s like, man, you’re really doing it.

David Rush (09:48):

Yeah, no that’s awesome. And, and it, and it’s not necessarily a new idea, but Greg brought into it as putting this name on it mindset and then gathering the re research to show it scientifically.

Sevan Matossian (10:01):

And, and but, but on the flip side, it’s the same thing that, um, uh, Matt Fraser, the fittest man in the world, he hung his second place. He hated his second place trophy when he first took second place, but he ended up keeping it and that’s the one he hung most prominent in his gym. So he can remember how much that suck to get second place. Uh, Patrick bed, David people. He, he, he got eight 80 on the, uh, S a T and a 1.8 GPA. And he, he Remi, he, he used that. Um, I can’t do anything as fuel. And you also have it. You have this second grade experience. Do you really remember that?

David Rush (10:36):

Yeah, no. I remember taking that test. I one, one of the most vivid members I had, it was, it was, I can tell you, it was at my grade school, in the modular building back, right. Go up the little ramp to get in. And there was a gal that was given the test and one of the tests was a puzzle. It was like an eight feet puzzle, eight piece puzzle of a soccer ball. And it was, I remember I had like curved edges and lined edges and I loved soccer and I just puzzled like eight piece. And I’m still, I couldn’t put it together. I was so mad at myself. It was like, I, I love soccer. This is only eight P puzzle. This should be so easy. I couldn’t do it. And so absolutely. I remember that test.

Sevan Matossian (11:08):

Do you think that you couldn’t do it because you froze under pressure? Like, were you like man, like I it’s, like I remember taking a spelling being like the third grade and the teacher asked me how to spell wood and she used it in a sentence and I spelled the wrong wood. I spelled w O O D and said, w O U L D and, and the whole time I’m spelling it. I knew I was spelling it wrong. I was choosing the wrong word and yet I just did it anyway. I’m like, was it like that?

David Rush (11:30):

No, no, not at all. In fact I, um, the reason I wasn’t couldn’t do it is cuz I’d never practiced it. It was a new type of puzzle I hadn’t been exposed to before. And, and this happens all the time when I’m trying to break a new record in a different category. If I, when I try something out, I’m often terrible at it. I’m nowhere even close. Like, uh, for example, the first time I went to practice the fastest time to pop three balloons with a nail blindfolded, uh, or with my head blindfolded. So I’m wearing a blindfold, I got a little nail attached to my head. I’m trying to pop three balloons. I’m out there in the garage. I set it up and the record’s something like four seconds. And I’m out there with a blindfold on swinging my head back and forth like this.

David Rush (12:06):

And my wife walks out, she’s laughing at me hysterically. It took me like 45 seconds. And I only popped one of the balloons. And this is what happens all the time. When we try something new, we try to take a layup or we, you know, take a test. And we’re, we’re under this situation where people can see us fail. And like when you fail, you’re like, I don’t wanna try that anymore. Cause that hurt that experience. Wasn’t good. I got made fun of, I don’t wanna put myself out there, but if you, again, approach this with a growth mindset, this is something I can get better at. I went on and broke that record and you know, know, I don’t know, a second, I broke all three balloons, took the record, but if I’d given up on that first try, would’ve had no idea what I was doing.

David Rush (12:40):

Cause I’d never practiced it. I wouldn’t been exposed to that before. Um, now I, you know, if you practice puzzles, you get better at doing puzzles. If you practice balloons, you get better popping balloons. If you practice math, you can get better at math. And there, there are way you can make your practice more effective. Like, you know, getting help when you get stuck. Um, trying, you know, having somebody that’s done it before repetition. And then when I’m practicing, like, um, physical acting, a, a athletic things like juggling or balancing, um, deliberate feedback is important. That idea of like measuring what you’re doing, get it on video, get timing for how long it takes if as a time. And then get that immediate feedback to understand is what I did helpful or not helpful.

Sevan Matossian (13:21):

Um, you, I had this, I had this experience all through growing up, uh, when they would pick teams in PE, um, there’d be two co there’d be two, you know, the PE teacher would be like, you know, and the eighth grade PE teacher would be like, okay, David, you’re a, a picker, you’re a team captain. And Joe, you’re a team captain and all the guys would get picked and then some girls would start getting picked and then I would get picked. And I was always like the, not only the last guy, but some girls would get picked. And, um, was it similar like that for you too? You like, you couldn’t catch a ball, like you, you were the, and, and I, I actually, I didn’t mind it for some reason. I was like cool with it. Like I never had it never made me, um, I, I didn’t care for, I don’t know why I should have cared. I should have like gone and hidden a hole, but I actually thought it was funny. Um, did you, did you have something like that going on? Cause I heard you say that you didn’t know how to catch and that’s one of the reasons why you chose juggling was to be like, okay, I’m gonna prove that. Not, I can’t catch a ball for, to save my life, but I’m gonna become the world’s greatest juggler. Yeah.

David Rush (14:18):

Yeah. So there was a, a couple things there and I’ll clarify the world’s greatest jugglers. I’m certainly not that, but I am

Sevan Matossian (14:23):

The world’s okay. My words, my words. Yeah. So,

David Rush (14:27):

So in, in grade school there was, you know, I had an older brother who was one year older than me, but also had a different, uh, chemistry makeup in his body. He was loaded with testosterone and he was shaven by grade seven or six. He best arms, best arms in school in the yearbook because his biceps were absolutely sculpted and he never lifted weights a day of his life. You know, he was really active and built stuff and, you know, lifted everyday things, but never lifted weights, but he was phenomenally a phenomenal athlete, won the city wrestling, neat, you know, fastest a hundred meter dash in junior high, um, set the school record in junior high for fastest mile. So I grew up under that shadow of being like I was, I was probably more like an average athlete. He was phenomenal. But then when I was playing football at school, we’d have, you know, the picking teams know when I was playing with, you know, the nerds I was okay.

David Rush (15:13):

But when I was playing with the kids that actually played football, the ones that practiced it, that had spent time on it, I would get picked last because they throw them with football and I get so nervous, I’d drop it. And, and so I was often picked last at grade school, uh, that recess for playing flag or two anti football because I was off the ball, but I’ve gone on, on now to become the world’s fastest juggle. I can get the most juggling catches in one minute with three balls. Um, and that’s, that’s another interesting story cuz when I first tried that record, uh it’s after I had broken a couple, I was like, you know what, I’m gonna try this. And I, I got my baseline. How fast am I? And then I practiced some more and then I practiced for a week maybe, and I didn’t really get any better.

David Rush (15:51):

I’m like, who am I kidding? There’s thousands of professional jugglers out there that are way better juggling than I am. There’s no a I could ever set this record. And at the time it was 422 catches in a minute. It’s uh, just over seven catches per second. And so I, I put it in the shelf for a while, but after I’d broken, you know, 5, 6, 7 records, I realized, you know, why don’t I approach this with a growth mindset, this idea that I can become the fastest juggler in the world. There’s nothing stopping me. There’s no hard upper limit. And so I started practicing deliberately getting immediate feedback over a period of time. And, and a funny thing happened is when I practiced, I got better. And when I believed I was gonna break the record, I got better even faster. And the more confidence I got, the more I practiced, which means I got better, faster. And um, in 2016 I ended up breaking the record of 428 catches in one minute. And so I was the world’s fastest other. And I was like, wow, this is so awesome. And a few months later, someone else broke the record at 502 catches in a minute. And I’m like, oh

Sevan Matossian (16:51):

Man. And do you know who this guy is? Like, are you guys email friends or, or internet friends?

David Rush (16:57):

Not that guy. Okay. But at that point I’m like, I’m not gonna give this up. And it was actually it’s you

Sevan Matossian (17:02):

Can Flo your teeth while you’re on the show, by the way, don’t let this show is we are free here. You do what you wanna do. I wanna see you do you do the first, but it’d be awesome if you did it.

David Rush (17:11):

I’ve got all sorts of stuff that I got my, uh, I got my, uh, arm exercises with these chopstick, the strength in my hands, while I’m sitting here, I got the juggling balls sitting here. I just got random things. But, um, it, so I, I go back to practice for world’s fast juggling. And this time I got 556 catches in it. It’s like nine catches a second. It’s crazy. When I thought seven was impossible and you know what happened? Another guy broke the record, Mike L Farrow, um, out of, I think Spain and he is one of the world’s greatest jugglers. He is one of the few. We juggle 10 balls in a performance. I do know him. We chat back and forth. He broke my record 550, 58 catch the night. And so I had to go back and practice again. And, and now I currently hold the record if 586 catches a minute, it’s almost 10 catches per second sustained for an entire minute. And this is when I thought seven was impossible.

Sevan Matossian (17:56):

And I noticed you changed the angle of your hands when you went for your most recent record, there used to be like this side to side oh movement. And now there’s this kind of like this, this like ones one’s like here dropping ’em in, right?

David Rush (18:08):

Yeah. So here’s the cascade juggling pattern. In fact, there’s two records. Now the, the fastest juggling with the cascade, which is what Guness used to require, but then they allow this what’s called the shower pattern where it goes around in a circle. Yeah. But when it goes around in a circle, you go through throw two balls at the same time. This one’s technically a little faster. So I, I, so this is, this is how I have 586 catches and have smaller balls and I gotta be warmed up for a bit, going around a circle like that. And then I also still hold the record for the most gentle catches a minute with the three ball cascade at 502 catches in one minute. So still substantially faster than I had before.

Sevan Matossian (18:43):

Hey, um, uh, one, one time I was looking up, I, I, I was to, to prove a point. I looked up this, there, there’s probably some name for this curve that, you know, it being that you went to MIT, but I looked up the, the, the curve for people who could juggle three balls and then four balls and then five balls and then six balls. And you just watch that number, just drop every time you, you add a ball and it’s crazy. And then you start getting to that upper top end of how many balls, you know, for the world record for most balls. And it’s just like one person, one person, one person. I mean, it’s nice.

David Rush (19:17):

Yeah. It’s an exponential to K curve. Um, on average, you know, learning how to juggle might take three balls might take on average about an hour. It could take, you know, a week or, uh, but E adding each ball becomes about 10 times as hard. So takes an hour practice to learn three. It’ll probably take you 10 hours to learn four. And so there’s a lot of people that know there are tons of people that juggle three, quite a few that can juggle four that maybe spent that 10 hours. The number of spent the hundred hours to learn how to juggle five is just virtually nothing. And then 6, 7, 8, 9, 10, 11 is the most that’ve ever been. 11 balls is the most has ever been juggled will. Um, and

Sevan Matossian (19:53):

Oh, I thought it went up to like 15. That makes me feel better. Cuz I saw, I saw that and I’m like, how can that be? Okay. I must have been looking at it wrong.

David Rush (20:00):

So there’s so juggled is qualifying juggling. You have to have twice as many catches as you have objects.

Sevan Matossian (20:06):

Oh wow. But

David Rush (20:06):

Juggled 11 ball, you need to have 22 catches. Now. I believe there’s the most ever flashed is means you throw all the balls up once and you catch ’em all as 14. Alex Baron is the one who’s done that. And so he’s throwing 14 balls in the air individually and caught all 14 them. And, and so 14 is the most of them flash there might have been. I, I think that’s the most for anything.

Sevan Matossian (20:28):

That’s incredible. Um, what do you eat, David? Have you changed your diet over the years?

David Rush (20:33):

Yeah. No, I’m, I’m not a particularly amaz a great eater when I was growing up. I didn’t really have a sense of like refined foods or bad for you, sugar bad for you. And I’m, I’ve got some weaknesses, like I’m a sweet tooth and I like diet soda. So those are my two main vices right now. But for the most part, I try to eat a relatively high protein diet, lots of fruits and vegetables. Uh, but you know, for morning, I, I really like my cinnamon toast crunch and lucky charms, but I put protein milk instead of the standard stuff.

Sevan Matossian (20:59):

Oh, you’re killing. Oh, you’re killing. I’m gonna say something crazy here to you. Um, your skin has gotten like, like there’s some, you look like you’re on the carnivore diet. Your skin is impeccable compared to where it was like five years ago. Some of the videos I seen I’m like, oh, this guy’s got some sort of like, um, uh, uh, like Paul Aldino Dr. Paul Aldino. I had him on the show. He had, uh, what is it? I forget what it is. But he had some where his skin would get really red and PEY and then he switched to the car diet. And I mean, your skin looks amazing right now.

David Rush (21:31):

Yeah. I don’t know about that. It might be the filter on the video, but um,

Sevan Matossian (21:34):

All right. You didn’t change your diet. You’re not a carnivore guy now.

David Rush (21:37):

I’m not, no, I wouldn’t call myself a carnivore. I do have a higher protein diet right now. Like I took my collagen powder this morning and I, and I make sure to get plenty of protein in my diet, cuz I find that helps me maintain my, um, you know, fit fitness level a little bit higher. And, and you know, LA year before last, like in October of 2020, I, I did my longest Guinness world record every year. I did the furthest distance traveled on foot while juggling and you gotta be juggling the entire time. You gotta be moving forward the entire time. And then what really threw me for a loop is Guinness says, nobody can feed you food or water. And I eczema

Sevan Matossian (22:11):

Eczema. Thank you, Melissa eczema. Yeah. You used to have eczema. You don’t got it anymore. Sorry, go ahead.

David Rush (22:15):

Nice. So I’m like, well I, um, so I, so I gotta carry, I can only run about 15 miles without food or water. So I had to wear a Camelback with me, stick my mouth, get some, you know, electrolyte drink in there to keep going. And I ran 20 mile miles straight while juggling. And after about five and a half hours, I finally dropped a ball which ended the attempt. Um, and then a year ago I had my, uh, appendix out. I had appendicitis and then some infections after that. So knocked off my fitness levels dramatically. And so last several months I’ve been trying to get back in shape. I’m going after some running fastest mile, fastest, a hundred records this week, a hundred meter dash.

Sevan Matossian (22:52):


David Rush (22:52):

And so I’m doing sprints and, and trying to get back in shape. And so I’ve, um, I’ve been working hard at that. And so I’m trying to eat a little healthier and I started on Christmas Eve. I started a new workout re regimen of every day. I’m gonna do 50 pushups and sits. Uh, and then every day I increased that number by five. Oh. And so yesterday was 425 pushups and 425 setups and today’s 430

Sevan Matossian (23:15):

Dude. You look great. Congratulations. That’s awesome. Do you have kids?

David Rush (23:20):

I do. I’ve got a three and a five year old voice and they’re a ton of fun.

Sevan Matossian (23:24):

Yeah. I have two, five year olds and a seven year old and I, and I, and I, I just can’t get enough of ’em. I just want to just party them. You must be. I, are they fascinated by dad? Are they figuring out what dad’s doing? Are they tripping?

David Rush (23:36):

Not really. I mean, they have fun with me. I mean, they’ll, they’ll juggle with me and they’ll do keep you up. And they want to bounce in the PO steps and the balance boards and they play with all the toys, but they have no idea. I mean they think the Guinness world record is my logo is my logo. They’ll see it. Hey dad, there’s their logo, but they have no idea that Guinness world record is supposedly this mystical cool thing that people do. They just think it’s part of life.

Sevan Matossian (23:58):

Um, are you, um, uh, disgusted by the soft sciences at all? You no, one’s listening. Let’s just talk me and you. There’s science. There’s physics. There’s biology. There’s these real hard sciences. There’s like four of ’em there’s math. And then there’s all this my words. It’s not yours horses out there. Do they kind of, um, um, do they bother you at all? Uh, sociology, sociology majors.

David Rush (24:27):

So I don’t know that they don’t, they certainly don’t bother me. There’s a place for them and there’s a lot of nuance. You’re a good dude in, in understanding now here’s the, here’s the deal. So one of the ones that fascinates me the most is actually psychology because it, you might consider it a soft science is not hard and fast rules because it’s how the brain works and how people think. And it, it’s not the state. It’s not repeatable and the same in every person every time. But statistically, you can draw bell curves about how this percentage of these people, this percentage of people are gonna react this way. This percentage are gonna react this way. And this percent react this way. I can’t tell you how indie each individual person react, but I can tell you on a whole, this is how people are gonna react to a situation.

David Rush (25:03):

And so psychology about how people have a, you know, or I’m just trying to come over with an example of, you know, fear like, Hey, when you’re in a fearful situation and you meet a cute girl, um, your heart rate increases, you start perspiring, your hands, get sweaty. And they a study on the Capano suspension bridge in, in, um, Canada, which is that tall suspension bridge in, in north America, maybe the world. And they, and they did a study where they had this girl give these people, uh, they met them on the bridge and gave ’em my name’s Ashley. Here’s the phone number, call me. And then that same girl says my name’s Emily. Here’s my phone number. Call me same phone number, different name at a different place in the park. And what happened is the guys that they met on the bridge called back way more often than they guys, she met off the bridge and the guys were like, thinking, Hey, my, my heart rate’s increased.

David Rush (25:52):

I’ve got perspiration and they’re attributing it to this girl. They’re meeting on the bridge is cute. And so they call back thinking, I must be attracted to this girl, but your body can’t distinguish those physical reactions from, um, being on a, from acute girl or, or, or, um, being scared cuz you in a bridge and it’s called the MIS attribution error. You miss ATT your attraction to this girl because you’re having the physical symptoms of it. And those are the sorts of things that kind of just absolutely fascinat me. And there’s tons of examples of in psychology about people and the way they think and how they treat people. And you know, if you, if you tell a student, you break a student, you know the class experience you can’t run anymore, but tell half the class you’re done and you, people are smart. The dumb people will start believing they’re dumb and the smart will believe in. They’re smart. Yeah. And it’s all psychology.

Sevan Matossian (26:35):

Yeah. You tell people they’re sick and they’ll start, believe they’re sick. You tell there’s people, there’s something to be afraid of and they’ll be afraid of it. Even if there’s not, it is a very we’re we’re seeing one of the most fascinating experience unfold right before our very eyes today. Um, does he have, uh, no. I wonder what his Fran time is no wrong one. Uh, does he have an in Instagram? Um, so I try, it takes a little while to get a hold of David Rush if to use Instagram, he’s kind of, he’s not, why are aren’t you a big Instagram guy? It seems like breaking world records is made for that platform.

David Rush (27:07):

So my, my, my process, I didn’t have, uh, notifications set for Instagram. I run all my social media channels and my, I have a full-time job. I am a product manager technology company and breaking records as a side hobby. And so I do that. I spend time on it, but um, on Instagram I didn’t have notifications, had all these messages backed up from people requesting, Hey, can you have me on the show or I wanna do an interview or I wanna say hi and I didn’t see any of them. So my, my Instagrams David Rush speaker, I believe

Sevan Matossian (27:35):

I’m gonna, I’m gonna see if I can, if I can. Yeah. My

David Rush (27:39):

It’s David Rush for stem.com David Rush for stem.com. And then there’s a popup on my website that has all my, you know, Facebook, Twitter, Instagram, YouTube, um,

Sevan Matossian (27:47):

That look right. Look, I changed your name. Does that look right?

David Rush (27:51):

Yeah. That’s my Instagram at all.

Sevan Matossian (27:53):

Bam. There we go. Uh, when you were doing the slowest juggling, your heartbeat went up to 180 5 for, uh, the slow will, will you explain to people what the, what the slowest juggling is that one minute record that was fascinating to me that your heart rate went up like that, that looked, that looks really hard by the way, that looks really, really, really hard.

David Rush (28:15):

Yeah. So we talked about the world’s fast juggling. The most juggling catches a minute. The flip side of that is the world’s slowest juggling. The fewest juggling catches in a minute. And the obvious loophole everybody thinks about is, well, don’t juggle. Now you gotta be juggling the entire time, which means you gotta have three balls. And one of them in the air at all times, and a second one in the air as, um, as you’re juggling and to do that, obviously the there’s two main components of it. One is you gotta throw the ball as high as you possibly can. And so when I broke it, I did it at the Boise state blue turf, the football field. Yes,

Sevan Matossian (28:46):

A cool video by the

David Rush (28:47):


Sevan Matossian (28:47):

Space. Very cool video.

David Rush (28:49):

And, and I was throwing the balls about one and a half times, the height of the field go post. So throwing the balls as high as you possibly can, and it’s gotta be accurate because its pretty much straight up cuz even, you know, one or two degrees off, you gotta take a couple steps to get back in the position, catch it about four or five, six degrees off you’re running off the, the field and it’s impossible to catch. So run it, throw it as high as you can possibly straight up. And then the second piece is you gotta maximize the, um, uh, unique hang time of each ball, which means you have to wait until the last possible moment when this ball’s coming down before you throw the next one. And so throw a ball as high as you can wait until the last ball possible moment, throw this ball up at the same time, the speed differential then between my hand and the ball coming down is about 70 miles an hour. And then absorbing those 70 miles an hour to get it to zero as smoothly as possible. So I don’t get it bruised. And so I was able to do that. I got down to 22 catches in a minute, which is about three seconds of hang time per ball and up jumping while I’m throwing, I’m getting my whole body into it. And so physically exertion it’s more

Sevan Matossian (29:50):

And grunting you’re grunting

David Rush (29:52):

You grunt. I mean just, it was absolutely absolutely exhausting. And my resting heart rate as a runner was about 50 beats per minute. And by the.
