Today, on something you should know, there's something you're doing in the kitchen that you can just stop and it'll save you a lot of time.

Then, the desire for social status.

It's something we all care about.

Everyone who doesn't care about status in one walk of life cares about it in another one.

So you can be really, really high status in one world and be unimportant in another world.

Or just an average Joe.

Then, do you have people take off their their shoes before they come into your home?

And your vestibular system.

It's the thing that keeps you from falling over, and the way it works is amazing.

It's a system that a lot of people don't know about.

We're taught that there's five senses, but that's not remotely true.

We have a lot more, and the vestibular system is a really important sense most people aren't even aware of.

All this today on something you should know.

You know, I remember the first time I had to hire someone.

I thought it would be quick and easy, but posting on random job boards and sorting through applications and waiting for the right person, it took forever.

And I never thought I was very good at it.

Something you should know with Mike Carruthers.

So I'm going to start this episode by saving you a little bit of time every day for the rest of your life.

Hi, I'm Mike Carruthers and we're just getting started on this episode of Something You Should Know.

So after every meal in your house, you probably get up and rinse off your dishes and put them in the dishwasher.

So every day you're spending time doing something you do not need to do and you should stop doing it from now on.

And here are the four main reasons why.

Your dishes need to be dirty for the detergent in the dishwasher to do its job.

The makers of the dish detergent cascade discourages customers from pre-washing or rinsing dishes because it actually inhibits the cleaner from working.

Enzymes in cascade detergent are designed to attach themselves to food particles, according to the Wall Street Journal.

So without the food particles, the enzymes have nothing to latch onto.

Secondly, you won't get your dishes any cleaner by pre-rinsing them.

Today's newfangled dishwashers are very savvy.

They have advanced sprayer technology and sensors to detect how dirty your dishes are.

Pre-rinsing or washing dishes by hand wastes water and electricity.

You actually waste about 6,000 gallons of water per year if you insist on pre-rinsing your dishes, according to consumer reports.

And as I said, it's a needless time suck, especially when you probably have other things you'd rather do.

And that is something you should know.

You have probably noticed that people, humans, seek status, social status in their group.

And sure, you see people trying to flex their status with a fancy car or nice jewelry or a gorgeous home.

Those status seekers are easy to spot.

But we all want status in our group because when you have status, you have resources.

And when you have resources, well, then you're all set.

Toby Stewart is someone who has studied social status and the people who seek it.

Toby is a professor of business administration at the Haas School of Business at UC Berkeley and has previously held professorships at Harvard, Columbia, and the University of Chicago.

And he is author of a book titled Anointed: The Extraordinary Effects of Social Status in a Winner-Take-Most World.

Hi, Toby, welcome to Something You Should Know.

Thrilled to be here.

Thanks very much, Mike.

So it is very easy in our culture to see people in pursuit of status.

People want it.

They want the nice car, or the nice house, or the corner office, or the best table at the fancy restaurant.

Because why?

What does that get them besides a sense of satisfaction that they got it?

But when people get it, when they have the status they've been seeking, is that satisfying?

Is that the end?

Or is that just the beginning of a race to get more of it?

Boy,

that's a great question.

Do we want high status?

Do we want more status?

The general answer is yes.

And for nearly all of us, if you could make the choice, do you want to be high up in the

status hierarchy or do you want to be down by the bottom?

It's a pretty obvious answer.

You want to be high high up in the hierarchy.

So

in a relative sense, high status is better than low status

in kind of all walks of life.

But it's a lot more complicated than that.

It's easy to look at people who have high status and be envious and think, boy, I wish I was like them, right?

I had the recognition that they have.

But it's not always that easy.

And there are a bunch of downsides for being prestigious.

And one of them is

what you just alluded to, which is once you get high status in whatever domain you got that, it might have been a lot of work to get there.

And you think, you know, you think like the hard work is getting up to the top.

But it turns out that once you're there, you often have to work even harder to maintain your position.

Ooh, well, can you give me an example of that where it's hard to maintain your status?

First one that pops into my mind is Michelin starred chefs.

So, you know, the Michelin star is like the Nobel Prize in the culinary world and

very much a recognized honor if you're a chef or restaurateur.

And so there's this, you know, incredible effort that people in the business go through to try to get the star.

But then when you get the star, it's re-evaluated every year.

And so then you're in this position where, okay, I got it.

This was what I've been aspiring to do.

But all the time, restaurants, so if you know the system, restaurants can get one, two, or three stars.

Three stars go to two stars, two stars go to one star, one stars go are removed from the list.

And so you get there, but then the expectations on you become very, very high.

The clientele changes typically.

What the clientele expects of you changes.

And it becomes a kind of a lifelong pursuit to maintain the status that you've already acquired.

But when you first get it, boy,

that's a high.

That's great.

But now you got to fight to keep it.

I actually found there's a whole number of Michelin star chefs that actually just voluntarily returned the star, kind of

called up the guide and said, hey, you know, you can have it back because they didn't want the pressure and they didn't like the changes that having

that status brought to the work that they were doing.

I don't want to spend too much time on restaurants, but you know what I've always wondered about?

So there's trendy restaurants that all the celebrities go to.

And I have never understood: is it a trendy restaurant and that's why all the celebrities go there?

Or it's because all the celebrities go there that it's a trendy restaurant.

God, I love that question, Mike.

I mean, I just love that question.

So you're getting at one of the super interesting aspects of status, which is it flows across affiliations.

It's this very interesting resource because for most resources, if you have them and you use them, they're depleted, right?

So if you have money and you spend it, you have less money by whatever amount you spent, right?

So you had the resources, you allocated it to something, the resource is gone after you spent it.

But that's not true for status.

So if you think about,

I don't know, Harvard University.

So Harvard University every year issues a whole bunch of degrees to people.

Those degrees are a conference of status onto the recipient.

But it isn't as if each time Harvard prints a diploma, it loses a chunk of its status.

But that's because, and here's where we come back to your question.

That's because Harvard's pretty careful about the students that it selects.

The university gives its status to the kids who attend.

And so it actually, in your restaurant example, is probably reciprocal.

So it might start out as the celebrity has status and gives it to the restaurant.

But once a bunch of celebrities show up at the restaurant, the restaurant acquires status.

And then another celebrity walks in and we're in the reciprocal world.

And when the celebrity shows up at the restaurant and by doing so confers status to the restaurant, the celebrity doesn't lose status.

He doesn't forfeit status and give it to the restaurant.

It just perpetuates.

It can perpetuate.

It is potentially ending.

And the reason that it perpetuates, and this is the sort of the, you know, insofar as this is a rational system,

let me give you the logic of the rationality.

So imagine you're a super prominent celebrity, doesn't matter who,

Tiger Woods or

Serena Williams, and those people have a business.

And the business is being really, really good at whatever sport or activity they do, but they have a separate business, which is an endorsement business.

The endorsement business is about kinetic status, right?

So, the idea, if you're Nike and you have Tiger Woods and Serena Williams on your roster, the idea is you're willing to compensate them a lot because they're super prominent athletes and they'll lend their prestige to the brand.

But if Nike were an absolutely terrible product, so if the product that a celebrity endorses or the restaurant the celebrity goes to or the student that Harvard University admits are really bad versions of those things, there's actually a loss of status that occurs.

There are some people, though, who seemingly don't care about status, even though, as you pointed out,

it seems innate in organizations, communities, whatever.

But there are some people that seemingly just, I don't care.

It doesn't mean anything to me whether we eat at this restaurant or we go to McDonald's.

So that's absolutely true.

There are some people who really don't care about whether they eat at that restaurant or

they eat at McDonald's, whatever that restaurant is.

But that doesn't mean that they don't care about status.

That means they don't care about the status of the restaurant.

So go to some other walk of life.

And, you know, I don't, you know, it kind of depends on who this person is.

But everyone who doesn't care about status in one walk of life cares about it in another one.

So you can be really, really high status in one world and be unimportant in another world or just an average Joe.

So you might be at work, you know, the really prominent person, the big boss up on top of the hierarchy.

But when you go to parent-teacher conferences at your schools, at your kids' school, everybody's kind of the same.

We're talking about social status and why we all seek it in one form or another.

My guest is Toby Toby Stewart.

He's author of the book Anointed: The Extraordinary Effects of Social Status in a Winner-Take-Most World.

You know, it usually takes a lot for me to get excited about clothes shopping.

But with fall and cooler weather coming, I'm actually looking forward to stocking up at Quints.

See, they've become my go-to for fall staples that actually last.

Cashmere, denim, boots, you name it.

The quality really holds up, and the prices are a lot lower than you'd expect.

Because, see, here's the thing.

Shopping online, my biggest worry is always: is it really going to look and feel as good when it shows up as it did online?

Well, with Quince, it always does.

I've got a couple of their 100% Mongolian cashmere sweaters.

They just start at 60 bucks and they are unbelievably soft.

Their denim fits great and wears really well.

And their leather jackets, I haven't bought one yet, but that clean classic look without the big price tag is very enticing.

And what I love is that Quince works directly with ethical factories and cuts out the middlemen.

So you're getting top quality fabrics and craftsmanship for about half the price of the fancy brands.

I've got polo shirts from them I practically live in, and people ask me all the time where I got them.

And I just ordered a new dress shirt look if you want to keep it classic and cool this fall upgrade with long-lasting staples from quince go to quince.com slash sysk for free shipping on your order and 365 day returns that's quince.com slash sysk free shipping and 365 day returns at quince.com slash sysk

so toby there are people who seek status by doing things like wearing a really expensive watch or driving a really expensive car.

But there are a lot of people who think that's ridiculous.

That, you know, my Timex will keep just as good time, or my, you know, 20-year-old car will get me to where I'm going.

So they think this person seeking status is really foolish.

They don't respect that status.

Here's another funny thing about status.

There's as many status distributions, status hierarchies, as there are social groups.

So it's not as if there's just sort of one global status hierarchy, which we all agree on 100%, and

we're all ranked in that one global ordering.

There's a really interesting academic literature, and it basically shows if you take

any number of random people and you put them into some context, call them a group.

So you're running a psychology experiment or

you have a meeting of the students in a yoga class or you have, it doesn't matter, like just random people, they're in a room.

Let's say they don't know one another beforehand

and they're unlikely to have much to do with one another afterwards.

Those people form a status hierarchy.

And they do it even if they're children.

So we have this sort of evidence that people sort into groups, they recognize, they defer to one another in those groups.

And so if you think about that, we have all of these status hierarchies.

And you and I,

we're different people.

We care about different things.

We do different things.

We face a different reward structure.

And I don't know whether I'm with you or without you on this.

I don't find very expensive cards to be significant status symbols.

And I feel the same way about watches.

But, you know, I live in, part of me is an academic.

so I live in the very status hierarchical academic world.

So I think about papers and publications and citations and university rankings and faculty achievements, and that creates a status ordering in my world.

And then there's one in your world.

And whether or not we buy into the luxury goods market as a status hierarchy, many people do.

And of course, that's what underlies

the luxury goods business.

Many people feel about themselves in just the right brands or in the right car, wearing the right watch, whatever right means.

But that doesn't mean all of us feel that way.

To say that we don't feel that way, however, doesn't mean that we're unattune to or don't care about status.

It just means that we don't care about that particular kind of status.

Well, it's interesting that you say that everybody seeks status in their own world, in their own status world.

Status is important.

But often when you talk about status to people,

it's often referred to in a derogatory way, that we all seek status.

But when we look at other people seeking status,

we find that distasteful.

It's gauche.

It's, you know, he's just trying to impress people.

Many of us also have this view of, I shouldn't be a status seeker.

Like, it's socially unacceptable.

It's bad behavior.

It's self-interested behavior, you name it.

And so although most of us really are status seekers and in many domains of

life, we are anti-status in others.

Talk about the relationship between status and money.

There has to be a relationship because money seems to, if you have money,

It would seem in almost any status group, it kind of gets you to the front of the line.

So there's got to be an important relationship here.

Yeah.

So positive correlation and not a perfect one.

Occupations is one example.

There are some occupations that pay really well, but they have lower status than, say, doctor or teacher that are, you know, old, venerable professions, but they might compensate less than some job and finance, but have higher status sort of in the eyes of many people.

Though the general point really does stand, which is that resources go to high status people.

You know, so like in my world, which really, really is a status system, if you're a prominent academic and you apply for a grant, you're probably a lot more likely to get the grant than somebody who doesn't have a reputation for status.

That's true even in a hypothetical world where you submitted exactly the same grant application as somebody else.

So if a high status person and a low status person submitted literally exactly the same grant application, it would be more likely granted to the high status person.

And in that sense, status converts to money, and we see that all over.

So it's not like a strict relationship, but generally speaking,

the resources flow to high status actors.

One area where status seems to play a big role is in the art world, right?

If you own

well-known art, if you have a a Rembrandt or a Monet,

just owning it gives you status that people who don't have that don't have in that world.

But there are plenty of other people who couldn't care less whether you owned a Rembrandt or a Monet, but in that world, it does seem very important.

The reason for that is that the context in which status tends to matter the very most are contexts in which it's really, really, really difficult to evaluate something directly.

And art is just perfect for that.

Like you look at it, you walk into a gallery or you walk into a museum and

you look at a piece of art on a wall or a sculpture and ask yourself, is this an excellent piece of art?

And how do you answer that question?

For most of us, we really struggle with that.

Like

we might enjoy a piece of art more or less, but

that doesn't necessarily tell us what we think about the quality of the art.

And so it turns out that when that's the case, and it's true in every cultural market, but it's also true in a whole bunch of areas that you wouldn't expect, like science and technology.

When we have evaluative uncertainty, when we look at a product and we just don't know how good it is, we tend to default to rather than evaluating the product, we evaluate the person or the entity associated with the product.

And by that, I mean, if I walk into a museum and I see a piece of art, I don't know if the art is amazing or not, but I've been told all of my life that Matisse is an amazing artist or Rembrandt is an amazing artist, or

you pick whatever artist

you've read or heard about.

And you have very much a strong association with the quality of the artist.

That you do know.

And so you assign the quality of the art, of the artist to the art itself.

Lastly, is seeking status,

because you had mentioned the Michelin chefs who give back their Michelin ranking because it just isn't worth it.

Is seeking status often not worth it?

Is it often empty?

Or do people find it quite satisfying?

Great question.

And

there isn't one answer to that.

So Michelin chefs, for example, the majority of Michelin chefs will tell you that they wanted the star, they worked for the star, they're honored to have the star,

and that their lives are better because of it.

So the majority will say, I wanted the status, I sought the status, I received the status, I benefit from the status.

But nearly all of those will,

one, have the view that it isn't quite the land of milk and honey that they thought it would be.

That is, there's a bunch of downsides that they hadn't really thought about or realized when they were in pursuit of that recognition.

So,

there are some amazing things that come with it, but there are also some negatives that they hadn't thought very carefully about, and they realize once they get there.

So, it's a so when we look at the high status, I guess another way to say it is the grass often looks very green over there.

But when we get there, we realize

there's some drawbacks of this.

But the majority of people will choose the status.

Most people who acquire a status really don't want to give it up.

What is it about status that you find really compelling that we haven't talked about yet?

Status has almost a self-fulfilling prophecy to it often.

And there's a lot of reasons for that.

And we probably don't have time for me to go into all of them.

But the gist of it is that we often end up in these circumstances where if you go to the starting point and we have a group of people, let's say they're competing or they're, you know, it's a workplace and people are trying to get ahead,

these very little differences in the early days can lead to dramatically different outcomes in the long term.

And that's the self-compounding dimension of status, where if you get a little bit ahead in the status race, people then start to recognize you as high status.

They start to evaluate your work through the lens of you're a high status person,

and they start to provide more resources to you, which then just provides an advantage to you

as you move into the next round of competition, so to speak.

And we see that in all walks of life, including, by the way, athletes, like the number one ranked athlete tends to have a whole lot of advantages entering the tournament.

And in that way, status becomes something of a self-fulfilling prophecy.

That's so important because at the end of the day, it really affects how meritocratic the system is.

So let me leave you on that one.

Well, that's a great point because we like to think that everybody has a shot, right?

Everybody, it's a level playing field in, say, a tennis tournament or whatever.

But really, the champion has an advantage.

They have probably the best coaches and trainers, the best equipment.

They just have more advantages because they have have been given those resources that someone just coming up never has.

And there's only, it doesn't matter what you're talking about, when you're ranking people, there's only one number one rank.

Well, this has been some great insight into the status seeking that we all participate in and that we all see around us every day.

I've been talking with Toby Stewart, who is a professor of business administration at the Haas School of Business at UC Berkeley, and the name of his book is Anointed, The Extraordinary Effects of Social Status in a Winner-Take-Most World.

And there's a link to his book in the show notes.

Chronic migraine, 15 or more headache days a month, each lasting four hours or more, can make me feel like a spectator in my own life.

Botox, onobotulinum toxin A, prevents headaches in adults with chronic migraine.

It's not for those with 14 or fewer headache days a month.

It's the number one prescribed branded chronic migraine preventive treatment.

Prescription Botox is injected by your doctor.

Effects of Botox may spread hours to weeks after injection, causing serious symptoms.

Alert your doctor right away as difficulty swallowing, speaking, breathing, eye problems, or muscle weakness can be signs of a life-threatening condition.

Patients with these conditions before injection are at highest risk.

Side effects may include allergic reactions, neck, and injection, side pain, fatigue, and headache.

Allergic reactions can include rash, welts, asthma symptoms, and dizziness.

Don't receive Botox if there's a skin infection.

Tell your doctor your medical history, muscle or nerve conditions, including ALS Lou Gehrig's disease, myasthenia gravis or Lambert Eaton syndrome, and medications, including botulinum toxins, as these may increase the risk of serious side effects.

Why wait?

Ask your doctor, visit BotoxchronicMigraine.com or call 1-800-44-Botox to learn more.

Think back to when you first tried to ride a two-wheel bike.

It was tough.

It was hard to maintain your balance.

But every day, most of us get up on two feet and walk through the day with no problem.

We maintain our balance.

You can probably stand on one foot and hold your balance for a while.

So how does that work?

With only two feet, you'd think people would be falling over all over the place.

Well, it's all because of an amazing system in your ear.

It's called the vestibular system, and how it works is nothing short of amazing.

Here to explain it is Dr.

Jeffrey Sharone, who is the director of the Balance and Fall Center and an associate professor at the University of California, San Francisco.

He's author of a book called The Great Balancing Act, an insider's guide to the human vestibular system.

Hey, doctor, welcome to something you should know.

Thank you so much for having me.

So this system, this balancing system that prevents us from falling over and allows us to move through the world,

how does it work?

The balance system

is comprised of several different parts that come together to enable us to be able to balance and move safely.

And it's one part is our ability to see.

and one part is ability to feel the ground beneath our feet.

And then the other part, kind of the hidden part in our inner ears, is our ability to sense head movements and body movements.

And that's called the vestibular system.

And it's a system that a lot of people don't know about.

And it's a system that we're not even taught about.

We're taught that there's five senses, but that's not remotely true.

We have a lot more.

And the vestibular system is a really important sense that most people aren't even aware of.

I suspect everybody has heard, I have heard, that the ear, the inner ear has something to do with balance.

I've always heard that, but I never understood it.

I don't know how the ear impacts balance, but how does it

the inner ear is an interesting area because it contains two separate functions that are related.

And it contains the organs of hearing, which is called the cochlea, and it contains the organs of balance which is called the vestibular system and they're located in the same area

because they share the same biological technology basically the hair cell and the hair cell is this remarkable cell that can sense fluid movements at a microscopic scale and it turns out that that enables you to hear sound, which is vibrations of air and then fluid molecules, but also it enables you to sense gravity by having a heavy sensor that then deflects the hair

cells and also enables you to sense head turns.

So they're located in the same area because they share the same machinery.

So say that one part again, because I'd never heard this.

What hearing

has to do with fluid movements, liquid movements.

What is that?

So the way hearing works is that when i talk when you talk when any sound is made uh we're really vibrating air molecules all around us and that vibration passes as a wave through uh the air that surrounds us and then it hits someone's eardrum and the eardrum begins to vibrate and it sends those vibrations along the little hearing bones to the inner ear and at that point the sounds are amplified because there's a transition from air molecules vibrating to the bones vibrating and then to the fluid in the inner ear vibrating.

And those fluid vibrations in the inner ear are able to be sensed by these remarkable hair cells, and they can literally feel the movement.

And because of that, they can send a nerve signal to the brain indicating that you're hearing something.

I never knew that.

And that's a remarkable system.

It makes you wonder how it even works because there's so many pieces to that system.

So I can understand this.

You said that in the ear, the ear is responsible for hearing and also this vestibular system for balance.

But are they two independent systems or do they affect each other?

Does a deaf person have trouble with balance because they're deaf?

Or these are just two systems that just happen to be in the same place in your head?

They are two systems that are in the same place in your head because they both rely on having hair cells.

But because of that, some diseases affect both of them.

For instance, if you get an infection in your inner ear, you can lose hearing, but also feel like you're spinning around and lose your sense of balance.

Or there's a classic disease called Meniere's disease, which causes people to lose hearing and also to experience pretty vicious attacks of vertigo.

And there's even some interesting rare diseases where people will both get vertigo with loud sounds, but also hear their eyeballs moving.

And it's because the hearing and balance mechanisms are located in the exact same space.

So we've all had the experience of losing our balance.

Everyone's lost their balance.

Why do people typically just suddenly lose their balance?

It's important to keep in mind that certain diseases can affect the balance system and the inner ear.

And

two of the most common of them that are pretty likely that you know someone in your life who has them

are the loose crystals disease, which we call by an acronym BPBV.

And also, there's a form of migraine that causes vestibular dysfunction.

and we call that vestibular migraine.

And those two diseases are incredibly common.

The inner ear has two basic parts, one that senses gravity and one that senses head rotations.

And the part that senses gravity relies on having crystals in their inner ear.

And when you look at them under a scanning microscope, you see there's literally crystals there.

And they're designed to be heavy, so that they're heavier than everything around them.

And they weigh on these hair cells and tell you where gravity is.

Well, when you're sick, when you have a head trauma, when you have infection or inflammation in your ear, or sometimes just with aging, they can dislodge from their usual location and end up in the other part of the inner ear where you sense head movements.

And that can trick the ear into thinking that it's spinning around really quickly when it's not.

And that's what happens with the loose crystal disease or BPBV.

You know, I've always wondered is like, what is this that system

that keeps your balance and senses movement and all of this?

What goes on when you say go to Universal Studios and go on one of those rides where you're actually sitting still, but you feel like you're moving, but you're not moving?

Like, does the system go, what the hell is going on here?

Absolutely.

Yeah.

So our

vestibular system,

like many of these systems, is designed for terrestrial life on Earth

in a natural environment.

And therefore, it can be fooled, just like there's visual illusions, there can be vestibular illusions.

And we generally rely on having reliable visual input.

that corresponds to vestibular input.

So if you're on one of those rides where you're surrounded by a screen and your whole visual field, everything you could see is moving, the visual system is making you think, oh boy, there's a real stimulus there.

We are moving.

And your vestibular system is saying, hey, wait a second, I don't sense any movement.

And that disconnect between what you're seeing and what your inner ear is feeling is thought by many to underlie motion sickness.

And that's why there's some people who really don't enjoy those rides.

The same mechanism would apply for being on a boat and getting seasick because your inner ear on the boat is saying, hey, we're rocking up and down.

But your visual system inside the boat is saying, no, we're in the same position in the room.

We're not really moving.

And that discordance, your brain doesn't know what to do with it.

It thinks you've been poisoned.

So it makes you feel nauseated.

Wow, that's really interesting.

But, and is there, maybe this hasn't been studied, but like if you do that a lot, if you work on a ship or if you, if you're constantly on rides at the amusement park, is there any long-term effects or the system just deals with it in the moment and then you move on?

You know, I did come across one study looking at long-term effects, and it turns out that your brain can rearrange itself in a sense and change to get you used to

these sort of discordant

things that make you feel nauseated.

And the study was done in

whirling dervishes.

So, whirling dervishes is a branch of Sufi Islam where, in order to meditate and get closer to God, the whirling dervishes will spin around for hours and hours.

And there was one study looking at their brains, and they found that certain brain areas that are responsible for integrating this visual information and the vestibular information were smaller than they ought to have been.

And it was probably an adaptation to allow them to keep spinning for so long without getting nauseated.

Yeah, but

I wonder if...

Because I've talked to people who work on cruise ships and whatnot, and they eventually get pretty used to the motion of the boat.

Does that affect them when they're on dry land and they're not bouncing up and down?

Or the body just adapts?

In most cases, the body does adapt, but there is a rare disease.

It's a French term, so forgive my pronunciation called mal debarcment.

And it's

translated as the malady of disembarkation.

And basically, it's a disease where you adapt to being at sea like on a cruise ship but then when you get off the cruise ship you continue to feel a sense of rocking and swaying and that could last for months or years

and let me tell you one other interesting thing about being on a boat and feeling

feeling

seasick is that people without a functional vestibular system so people who whose vestibular system simply doesn't work do not get seasick.

And it's thought to be that because their vestibular system doesn't work, there's no conflict with their visual system.

So they simply don't experience seasickness.

So you know that sensation you get when you go down an escalator and you get to the end and then you step off and you feel a little uncertain for a second?

Is that this?

Is that what we're talking?

Is that the same thing?

That is part of the vestibular system.

There's a little tiny organ in the vestibular system that senses up and down

movements in a straight line, linear movements, called the saccule.

And that is what is sensing when you're going up and down in an elevator.

But there's an interesting illusion that happens.

So the vestibular system is designed to sense accelerations, but it does not sense velocity.

So it only senses changes in acceleration.

So if you are moving in an elevator, at first you sense the movement, then you reach some speed and there's no more movement, so the vestibular system turns off.

When you hit the bottom of the elevator, even though you're not moving, there is an acceleration because all the fluid in the inner ear has inertia and it activates the sensor.

And that causes a bit of a false sensation.

And I think that's what you're describing.

So it is common.

well, I don't know how common it is, but you hear about

when people get older, they're prone to falling.

Are they actually prone to falling more because of what we're talking about?

Or is it that the consequences of falling when you're older tend to be more severe, and that's why it's a concern?

Vestibular dysfunction, so a loss of the normal function of the vestibular system in the inner ear is a risk factor for falls.

It's not the only risk factor, but it is one of the things that make falls more likely.

One of my mentors did a study looking at various risk factors for falls, including decreased vision, decreased muscle strength, and decreased vestibular function, and found that the vestibular system was one of the strongest predictors of fall risk.

Is the vestibular system something you can make better, or it just does what it does?

You can't, it's not like a muscle you can build up or

not.

One of the main treatments for a whole variety of different vestibular diseases is vestibular physical therapy.

So, the same way you can do physical therapy when you hurt your shoulder to strengthen the muscles around it, you can do physical therapy for your vestibular system to try to strengthen the reflexes and also to train the brain to get over the original problem and move past it and use other strategies and other body systems to compensate.

So vestibular physical therapy is really important.

Other than that, we're at an interesting moment in time where some people have heard of a cochlear implant.

A cochlear implant is a device placed in the inner ear that replaces the inner ear and allows someone to hear through the device by having a microphone connected to electrodes that stimulate the hearing nerve directly and give someone back a sense of hearing.

Well, right now, there are human trials for a vestibular implant.

A vestibular implant would be a device placed inside your skull, connected to these vestibular nerves that would replace a sense of balance.

And so far the trial is going pretty well.

So it seems like in the future we will be able to offer patients a vestibular implant to replace a sense of balance if it's been lost.

Just to have a sense of this, what percentage of the population has a problem with their vestibular system?

In any given year, about

10% of the population will report that they have a problem with dizziness or imbalance.

Not all of that is the vestibular system, but a lot of it is related to vestibular problems.

You know those people who walk on tightropes, so their balance must be really great.

How do they do that?

Is that related to this?

That

it's an interesting question.

You probably need a pretty functional vestibular system

in order.

We do see that when we look across different animal species.

For instance, if you look across big cats,

the cat with the largest vestibular system

is the cheetah.

And that makes a lot of sense when you consider that the cheetah, when it hunts, achieves the fastest speeds of any land animal.

And if you try to imagine how does it keep its eye on its prey when it is running across the savannah at 60 miles an hour, and it needs to be able to steady its eyes eyes despite the fact that its head's bobbing up and down.

And one of the cardinal functions of the vestibular system is to keep your eyes steady as your head and body move.

And so it makes a lot of sense that the cheetah has this extraordinary vestibular system

because it needs to in order to engage in these high-speed chases.

What else about this topic, since you clearly know an awful lot about it, what else about this do you find or people people tell you they find this very interesting that we haven't talked about yet?

We've divided modern medicine into different specialties, and the vestibular disorder seems to fall right between my specialty, ear, nose, and throat, and neurology.

And I think that's to our detriment because these disorders causing vertigo and dizziness and imbalance affect so many people

around the world.

And when you start looking looking at not just the fact that we can diagnose and treat some of these diseases, but when you start looking at the importance of the vestibular system across different areas of life, whether that be, you know, for car sickness, whether that be for pilots who are all trained to understand the vestibular system so that their vestibular illusions don't cause a plane to crash, or whether it's for astronauts because half of the vestibular system doesn't work in outer space.

So astronauts become disoriented and half of them end up projectile vomiting on their first spaceflight just because their inner ear can't understand a world without gravity.

It turns out that it's a pretty important system.

Well, as you said in the beginning, you know, we're taught we have five senses, but we have a lot more.

And this vestibular system is one of them.

that sense of balance that it gives us.

And I never knew about it.

I don't think most people know much much about it or how it works, but we do now.

Dr.

Jeffrey Sharon has been my guest.

He's the director of the Balance and Fall Center and an associate professor at the University of California, San Francisco.

His book is called The Great Balancing Act: An Insider's Guide to the Human Vestibular System.

And there's a link to that book at Amazon in the show notes.

Doctor, appreciate you coming on.

Thank you.

Awesome.

Amazing.

Thank you so much for doing this.

I've certainly noticed more and more people asking that visitors take their shoes off before they come in the house.

And even people volunteer it.

Would you like me to take my shoes off before I come in?

It has become more commonplace, but if you're still not one who has people take their shoes off, here are some reasons to consider it.

Tracked in carpet dust is one of the major sources of home exposure to lead, allergens, bacteria, fungi, volatile organic compounds, and pesticides.

A large portion of all the house dust in your house comes in on people's shoes.

Up to 94% of all the junk on your shoes comes off with the first two steps into the house.

Things like lead, pesticides, coal tar from your driveway all get tracked in on the bottom of shoes.

And carpets are kind of like sinkholes for these things.

Once in, they're hard to get out.

So if you have children crawling around on the floor, this is a problem.

Having people take off their shoes before entering your house will eliminate a lot of this stuff from coming in.

If the no shoes rule is not something you can live with, at least get a good quality doormat and insist that people use it and vacuum it frequently.

Just those two things can reduce what gets tracked in by more than half.

And that is something you should know.

And now that this episode is over, what you think about it matters to us.

I love to recommend a great podcast when I find one, and I found one.

It's called All the Hacks with Chris Hutchins.

And it is so good, I even had Chris on Something You Should Know as a guest recently.

Chris Hutchins is what you'd call a financial optimizer.

He has sold two companies.

He's a master of credit cards, reward points, and travel miles.

I mean, if there's a way to stretch your dollars further, he's probably already figured it out.

But the show isn't just about points and miles.

Chris dives into all kinds of smart strategies to upgrade your life.

He recently did an episode on the top 50 ways to optimize your life, money, and travel.

And he did an episode with Ben Carlson about how different generations approach wealth.

And every single episode has at least one tactic you can immediately put to work, whether it's growing your net worth, boosting your productivity, or just traveling better for less.

And what you'll notice right away when you listen is Chris does his homework.
