This One's A Tear Jerker

By The Rest Is Science

Summary

## Key takeaways - **Humans Uniquely Cry Emotional Tears**: There's only one animal on this planet that cries emotional tears, humans; we have not seen that in other mammals or birds, though there's debate with stories like one camel. [02:14], [02:44] - **Small Moments Trigger Overwhelming Cries**: Michael cried alone watching About Schmidt over a simple drawing of a man and child holding hands, overwhelmed by its pathetic smallness yet powerful meaning; Hannah cried at her dad's eulogy recalling holding his hand as a girl. [06:02], [08:06] - **Babies Start Emotional Tears at 139 Days**: Darwin observed his baby had reflex tears at 77 days from a coat cuff but emotional weeping not until 139 days; babies first cry vocally as distress calls without tears. [17:46], [15:26] - **Crying Formula: Meaning + Vulnerability**: Crying equals meaning plus vulnerability divided by sensory threshold, where meaning is an idea's value, vulnerability your openness, and threshold your personal sensitivity limit. [10:00], [11:09] - **Hormones Lower Crying Threshold**: Androgen suppression in cancer treatment raises prolactin, making a man cry at puppy commercials; tiredness, pregnancy, and plane hypoxia also make people weep easier. [30:10], [31:08] - **Crying Signals Social Vulnerability**: Crying makes people seem sincere, warm, but also unstable or manipulative; it deescalates conflict by showing literal vulnerability with blurred vision, prompting help. [28:17], [35:12]

I found a equation. You're going to love this. All right, you ready? Crying

this. All right, you ready? Crying

equals >> Oh god.

>> meaning plus vulnerability divided by sensory threshold. How are

you measuring vulnerability? What's the

what's the unit of vulnerability that we >> It's the metric unit. One pathetic.

Don't make up equations. Not in my presence.

This episode is brought to you by Cancer Research UK.

>> Imagine this. Inside all of us, billions of cells follow millions of instructions written in microscopic code. And when a new cell grows, it copies those

instructions. But the smallest error can

instructions. But the smallest error can lead cancer to develop.

>> Right? And this is the reason why there isn't a single cure for cancer because you know there are there are more than 200 different types. Each of them have got different distinct characteristics, you know, different challenges,

different mysteries. And that means that

different mysteries. And that means that trying to cure cancer isn't like following a single path. It's like

trying to map out an entire forest.

>> That's right. And Cancer Research UK is the world's largest charitable funer of cancer research. I mean, their work

cancer research. I mean, their work spans more than 20 countries with over 4,000 scientists, doctors, and nurses pushing knowledge forward to save and improve lives worldwide. You know, over

the last 50 years, the work that this charity has done has helped to double cancer survival in the UK. And you you have to think about that is that is more parents at the dinner table, right? That

is more friends at their birthday parties. That is more people who are

parties. That is more people who are living longer, better lives.

Welcome to the rest of science with me, Hannah Fry, >> and me, Michael Stevens.

>> And we thought we would talk about crying today. Specifically, why do

crying today. Specifically, why do humans cry? Why do you cry, Michael?

humans cry? Why do you cry, Michael?

>> I don't want to get into it right now.

But I want to know why. Because there's

only one animal on this planet that cries emotional tears. Are you sure? Oh,

I know that there's some debate. There's

some stories that camels have cried in emotional moments like when they're reunited with their babies. One camel,

by the way, not camels.

>> A single camel.

>> But what what is your feeling here? Do

you think it's uniquely human to cry emotional tears? Because as we all know,

emotional tears? Because as we all know, anything with wet eyeballs is going to have tears.

>> Yeah. But we produce a bunch when we're emotional. And we have not seen that in

emotional. And we have not seen that in other mammals or birds. Cuz I mean wet eyes, there's three reasons why you have wet eyes. There's there's like the sort

wet eyes. There's there's like the sort of lubricating tears that just stop your eyeballs from turning into, you know, raisins. Um there's the reflex. If you

raisins. Um there's the reflex. If you

get something in your eye, needs to water and flush it out. And then the third one is the emotional tears, which supposedly has all kinds of hormones

inside of it, which make it chemically distinct from the previous two. And

that's the one that we're saying is >> that yeah, we just don't see it in other animals and maybe we haven't looked closely enough, but you don't have to look very close at humans to see emotional tears.

>> Yeah.

>> Weeping and sobbing. So why? Who was the first person to weep? At some point in evolution, we went from being uh homminids that didn't cry tears to

suddenly there was a first person who was like overwhelmed. Maybe it was a baby and tears came out and they were like probably freaking out. Their

parents were like, "The baby's leaking.

>> What is this?"

>> And now the tears are just a thing.

Maybe actually the distinction between not crying and crying is slightly fuzzier than you're describing because you could still have tears running down your cheek, but it's like the cause of

it, the kind of the thing that caused you to cry or caused the the tears to leak from your face. That's the thing that slowly changed over time.

>> Yeah. Okay. So, let's start there. What

was the last thing that caused you to cry?

>> Um, so my my Well, mine's mine's gonna be a bit of a downer, but my dad died this year, so uh I cried very much at his funeral. I was really good at the

his funeral. I was really good at the morning.

>> Yeah.

>> Yeah. There's a lot you just said there.

You were really good at the morning.

What do you mean by good? Like

>> I was a sight to behold.

>> I was the picture of morning >> of morning. I was

>> And that's just it. I I think and I think what we'll get here through the talk that I think it's about the picture. It's about signaling something.

picture. It's about signaling something.

>> Okay, that's so interesting.

>> Not by choice though.

>> Well, that's one thing that I think is interesting because I was giving the eulogy and uh there was a moment in the eulogy where I caught myself and I knew

that I was had the instinct to cry and was desperately trying to repress it. My

voice went high. I had the lump in my throat. like all of the kind of

throat. like all of the kind of physiological responses that you have to trying to suppress this cry. And that I think does tell you that these things aren't necessarily you you don't necessarily have agency when it comes to

crying.

>> That's right. This matters to me because I'm I think probably I shouldn't be, but I'm obsessed with figuring out what it is that describes humanity as simply as

possible. And so looking at the things

possible. And so looking at the things that differentiate us from other animals on this planet is a place to begin. And

emotional crying is one of them.

>> Oh, Michael, when did you last cry?

Hannah, I'm glad you asked because did you like my Hannah impression?

>> That was really good. It was good. I

think I'm a bit more cocky than that, but sure.

>> I Gner, wouldn't you? I don't really know English accents.

>> When did you last cry?

>> The last time I cried was very different than yours because I was completely alone. Uh, I was watching about Schmidt,

alone. Uh, I was watching about Schmidt, right? And I guess this is a spoiler,

right? And I guess this is a spoiler, but I'm going to say it anyway because you can go and find your own sad movie.

But at the end, this child that he has been uh that he adopted, the main character, Schmidt, uh he gets a drawing from the child. And it's a drawing of

him and the child holding hands.

>> And I just got so wet in my eyes. I

didn't like um sob. It was a quiet cry, but I was just so overwhelmed at the sort of patheticness of how small this

event was and yet how powerful and how much meaning it had. Was it that you were overwhelmed by the emotion of the of the scene in the film? Or was it that

it was tapping into something that you felt about your own family, your own, you know, your own child, your own experience?

>> I don't know. I didn't even have a child at this point.

>> Oh, wait. Hang on. How your child's like many years old.

>> Look, >> is that a lot? I want Have you cried this decade?

>> All right, you got me. I cried more recently. I'll just I don't I don't want

recently. I'll just I don't I don't want this to become a political discussion, but I cried after watching a politician speak. And the politician said something

speak. And the politician said something that was just so humble.

>> Yeah. I also when I need a good cry, I do uh late at night turn on military funerals.

>> Yeah.

>> The circumstance and pump of these ceremonies with the other soldiers there doing the 21 gun salute who may have not even known the deceased. The flyover in

with the empty man formation. It's just

so big. the the funeral procession going down the freeway and just people have come out onto the street just so their kids can see to see what it's so

human.

>> It's so weak and humble but yet so significant at the same time.

>> It's like the bigness and the smallest of the entire world in one thing. the

specific moment that triggered me when I was speaking in my dad's eulogy. I'd

written this eulogy and I'd talked about all the funny things that we've done together, these amazing things, and I'd written that I remembered the feeling of holding his hand when I was a young girl. And that was the thing that got

girl. And that was the thing that got me. It was that connection of knowing

me. It was that connection of knowing that I'd held his hand that morning when he was in the casket and then that that very visceral sensation of being a child and looking down at your dad's hands

when they're covered in dirt from work.

And I think that's it. It's like it's it's it's the bigness and smallness simultaneously of those moments that can be overwhelming, >> isn't it? Yeah. I saw my father's body

as well. They had a room that his body

as well. They had a room that his body was in and they said, "Yeah, well, you guys can go and and you know, say last things to him." And it didn't really hit

me until that moment when they asked me to go first that I was like his son. It

was like, really? Yeah. See, and this is starting to make me feel >> Yeah. Yeah.

>> Yeah. Yeah.

>> Like my eyes have a little bit more fluid in them.

>> Yeah.

>> But it's not because you're here or these people are here because I've cried mainly alone. I'm always alone in I've

mainly alone. I'm always alone in I've been alone in those circumstances and yet I still did this.

>> Still got watery eyed.

>> It is strange, isn't it? It is strange the things that trigger you.

>> But it's also not strange. Like these

stories all make complete sense, right?

No one's going to go, "You cried when you watched a funeral." But to put it in the context of no other animal has been definitively observed crying emotional

tears, that's when I think we need to say what are humans up to? I'm still

feeling very emotional. I want to I want I want to now just shift to something that I think will make you cry for a very different reason. All right. As I

was looking into theories of emotional tears, I found a equation, >> right, >> out of some research from Alabama. And I

think h you're gonna love this. All

right, you ready?

Here's the equation. Crying equals

>> Oh, god.

>> meaning plus vulnerability divided by sensory threshold.

>> Okay, this is one of the fake equations that exist in the world.

>> I knew you'd call. I've got to be honest with you. I have a severe allergic

with you. I have a severe allergic reaction to them. Tell me why. They make

me actively angry. There's a multitude of reasons. For one thing, um, how are

of reasons. For one thing, um, how are you measuring vulnerability? What's the

What's the unit of vulnerability that we're >> It's the metric unit. One pathetic.

>> Well, I don't know, but I see. Yeah, I

see. I agree with you.

>> Okay. Also, what was it? Sensory

threshold. Did you say? Okay. So, what

happens when your sensory threshold is zero? That means you're infinitely

zero? That means you're infinitely crying.

>> Ooh, yeah. The space-time continuum is destroyed by your crying.

>> Or what about if you've got a very high threshold crying? I mean, what about if

threshold crying? I mean, what about if you've got a negative sensory threshold?

You go to negative crying.

>> Negative crying. You suck moisture into your eyeballs.

>> Absorbing water from your eye.

>> You need to stop negatively crying. I'm

drying up over here.

>> Also, meaning sorry, what is the meaning of meaning?

>> Mhm.

>> I think I'm not saying that there's, you know, there's some some ideas behind that, right? It's like the value of an

that, right? It's like the value of an idea to you, how vulnerable you're feeling, >> you know, your own personal threshold.

But this is like >> I mean, putting it into an equation gives it this false sense of precision, which is false of precision and correctness. I think what's being said

correctness. I think what's being said here is that there's something >> called meaning and there's something called our vulnerability to it.

>> But then it's all mediated by just how where our threshold is for crying. the

lower it is, the bigger that ratio gets and the more crying there is. But yeah,

you're right. These are such soft terms. >> I'm okay with that idea. What you've

just described is I think that's I think that's good. I mean, every the two

that's good. I mean, every the two situations that we've described about us crying definitely fit into that category, right? But also this idea of

category, right? But also this idea of the the threshold that you as an individual have that some people are more sensitive to crying than others. I

think I'm okay with that broadly as a rough idea. I think that's that's that's

rough idea. I think that's that's that's good. It's just don't make up equations.

good. It's just don't make up equations.

>> Yeah.

>> Not in my presence. Uh so then let's let's look at the the data. Let's look

at how crying begins in in the life stages of a human >> in a baby.

>> In a baby.

>> Yeah.

>> Okay. They're famous criers.

>> They're Yes. They are mega criers. I

mean the thing is that crying in babies there's there's different versions of this, right? Because there's the crying

this, right? Because there's the crying as a sound for different reasons. So

whether they're hungry, whether they're uncomfortable, whether they've got gas, whatever it might be. But that there's a really clear evolutionary purpose for that which is in order to signal for

attention to the carer to sort of fix a situation >> right to get nurturing to get attention.

It's a distress call and you're right, we see this in all kinds of animals.

>> Absolutely. There is some work, I don't know whether you've come across this.

This is by a nurse called Priscilla Dunston >> and uh she has a theory, right, that uh there's actually the different reasons

why babies cry uh changes the sound that they make purely because there is some reflex that starts the sound. So for

instance, when a baby is hungry like and we're talking really really young here, right? like first first three months of

right? like first first three months of life. Uh when they would be suckling,

life. Uh when they would be suckling, they uh the tongue in the mouth goes into a certain position that makes a like sound. Or there's a few others.

like sound. Or there's a few others.

There's like a if they're really uncomfortable from trapped wind, it makes more of a like e sound or there's like a you know ones beginning with a more of a h sound, that kind of thing.

Now I should tell you that there have been like some smallcale studies on this and it's really difficult to definitively pin down that this is what babies are doing but there are lots of

parents who say that this is actually a really useful rule of thumb rather than a a hard and fast scientific rule.

>> You can kind of figure out what the baby is trying to say more specifically than just look at me give me attention.

>> Exactly. Exactly. Right.

>> Okay. That's making me think. I don't

know if you know the answer to this, but when a child is extremely young, still breastfeeding, the sound of its tears can cause the milk to >> Does that depend on how the cry sounds

is what I'm asking.

>> It's It actually makes makes your boobs hurt.

>> Yeah.

>> Like it's unbelievable.

>> Any cry or is there does the hunger cry cause it more?

>> Well, it's specifically your baby as well.

>> Only your baby. So, so the thing is that the the hormone that that creates let down that that essentially allows the milk to to to run. There are a few different ways that it can be signaled

and one of them is an auditory cue and within 48 hours of your baby being born, your body essentially learns your baby's cry and it triggers the production and

let down of milk when it hears that that signal. And I think it is, I'm talking

signal. And I think it is, I'm talking personal experience now rather than uh rather than >> sure understand >> rather than scientific stuff, but I think I think it is specifically cry because there's a different cry when your baby is hurt,

>> right?

>> And and that doesn't signal the milk.

>> And these all sound like really deep evolutionary mechanisms. But what these two-day old babies don't do is cry with emotional tears.

>> They're not watching military funerals.

>> They aren't. They're crying by creating a vocalization, but they're dry on the face.

>> They are.

>> Now, I've I've read that it's around four to eight weeks of age that they might you might start to see tears, >> physical tears, but are they emotional tears at that stage? You know, Darwin, um I don't know if you've heard met him

a few times.

>> He's kind of a big deal. Yeah.

>> Um he wrote this book. It's uh you know as well as the origin of species and um descent of man and Harry Potter and the Chamber of Secrets it's important books.

He also wrote this book which is called the expression of emotions in man and animals. And this is it's a stalking

animals. And this is it's a stalking read Michael. I would thoroughly

read Michael. I would thoroughly recommend it to anyone. He's got an entire chapter on blushing. He's got an entire chapter on weeping. Um he goes around just observing all kinds of animals and all kinds of humans in all

kinds of situations. He's got a sweaty hippo who's very cross in labor. Been

there. Um he's got an impatient horse.

He's got an orangutang who desperately wants some apple. It's like there's it's it's honestly it's absolutely delightful. But he also this is I think

delightful. But he also this is I think the first book to have ever included printed photographs inside of it. And uh

he has within it a study of um upset babies.

>> Oh my goodness.

>> Isn't that amazing? So, what you have here is a page of six images of very upset children.

>> Yes. And they look like they're like Victorian age children with the they're black and white photos. The kids look like they're in distress.

>> Yeah. I mean, I think that they Well, one's in a sort of high chair. They're

all wearing like really cute Victorian clothes. They're all very chubby.

clothes. They're all very chubby.

They're all just absolutely gorgeous little kids, but they're all crying >> and they've got faces that are immediately recognizable as crying. The

eyes are are closed quite shut and the the grimaces on the face. It's they're

very sad.

>> It's it they're very cute and and as normal children are when they're upset, but but Darwin uh made a study I mean both of which muscles were being contracted in their faces as they were

crying. But he also made a study of his

crying. But he also made a study of his own infants. And uh he noted that one of

own infants. And uh he noted that one of his children, one of his his babies, um at 77 days old, he accidentally brushed the cuff of his coat across their open eye.

>> Oo.

>> Accidentally.

>> Yeah. He says um and that caused tears to stream down their face.

>> Okay. At 77 days.

>> 77 days. But he was pretty sure that they weren't crying emotional tears. It

was reflex. It wasn't until 139 days that he felt that they were weeping emotional tears.

>> Okay. So, it took 139 days for Darwin's child to finally start shedding emotional tears. What is that? 4.56986

emotional tears. What is that? 4.56986

months.

>> Yeah.

>> Wow.

>> Yeah. I mean, 200,160 minutes if you like.

>> If you're rounding, if you want that.

Now, a theory I've heard about that transition, >> which to me feels like a kind of metamorphosis from not Yeah.

>> is that at first this distress call, just like you'll find in birds and other mammals, >> gets the attention that you need for all kinds of reasons. Just to get it to stop because it's annoying. Um, to get it to

stop because it could alert predators of your position. M uh but also maybe just

your position. M uh but also maybe just an a reflex like the milk let down going oh my body my DNA tells me what to do here but also uh that danger the danger

of alerting predators to where you are and aggravating the parents eventually needs to disappear. But the helplessness and the need for care never does in our

species because we have such extended adolescence pretty much our whole lives.

I think we're always childlike in ways that no other animal is >> in the sense that we play for example >> in the sense that we play in the sense that we're always like learning new things and always can learn new things.

So instead of making a racket a vocal racket when when we want to signal this >> we can do it with >> the way our face looks and with tears coming out of our eyes >> a physical signal rather than an audiary

one.

>> That's right. So, okay, interesting idea. But then, I don't know if you've

idea. But then, I don't know if you've ever met a 2-year-old. They are very noisy.

>> Yeah.

>> And they cry very loudly.

>> Yeah.

>> So, what's that about?

>> Well, okay. Yeah. Right. How I guess they're not done with the the metamorphosis yet. They're still in

metamorphosis yet. They're still in their cocoon jelling into a tear crier and not so much of a loud sober whaler.

>> Sure. But then also, I mean, there's sort of like loud sobbing, wailing that you get from a young child, >> which is genuinely, I'm hurt, I'm in

pain, or I'm hungry, I'm tired, I need something, and I can't quite articulate what it might be. That is different from watching military funerals.

>> Yeah, it is. It's certainly different that a child will cry when they physically hurt themselves, when they fall over. But I don't I will cry when I

fall over. But I don't I will cry when I hear a speech, but if I broke my arm, I probably wouldn't cry. I would not feel good.

>> Oh, I would. My lip would be so stiff.

>> You guys would be like, >> "Excuse me, I'm the British one here.

Thank you very much." Yeah,

>> I know. But I'm just saying you've got competition. No, but you see what where

competition. No, but you see what where I'm going getting with this. Like as we age, the things that make us cry are very different than the things that made us cry when we were even more helpless

and and helpless in a different way.

When you're hungry, you don't always cry the way you did when you were two or one or less.

>> Agree. Agree.

>> And yeah, I don't think anyone's saying that babies are going to watch a funeral and be able to understand and feel overwhelmed. They might be overwhelmed

overwhelmed. They might be overwhelmed just because the sensations.

>> I mean, about Schmidt is 12 plus.

They're not even allowed. They're not

even allowed. They should not be watching it.

>> Okay. So, there's definitely lots of evidence of other animals crying for pain or crying for hunger, all of that kind of thing. I think that there is evidence of other animals making

auditory and like behavioral cues in an emotional way. So, elephants is the

emotional way. So, elephants is the classic example here. Um, lots of people have reported that they've seen elephants uh engaging in mourning behavior. There's um there's one

behavior. There's um there's one particular incredible story about um an experiment that went wrong. Uh so I don't know if you know this, but but elephants have names that they give each

other.

>> How do they how do they >> they rumble? They like it's an auditory thing. They use their trunks to kind of

thing. They use their trunks to kind of call out names. It looks like elephants actually have a vocabulary of lots of different words. They have a word for

different words. They have a word for bees. They have a word for human. They

bees. They have a word for human. They

have a word for bad human. There's like

a lot actually quite a lot of complexity to animal language. Anyway, what you can do is you can turn up with a truck and a loudspeaker and play out a recording of

an elephant calling another elephant's name. And if that elephant is within

name. And if that elephant is within that herd, just that one elephant will turn around. So you'll be like Billy and

turn around. So you'll be like Billy and the elephant would be like, "Yes." Wow.

>> Which is amazing.

>> That is really amazing.

>> You have to be really really careful when you do this experiment. It's called

a playback experiment. And the reason why is that a group of researchers went out into the savannah, played a sound of an elephant shouting another elephant's name. But what they hadn't realized was

name. But what they hadn't realized was that the elephant they'd recorded had since died.

>> Oh no.

>> And so the herd who she used to belong to suddenly got extremely distressed at hearing this voice effectively from the past.

>> From a ghost >> from a ghost. and her daughter, the the deceased elephant's daughter in particular, was going through the bush like for days and days and days looking for her lost mother.

>> Gosh.

>> So, so this kind of idea of like mourning behavior that you see in animals, uh, we know that it exists not just in an observational way, but in those kind of slightly unfortunate

situations where it's actually been an outside intervention, a human intervention that has created this this morning behavior. You get this with

morning behavior. You get this with whales, too, right? like whales will will will uh carry the carcass of their dead children often for for days.

They'll form a hub around a whale that's dying. Um you know there's there's lots

dying. Um you know there's there's lots of like extremely complex mourning behavior that you see in animals. And

over the years, we've had lots and lots of reports of people who've worked closely with elephants, people, fishermen who have worked closely alongside whales who claim that they

have seen emotional tears in these situations >> really.

>> But it's just really difficult to prove, right? It's really difficult to prove.

right? It's really difficult to prove.

How do you know that it's not dust that's got in the eye? How do you know?

I mean, it's a whale for goodness sake.

It's in the water. But also, if you decided to do an observational study of a human, right, you could follow you around since 2020 and have very little evidence of you crying at >> crying. Yeah, that's true.

>> crying. Yeah, that's true.

>> It's a really rare event.

>> That's true. So, I I'm willing to admit that we don't know conclusively that only humans cry emotional tears, >> but we don't have any hard evidence that that any other animals do.

>> We don't have hard evidence. And like

personally, I think that these other animals, who knows what they're feeling, but I'd like to believe, and I think we almost have an obligation to believe that they're feeling things quite deeply. They're expressing it

deeply. They're expressing it differently, though. They're not

differently, though. They're not contorting up their facial muscles in a way that creates this redness, this puffiness, this wetness that is almost

hard to hide. Mhm.

>> Maybe they're doing something that we can't quite pick up on, but their other con specifics immediately go, they're crying. And that, I think, gets us to

crying. And that, I think, gets us to what a crying person causes us to think about them, which maybe we should do after a break.

All right, welcome back. We are talking about crying and I want to move on to whether or not crying is a choice. How

much voluntary control do we have over our emotional tears?

>> I mean sometimes none at all, right? I

mean I don't know. Have you given that you've only cried once a century?

>> No. Come on. I cry

I cry just the right amount.

>> Just the right amount.

>> Yeah. Um, but definitely I've had this experience numerous times where you get that that feeling in your throat, the lump in your throat. And and what that is is there's a competition in your throat, right, for what the muscle

should be doing. Part of you, your reflex is to help you breathe, and the other part of you is your reflex is to try and suppress the the cry. And so

what you end up with is this tension in your muscle that feels like a lump in your throat. But also what happens is

your throat. But also what happens is when you've got this tension, you lose the fine motor control that your throat normally has, which is why your voice starts to get really squeaky. Wow. Yeah.

That's fascinating, >> isn't it? The fact that we even are concerned about uh should I allow this to happen or try to resist it says so

much about the cultural and psychological importance of crying and what it means to us. The thing is we suppress a lot of emotions. We'll

suppress laughter because it's inappropriate to laugh right now. We

will be really tired but try to look really alive.

>> That's what I'm doing right now.

>> Right.

>> Boy, I could tell you some stories about how I feel right now. But I choose not to because it's all about the image.

It's all about the look. Right.

>> Absolutely.

>> And so what do sad people look like?

I'll tell you. According to some research I was reading, people look at criers as being more sincere and honest, >> warmer, >> friendlier,

>> friendlier.

>> But also probably more emotionally unstable, >> possibly incompetent, >> and also possibly manipulative.

>> Wow.

>> Okay, some of these are opposites here.

You're more sincere and honest if I see you crying.

Or maybe you're just really manipulative, right? It says a lot of

manipulative, right? It says a lot of both good and bad things, positive and negative. It's a big indicator of stuff.

negative. It's a big indicator of stuff.

And whether you think someone's tears make them seem more honest or less honest depends a lot on the context, who the person is, whether you know them or

not, it's a major signal that can mean a lot. It can be arousing. It can be soothing

arousing. It can be soothing >> to the crier and to others watching.

that point about whether or not you're choosing to cry. I don't know. I've

definitely had the experience numerous times in my life where I really haven't been able to control the fact that I was feeling like super emotional. There was

once I was in a meeting. I just uh just been appointed to faculty at university.

I was in a very important meeting and I'd been very very stressed. I was very tired. I think I was possibly also

tired. I think I was possibly also pregnant um or at the very least had a very young baby. And uh the meeting progressed, something happened in the meeting and I just immediately burst into tears and it was International

Women's Day as well. Can you imagine?

And I knew that my colleagues were losing respect for me in that moment.

But I just couldn't do anything about it. Couldn't do anything about it. But

it. Couldn't do anything about it. But

the thing is is that I do think that the there's lots of evidence that the hormones that you have in your body change how likely you are to cry. So I

have a very good friend who um has testicular cancer. He's taking some

testicular cancer. He's taking some hormones to as part of his treatment that that suppress the androgens in his body. Androgens is a is I mean people

body. Androgens is a is I mean people call them male and female hormones. It's

rubbish way to think of it because everybody has both. Yeah.

>> But um what happens as you suppress the androgen in your body, >> your uh the presence of prolactin can increase. Now prolactin is the hormone

increase. Now prolactin is the hormone that your body uh creates when it comes to breastfeeding.

>> Prolactin.

>> Prolactin. Exactly. Anyway, so he said that like during his treatment, everything's broadly been fine. He's

taking these hormones. He kind of feels normal except that he's really emotional and he cries all the time now. Like

he'll watch, you know, like a puppy commercial or something and like there'll be a puppy on the screen and he'll just start crying. And and I do think that the threshold, you don't necessarily have control over where that threshold is.

>> That's right. So hormones affect that threshold. And in your story, too, being

threshold. And in your story, too, being tired >> affects it a lot. And that brings up a thing I' I've noticed before, like it sounds true to me, which is that people are more likely to cry watching movies

on airplanes.

>> Oh, right.

>> Which I think it's one, maybe you're more tired, but also you're captive.

>> Mhm.

>> Okay. You can't shift your attention to other things because you've just got that seat front in front of you. I don't

know. You're just kind of like more alone.

>> There's like more social anonymity as well there, right? Like, you know, if you're especially if you're tucked into tucked into a window seat, >> right?

>> Like, I think you can sort of get away with crying and no one's seeing you, >> you can get away with it. Yeah. There's

less of a a feeling of, "Oh, hold on.

This is an inappropriate time to do it.

It's an appropriate time. You You don't have any meetings. You're not in a meeting. You're just waiting." And so,

meeting. You're just waiting." And so, the tears flow.

>> I also wonder whether there's something to do with the amount of oxygen that you have because I mean, when you're in the air, it's basically like mild hypoxia.

like mild oxygen starvation which I think completely changes your ability to handle stress you know lowers your mood makes you more vulnerable to about schmidt yeah I watch I watched this alone in my

apartment in New York that's all it took for me >> is it a very high apartment though are you >> it was on the top floor actually um and I felt better afterwards which like is a

very famous well-known thing about crying just having a good cry yeah >> and I'm I I think there's a lot going on there but we have found oxytocin being released, endorphins being released

because of crying. So

there's a reward for crying.

>> Some evidence that you physically feel better afterwards.

>> Correct.

>> You know, in Japan, um, this sort of trend started where hotels would have crying rooms. >> Oh, really?

>> Where you could go and watch a sad movie and just enjoy a good old cry.

>> Oh, so it was full of things that would make you cry if you needed to just have that release. Exactly.

that release. Exactly.

>> And that gets to what I'm saying about how people can be soothed by their own crying. Absolutely.

crying. Absolutely.

>> But crying can also be arousing. It can

it can make your your heart rate go up, but it can also make it go down.

>> Definitely.

>> In my experience, I've only ever felt better after crying. I've only ever felt better while crying. I'm glad to be doing it.

>> A good cry.

>> I'm not I'm sure you can feel aroused while crying.

>> Not that kind of aroused.

>> Michael, whatever. Whatever you enjoy is absolutely fine by me. I think that's you do you.

>> Well, one of the reasons why people think that uh crying makes you feel better is because of the hormones that are contained within your tears >> within the tears. So, you're they're leaving your body.

>> Yeah. So, and corticotropic hormones.

>> I've heard that before. It's like a really easy answer to like, oh, tears are great because they get rid of these hormones leaving you feeling better. And

I guess I believe that, but I think hormones are not in the tears.

Psychologically, something still happens when you've had that release. A lot of crying comes from I I believe like

evolutionarily the deep cry for help.

>> In fact, we've seen like children will cry if they get hurt and no one's around and as soon as someone arrives, they already start to feel better. This

happens to adults as well. You're no

longer in the mode of help me, help me.

You're being helped. The distress call can go away.

>> Well, Darwin was thinking a lot about the evolution of this. And uh Darwin's conclusion, you know, looking at different animals and their sort of emotions and but also in humans and

children and weeping and so on. His

conclusion really was that uh he thought this was something that humans practiced and could suppress, right? So different

cultures had different attitudes towards crying. But he also thought that this

crying. But he also thought that this was just like some kind of adaptation that doesn't really do anything, you know, like sneezing when you look at a bright light.

>> His his his idea was that it's like, okay, it's just sort of something. It's

just a kind of something. And actually,

there are some people who say this is actually maladaptive, right? Because

your eyes are filling with tears. You're

scrunching up your face. You can't see as well as you were able to before, >> right? So, so crying as a sign of

>> right? So, so crying as a sign of vulnerability is literal. When you're

crying, you are more more vulnerable.

Your vision is compromised. You really

do need other people's help.

>> Definitely. When you're around somebody else who's crying, I think that uh seeing their vulnerability sort of makes you want to appease them more. It's quite a good conflict

more. It's quite a good conflict deescalator. Crying. It certainly

deescalator. Crying. It certainly

communicates because it's possible for people to be revolted by a crying person if they don't know the person. If it

would be really awkward, they'll avoid the person. Either way, whether a

the person. Either way, whether a crier's tears make people come to them or flee them, it's a huge social signal.

>> It is a huge social signal >> and it may have maybe Darwin was right in terms of its very early emergence because we can also uh produce excess

tears just when we yawn. like the

stretching of the muscles around the eyes can cause the tear glands to put out more fluid.

>> I think a lot about how I mean humans in terms of our niche, right? We're these

like very intelligent, very social creatures.

>> Yeah.

>> And I think once it comes down to it, maybe the the sort of the the beginning of crying, maybe the first human who cried was it was just it didn't really mean anything. But I think what it's

mean anything. But I think what it's come to mean is something that's that's both of those things, both very social and intellectual. No.

and intellectual. No.

>> Yeah, I think so. I think that that cognitive social niche is where we belong. And so it's just so human to do

belong. And so it's just so human to do a podcast about crying. Let's let's have a good talk about crying, but let's also overthink it.

Let's do some cognition and let's do some emoting and some socializing, >> which in other animals isn't the key to their survival. It's not the niche that

their survival. It's not the niche that they've worked out. Ours is very much about communing with others. We're not

quite like honeybees or ants. They're

almost like a super organism in ways that that human societies aren't. yet.

Yeah, we we do a lot of other things which I don't know if animals do this, but when you know you're at a restaurant and uh the server brings you your food and says, "Enjoy your meal." And you go,

"Oh, you too." I mean, thanks.

>> Right.

>> Have a good flight. Thank you. You damn

it.

>> The way we'll automatically respond to things like, "Oh, hey, how you doing?"

"Fine. How are you?" You know, and we don't answer the question literally.

That's all there's a name for that. It's

called fhatic communion. love it.

>> Fhaticic means language. Communion means

coming together. And these these ways that we just unconsciously respond to each other just kind of signal that like, hey, I'm a human, too. I get it.

There's social rules. I'm here. I'm

available. Whatever. And I think that crying probably falls into that category a little bit. That it's a way of showing we do need each other, but in a way,

humans don't need each other. Like an

ant on its own cannot survive >> because it it it only has one role, but it needs all the different roles in its in its community.

>> Can humans survive on their own? I mean,

like really really on their own. You'd

have to be very very off-rid in order to not have any reliance on other I'm thinking about the food chain here. I'm

thinking about like I don't know the everything you buy like you sort of need other humans at some point.

>> Yeah. Yeah. No, it's a great question.

I've looked a lot into like hermits and it's almost always not totally independent. They would raid cabins

independent. They would raid cabins nearby for supplies and stuff.

>> So, I mean, I think the best example is Swana Maria, which wasn't even her real name. She was christened that after

name. She was christened that after death, >> but she was a a native on one of the Channel Islands. I mean, the ones off

Channel Islands. I mean, the ones off the coast of Alto, California.

>> I thought this was too exotic for for the English Channel >> specifically. She uh lived on San

>> specifically. She uh lived on San Nichols Island. Her people were called

Nichols Island. Her people were called the Nickeloeno people and she was the last speaker of their language.

>> Um I don't know the full history of the island, but there was like a Russian-American company that came in and they like massacred the indigenous

people off of some rumors that there had been some violence against themselves and whatever. And then eventually I

and whatever. And then eventually I think some of the missionaries said, "Let's get them all off this island for one reason or another." But they neglected to bring Wana Maria. And

there's all kinds of apocryphal stories about did she uh get left behind because bad weather meant the ship just said leave her or did she jump off the ship and swim back to the island?

>> Wow.

>> Well, all we know is that she remained there from 1835 to 1853 all by herself.

>> So for most of her late 20s and 30s, she was on this island all alone. She

fashioned her clothes out of feathers.

>> I mean, you wouldn't bother, really, would you?

>> She did bother, though. Isn't that

interesting?

>> Yeah.

>> Yeah. There's a rumor that her her feather skirt was sent to the Vatican, but then lost um after she was found, of course, because people knew she was still there. So, I guess there might be

still there. So, I guess there might be some truth to the story that she was left behind or escaped, right?

>> They knew she was there all alone and she just lived on her own. She caught

seals. She made herself a tent and may have also lived in a cave nearby. when

she was picked up, uh, she was really excited to be back around people. There

were like three or four people in Santa Barbara in a mission there who still spoke her language that she was able to speak to. Some of her songs were

speak to. Some of her songs were recorded on wax cylinders.

>> No.

>> And we still have them. None of it's been translated.

>> There are all these words that she said.

We don't know what they mean.

>> Oh, that's so cool.

>> Now, she was I I kind of believe this part of it. I think she was really excited to be back around humans and she was apparently really excited to be eating fruits and corn and all the stuff she didn't have on the island, but she

got dysentery >> just a few weeks after being rescued and died.

>> Oh, no way.

>> Yeah.

>> And she wouldn't she wasn't that old, right? Like

right? Like >> No, she Well, she was she by then she was probably like 40 41 42.

>> Yeah. But she survived for a very long time on her own. So, you know the old like, oh, you could only live a few months without food, a few days without

water, but not a second without hope.

Maybe. I've never heard that before, but I'm putting on a t-shirt immediately.

>> Please do. I guess she doesn't have much to tell us about that cuz she may have retained hope, but she certainly lived without other people.

>> I wonder whether she cried in that time.

I know cuz on the one hand, you know, she's got total social anonymity, >> right? Also quite a lot to cry about.

>> right? Also quite a lot to cry about.

>> Yeah, right.

>> But on the other hand, no one to socially cue. I mean, because we know so

socially cue. I mean, because we know so little about her, maybe she like cried tears of joy. Maybe she jumped off that ship and said, "Finally, the island all to myself. All that blubber."

to myself. All that blubber."

But probably not. I think I think that Yeah, we are a social species. So her

story makes me wonder about the social niche of humans because no one ever seems content to say, "Well, we're the thinking ape or whatever." I guess we are literally called homo sapiens, the

wise ape. But

wise ape. But >> the social aspect of it, I think, is ex is is kind of explained through tears.

What is its social role? Now that we've talked so much about it, how are you feeling about it?

>> I think it is I think you're right. I

mean look this is definitely one of those questions which is about what's the reason for this evolutionary trait right and it's like actually sometimes sometimes there isn't an answer and often the answer is we don't know for

sure so this is definitely in that category right we cannot be absolutely sure but I think that there's something in the idea of when you need to

communicate vulnerability or when your body chooses to communicate vulnerability on your behalf and this idea of like uh just bringing down the

kind of deescalating conflict, wanting to appease each other. I think it's ultimately about connection.

>> Yeah.

>> And we're connected to you, dear listener. That's How's that for an

listener. That's How's that for an ending? Do you like that?

ending? Do you like that?

>> Uh it's going to make me cry.
