- The first thing you did in this world was cry.

What does it say about the human condition

the baby's emotionally devastated to be here, check.

Imagine asking a kid what their favorite animal was

I'd be like, okay, this kid, he's got issues.

You on the other hand could produce tears from a loss,

joy, self-pity, laughter or when the tone switches

And tis wild, but the chemical makeup of your tears

Tears of endogenous depression are different

If you remove the tears from crying people's faces,

it's hard for you to tell if they're crying from sadness

Scientists have a hard time studying tears,

A lot of these studies involve humans as lab rats,

watching sad movies and studying their crying behavior.

For example, the one on brain dead people,

could you twist that brain dead person's nipple, please?

I did not twist those nipples a scientist did.

Oh, they opened their eyes slightly, fascinating.

we know a lot more about why we emotionally cry.

Back in 17th century America for example,

it was thought that a marriage was doomed

if the bride did not profusely weep at the wedding.

This was to prove the bride wasn't a witch,

Therefore obviously the bride was crying from both eyes

it meant that the bride was not working with Satan.

Think of all the groomzillas who were like,

honestly straight weddings are like, so over the top.

to when your ancestors evolved out of the water.

amphibian arthropod millipede sort of thing, maybe.

And by leaving the water to live on land,

all of these land dwelling animals from then on

needed a lacrimal apparatus to produce tears

The first is basal tears, which is made up of three layers.

that stops the other layers from evaporating

and keeps the surface of the eyes smooth.

which is unique to all land dwelling animals.

In fact, all animals, except for snakes and amphibians,

that consists of nerve endings in the eye

that when stimulated by mechanical, thermal, chemical,

It should be known that you don't have a storage of tears

in your eye, ready to come out when you cry,

the tears are created due to a sensory in your body

Humans, that means me, that means you are special.

We are the only animals with emotional tears,

Which are controlled by the prefrontal cortex

and the anterior portion of the limbic lobe of the brain.

crying was the only way that we were able

As babies, we don't have the words to express our feelings,
