Why do people cry?

Not what makes them cry, but why when I cry does my breathing become erratic and why do my eyes tear? What is the purpose? Also, how do I find out if anyone else has already asked this question?

Why?

Most are Ravens and Chargers fans I think.

Don’t know, but I read somewhere that some other apes cry the way we do. Gorillas, I think it was.

You ask me. I posted a thread on this last year.

Here you are.

Tears of emotion have a different make up from those caused by irritation.
IIRC, emotional tears contain, rather than toxins, excess catacholemines.
