Is there a scientific reason for why people cry?

Question

Especially since some people believe science explains everything, without stopping to think that abolutely nothing can be proven because the human race hasn't existed long enough to really know anything, lol.

Answer 1

why does everything have to have a scientific reasoning behind it? you cry becuase of emotions, nothing scientific about it.

Answer 2

its a way to release strong emotions, they are like really fluid words that cannot be expressed through the mouth

Answer 3

There is a scientific reason. And its true that humanity actually knows nothing yet, compared to humanity's knowledge in the future.

Answer 4

I agree with Micheal that facial expressions go so far back in time that they are more or less instinct. But the ability to cry are caused by multiple reasons, I would think.  You have a point that much of science still has a way to go.  I would stop short of saying that absolutely nothing can be proven. Every discovery can lead to numerous more discoveries.  The illness that my grandfather died of is no longer a problem and an illness I suffered as a child is no longer with us.  Science accelerates at faster and faster speeds.  Always question science just like you should question your government but also you have to have some faith in it.  People assume that there were no discoveries in prehistory or dark ages but there were just they weren't written down. Today we keep better track of information and that will make a difference.

Answer 5

Yes there is. And the rest of your statement is false!

Answer 6

people cry

a) when something gets stuck in their eye, because the fluid washes debris away

b) to eliminate hormones...scientists have analyzed tears and they contain a high level of concentrated stress hormones

Answer 7

Eye contact and facial expressions  are our species dominant way of communicating..a smile can be seen from a mile away..
