Tears.

Did you know that tears shed over movies contain 25% more protein than tears shed over onions?
Well, it is true.

Crying is, actually, a very fascinating thing. When you think about it, we don't really know a lot about it. It means different things to different people (and in different cultures), but, for example, every culture in the world is known to cry in funerals. Except in Bali, where people are 'allow' themselves to cry only two full years after the funeral. Tears are not JUST water, they contain also mucin, oils and proteins, some antibacterial, immunoglobins, glucose, urea and some salts. Phew...who knew?

So, next time you cry, think about it, it might not be as straight forward as you think. And apparently they DO respond to our emotions...interesting indeed.
