ELI5 Does crying actually serve any purpose? If so what is it?

Yep! It's a distress call - it tells everyone else around you that something is wrong and you need help (even if you don't want help). The most common thing you think of when crying is a baby, and their crying is actually designed to be different. Have you ever been on a plane or train and a baby cries and it's *extremely annoying*? It's supposed to be - their crying is biologically designed to irritate you.
