Tears suddenly start flowing out of our eyes when we find our long lost friend or when someone unexpectedly decides to break up with us. Do tears really save us from harm? Or are they just the reflex shown?
What biological purpose do tears serve for the body?
As I understand it, crying causes endorphin release, specifically leucine-enkephalin. This serves as a painkiller for us. Are tears the only way to accomplish this? It seems I am missing something because oozing out of our eyes is an inferior pain distribution system to say; the circulatory system.
