1) how does our body know to release different tears for when we are crying tears of happiness or sadness? does it have something to do with endorphines being released when we are happy? like are endorphines released within the happy tears?
2) what tells our body to cry when we feel this way? why don't we sneeze or start coughing for example? why water from our eyes?
3) how old is water? where did the first drop come from?
4) why do we laugh? how does our mind distinguish something is humerous? once again, why don't we cough, or swing our arms or something?? why don't we yell?
i'm just really interested. thanks
and please answer scientifically.. not god related shit. that tells me nothing.
