if our cells become addicted to emotion why would they ever become addicted to sadness.
if our main goal is to survive, i dont underatand how our bodies can self destruct.
how they get diseases, we have not evolved much, not at all.

we know how to make people live longer, but not to acutally make our bodies live longer.
we can hook them up to machines, in fact most people dead today could still be techinically alive through life support. so we could just have a whole mess of the living dead.

but i guess we respect ourselves moure than that.
or maybe doctors just dont give a shit after their first person dies. then all the living and dead look the same to them.
