Now seeing as the human animal evolved to reproduce, evolution has no interest in what happens with the individual after reproductive abilty has been achieved

I think that this statement is just plain incorrect.  People of grandparent's age can and have contributed many things to a successful society: wisdom, child-rearing while the parents are busy with active activities, etc.  This also figures in to the "evolutionary" picture.  

Swear to God.  NOBODY would give a rat's ass about "life after death" shit and this entire topic if it weren't for your biologically programmed "fear of death".  I look forward to GETTING THE FUCK OFF THIS PLANET!  Fortunately being here is only a life sentence.

In the end, might makes right. Nothing has changed since the caveman.
