What's important is the memories and impression one has left among the living. It really doesn't matter what happens to the mortal body after death. Ideally someone else could benefit from my body parts and in so one can continue living through others. That would be the best scenario.
not so much care...really funny thing is human is the only animal has to leave their bodies or something on earth even after death!!..i mean the earth if in this case, may finally full of dead person things in one day because of over population!
