i think religious people could possibly be less afraid of dying, maybe coz to them there is the excitment and curiosity of an after life. i think people with no religion might be more afraid, coz they dont know what is after death for them. i dunno but im only generalising right now.. i mean, im agnostic, not religious, and im not afraid of dying at all.
another reason people might be afraid of dying, could be that theyre afraid to leave behind people they love. that would probably be the only reason i'd be a bit afraid, but it still wouldn't make me heaps scared.
