even though we aren't going to die and nothing is going to happen that could harm ANYTHING at all, people who actually think they are going to die kinda have no reason to be freaking out anyway:
if you believe in an afterlife everyone will be there with you + god and whoever so it'll be like nothing happened anyway
if you don't believe in an afterlife then who gives a shit you won't even know you died. it'll just happen and then nothing
