i already put myself thrue hell with alcohol and drug abuse. Sitting in a bathtub snorting cocaine naked is hell
Nothing. I already don't believe in anything like that :)
Probably the same as what it would take for you to believe in a God---the existence or non-existence of an afterlife.
Of course, then it would not be about belief, it would be about verification of previous beliefs.
(That's it---my head is starting to hurt.)
