That is something I rarely ever venture into, the afterlife I mean.
If one is an optimistic athiest I would guess (using current theoritical science ans basic physics) you cannot destroy energy. Perhaps energy that is what makes us all unique and singular is transferred into one of the 11 mathematically-proven dimensions.
A pessimist, well, this is pretty much it. Live it to the fullest. Live fast, die well, and have a beautiful ending.
Me? I'll reserve that for another time.
