As Ricky Gervais said, that because Atheists don't believe in an afterlife, they have everything LIVE for and nothing to DIE for. As for my molecules - I've shed countless billions of the things over the last 52 years which are still out there somewhere (matter can't be created or destroyed) but I'm not aware of a single one of them.

After life, after shave, don't hold with any of it.
