All of your answers are fine and adequate, but they fail to elaborate on the real problem with life and death. They negate each other, they are mutually exclusive. As soon as you've settled down and gotten comfy with one, things up and change. You just can't do both at once and that makes for a shocking transition. Hey I'm alive! ZOT! Crap I'm dead BAMF! Damn, now I'm alive again. When will this roller coaster ever end!
