I'd say in your sleep. That way the rid yourself of the anxeity and terror awaiting to be pulverized by a bomb would induce.
Well unless you get hit unexpectedly, but still. It's a horribly violent way to go. Phisically painless, maybe, cause there've been atomic bomb survivors, but the psychological impact would be just unbearable for some.

Death, can be an hour long process, when you're psychically shut down, but have a chance to recover. I don't believe this hurts because your brainwaves aren't forming thoughts and pain, which is an evolutionary necessity to let one know if he/she is hurt, so your brain can't form the thought of pain. So, no pain.
Whether dying hurts is a matter of how you die, I would think. Suffocating to death vs. a bullet to the brain comes to mind. What's interesting to me is the surge of adrenaline and other physical reactions from your body when you think you're going to die. Ask someone who has had a NDE to explain the crazy feeling you experience when you realize that you are going to die.
