Cryogenics seems to me to be sort of the ultimate in selfishness (well, maybe not the ultimate, but right up near the top). In the (in my opinion) vain hope that someday you'll be thawed out and as good as new you use up resources, time, and people to keep your most-likely-dead carcass frozen. Just because your body is flash-frozen doesn't mean that you're not dead.

Hardy had it right when he wrote, "...for you are men, and rest eternal sorely need."
