“Cryonics is an experiment. So far the control group isn’t doing very well.”

— Dr. Ralph Merkle

“Why shouldn’t I eat toothpaste? It’s a free world. Why shouldn’t I chew my toenails? i happen to have trodden in some honey. Why shouldn’t I prance across central park with delicate sideways leaps? I know what your answer will be: “it isn’t done”. But it’s no earthly use just saying it isn’t done. If there’s a reason why it isn’t done, give the reason – if there’s no reason, don’t attempt to stop me doing it. All other things being equal, the mere fact that something “isn’t done” is in itself an excellent reason for doing it.”
