I recently saw a show on TV about cryogenics -- the science of freezing your brain after you die so someday, when they find the cure for whatever killed you, they can insert your brain into a new body and you can pick up where you left off. I'm not a doctor or a scientist, but it seems to me there are two big problems with this idea, even if they ever figure out how to do it. One: What body are they going to put your frozen brain into?
