Not all of what makes you you is encoded in the physical state of the brain (or whatever you would have preserved).

This is probably true, isn't it? Most of what makes you, you, is in your brain, but another large part of it is mediated by hormones going to and from the rest of your body... I think. Yet most LWers who are into cryo go the 'neuro' route. Is there some reason why this consideration is not nearly as big a deal as I think? Is the idea that making a 'spare' human body is cheap?
