I find it ironic, that some have faith in cryogenics given the evidence for any possible success is certainly no better and in many ways much less then the evidence for a omnipotent creator who will resurrect your body at a future date.
I forget who said it, but there is an argument for believing in God which says "if you don't believe, and He does exist, you lose everything. If you do believe, but He does not exist, then you've lost nothing. So you might as well believe."
The problem with that, is which God should you choose to believe in? Zeus? Odin? Amun-Ra? Someone else?
The reason I bring this up, is that cryogenics is a bit like that. If you choose to be frozen, and in the future they are able to revive you, you get a second lease on life. If it turns out that they cannot revive you, it's no different than if you hadn't gotten frozen. So if you can afford it, you might as well freeze yourself. The difference here, is there is no "but which God should I believe in?" problem. At least not as far as I can tell.
