My answer to (3) is "no" for rather trivial reasons, as my state 20 years ago is most comparable to someone who died and was not a cryonics patient: the thing that existed and was most similar to "me" was the DNA of people who are related to me. I don't count that as "alive", and I doubt that most people would.

Ask me (3) in the future, and I will probably have a different answer. (Wait until I'm 24, though, because I don't really identify so well with infants.)
