Here is a link to a thread at a forum for skeptics -- the JREF forum. This particular thread fairly quickly evolves into a discussion of cryonics, with some posters arguing that restoration of a person from cryonic suspension is impossible in principle. A poster named Dancing David seems to take this position and discusses in particular the question of the restoration of memories. He says that people who "freeze their heads" are wasting their money.
