The real point in all of this is that I don't know the procedure to repair a
frozen body. I can imagine a similar 19th century conversation about
building a supersonic airplane. Although engineers of the time could have
come up with reasonable educated guess about such a machine, they would also
have been wrong about a great many things and would not have been able to
come up with a viable design in any case. We are now in the same position
concerning the reanimation of a cryonically suspended patient. And just like
our 19th century predecessors, we must await future engineering work to
solve the problem. That's ok, time is not much of a factor when you are
frozen in liquid nitrogen.
