I wonder what leads people to believe that anyone in the future will be interested in applying their staggering new re-animation technologies to centuries-old frozen corpses?

There's a comment somewhere in this thread about perpetual motion. This tech seems to be its mirror-image, equal in impossibility, but opposite in aim. To stop all motion and decay, forever. Sometimes, it's wise to be circumspect, and to admit the possibility of a future technology that will change everything.

In the case of cryogenic storage of viable humans, however, I think it is straight-up, bona-fide, no-exceptions, impossible.
