Interesting, although I've always wondered what the value would be of preserving an older individual (I'm assuming s/he's on the old side). Maybe I'm simply not well-versed in medical advancements, but it seems the problem of reviving a cryonic (if that is the term) is a completely different problem from reversing the aging process, or in short, preventing death entirely. Of course, there could be large overlap with the advancements, just my two cents.
