The promise of nano-molecular robots being able to repair cellular damage, coupled with this having been declared the era of brain science, the ability to regenerate spinal tissues in other mammals, and the successful complete sequencing of the human genome are all encouraging examples of technologies rapidly approaching practical applications for the common man, and much more to the point, the applicability to treat severe trauma in medical situations. Cryonics relies upon the rational extrapolation of the power of such things to provide for the hope of revival of damaged patients in the future. So when will we be seeing such "time capsules" walking again in our midst?

The problem is that once a person is frozen the water contained in the cells of that person does what water always does when it freezes - it expands. This causes diruption of the cells and doesn't just cause death, it causes a goo to be left where there was once a viable cell.
And once a brain cell dies, it looses it's ability to hold information. Nerve tissue might be grown that is new, but it's a blank slate.
There is no way now to revive the people frozen and have their minds intact. Ask a neurologist.

Within the next 75 years we may revive dead patients but the body's thinking, feeling and reasoning skill may be on par with a person in coma. It must be remembered that the whole is much greater than the sum of the parts. Also the cold environment may not allow the proper functioning of the several bipolar feedback loops required for homeostasis.

You mean Cryogenics. And no man already alive will be able to survive in cryo-genic stasis. Our cellular walls cant handle it. But I know of a place called Brookhaven National Laboratorys in Long Island New York that is researching the genome code Of a bull-frog. In the winter this frog buries itself in the mud and freezes over, then in the spring it thaws out and is revived. Natural Cryo-stasis. It's cells are elastic enough. So if we could break down the genome and isolate the strands responsible for dictating this, we will be able to create people from an embryonic state who's cellular structure would be compatible for cryo-stasis. But as for me and you...too late.

never... I was going to say the same stuff everyone else is saying about cell damage and neuron function, but oh well...
