I think cloning has very little impact on the rationale for signing up for cryonic suspension, except that it strengthens a bit the argument that neurosuspension patients may be just as viable as whole-body. First of all, you don't know that you'll be alive in 10-20 years; you could get hit by a bus this afternoon. If that happens, and you haven't made cryonics arrangements, then no future developments are going to help you at all. Second of all, it will *not* be possible to attach a new body to your head in 10-20 years. If we're lucky, we may be able to repair minor damage to the spinal cord by then, but doing a whole-body transplant is a very different matter. I'm not saying "never", but I will confidently predict "not in 20 years". 50-100, perhaps. Thirdly, even if we could graft a young body onto your aged head, you would not get the vastly extended lifespan you hope for. Your head would still be old and getting older, and that's what matters. A young lower body might reduce the chance of heart attack, but it won't reduce the chance of senile dementia, brain tumors, etc. It would probably not affect maximum lifespan at all. Finally, your last point, about the possible problems with cryonics, is irrelevant. Signing up for cryonics does not cause damage, memory loss, etc. This is known with certainty. Actually being suspended, now *that* is an unknown -- but if medical breakthroughs in the future prevent you from dying in the first place, you will never be suspended (despite your precautions), and it won't matter what damage suspension might cause. If you had posed this question in response to possible reversal of aging, it would have been more interesting -- surely you're following the work with telomerase? But even then, the last point would still apply. I'm 26, and I now consider it reasonably possible that I will live to 150, by which time uploading may be developed, and I'll never need cryonics. But I'm still making my arrangements now. Cheers, -- Joe ,------------------------------------------------------------------. | Joseph J.
