All the discussion of an imaginary lawsuit set up by David Pizer will be ending, and we'll have Cryonet dealing with other issues. Also a short comment for David Stodolsky: you believe that means to increase lifespan will be faster to develop than suspended animation. Certainly such means get more press and seem more popular. However instituting a new kind of medical procedure take far more time to be done in human subjects than it does in experimental animals. Whatever drugs increase lifespan, they'll have to get past the FDA (which presently doesn't even recognize that aging is a disease), and find doctors then willing to give it to their patients at a reasonable price. Not only that, but proving that a drug or treatment actually prolongs the healthy lifespan of PEOPLE will take considerable time. Even to prove that it does so in apes will take a lot of time; chimps live about half as long as we do. Sure, we can get all kinds of indirect evidence that our test drug increases lifespan, but such evidence will also require confirmation --- and because it's more indirect than simply showing that the test drug prolongs human lifespan, there's bound to be lots of argument as to whether or not that indirect evidence shows what is claimed. The essential point here revolves about the word PROOF. Most doctors don't wish to apply treatments with uncertain effects to normal patients, or to patients who aren't so far gone already that their death would otherwise be imminent. None of the antiaging drugs now known instantly rejuvenate anyone who takes them. And if we compare this situation to the present work on brain vitrification, brain vitrification looks like it will come a long time before treatments of human patients for aging are agreed on by the medical establishment. Experiments on vitrification do not take 2 years to perform (the minimum amount for a lifespan experiment on mice). Many different solutions and procedures can be tested in 2 years. You probably know of the experiment in progress on calorie restriction of monkeys: it's lasted years so far. Both cryonics and antiaging have lots of social and political opposition. If we consider not trivial increases in lifespan such as 30%, then antiaging gets just as much opposition as cryonics. But cryonics is in a much stronger position: the experiments needed to prove that we have a provable way of preserving people can be done far more quickly. That is why, despite all the noise, I think that cryonics will be shown to work before antiaging (in the nontrivial sense) ever gets far off the ground. Best wishes and long long life to all, Thomas Donaldson Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=26586
