X-Message-Number: 25877 Date: Thu, 24 Mar 2005 08:29:19 -0500 From: Thomas Donaldson <> Subject: comments on your message To Doug Skrecky: I note that deGrey is responsible for the article from GERONTOLOGY which you quoted. As you know, but others on Cryonet may not, deGrey is an open immortalist. Although the possibility he raises very well might turn out, one experiment now in progress may answer his question: the experiment on the lifespans of calorie restricted monkeys. Since monkeys live much longer than mice or rats, this experiment will take more time to show any amount of increased lifespan. I have myself wondered about the application of research on worms or fruit flies to our own human lifespans. (Even the worms are closer to us than fruit flies). Ultimately we'll simply have to see: deGrey's article was a speculation, not a statement of experimental fact. However there is one fact that every way presently proposed to deal with aging does satisfy: all of them fail to turn the lifespan curves of treated animals so that it shows only a random loss. Even calorie restriction moves the downward hump of the lifespan curve over, it does not do away with it completely. Even if some presently suggested treatment succeeded on us humans, at best it would give us more time to wait until true abolition of aging became possible. Best wishes and long long life to all, Thomas Donaldson Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=25877
