X-Message-Number: 24321 From: Date: Sat, 3 Jul 2004 10:30:12 EDT Subject: Hayflick If the quotation below is complete and accurate, it appears that Leonard Hayflick is suffering from senile dementia. 1. A categorical statement that it is impossible to slow, stop, or reverse human aging. (This is a claim of ominscience.) 2. >Most of the resources available >under the rubric "aging research" are not used for that purpose at all, >thus making the likelihood of intervention in the process even more >remote. Here he contradicts himself by implying that intervention is only remote, not impossible. 3. >why is the study of aging virtually neglected? Neglected? The literature is voluminous and growing rapidly. And from his point of view, why should it matter, if it is hopeless anyway? 4. >When it becomes possible to slow, stop, or >reverse the aging process in the simpler molecules that compose inanimate >objects, such as machines, then that prospect may become tenable for the >complex molecules that compose life forms. This is the capper, and it's a howler. He implies that it will never become possible to slow, stop, or reverse aging in humans or any other animals, because we can't even do it for simple inanimate objects. First of all, we can and frequently do use many methods to slow deterioration of inanimate objects, e.g. by galvanizing iron. We also frequently reverse "aging" of machines by a process known as "repair." Beyond that, animals are dynamic systems with self-modifying programs, which most inanimate systems are not, and even in nature there is lots of activity in self-repair. When you cut yourself, your skin heals itself. Some animals can regenerate lost limbs. And we are not limited by what nature has already accomplished. Hayflick needs a guide dog; otherwise he is likely to wander into traffic. Robert Ettinger J Gerontol A Biol Sci Med Sci. 2004 Jun;59(6):B573-8. Aging: the reality: "anti-aging" is an oxymoron. Hayflick L. No intervention will slow, stop, or reverse the aging process in humans. Whether anti-aging medicine is, or is not, a legitimate science is completely dependent upon the definition of key terms that define the finitude of life: longevity determination, aging, and age-associated diseases. Only intervention in the latter by humans has been shown to affect life expectancy. When it becomes possible to slow, stop, or reverse the aging process in the simpler molecules that compose inanimate objects, such as machines, then that prospect may become tenable for the complex molecules that compose life forms. Most of the resources available under the rubric "aging research" are not used for that purpose at all, thus making the likelihood of intervention in the process even more remote. If age changes are the greatest risk factor for age-associated diseases (an almost universal belief), then why is the study of aging virtually neglected?
