The growth of public and professional interest in “anti-aging” interventions raises an ethical problem for the medical profession with important policy implications: is human aging an appropriate target for medical intervention? At present there is nothing that medicine can prescribe to combat aging that has any scientific validation (Olshansky, Hayflick, Carnes, 2002). But biogerontologists are making headway, and a central research agenda for that scientific community is to provide clinicians with the tools they require to make anti-aging medicine a reality. If they could intervene to slow the aging process, would “anti-aging” clinicians be practicing health care or would they be simply using the mantle of medicine to do something else entirely, which responsible health professionals should eschew?
