The attitudes of conservative gerontologists towards healthy life extension, the loud "anti-aging" marketplace and the serious pursuit of longevity research are summed up in a new book. "The Gerontological Society of America's 2004 peer-reviewed article series on the truth of anti-aging medicine is now available in a single volume. ... Supervised by editors S. Jay Olshansky, PhD, Leonard Hayflick, PhD, and Thomas T. Perls, MD, MPH, this book focuses on the history of anti-aging research, the debate among scientists on the societal implications of modifying the biological rate of aging, and the reality of what is currently known about the aging process. Further attention is given to growth hormones and supplements and legal issues associated with the practice of anti-aging medicine."
