How long can humans live? Is immortality possible? Just what is the aging process? The aging and inevitable death of the human body have inspired more myths and outrageous quackery than anything else subject to scientific inquiry. . . . Now comes a most fascinating book, insightful and scholarly, to provide what answers have emerged so far.'San Francisco ChronicleHere, at last, preeminent cell biologist Leonard Hayflick presents the truth about human aging. Based on more than thirty years of pioneering research in the field, How and Why We Age explores not only how our major biological systems change as we grow older, but also examines the intangible alterations in our modes of thinking and feeling, our moods and sexual desires, our personality traits and our memories.With the immediacy of the latest scientific discoveries, Dr. Hayflick explains how aging affects every part of the body, and dispels many of the most persistent aging myths, to show that:* Hearts do not naturally get weaker with age.* Regular exercise and a lowfat diet won't slow aging.* Curing cancer would only add two years to the average sixtyfiveyearold American life. Curing heart disease, however would add fourteen years.* Only five percent of people over the age of sixtyfive are in nursing homes* No human has livedor probably can livepast 120 years.Gracefully written, clearly organized, and packed with essential facts and statistics, How and Why We Age is a landmark study of the aging process for readers of all ages.'Written in clear, nontechnical language, it is an excellent introduction to the scientific and demographic literature on this multifaceted subject.'Nature
