Synopsis How and why We Age by : Leonard Hayflick

"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 Chronicle Here, 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 low-fat diet won't slow aging. * Curing cancer would only add two years to the average sixty-five-year-old American life. Curing heart disease, however would add fourteen years. * Only five percent of people over the age of sixty-five are in nursing homes * No human has lived--or probably can live--past 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 multifacetedsubject." --Nature

Synopsis Lifespan by : David A. Sinclair

A NEW YORK TIMES BESTSELLER “Brilliant and enthralling.”​ —The Wall Street Journal A paradigm-shifting book from an acclaimed Harvard Medical School scientist and one of Time’s most influential people. It’s a seemingly undeniable truth that aging is inevitable. But what if everything we’ve been taught to believe about aging is wrong? What if we could choose our lifespan? In this groundbreaking book, Dr. David Sinclair, leading world authority on genetics and longevity, reveals a bold new theory for why we age. As he writes: “Aging is a disease, and that disease is treatable.” This eye-opening and provocative work takes us to the frontlines of research that is pushing the boundaries on our perceived scientific limitations, revealing incredible breakthroughs—many from Dr. David Sinclair’s own lab at Harvard—that demonstrate how we can slow down, or even reverse, aging. The key is activating newly discovered vitality genes, the descendants of an ancient genetic survival circuit that is both the cause of aging and the key to reversing it. Recent experiments in genetic reprogramming suggest that in the near future we may not just be able to feel younger, but actually become younger. Through a page-turning narrative, Dr. Sinclair invites you into the process of scientific discovery and reveals the emerging technologies and simple lifestyle changes—such as intermittent fasting, cold exposure, exercising with the right intensity, and eating less meat—that have been shown to help us live younger and healthier for longer. At once a roadmap for taking charge of our own health destiny and a bold new vision for the future of humankind, Lifespan will forever change the way we think about why we age and what we can do about it.

Synopsis Ageless by : Andrew Steele

“A fascinating look at how scientists are working to help doctors treat the aging process itself, helping us all to lead longer, healthier lives.” —Sanjay Gupta, MD Aging—not cancer, not heart disease—is the underlying cause of most human death and suffering. The same cascade of biological changes that renders us wrinkled and gray also opens the door to dementia and disease. We work furiously to conquer each individual disease, but we never think to ask: Is aging itself necessary? Nature tells us it is not: there are tortoises and salamanders who are spry into old age and whose risk of dying is the same no matter how old they are, a phenomenon known as “biological immortality.” In Ageless, Andrew Steelecharts the astounding progress science has made in recent years to secure the same for humans: to help us become old without getting frail, to live longer without ill health or disease.

Synopsis Why We Age by : Steven N. Austad

Why has the life span of the average American increased from 48 to 75 years in this century alone? . . . If the body is a machine that simply wears out, why do some cells seem immortal? . . . Is there an aging gene? And can we control it? . . . Can antioxidants and hormone therapy actually slow the aging process and extend life? Steven Austad s compelling book investigates the history, the theories, and the personalities behind the quest to understand the nature of aging. Here is hard evidence from the front lines of research that science is finally closing in on the fundamental processes of human biology and life. "Austad s book can be read with pleasure and profit by any intelligent person with a smattering of biological knowledge." Science "In this clear, engrossing overview, Austad takes the sting out of a subject that will ultimately capture us all." Publishers Weekly "Why We Age is remarkably rigorous in its analysis and thorough scope. . . . A comprehensive examination of its topic." Science Editors, Amazon.com "The problem with long life is that one keeps getting older; here s an able and clearly written summary of the latest theories on why we age and what might be done to ameliorate the process." Kirkus Reviews

Synopsis Aging: The Paradox of Life by : Robin Holliday

For centuries people have puzzled over the inevitability of human aging. At the end of the 20th century a remarkable scientific discovery emerged, based on a series of important interconnected insights over quite a long period of time. The aim of this book is to dispel ignorance by explaining in non-technical language what are the reasons for aging and the myth of excessive prolongation of life.

Synopsis Epigenetics of Aging by : Trygve O. Tollefsbol

Recent studies have indicated that epigenetic processes may play a major role in both cellular and organismal aging. These epigenetic processes include not only DNA methylation and histone modifications, but also extend to many other epigenetic mediators such as the polycomb group proteins, chromosomal position effects, and noncoding RNA. The topics of this book range from fundamental changes in DNA methylation in aging to the most recent research on intervention into epigenetic modifications to modulate the aging process. The major topics of epigenetics and aging covered in this book are: 1) DNA methylation and histone modifications in aging; 2) Other epigenetic processes and aging; 3) Impact of epigenetics on aging; 4) Epigenetics of age-related diseases; 5) Epigenetic interventions and aging: and 6) Future directions in epigenetic aging research. The most studied of epigenetic processes, DNA methylation, has been associated with cellular aging and aging of organisms for many years. It is now apparent that both global and gene-specific alterations occur not only in DNA methylation during aging, but also in several histone alterations. Many epigenetic alterations can have an impact on aging processes such as stem cell aging, control of telomerase, modifications of telomeres, and epigenetic drift can impact the aging process as evident in the recent studies of aging monozygotic twins. Numerous age-related diseases are affected by epigenetic mechanisms. For example, recent studies have shown that DNA methylation is altered in Alzheimer’s disease and autoimmunity. Other prevalent diseases that have been associated with age-related epigenetic changes include cancer and diabetes. Paternal age and epigenetic changes appear to have an effect on schizophrenia and epigenetic silencing has been associated with several of the progeroid syndromes of premature aging. Moreover, the impact of dietary or drug intervention into epigenetic processes as they affect normal aging or age-related diseases is becoming increasingly feasible.

Synopsis Providing Healthy and Safe Foods As We Age by : Institute of Medicine

Does a longer life mean a healthier life? The number of adults over 65 in the United States is growing, but many may not be aware that they are at greater risk from foodborne diseases and their nutritional needs change as they age. The IOM's Food Forum held a workshop October 29-30, 2009, to discuss food safety and nutrition concerns for older adults.
