How can we turn back the clock? Health food, gyms and cosmetic companies promise us everlasting youth, but the effects of aging are caused by complex biological processes at the level of the cell. The author shows what we can do to protect ourselves and what exciting breakthroughs scientists are still working on, and he asks which industries benefit by peddling dubious information and dubious remedies. He also looks at why we are so keen to deny that we are aging, when indeed, aging is a part of life - for everything from bacteria to humans.
MUST WE AGE? A long life in a healthy, vigorous, youthful body has always been one of humanity's greatest dreams. Recent progress in genetic manipulations and calorie-restricted diets in laboratory animals hold forth the promise that someday science will enable us to exert total control over our own biological aging. Nearly all scientists who study the biology of aging agree that we will someday be able to substantially slow down the aging process, extending our productive, youthful lives. Dr. Aubrey de Grey is perhaps the most bullish of all such researchers. As has been reported in media outlets ranging from 60 Minutes to The New York Times, Dr. de Grey believes that the key biomedical technology required to eliminate aging-derived debilitation and death entirely—technology that would not only slow but periodically reverse age-related physiological decay, leaving us biologically young into an indefinite future—is now within reach. In Ending Aging, Dr. de Grey and his research assistant Michael Rae describe the details of this biotechnology. They explain that the aging of the human body, just like the aging of man-made machines, results from an accumulation of various types of damage. As with man-made machines, this damage can periodically be repaired, leading to indefinite extension of the machine's fully functional lifetime, just as is routinely done with classic cars. We already know what types of damage accumulate in the human body, and we are moving rapidly toward the comprehensive development of technologies to remove that damage. By demystifying aging and its postponement for the nonspecialist reader, de Grey and Rae systematically dismantle the fatalist presumption that aging will forever defeat the efforts of medical science.
Entropy is a measure of order and disorder. If left alone, aging systems go spontaneously from youthful, low entropy and order to old, high entropy and disorder. This book presents the commonality of entropy principles which govern the birth, maturation, and senescent history of aging humans, corporations, and the universe. Mainly we introduce an entropy theory of aging, based on the non-equilibrium thermodynamic ideas of Ilya Prigogine, leading to the thermodynamic concepts of Excess Entropy (EE) and Excess Entropy Production (EEP). We describe the aging process in humans in terms of the EE and EEP concepts. This book also describes the informational entropy theory and equations of Claude Shannon and the six Hershey parameters which trace and mark the lifecycle of corporations. To conclude, this volume uses classical and informational entropy concepts, equations and calculations to explain the birth, evolution, and death of our aging universe, and all of this in relation to the concept of Infinity./a
In 1986 Dr. David Snowdon, one of the world’s leading experts on Alzheimer’s disease, embarked on a revolutionary scientific study that would forever change the way we view aging—and ultimately living. Dubbed the “Nun Study” because it involves a unique population of 678 Catholic sisters, this remarkable long-term research project has made headlines worldwide with its provocative discoveries. Yet Aging with Grace is more than a groundbreaking health and science book. It is the inspiring human story of these remarkable women—ranging in age from 74 to 106—whose dedication to serving others may help all of us live longer and healthier lives. Totally accessible, with fascinating portraits of the nuns and the scientists who study them, Aging with Grace also offers a wealth of practical findings: • Why building linguistic ability in childhood may protect against Alzheimer’s • Which ordinary foods promote longevity and healthy brain function • Why preventing strokes and depression is key to avoiding Alzheimer’s • What role heredity plays, and why it’s never too late to start an exercise program • How attitude, faith, and community can add years to our lives A prescription for hope, Aging with Grace shows that old age doesn’t have to mean an inevitable slide into illness and disability; rather it can be a time of promise and productivity, intellectual and spiritual vigor—a time of true grace.
Why do we still tolerate stereotypes and discrimination based on age? This bold account of the history and present-day realities of ageism by a nationally recognized gerontologist and speaker uncovers ageism's roots, impact, and how each of us can create a new reality of elderhood. Ageism Unmasked shifts the lens, enabling us to see that we tolerate, and sometimes actively promote, attitudes and behaviors toward differently aged people that we would reject and condemn if applied to any other group. It peels back the layers to expose how cultural norms and unconscious prejudices have seeped into our lives, silently shaping our treatment of others based on their age and our own misconceptions about aging—and about ourselves. Offering an all-inclusive approach, Dr. Tracey Gendron reveals the biases behind our false understanding of aging, sharing powerful opportunities for personal growth along with strategies to help create an anti-ageist society. Ageism Unmasked will help readers let go of our desperate need to stay young… exposing how we personally, systematically, structurally, and institutionally stigmatize being old. Ageism Unmasked will help readers appreciate both the challenges and opportunities of how we all age… showing how ageism is prejudice towards both younger and older people. Ageism Unmasked will help readers reset our expectations for getting old… providing the tools to anticipate and experience elderhood as a time of renewed meaning and purpose, empowering each of us to create our own definition of successful aging. Ageism Unmasked continues Dr. Gendron's transformative work inspiring people of all ages to embrace aging as our universal and lifelong process of developing over time — biologically, psychologically, socially, and spiritually.
Anyone who has watched a wrinkle slowly gouge their face like a strip mine, or has been disturbed by a loss of memory, has uncomfortably confronted the human ageing process. The inexorable march of time on our bodies begs an important question: why do we have to grow old? Written in everyday language, The Clock of Ages takes us on a tour of the ageing human body - all from a research scientist's point of view. From the deliberate creation of organisms that live three times their natural span to the isolation of human genes that may allow us to do the same, The Clock of Ages also examines the latest discoveries in geriatric genetics. Sprinkled throughout the pages are descriptions of the aging of many historical figures, such as Florence Nightingale, Jane Austen, Bonaparte and Casanova. These stories underscore the common bond that unites us all: they aged, even as we do. The Clock of Ages tells you why.
Let’s face it: almost everyone fears growing older. We worry about losing our looks, our health, our jobs, our self-esteem—and being supplanted in work and love by younger people. It feels like the natural, inevitable consequence of the passing years, But what if it’s not? What if nearly everything that we think of as the “natural” process of aging is anything but? In Agewise, renowned cultural critic Margaret Morganroth Gullette reveals that much of what we dread about aging is actually the result of ageism—which we can, and should, battle as strongly as we do racism, sexism, and other forms of bigotry. Drawing on provocative and under-reported evidence from biomedicine, literature, economics, and personal stories, Gullette probes the ageism thatdrives discontent with our bodies, our selves, and our accomplishments—and makes us easy prey for marketers who want to sell us an illusory vision of youthful perfection. Even worse, rampant ageism causes society to discount, and at times completely discard, the wisdom and experience acquired by people over the course of adulthood. The costs—both collective and personal—of this culture of decline are almost incalculable, diminishing our workforce, robbing younger people of hope for a decent later life, and eroding the satisfactions and sense of productivity that should animate our later years. Once we open our eyes to the pervasiveness of ageism, however, we can begin to fight it—and Gullette lays out ambitious plans for the whole life course, from teaching children anti-ageism to fortifying the social safety nets, and thus finally making possible the real pleasures and opportunities promised by the new longevity. A bracing, controversial call to arms, Agewise will surprise, enlighten, and, perhaps most important, bring hope to readers of all ages.
“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.
