Book Description
Each species has its own characteristic aging trajectory coded by a species-specific developmental program. This developmental program is triggered at the time of fertilization, hence aging begins at conception. Within a species there are considerable variations in the aging phenotype between individuals due to the plasticity of the developmental process and its inherent stochasticity. The evolution of a species is due to genetic changes in its underlying developmental program and when enough genetic changes have accumulated a new species emerges with its own characteristic aging phenotype. Therefore, speciation and aging are linked processes. Over the evolutionary course of the human lineage, culture has been an important driver of evolutionary change. Culture is not restricted to the human lineage but only humans have evolved cumulative culture; the transmission of modified cultural practices across generations. Early cultural innovations such as toolmaking, agriculture and dairy farming had a utilitarian function. However, over the past 100 to 150 years, there has been a significant change in the pace and nature of cultural innovations. Although many cultural innovations still have a utilitarian function, a new category of cultural innovations has emerged that have "entertainment" functions in the domains of social communication and information transfer. In addition, cultural practices by the tobacco, food and technological industries have been used to modify population behaviors, physiology and beliefs. Over the past 50 to 75 years, there has emerged so called chronic non-infectious diseases, which occurrence parallels the development of these new cultural innovations and practices. In addition, culture has now become the primary driver of human evolution. In answer to the question posed by the title of this book, aging is not a disease and diseases are cultural constructs used to define variants in the aging process.

Book Description
Aging is a natural phenomenon that is peculiar to all living things. However, accumulating findings indicate that senescence could be postponed or prevented by certain approaches. Substantial evidence has emerged supporting the possibility of radical human health and lifespan extension, in particular through pharmacological modulation of aging. A number of natural dietary ingredients and synthetic drugs have been assumed to have geroprotective potential. In the development of anti-aging therapeutics, several cell, insect, and animal models may provide useful starting points prior to human studies. This book provides an overview of current research aimed to search for life-extending medications and describes pharmacological aspects of anti-aging medicine. Readers are introduced to the fascinating historical background of geroprotection in the first chapter. In-depth information on models for investigating geroprotective drugs precedes a section covering anti-aging properties of pharmaceutical compounds, such as calorie restriction mimetics, autophagy inducers, senolytics and mitochondrial antioxidants. Finally, strategies to translate discoveries from aging research into drugs and healthcare policy perspectives on anti-ageing medicine are provided to give a complete picture of the field. A timely and carefully edited collection of chapters by leading researchers in the field, this book will be a fascinating and useful resource for pharmacologists, gerontologists and any scientifically interested person wishing to know more about the current status of research into anti-aging remedies, challenges and opportunities.

Book Description
Age as Disease explores the foundations of gerontology as a discipline to examine the ways contemporary society constructs old age as a disease-state. Framed throughout as ‘gerontological hygeine’, this book examines contemporary regimes, strategies and treatment protocols deployed throughout Australia, the United States, and the United Kingdom. The book deploys critical cultural theories such as biopolitics, somatechnics, ethics, and governmentality to examine how anti-aging technologies operate to problematise the aging body as always-already diseased, and how these come to constitute a movement of abolition, named here as ‘gerontological hygiene’.

Book Description
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.

Book Description
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.
