This book provides concrete scientific basis that we can conceive the possibility of modifying or even completely canceling aging process, despite the fact that aging is commonly regarded as the result of the overall effects of many uncontrollable degenerative phenomena. The authors illustrate in detail the mechanisms by which cells and the whole organism age. Actions by which it is possible, or will be possible within a limited time, to operate for modifying aging are also debated. The discussion is conducted within the frame and the concepts of evolutionary medicine, which is also indispensable for distinguishing between the manifestations of aging and: (i) diseases that worsen with age, and (ii) acceleration of normal aging rates, caused by unhealthy lifestyle habits and other avoidable factors. The book also discusses the impact of aging on overall mortality and the strange situation that, according to official statistics, aging does not exist as cause of death. This book is a turning point between a gerontology and geriatrics conceived as the study and vain treatment of an incurable condition and one in which these disciplines examine the how and why of a physiological phenomenon that can be modified up to a possible total control. This means transforming the medical prevention and treatment of physiological aging from the greatest failure to the greatest success of medicine.

Presenting the latest research in the biology of aging, this volume addresses important theoretical issues focusing on the basis for why humans live as long as they do. Expert authors combine three general paradigms of aging research: demographic studies, evolutionary studies, and studies of biological mechanisms. Topics explored include: Why does aging occur? Cellular aging Models in aging research Modern approaches to the mechanisms of aging The genetics of behavioral aging

A critical gerontology requires more than a simple elaboration of existing humanistic scholarship on aging. This exceptional new work introduces a basis for genuine dialogue across humanistic, scientific, and professional disciplines. Among the topics addressed are industrial employment, retirement, life styles of older women, and biological research. From philosophical reflections on the ìthird ageî to critical perspectives on institutional adaptations to an aging society, this book presents a wide range of provocative thought.

This unique book looks at the biology of aging from a fundamentally new perspective, one based on evolutionary theory rather than traditional concepts which emphasize molecular and cellular processes. The basis for this approach lies in the fact that natural selection, as a powerful determining force, tends to decline in importance with age. Many of the characteristics we associate with aging, the author argues, are more the result of this decline than any mechanical imperative contained within organic structures. This theory in turn yields the most fruitful avenues for seeking answers to the problem of aging, and should be recognized as the intellectual core of gerontology and the foundation for future research. The author ably surveys the vast literature on aging, presenting mathematical, experimental, and comparative findings to illustrate and support the central thesis. The result is the first complete synthesis of this vital field. Evolutionary biologists, gerontologists, and all those concerned with the science of aging will find it a stimulating, strongly argued account.

Gerontology refers to the study of the biological, psychological, cognitive and sociocultural aspects of aging. An important sub-field of gerontology is biogerontology, which is concerned with the biological process of aging, its evolutionary origin and the possible potential interventions in the process. It investigates the causes, effects and mechanisms of aging. Geriatrics is a field of medicine, which is focused on the health care for the elderly. As an individual ages, there is a gradual decline in the physiological reserve in organs. This results in the development of diseases and complications. Instability, immobility, impaired intellect and memory, and incontinence are the major impairments that occur in the elderly. Many of these problems can be addressed with medications and adequate care. This book is a valuable compilation of topics, ranging from the basic to the most complex advancements in the fields of gerontology and geriatrics. From theories to research, case studies related to all medical aspects of relevance to these fields have been included herein. It will prove to be immensely beneficial to students and researchers in this field.

Goldsmith provides a historical review of biological aging theories including underlying evolution and genetics issues and describes exciting recent discoveries and new theories that are causing renewed interest in aging-by-design.

Gerontology deals with the scientific study of old age, the process of ageing, and the particular problems of old people. It focuses on the biological, psychological, cognitive, cultural and social aspects of ageing. Some of its subfields are biogerontology, social gerontology, environmental gerontology and jurisprudential gerontology. Biogerontology is associated with the biological aging process and its evolutionary origins. Social gerontology is a specialization in the study and working with older adults. Environmental gerontology deals with the interaction between aging persons and their social and physical environments. Jurisprudential gerontology is concerned with the relationship between laws and the aging process. This book traces the progress of this field and highlights some of its key concepts and applications. It will help the readers in keeping pace with the rapid changes in gerontology. Some of the diverse topics covered in this book address the varied branches that fall under this category.
