As we confront our own mortality, we might ask, "What has my long life meant and how have the years shaped me?" or "How long must I suffer?" Such questions reflect time-consciousness, the focus of this classic volume. The authors, from diverse disciplines in gerontology, act as guides in the exploration of the realms of time in later life and their meanings. As they examine how the study of time can give new meanings to aging, they also consider the religious and spiritual questions raised when human beings consider the temporal boundaries of life. This volume honors Melvin Kimble's contributions to gerontology and represents a new direction in the study of religion, spirituality, and aging.

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.

Baars explores philosophers from Plato to Foucault as they consider the meaning of aging—and wisdom—in our society. In this deeply considered meditation on aging in Western culture, Jan Baars argues that, in today’s world, living longer does not necessarily mean living better. He contends that there has been an overall loss of respect for aging, to the point that understanding and “dealing with” aging people has become a process focused on the decline of potential and the advance of disease rather than on the accumulation of wisdom and the creation of new skills. To make his case, Baars compares and contrasts the works of such modern-era thinkers as Foucault, Heidegger, and Husserl with the thought of Plato, Aristotle, Sophocles, Cicero, and other Ancient and Stoic philosophers. He shows how people in the classical period—less able to control health hazards—had a far better sense of the provisional nature of living, which led to a philosophical and religious emphasis on cultivating the art of living and the idea of wisdom. This is not to say that modern society’s assessments of aging are insignificant, but they do need to balance an emphasis on the measuring of age with the concept of "living in time." Gerontologists, philosophers, and students will find Baars' discussion to be a powerful, perceptive conversation starter.

We are obsessed with time. However hard we might try, it is almost impossible to spend even one day without the marker of a clock. But how much do we understand about time, and is it possible to retrain our brains and improve our relationship with it? Drawing on the latest research from the fields of psychology, neuroscience, and biology, and using original research on the way memory shapes our understanding of time, acclaimed writer and broadcaster Claudia Hammond delves into the mysteries of time perception. Along the way, she introduces us to an extraordinary array of colourful characters willing to go to great lengths in the interests of research, such as the French speleologist Michel, who spends two months in an ice cave in complete darkness. Time Warped shows us how to manage our time more efficiently, speed time up and slow it down at will, plan for the future with more accuracy, and, ultimately, use the warping of time to our own advantage.

Although philosophy, religion, and civic cultures used to help people prepare for aging and dying well, this is no longer the case. Today, aging is frequently seen as a problem to be solved and death as a harsh reality to be masked. In part, our cultural confusion is rooted in an inadequate conception of the human person, which is based on a notion of absolute individual autonomy that cannot but fail in the face of the dependency that comes with aging and decline at the end of life. To help correct the ethical impoverishment at the root of our contemporary social confusion, The Evening of Life provides an interdisciplinary examination of the challenges of aging and dying well. It calls for a re-envisioning of cultural concepts, practices, and virtues that embraces decline, dependency, and finitude rather than stigmatizes them. Bringing together the work of sociologists, anthropologists, philosophers, theologians, and medical practitioners, this collection of essays develops an interrelated set of conceptual tools to discuss the current challenges posed to aging and dying well, such as flourishing, temporality, narrative, and friendship. Above all, it proposes a positive understanding of thriving in old age that is rooted in our shared vulnerability as human beings. It also suggests how some of these tools and concepts can be deployed to create a medical system that better responds to our contemporary needs. The Evening of Life will interest bioethicists, medical practitioners, clinicians, and others involved in the care of the aging and dying. Contributors: Joseph E. Davis, Sharon R.
