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.

People are living longer, creating an unexpected boom in the elderly population. Longevity is increasing not only in wealthy countries but in developing nations as well. In response, many policy makers and scholars are preparing for a global crisis of aging. But for too long, Western experts have conceived of aging as a universal predicament—one that supposedly provokes the same welfare concerns in every context. In the twenty-first century, Kavita Sivaramakrishnan writes, we must embrace a new approach to the problem, one that prioritizes local agendas and values. As the World Ages is a history of how gerontologists, doctors, social scientists, and activists came to define the issue of global aging. Sivaramakrishnan shows that transnational organizations like the United Nations, private NGOs, and philanthropic foundations embraced programs that reflected prevailing Western ideas about development and modernization. The dominant paradigm often assumed that, because large-scale growth of an aging population happened first in the West, developing societies will experience the issues of aging in the same ways and on the same terms as their Western counterparts. But regional experts are beginning to question this one-size-fits-all model and have chosen instead to recast Western expertise in response to provincial conditions. Focusing on South Asia and Africa, Sivaramakrishnan shows how regional voices have argued for an approach that responds to local needs and concerns. The research presented in As the World Ages will help scholars, policy makers, and advocates appreciate the challenges of this recent shift in global demographics and find solutions sensitive to real life in diverse communities.

"(This work) promises to raise the level and transform the nature of discourse on the relations of Christianity and science . . . (Funkenstein) leaps fearlessly from one philosophical mountaintop to another, comparing and contrasting doctrines in an amazing display of intellectual dexterity. The result is a bold study of ideas . . . bristling with insight and perceptive reinterpretation of familiar episodes in the history of natural philosophy".--David C.

The study of pre-modern anthropology requires the close examination of the relationship between nature and human society, which has been both precarious and threatening as well as productive, soothing, inviting, and pleasurable. Much depends on the specific circumstances, as the works by philosophers, theologians, poets, artists, and medical practitioners have regularly demonstrated. It would not be good enough, as previous scholarship has commonly done, to examine simply what the various writers or artists had to say about nature. While modern scientists consider just the hard-core data of the objective world, cultural historians and literary scholars endeavor to comprehend the deeper meaning of the concept of nature presented by countless writers and artists. Only when we have a good grasp of the interactions between people and their natural environment, are we in a position to identify and interpret mental structures, social and economic relationships, medical and scientific concepts of human health, and the messages about all existence as depicted in major art works. In light of the current conditions threatening to bring upon us a global crisis, it matters centrally to take into consideration pre-modern discourses on nature and its enormous powers to understand the topoi and tropes determining the concepts through which we perceive nature. Nature thus proves to be a force far beyond all human comprehensibility, being both material and spiritual depending on our critical approaches.

The second edition of this book has been completely updated. It studies the history and gives an analysis of extreme climate change on Earth. In order to provide a long-term perspective, the first chapter briefly reviews some of the wild gyrations that occurred in the Earth's climate hundreds of millions of years ago: snowball Earth and hothouse Earth. Coming closer to modern times, the effects of continental drift, particularly the closing of the Isthmus of Panama are believed to have contributed to the advent of ice ages in the past three million years. This first chapter sets the stage for a discussion of ices ages in the geological recent past (i.e. within the last three million years, with an emphasis on the last few hundred thousand years).

The Noble Savage, earthly paradise, the original condition of human beings, cynicism, Christianity . . . "All of us men were born in the first man without vice, and all of us lost the innocence of our nature by the sin of the same man. Thence our inherited mortality, thence the manifold corruptions of body and mind, thence ignorance, distress, useless cares, illicit lusts, sacrilegious errors, empty fear, harmful love, unwarranted joys, punishable counsels, and a number of miseries no smaller than that of our crimes."—St. Prosper of Aquitania, quoted in Primitivism and Related Ideas in the Middle Ages This volume of essays, written by George Boas in collaboration with Arthur O. Lovejoy, was originally intended to be the second in a series of four documenting the history of primitivism and related ideas about goodness in the world. Covering the Middle Ages, these essays underscore the continuity between pagan and Christian cultures with respect to concepts of primitivism and examine the latter period's modifications of a group of favorite classical themes. They demonstrate the growth of primitivism and anti-primitivism from the first through the thirteenth centuries and include a discussion of such subjects as the Noble Savage, earthly paradise, the original condition of human beings, and cynicism and Christianity. They also, as Boas suggests in his preface, "drive the piles for a bridge between the Renaissance and Classical Antiquity, although the superstructure itself remains to be constructed."
