"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.

An uplifting review of the science suggesting that "prolonged healthy lifespans are in sight." According to Sinclair (Genetics/Harvard Medical School), scientists have discovered what causes aging. They've also discovered how to treat it because, despite what doctors and philosophers have claimed throughout history, aging is not inevitable. It's a disease. Throughout the book, the author's enthusiasm jumps off the page. Scientifically inclined readers may be occasionally turned off by his affection for dramatic stories of individuals who defy aging, but they cannot deny that he is an acclaimed, award-winning scientist who works hard to explain his groundbreaking research and that of laboratories around the world. Beginning at the beginning, he writes that "way back in the primordium, the ancestors of every living thing on this planet today evolved to sense DNA damage, slow cellular growth, and divert energy to DNA repair until it was fixed--what I call the survival circuit." In the 1950s, scientists discovered that DNA damage occurs throughout life. Since it's disastrous for a cell to divide with broken DNA, repair mechanisms suppress growth and reproduction until they're finished. Cells that don't divide live longer. Insects and mice mature quickly, reproduce, and soon die. Elephants and whales grow slowly and live much longer lives. Cells of the bristlecone pine, the oldest of which is nearly 5,000 years old, show no signs of aging. Researchers have discovered the mechanism of growth suppression in hormones and also in genes that produce such specific enzymes. These longevity enhancers respond to stress but also to exercise, intermittent fasting, low-protein and low-calorie diets, and several pharmaceuticals that, the author assures readers, will soon emerge from the laboratory. Also in the works are DNA monitoring and reprogramming, already well advanced in animals, that can detect malfunctions and reset the aging clock. A highly optimistic review of anti-aging science that may persuade older readers that they were born too soon.COPYRIGHT(2019) Kirkus Reviews, ALL RIGHTS RESERVED.
