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.

How is it that a patch of flickering light on a wall can produce experiences that engage our imaginations and can feel totally real? From the vertigo of a skydive to the emotional charge of an unexpected victory or defeat, movies give us some of our most vivid experiences and most lasting memories. They reshape our emotions and worldviews--but why? In Flicker, Jeff Zacks delves into the history of cinema and the latest research to explain what happens between your ears when you sit down in the theatre and the lights go out. Some of the questions Flicker answers: Why do we flinch when Rocky takes a punch in Sylvester Stallone's movies, duck when the jet careens towards the tower in Airplane, and tap our toes to the dance numbers in Chicago or Moulin Rouge? Why do so many of us cry at the movies? What's the difference between remembering what happened in a movie and what happened in real life--and can we always tell the difference? To answer these questions and more, Flicker gives us an engaging, fast-paced look at what happens in your head when you watch a movie.

The book tells the story of how we never evolved to exercise - to do voluntary physical activity for the sake of health. Using his own research and experiences throughout the world, the author recounts how and why humans evolved to walk, run, dig, and do other necessary and rewarding physical activities while avoiding needless exertion. Drawing on insights from biology and anthropology, the author suggests how we can make exercise more enjoyable, rather that shaming and blaming people for avoiding it
