“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.

“I have written about the brilliant work of David Sinclair for over fifteen years and have watched his life’s mission of using science to slow the scourge of old age and dying move from the outer edge to more mainstream biology (he’s still pushing boundaries!) as his careful work in the lab has steadily shed light on how the mechanisms of aging work in humans and in other organisms. In Lifespan, the full force of his optimism, humor, and soft-spoken eloquence as a storyteller-scientist come through. I was charmed and delighted by his skill at blending his own life’s narrative and others’ with clear and levelheaded explanations of some very complex and emerging science. I’m hoping we have David Sinclair with us and doing his science and writing books for another 500 years, give or take a century.”
