David A. Sinclair, Ph.D., A.O. is a Professor in the Department of Genetics and co-Director of the Paul F. Glenn Center for Biology in Aging Research at Harvard Medical School. He is best known for his work on understanding why we age and how to slow its effects. He’s also living proof of longevity. This week on Twitter he was quoted as saying:

“You know your lifestyle is working when old photos make you look older than you look now.” David Sinclair Ph.D.

It’s an 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?  Sinclair believes we can. The scientist has spent most of his professional life searching for answers. In his book, Lifespan, he reveals a bold new theory for why we age.

Choose your lifespan

Through a page-turning narrative, he invites you into the process of scientific discovery and reveals emerging technologies and simple lifestyle changes—such as intermittent fasting, cold exposure, exercising with the right intensity, and eating less meat. All of which has been shown to help us live younger and healthier for longer.

That forever child

In an interview, Catherine Elton from Boston Magazine described the scientist as follows: “David Sinclair has a tendency to live in the future. The first time that thought crossed my mind, we were hurtling toward Worcester in his Tesla, on our way to visit one of his many companies working on an antidote to aging.

Sinclair told me he’d recently discovered, using a health-tracking device, that he’s shaved a decade off his life: Biologically speaking, he is now 40, not 50. I took a good look at him. Except for the pillow he sat on while he drove, the wrinkles that formed around his eyes when he flashed his mischievous grin, and the note scrawled on the back of his hand (lest he forgets something he has to do), there was no way in hell he looked anywhere near 50. He is slight of build, with nary a gray hair, and bears a passing resemblance to that forever child Alfred E. Neuman. He even says he feels like a kid, too.”
