David Sinclair, Ph.D.: Slowing aging – sirtuins, NAD, and the epigenetics of aging (EP.27)

“This is a lesson for anyone who's listening who thinks that getting to somewhere like this is easy. You have to be massively determined, you have to have grit, and I just wouldn't give up because there's nothing else I want to do in my life.” —David Sinclair

In this episode, David A. Sinclair, Ph.D., a Professor in the Department of Genetics at Harvard Medical School and co-Director of the Paul F. Glenn Center for the Biological Mechanisms of Aging, provides insight into why we age and how to slow its effects based on his remarkable work on the role of sirtuins and NAD in health and diseases. He also presents the case that stabilizing the epigenetic landscape may be the linchpin in counteracting aging and disease.
