In this groundbreaking conversation, Professor of Genetics and longevity scientist, Dr. David Sinclair, A.O., Ph.D., joins Sarah Grynberg to unpack the future of human aging, the science of longevity, and how we live today impacts how we age tomorrow.

From reversing blindness in mice to exploring treatments that could one day delay menopause and extend healthy human life, this episode will completely change the way you think about your body, your health, and your future.
