In this Huberman Lab Essentials episode, my guest is Dr. David Sinclair, PhD, a professor of genetics at Harvard Medical School and a leading expert on the biology of aging.
We discuss the cellular and molecular mechanisms of aging—and how specific behaviors, such as fasting, regular exercise and NAD⁺-boosting compounds like NMN, can activate the body’s natural longevity pathways. This discussion highlights how lifestyle choices profoundly influence the aging process and may even slow or reverse key aspects of biological aging.
