YouTube Description

as posted by the channel

In this episode, I interview Dr. Robert Sapolsky, Ph.D., Professor of Biology, Neurology & Neurosurgery at Stanford University. We discuss stress, what defines short-term versus long-term stress and how stress can be beneficial or detrimental depending on the context. We also discuss stress mitigation and how our sense of control over stress-mitigation techniques, including exercise, determines health outcomes. Dr. Sapolsky explains some of the key effects of the hormone testosterone—how it can amplify pre-existing tendencies for aggression or sexual behavior but does not produce those behaviors per se. He also explains how testosterone impacts our social hierarchies, sense of confidence and willingness to embrace challenges of different kinds. He further explains how our behaviors and perceptions shape testosterone levels. We also discuss estrogen and the powerful role it plays in brain development, health and longevity. Finally, we discuss free will, what it means to have free will and whether we have any, including how knowledge alone might allow us to make better decisions for ourselves and society.
