In this episode, Robert Sapolsky, Ph.D., discusses the widespread impact of stress on our physical and emotional health as well as the mechanisms by which it can precipitate chronic illness, dementia, depression, and more. He also provides insight into the factors that contribute to the stress response (and our ability to handle it) such as social rank, personality, environment, and genetics. Lastly, we discuss how our behavior is altered in the face of stress and how that not only has a pervasive effect on a personal level, but also on society as a whole in how we interact with each other.
