Dr. Sanjay Gupta is the first three-peat Armchair Expert guest and an American neurosurgeon, medical reporter, CNN medical correspondent, and author. Sanjay, fresh off receiving his covid-19 vaccination, joins the Armchair Expert to discuss how much we've learned this year about human behavior. Sanjay explains the evolution of neurogenesis and why cognitive decline is not inevitable. The two discuss that in order to heal the body you have to heal the mind, the importance of building the resiliency of your brain, and the power exercise has on it. Dax tells Sanjay about Monica's psilocybin experience and Sanjay tells us that the best thing you can do for your brain is to take a brisk walk with a friend and discuss your problems.
