I talk with clinical psychologist and BJJ black belt David Ley about the psychology of jiu-jitsu, recent advances in psychology, the neurochemicals released when grappling, recovered memories, the prevalence of conspiracy theories in the martial arts, and much more. If you want to focus on the jiu-jitsu specific portion of the podcast listen to the intro then jump to the 45 minute mark.  Dr David Ley is a clinical psychologist who runs a large mental health clinic in Albuquerque, New Mexico, and has been featured on the Anderson Cooper Show, the Dr. Phil Show, in the London Telegraph, The New York Post, Salon, and the Huffington Post. He wrote The Myth of Sex Addiction (Rowman & Littlefield, 2012), and Insatiable Wives: Women Who Stray and the Men Who Love Them (Rowman& Littlefield, 2009).
