Can teaching martial arts actually reduce violence? In this episode, Jeff talks with Brazilian jiu-jitsu master teachers Ryron and Rener Gracie about the wide-reaching benefits of jiu-jitsu, including how police training in this technique helps them better de-escalate conflict and reduce excessive force. They also discuss jiu-jitsu as a form of meditation and method for instilling reason and rationality in the human brain during moments of extreme tension.
