I think you'll like this one: in this episode I speak with Ando Mierzwa (Sensei Ando) who is a black belt in Tae Kwon Do and Kung Fu San Soo with extensive experience in BJJ, Aikido, and Shotokan Karate.  We talk about levels of realism in training, tribalism in the martial arts, the fighting arts as a tool to feel some control in a chaotic universe and much more.  Ando's website is http://www.senseiando.com and you can also follow him on Youtube at https://www.youtube.com/user/AndoMierzwa/videos
