Matt Polly was 36 and overweight, his days as a student of Chinese kickboxing long past. On the precipice of middle age, he took one last shot at glory. He plunged into the bruising sport of mixed martial arts, trained with the pros and eventually tested his skills in an amateur bout, as detailed in his book Tapped Out: An Odyssey in Mixed Martial Arts. Matt and I had a very entertaining conversation about his experiences and about the world of MMA. Matt explains that contrary to its reputation for primal thuggery, MMA is a highly technical sport and even an art.
