I train FMA for self defense with the number two guy in our system. He is a Filipino-American, former US Marine, former power lifter, deadly with his hands, deadlier with a knife, and he always carries a sidearm...even when training. Fortunately, he's also really good natured! So here's the deal. He's got the self defense thing pretty well covered. But he's become a freakin' chain smoker. Maybe he doesn't have to worry about thieves, muggers and wacked-out druggies... but those little white sticks are gonna get him sooner or later. Any thoughts?
