Third one must be old hat, huh? [He's like this. Don't mind him.] I should warn you that if you ask me about either, you're getting into one hell of a deep explanation that crosses the lines of philosophy, ontology, spirituality, and asskickery. Usually when I start off, I say 'everything is martial arts' and that's when people roll their eyes at me and tune out. Fondly, sometimes, to be fair!
