I meant situations where you're at a disadvantage - as I said, doing any kind of martial arts will keep you in shape and will decrease your reaction time (unless you "freeze" in a real situation), but when you don't know how your attacker will move or he's got a weapon in their hands, it's not of much help (not as much as most instructors make it out to be, anyway). And you'd be surprised at how many hits a fat, untrained drunk man can take and dish out, especially once adrenaline kicks in...
