Another aspect of sport Jujitsu that I really enjoy is that it is a sport. So much of martial arts training focuses on the what ifs. We always seem to preparing for some do or die fight that isn't going to happen. And preparing for it through the memorization of set patterns quite probably isn't going to help you much even if it does happen. Jujitsu should not be about fighting.
Real fights are ugly, clumsy and generally only willingly engaged in by idiots.
Personally I do not fight. This book is neither about how to look good in a fight, how to win a fight or where to find the best fights. Instead of concentrating on fights I'd rather focus on the sport which is far more fun and if need be, more effective then training for combat. One manifestation of sport Jujitsu was the off shoot Judo . There is some weakness in Jujitsu, both sport and non-sport.
