alone are the keys to victory? As well as along with talent of course. This is not say that these two aren't factors because they certainly are factors in a life and death situation. But there are many other more important factors to consider than size and strength alone. I'll bet the guys who think this way watch MMA or fight in it, but against only guys of equal size and not someone stronger, and that some instructors but not all will allow women to train at a low level, and the most powerful weight lifting guys to train at the highest in self defense. Let's face it. There is always someone out there bigger, and stronger than yourself and assuming you two have the same level of talent, the stronger one will have the advantage in a slugging match. In order to beat those enemies on the street, it takes more than being physically fit, and able to take pain. You need skill, patience, smarts, stamina, speed,and most importantly wisdom. A real life and death battle is a whole lot different from UFC matches on TV, as there are no rules, no weight classes, nothing. To put it simply, there is no such thing as a fair fight really.
