Please, if you want to learn about real life, go to street fighting forums. read about Geoff Thompson, "Awesome" John Anderson, talk to some bouncers, hell talk to guys who just got out of prison. Look at all the baddest mofos out there, the homeless or gangbanging teenagers, the petty crooks, youll never see them lifting weights, taking protein supplements, washing their gi or breaking boards. If they do any martial arts, its almost always boxing. There usually wiry, lanky and tall. If they are big, its natural, mostly fat. None of this bodybuilding sh!t.
You dont want to end up on the ground. bad sh!t can happen from there, and its hard to run away. You have to be willing and able to choke the guy out or break some bones, none of this 'tap' bull****. You let the guy go and he'll keep going, this time knowing not to go to the ground. he'll probably say 'ok you won' and offer to shake your hand or pretend to be buddies, and then sucker punch or headbutt you.
Remmeber that while your applying your advanced jiu jtisu he'll be biting, clawing, spitting, etc.
assuming there are no weapons and its a 1v1 fight: headbutt, punch on the jaw or throat, knees. Hit first and hit hard, keep hitting on the jaw until hes KOed, or if he's a better fighter than you, run away as soon as possible.
if there are weapons or multiple opponents: run away
street fighters are better fighters than martial artists. if you insist on training martial arts: the pure punch of a boxer (mostly right hand followed by left hook), knees and low-kicks of muay thai, crash course in wrestling or judo, focusing on the upper body, and focusing on throws where you falls to the ground, but you stay on your feet.
