I’ve seen a few streetfights in my life, where one of the guys was building muscles in the gym, and the other guy did some martial arts properly. Usually the “bodybuilder” started the brawl, and he was the bigger and the more cocky guy. The outcome was always the same.
If you've seen a few street fights you'll know that they are brutal, pointless, over quite quickly and are sickening. Two people have no chance against a mob of 20 or 30, as was the idea being thrown about.
This is untrue I've see Chuck Norris take down a crew of helicopters while tied up dangling from a sky scrapper wearing nothing but some flip flops.
