you like fighting issit? Fighting in sinkieland is largely a joke. Except when too many people and too many parangs get involved. This fight over long before it started. It's obvious the old guy is used to being a bully. Never had anyone stand up to him. It's also possible that he's old/drunk. The young guy also something special, fist against back of head is asking for a swollen hand. Someone else in this thread mentioned knee. That would be good.
Oh... and I wanted to mention. There is one video you posted where I thought MMA would be really useful. Can't remember which one it is now.
I know you didn't ask, but for me, for MMA to work a controlled environment is a must. No bottles, chairs, whatnot. Secondly and very importantly, there must be only 2 and only 2 participants. Thirdly, and equally importantly, rules against foul fighting are a must. Take away these 3 factors and MMA falls apart. MMA works in cage fighting now not because of any planning but because it happened to exploit the rules to the max. Out in the real world, it's a different story.
