Every time I've seen a fight where someone "went for the knees" they were the ones to get their asses kicked.
Real fights don't last as long as the boxing matches you see on television. Sometimes they're over just as quick as they start.
Actually the last guy that went for the knees that I saw, and it was his first attack, missed his uber move and then 1 second later his nose exploded.
Maybe we're having fun with this topic, and making fun of 75 year old people, but Ronith has someone angry at him...If it should come to an actual fight, going for the knees = too weak. All or nothing. If you're going to get your ass handed to you, would you rather have gone for the knees or the jugular?
I guarantee your chances are better if you don't hold back and try to get too specific with what body parts to take out. You limit yourself and open yourself up to much worse attacks by showing what your intents are. I'm guessing Ronith isn't the next Bruce Lee, so he should in fact focus first on his own safety and avoiding this as much as he can, secondly on doing as much damage in as little time should it come to a fight, and thirdly he should have a back up plan...Something to end the fight.
BTW Ronith, have you heard anything more from the freaky geezer?
