Too bad you weren't able to use your superior intelligence to learn BJJ (there was no way to know which martial arts worked when I was growing up). If he got you down and suddenly his arm was broken and he didn't even see how it happened I bet he would have left you alone.
Very possible, but now the requirement is you have to fight back and win, not just fight back, which is probably asking a bit much in some cases. Some kids that get bullied even have handicaps, so this probably won't work for them.
