I've written before that as I get older (as a male), I appreciate the importance of physical prowess more and more, and definitely infinitely more than I did as a teenager. With regards to taking steps to insulate yourself and particularly your male children from physical bullying (= assault): The first stop should be developing a body and a physical demeanor that naturally makes any bullies think twice about trying to assault you- the perceived cost should outweigh any potential benefit for them. If that fails, and it probably will at some point, because there is always someone bigger and stronger, you need to be proficient in some kind of striking sport. Boxing is great for this. You don't need to be able to go to the final bell with Mayweather, but again, you need to be able to hurt the bully enough that in the future they'll know that the cost will outweigh any potential benefit.
