yeah i understand you now..... though I don't think one nessaccarily has to "live kung fu" in order to apply that same type of capability (maybe at a much lower level as myself)....but I get what you mean....yes with a simple number of authentic self defense classes one should still be able to bring down a man of such stature unless they are incapable mentally or physically somehow...of applying them properly....
Unless they have a decent amount of training as well. 😬 Manjaro's master was right in a way: all other things being equal, the bigger, stronger fighter will win. But if strength and size was all that mattered, everyone would just lift weights all day.
