See the thing is you THINK it's not a problem for yourself because you have never encountered somebody that truly attempts to hurt you and knows how to do so, maybe that's because you are a large fella or just very confident due to never being hit with a dose of reality. It's a false sense of security regardless, I hope you never do find yourself in that kind of situation because you will be in for a big wakeup call and may be the one that ends up with the brain damage. let's hope there is somebody else around that knows how to fight that can protect you. No disrespect at all either if you want to disrespect others by calling them brain dead that's your right and I'm sure you only ever do it from the safety of your computer chair at home hence the false sense of security.
