"Sounds to me one needs to be a little more than just being aware of his surrounding."
not at all, it depends on your natural level of awareness. you see guys walking around with a coffee mug in hand and stereo headphones on, may as well have their fingers up their arse. I am always aware even in crowds, if you have that kind of mindset it takes a lot to surprise you.
As tp hurting people etc.i notice that people will say that /I am very aggressive when I am not, I am just very assertive.....for example a bitchslap looks very violent when it is just decisive............when you move quickly and decisively, cut away all the fluff and bubbles, no silly stances or set ways of moving your hands e.g. hands held at the hip.then to people who don't move like this you do look violent.but it's them who are doing it wrong
