This is an excellent post, but a lot has to do with mental preparation.I am 33 years, and sadly have been in some bad situations. The only issue with looking to police and bouncers for advice is they live in a very different world. When one of these professionals gets into a situation the attacker knows he has a challenge. For the average person, assuming it is an attack and not a bar fight, the attacker is not expecting a problem. That is why he chose you. You have the element of surprise, and as long as you do respond, your skills should come out.
