I always keep a tazer on me. Not for self defense, as I'd be more effective using my fists and the knives I keep taped to them, but so that I can literally jolt myself into action at a moment's notice.
Think about it. Do you want to enter a fight unprepared? No! So go shock yourself with a tazer BEFORE it starts.
It's like an activator for my fight response. A button I can push at any time for free adrenaline. When I walk into the DMV I'll give myself a quick jolt to assert dominance over the office clerks. I'm just too powerful, able to summon a breserker rage at the drop of a dine. Man was never meant to wield such power. Sometimes I set it on a timer to keep me on my toes.
