Most people I know who study fighting are those that don't like it. I don't like fighting, but I also don't like being subject to the whims of people larger than myself - which is most everyone. I know all too well how you are treated when you cannot defend yourself, and do not intend to be in that predicament ever again. What protects us, laws? This country as a whole isn't even concerned with international law - and internally things are worse.

Well, it turns out to be incredible exercise too, but that's not what inspires most people that I know of.
