Some self defence is a good thing.
Yes, it is. The Lovely Wife has been studying Okinawan karate (the Okinawans later taught karate to the Japanese.......but ONLY what they taught their own kids so they wouldn't hurt each other because they mistrusted the Japanese....true story) for about three years now. It isn't flashy, no high kicks, damned efficient, damned deadly. I pity the poor bastard who'd assault that 6' former farm girl (and also my weight lifting partner). I truly do.
