What a great post. I agree thoroughly.
Before I got as old and fat as I am, I studied both taekwondo and hapkido. I never could kick to the head, but my TKD instructor was great at incorporating techniques from many different disciplines. Hapkido by its nature incorporates joint locks and takedowns. When my hapkido master asked why I wanted to learn, I said because if someone tried to attack me, I wanted to disable him long enough to draw my gun and my cell phone.
I also took Insights Training's "Unarmed Self Defense" course. Excellent weekend.
