Brings back lots of memories, though I never tested for belt rank that required breaking a board or blocks. I use to wonder after all these years if it would come back intuitively, about ten years ago I was coming across a pedestrian bridge downtown from a lecture at a convention hall when I heard something behind me, when I started crossing I was alone so it startled me but instinctively as I turned my head as soon as I seen something move out of the corner of my eye my body instinctively started to position for a back kick and a couple years ago my son's girlfriend was mad about something I said to her, she came forward like she was going to slap me and I instinctively positioned into a side stance. I think it startled her that I moved into a defensive position mode and she backed off. Prior to all that there was a time my kid was arguing with a girl who stole money from them, I told him to come on and leave the trash alone, she said I should come down there and beat your ass, I told her I'd like to see her try...she did too, she came down and had someone twice her age kick her butt. My son bragged about that for days. Now though I always carry my spray I protect my dog with from other dogs, getting up there a bit, it'd be just a whole lot easier to mace them.
