Last night I was teaching this particular move...its called a shoulder twist takedown. The idea is to drop your attacker at your feet. The guy going down has to do a breakfall. In the picture, Jean is throwing me down at his feet. Thats Jean in the red armour, with me on the bottom. The student demonstrated less control than I like, and dropped his right knee onto my ribs. ouch! Imagine if Jean, in the picture below, dropped to his knees on top of me.

I should survive this...its only a cracked rib. But it hurts to laugh. Which cuts dramatically into my fighting since I laugh continuously when I fight. I look on the bright side...he "could" have dropped his whole weight instead of pulling his punch, then I would be in the hospital.
So in the shop today, instead of pounding on steel, I'll be making buckles and cutting leather. Grrrr....
