Children, children...... yes, we old farts have to be a tad more careful. I'm forty two, with 23 years of training [abuse?] and probably worse, 14 years of infantry, which is where my injuries come from- buggered knees and ankles from landing too hard from the back of trucks and choppers. [Try fast roping with a 40lb pack and an M60- you don't bounce!]. I was always a kicker, though I'm big and heavy. My flex is not affected but on a bad day I can't contact anything without damaging myself. I've been turning to hands/grapples/throws more. I also managed to get gout. Yes friends, the rich and decadent disease [I was real clever but- I bypassed the wealth and went straight to the disease!]. That gave me a taste of how helpless you can become. I'm cured now but for around five years fast tai sabaki was out. I had to grab and hold on. Old age is a fiend but I still got me trusty chen Musashi!!!
Lurking in dark alleys may be hazardous to other peoples health........
