Over the weekend, I sparred a classmate of mine who is 12 years younger than me at age 38. Until recently, I have been known for my kicks and foot movement. Now, at age 50, and after knee surgery, shoulder surgery, hernia surgery, and Chron's, I am still in relatively good shape for my ager but after almost 32 years of training/practice I can feel it...LOL! I took up Yang tai chi 12 years ago to change things, including my disposition from an angry kung fu guy to a pleasant tai chi killing me softly guy....LOL! In any event, to other people of my generation, how has your practice changed in the last few years, both mentally and physically, as you age? What different kinds of practice have you instituted to keep up your skills yet not beat up the body so much anymore? I am just curious and ask advice from my fellow old codgers here. I accept the fact that you answering me in no way implies you are now an old codger....LOL! If you are young codger, will take advice as well. Gotta go get my hearing checked now, look forward to everyone's advice!
