Good point Crankin! It is a bit frustrating that I've multiple body parts that some would consider needing surgery, but I think surgery is over-prescribed in some cases. My goal is to stay mobile and functional. If I can't keep that goal without surgery then I may reconsider.
I've yet to find a local TaiChi class that isn't in the middle of my workday. There IS a free class held twice a month at a local church that I want to try out as it's on Saturday - and free - but they seem to always coincide with other commitments. I think October may be the month that I will finally get to go and try it out.
