At the tai chi class yesterday we finished learning the whole set! I still feel kind of awkward, and I don't entirely know what to do with my hands for all the moves, but the feet are good. And, the best thing, is that even though I'm currently suffering through a full right-side attack of knee/wrist/elbow swelling and pain, I still managed to do an hour and a half class, and don't feel any the worse for it today.
