Getting My Chi in Order

I joined a tai chi class that meets in the recreation center in my neighborhood. I had taken a few classes with momlls last year - just long enough to figure out that it's harder than it looks. Walking around the city parks and sidewalks I've seen people over 80 doing their exercise and they look so graceful. One old fellow was doing dips and splits so low to the ground I couldn't believe it. It looked like he was doing the limbo and playing basketball at the same time. Right now my goal is to stand on one leg without falling over.
