A health blog I was interested in the piece they had about tai chi in this.

Not surprisingly, an hour of exercise a day helps with sugar control, but they even used it with older folks and discovered that they had better balance when they were done. It reminded me of watching an old boyfriend of mine from college, sweating his way through Tai Chi workouts.

I've been swimming a lot and doing yoga pretty regularly, but there's no way I'm ready for Tai Chi. It requires so much knee bending I think I'd be in perfect and exquisite agony when I got all done.
