I've decided to take up the martial art of tai chi. There are so many benefits to this... from lowering blood pressure and sharpening the mind to reducing stress and increasing flexibility! Plus when I get to Beijing, I'll be able to join a group of people in a park somewhere... great way to make friends or will people think that I'm just a crazy American trying to fit in? Whatever the outcome, I think that I've finally found a way to workout without straining my already scarred knees. :) I'm so excited!!
