Hey doc,I was just wondering what you think of yoga. About 5 years ago I dislocated my shoulder playing volley ball (which I loved!!!) and had to stop playing because the injurie was so bad. It also makes swimming scary, not to mention difficult because I could reinjure myself. In the last couple of years I've developed arthritis, particularly in my knees, so high impact things like running are painful. I've heard that a big part of yoga is controlled breathing so I thought it could be good for the ol' lungs. What do you think?
