I still sit that way on the couch but not sewing or at the computer anymore. I have alot of back pain as it is and that makes it worse. However for many many years I sit with my left foot under me and my mother used to tell me that it was going to injure my knee. Well guess what? Its my right knee I have alot of trouble with. :lol: I think sitting on my with my left knee bent for years kept it stretched and flexible and its fine. :wink:
