If I am well or when I was working my posture is A+. However; its the first thing to give (even before my appetite) if I am tired or getting sick. My shoulders have the curve to them, but not bad yet as a rule. I always remember a girl in school who hunched & she had no respiratory problems, but it annoyed the ***** out of me. I always wanted to go behind her & pull my shoulders back like my Dad use to do.
