My straw was my knees. Doing nothing more vigorous than descending stairs too quickly, I severely injured my left knee and mildly injured my right knee. It's taken a year and a half to rehab them to the point where they don't hurt when I walk. 300+ pounds is just too much weight for any 5'3" gal to be able to carry, and not expect knee troubles. For 25 years (since my 30s) I've been happy as a fat woman, but now it's time to change!
