Posture is extremely important. No, you don't have to give in to the urge to hunch forward. I had the "good" fortune to undergo a hip replacement a couple of years ago, which made me stand up straight or suffer severe pain. If the tests come out "normal" you might try yoga. It's doing wonders for me. I've just been reminding myself how precious and how short life is--a great motivator for me.
