I have horrible posture, in fact, I can't stand up straight properly without alot of pain. I think it might be from growing up with massive depression making me slouch alot and stare at the ground.

Oh, one thing I learned when I went to physical therapy for my back, if you want good posture, work on your stomach muscles cause those help support your back and help you stand/sit up straighter.

Ooooh and the ball is a good idea. I might have to try that since I never thought about it!
