Maybe all the people sitting in front of computers all day know this already, but “according to this article”:http://www.sciencedaily.com/releases/2006/11/061127112844.htm, sitting straight up is not the best posture for your back. They use a new kind of MRI to show that actually leaning back 45 degrees is better than sitting up straight. Slouching forward is apparently the worse.
I have a pretty bad slouch. Maybe I should sue that Saturday school teacher that always scolded us about our posture.
