I'm a sloucher, big time. I can't even get a good night's sleep unless I curl up into the fetal position. I've tried to sleep straight, face up, toes facing up, and the tip of the nose facing up as well...you know, the dead guy position. Sometimes when I have slight back aches I curse myself for screwing up my back from all the slouching and the abnormal posture I've grown up with. This NY Times Science article , however, contends that notion wrong.
