I move a lot. My posture in general is terrible. I'm slouched in the corner of a couch right now, with my laptop on a half-lap, and when I worked in an office I would usually drape myself over the back of a high-backed chair and kneel on it. However, I don't stay in any one position for longer than about 15 minutes - after that I stand up, or shift to a different position, or swivel the chair around, or go lie down. Never had back pain or other joint problems other than tendonitis in my fingers. I've found that moving around and standing up every 15 minutes or so outweighs all the other shitty stuff I do to my body. Humans weren't made to sit still.
