Watch your posture. Stand straight. Don't bend OVER to pick up things, bend at the knees. Carry a small cushion to put in the small of your back when sitting or driving. Cut back on your driving - do as little as possible and ALWAYS put that cushion in the small of your back. If you have to go on a long drive, get out and stretch your legs often and change the position of your seat now and then.
