Dad has problems with falling, although he usually does it when going backward or sideways. He can usually roll himself into a ball, like when a gymnast does a somersault. This protects his head, but his back and hips really get it hard. I think that one of the first things they teach you in martial arts classes is the "art" of falling. Maybe a physical therapist would also be able to teach you to fall so that you don't hurt yourself. Trish
