A couple months ago my husband was on the back drop hatch of a one ton pick up truck standing side too and trying to pull something out of a pile of junk in the truck, well what he was pulling came loose and he went off the end of the truck, and amazingly landed on his legs but immediately went down sideways onto the sidewalk on his side.
I was amazed he did not break anything or even end up with serious bruising! He has had several falls though he always finds something to blame them on. He teeters and totters when walking or climbing stairs and tends to fall backward more than frontward. One night a few months back I was asleep and heard a big crash right next to my side of the bed. He was going to the bathroom and got as far as the door to the bedroom and legs went out and he fell completely backward to the floor right next to my bed, missed the bed rail holding up the mattress by less than in inch from his head.
He does have a cane, when he remembers to use it, I worry about him all the time.
