the last time I fell that bad was when I injured my back. I was a truck driver and was moving my rear wheels and had a bar that I used to move the lever. it slipped and I went flying backwards about 20 ft bouncing all the way. didn't realize how serious I was injured til the next day. I have to say though I was so embarressed being female and a male driver was right behind me. I didn't even associate the fall with how bad my back hurt til months later. I always wonder when I fall if anyone is watching lol
