Gosh, Southblues: That's exactly what I had to tell my (new) primary today; that I didn't have a clue how I fell. Just went flat, with no attempt to catch myself, fling my arms out, nothing. It doesn't help that I literally have to stare at the ground when I'm walking, 'cause just about anything can throw me. I guess I'm glad to hear that I'm not the only one. Although I haven't fallen down an entire flight of stairs...yet...boy, I can sure empathize. Gives me a mental picture that makes me shudder. Be darn careful on those stairs!
