My wife had an accident today when the stepladder she was at the top of (with her head up inside our attic) skidded out from under her, and she crashed to the landing floor 8 feet below. I didn't expect to be doing first aid today, but I'm glad I was there to help, and apart from cuts, bruises, and two sprains, she's not too badly damaged.
Mind, she's one bad tempered fucker when she's hurt.
