The story was inspired by a typical scene in a typical Hollywood film. A man and a woman are running away from a killer. The woman is wearing high heels, tripping over and falling. Instead of jumping up and running, she is reaching out her hand. The man is grabbing it, and she is suddenly able to get up and run again. I know several women personally and every one of them can get up and run unaided, particularly when being chased by a killer robot, a hungry dinosaur, or a psychotic assassin.
