When I was around seven years old, the local tough guy kid took an extreme dislike to me. I was doing my best to avoid meeting him on neighbourhood streets, for fear of being beaten up. At around that time, I read a book about a kid in a similar situation. The author wrote: "I held my breath and hoped that he didn't recognize me." For a long time afterward, I believed that holding your breath changed your appearance.
