I am not much of a swimmer. Swimming pools used to give me a headache so I avoided them and the local streams were full of leeches so I tried to stay on dry land as much as possible. My wife loved to swim and used to do so competitively. She won several races for her high school team. She tried to get me to go swimming with her and every once in a while I would humour her and splash around in the pool for an hour. One day she challenged me to a race. I won very handily. She has since lost her enthusiasm for swimming.
