So, if I'm no cheerleader of sports, why write a chapter about it? Sports do have some positive impact on society. They solve problems, such as how to get inner-city kids to spend $175 on shoes. They serve as a backdrop for some of our most memorable commercials. And they remain the one and only relevant application of math. Not only that, but we have sports to thank for most of the last century's advances in manliness. The system starts in school, where gym class separates the men from the boys. Then those men are taught to be winners, or at least, losers that hate themselves.
