Should physical education be mandatory in schools:
PE should be compulsory because it keeps us constantly fit and healthy. If you really dislike sports, then you can quit it when you're an adult. But when you're a kid, the best thing for you to do is study, play and exercise. If you prefer to be lazy and lie on the couch all day then you are most likely to get sick and unfit. Besides, PE helps kids be better at teamwork.
