Should physical education be mandatory in schools:
Most people think that PE classes are completely useless because the only thing you would normally do in a PE class is run around. But there is more to a PE class then just running around the field for an hour. With physical education you can get muscles, you can become stronger, it wouldn't be so easily for you to become fat (of course you would also need to keep a balanced diet) and for further ages (like 60-80) it would prevent you from having heart attacks. With the help of this class there would be fewer obese children around the globe and more fit and strong people.
