阅读理解 Physical education, or PE, isn't required for all high school students. In some schools, it isn't offered for different reasons. But should high school students receive physical education? The answer is certainly "Yes." Today many people don't do sports. But as is known to all, doing sports is very important for an adult. Teaching teens the importance of a healthy lifestyle and making fitness plans now can help teens put exercise in the first place as an adult. The American Heart Association says that 10 million kids and teens suffer from being fat. The increase in activities that don't get teens to move around, such as computer games, means many teens don't get their required exercise. PE classes act as a public health measure to encourage physical activities and help teens have healthy weights. Not doing sports increases teens' risk of developing many diseases. An active lifestyle offers a good way of protection from these health problems. As much as 75 percent of health-care spending goes toward treating medical conditions that can be hindered by lifestyle changes, according to the American College of Sports Medicine. According to the President's Council on Fitness, Sports and Nutrition (PCFSN), students who performed five hours of physical activity each week improved their academic performance. Students from programs with no physical activity, who used the extra time for classroom study, did not perform better on tests than those who gave up some study time in support of physical education. （1） What's the meaning of physical education in high school according to Paragraph 2?
