Sports clases in secondary school. Education is a topic who always stays under discussion. This could be good, because we are in continuous reflection, which can help us to improve certain aspects. One of the topic of discussion are the existence of physical education classes in high school. Firstly, we can find people who think that P.E. in this ages it is a waste of time, insomuch as this teenager need to concentrate on their academic subjects. Subjects that could really help them in their future. On the other hand, there is another group who believe that the physical activity has a lot of benefit in the young life. Several studies have linked the ability to concentrate better after exercise, and have better rest at night. Even it said that after practicing a sport you feel more active to do other things. In my opinion, exercise also can help us release stress or nerves and thus feel more relaxed. Without forgetting the benefits it has for our overall health and knowledge of our body that this has. For these reasons, I defend the practice of this subject in high school. Enjoy sport, but do not forget, practice fair play!
