I would spend the most of my PE lesson to exercise rather than study in class.
There are various activities, such as playing table tennis, playing football and so on.
While, I just love running, especially the long-distance running for it exercises my endurance and perseverance.
Not only it is beneficial to prevent and cure diseases, but it can alleviate my pressure from study.
So, every time I have difficulty in my study, I always run on the playground for relax.
Then I would feel better and focus on my study again.
