I used to feel sleepy in class and I couldn’t focus to my lessons. As a result, not only did I do badly in our studies, but also my health went from bad to worse, for that I was often scolded by my parents. I decide to change my situation. Half a year ago, followed my teacher’s advice, I began to join some sports activities. I now play the basketball for 45 minutes every day. My health has improved, but at the same time, I’ve made lots of progresses in my studies. Physical exercise has changed me into an entire new person.
