Composition Revision- An Interesting Sport

I am interested in sports and I have entered many competitions. However, after getting
involved in various sports, I discover that playing volleyball is a fun and suitable activity for most people. Above all, there are many advantages of playing volleyball, such as keeping fit, relieving tension and making more friends.
According to some surveys, many people play volleyball to stay healthy. When they play volleyball, they have to focus on the ball all the time and they cannot let the ball fall onto the ground. Therefore, they must move their steps frequently to catch the ball and make correct judgments whether the ball is in or out.As a result, after joining a volleyball game, they always sweat heavily and it is healthy for them because sweating is good for metabolism. Moreover, their reactions become quicker due to playing volleyball regularly. For instance, Cathy was my classmate and she often got sick. Once I asked her to play volleyball with me and then she agreed. Afterwards, she played volleyball constantly and that made her react more quickly than before. Now, she is healthier and she relies on playing volleyball to keep healthy.
Most people relieve tension by listening to music, running or going shopping, but I am different from them. If I am under pressure, I play volleyball with my friends to alleviate it. When playing volleyball, I concentrate on the ball and those tiresome things go away from me. It keeps me calm. Furthermore, while playing volleyball, my whole body gets stretched and I feel relaxed and comfortable. For example, my sister applied for a job and she would have an interview the next day.She was nervous and worried because she was afraid that she could not do it well.At that time, I suggested she play volleyball to calm her down. So she did it. The next day, she told me that it was useful. After that, whenever she wants to relieve her tension, the only place she will go to is the volleyball court.
The third advantage of playing volleyball is that I can make more friends. Because volleyball is not an individual sport, it is a team sport. What is more, when entering a competition, my partners and I have to cooperate to defeat the competitors. Therefore, the relationship between us will be closer and better. To illustrate, when Joy was a freshman, she liked to play volleyball. Originally, she was often alone because she did not know anyone in the volleyball court. After a few days, she decided to ask some girls whether she could join them. Unhesitatingly, they agreed gladly. By and by she knew many people and made good friends who shared the same interests . More importantly, because of so many friends, she learned more and they broadened her horizons.
Playing volleyball has many advantages and many people depend on it to keep healthy, to relieve tension and to make more friends. Nevertheless, if people want to experience these advantages, they should play volleyball regularly instead of just playing it in a short term. In addition, if they do it seriously, maybe they will find more merits of playing volleyball. In particular, volleyball is not only a sport but also a interesting group activity people can learn much from.
