    My dad is an enthusiastic runner. Influencing by him, I was very sporty before the age of 15. Therefore, after I went to high school, I stopped to taking physical exercise because of my busy schoolwork. One morning, I ran for only one minute to catch a bus, but I was quite out breath. This made me realizing that I was overweight. Then I made a decision which I would take up a sport to help myself get in shape again. A friend of me recommended(推荐) a swimming pool not far away from my house. Now I go swimming several times one week and have started to feel the benefit of regularly exercise. Swimming makes me relaxed and energy.
