My name is Lily.I'm a 15-year-old girl and I'm very healthy. However, one year ago,I fell ill often I loved chocolate and chips very much. One morning, I saw some young men doing exercise in the gym. They looked really fit and active, so I stared exercising. Now,I spend half an hour doing exercise in the gym every day, and I'm good at running. I drink milk and eat fresh fruit and vegetables instead of chocolate and chips. Healthy eating habits and exercising help to build me up. I'm going to take part in the running in our school sports meet. I'm sure to win the game.
