Nick is a 14-year-old school boy. His life is full of exams and studies on weekdays. He has little free time. He thinks playing computer games is the best way to make him relax. When he has free time, he sits in front of the computer. Just like that way, he neither eats nor drinks for several hours.

Last weekend, he played games on the computer again. He was too excited and didn’t want to move. He didn’t have anything for six hours. When he had to go to the bathroom, he found he could not move. He was taken to the hospital. The doctor told him he should do some more different kinds of activities. In other words, he needs more exercise and outdoor activities to make him have a healthy body.

After coming back from the hospital, Nick follows the doctor’s advice. He often plays soccer with his friends. Sometimes he still plays computer games on weekends, but he never does it for long. Now, he lives a happy and healthy life.
