John is a 13-years-old schoolboy. He studies very hard at school and gets good grades in all his subject. But he doesn't like sports. Six months ago, he did not feel good. He often had colds and felt sick to his stomach. His parents took him to see a doctor. After asking him some questions and giving him a careful examination, the doctor said which it was not serious and told John's parents ^ to worry about it. Then the doctor told John to take more exercise and stop eating fast food. From then on, John went to school by a bike every day instead of taking the bus. At first, he felt tire and weak. But two weeks later, he got fitter and started to enjoy it. Since he started ride a bike, he has not had a cold. To his surprise, he has not had a stomachache since he stoped eating fast food.
