Some students get up late; others prefer to stay in bed for a few more minutes. That's why many of them just skip breakfast. It’s very bad for health. In the morning students usually have four classes. It’s a long time before lunch. If they don’t eat anything for breakfast, they may feel hungry and they can’t listen to the teacher carefully. Study shows that people who do not have breakfast think slowly that day. Besides, teenagers need extra energy when they are growing. Therefore, having a good breakfast is very important for students.
