How to Develop Good Living Habits
Everyone has different living habits. Good habits can make us keep healthy. As teenagers, what should we do?
In my opinion, everyone should get up and go to sleep on time every day. Dont play computer games or watch TV all night. That is bad for our health and affects our work. We should eat more vegetables and fruit, and eat less meat. I advise everybody to take more exercise. Dont eat junk food. Dont litter or spit around. Dont play on the road. Remember to obey the traffic rules. Dont cross the road when the traffic light is red.
In a word, if we want to keep healthy and happy , we must develop good living habits.
