Many children love junk food. It's bad for their health. Their parents don't want them to eat too much junk food. Although they know it's not a good habit, they still eat it. Some of them eat this kind of food every day. Some only eat once or twice a week. As a result, they don't have a healthy lifestyle.
Paul is kind of unhealthy. He hardly ever exercises. He eats lots of junk food because he loves it. He doesn't eat fruit and vegetables and he never drinks milk. When he has money, he'll buy junk food. His parents worry about him. They don't want to give him any pocket money any more. But he says, “Maybe I'm not very healthy, but I enjoy myself.”
