Ali: Good evening.
Bassy: Good evening. Where were you going in the morning?
Ali: I was going to see the doctor.
Bassy: In what connection?
Ali: I have not been feeling well lately.
Bassy: What's the matter?
Ali: I have been having a severe headache.
Bassy: Do you have exercises?
Ali: No. I don't have time. I am busy with my studies. I have to study all the time.
Bassy: That's why you are not feeling well.
Ali: What do you mean?
Bassy: I mean, a person who studies the whole day and does  exercise his body, he is likely fall ill.
Ali: I still don't get you.
Bassy: Listen. Exercises are very important. When Exams are near, students tend to study the whole day sitting at one place. They suffer from food indigestion. Thus they get sick.
Ali: You may be right.
Bassy: Not may be but I am. Seems like you don't know the importance of exercising your body.
Ali: What should I do then?
Bassy: Exercise regularly either in the morning or in the evening. But in the morning it's better.
Ali: You will get well without a doctor in no time.
Bassy: I will give it a try tomorrow.
Ali: Sure. There is no harm in trying. Good bye.
Bassy: Good bye. 
Ali's not been feeling well recently. He has no time for exercises because he's been studying all the time. Bassy advised him to do exercises on regular basis to feel better.
