Alex: I feel so tired all the time. I don't have any energy. What should I do?
Faisal: Do you get eight hours of sleep every night?
Alex: Yes, I do. In fact, I usually sleep longer than that!
Faisal: Well, you could get more exercise.
Alex: Like what?
Faisal: You could work out at the gym.
Alex: But I don't have time. I'm too busy.
Faisal: Really? How do you get to work in the morning?
Alex: I drive my car, of course.
Faisal: Why?! It's only a mile to your office. You should walk or ride a bike.
