A: Hi, how’s everything?
B: Not so good. I went to the doctor for a check up, and he told me I have to eat better and exercise more.
A: It’s important to eat well. Do you eat lots of salads or vegetables?
B: I sometimes eat salads, but not often. However, I eat vegetables almost everyday. Potato chips are made from potatoes; that’s a vegetable, right?
A: That’s not very healthy. Do you take vitamins?
B: I have vitamins at home and I take them off and on, but I often forget.
B: I drink it once in a while, but I prefer coffee. Is that healthy?
A: It’s not very nutritious. Maybe you should exercise. It’s good to be active. How often do you exercise now?
B: I never go to a gym. It’s too expensive.
A: Okay, how about running or jogging? How often do you jog?
B: I occasionally run to catch the bus, but not often, maybe once a month.
A: I see. How about walking? How often do you go for a brisk walk?
B: I go for a leisurely walk after dinner when the mood strikes me, maybe twice a month, but I almost never take a long, brisk walk. I have no time.
A: I see. How about swimming? It’s good for you. Do you swim?
B: I used to swim all the time, but now I seldom go swimming, maybe once a year if friends with a pool invite me.
A: How about push-ups or aerobics at home? Do you do that sometimes?
B: Every year, I tell myself to start, but I only do it once in a blue moon, when my jeans get too small, maybe every six months. I use a hula hoop.
A: How about housework? That’s good exercise, too.
B: I clean my house now and then, maybe once a month!
