W: I can’t believe my eyes, Bill. Are you having a salad for lunch? No hamburger?
M: Get used to it, Susan. I’m off burgers for good.(9)Most fast food is loaded with Na—a kind of chemical substance. I’ve been reading about a new healthful snack food. It’s made from fish. Have you heard anything about it?
W: No, I haven’t. But I don’t like fish very much anyway. But why are you interested in lessening your salt intake?
M:(10)My doctor says I should cut back on Na-rich foods to lower my blood pressure. Actually, my blood pressure isn’t that high yet, but they say it increases with age.
W: I would have thought you were too young for that. Well, I’m glad you’re starting to pay more attention to your diet.
M: I’ve been eating lots of fruits and vegetables recently. I want to lower my risk of heart attack and stroke, too. Recently, my family are trying to eat more healthy food.
W: So do I. That’s why I’ve been trying to lower my cholesterol level. Just like you, I’m now trying to lose a few pounds, too.
M: In that case,(11)you should come to my health club with me. Can you tear yourself away from the TV tonight?
W: You’ve joined a health club? I would never have dreamed that you’d take something like this so seriously. (11)Why not? If you can break your unhealthy eating habits, I can surely break a sweat.
M: I can do 100 push-ups in a row. Don’t get jealous. You will do it someday.
