Two colleagues, Bill and Mary, are having lunch in their office cafeteria.

Mary: I can't believe my eyes, Bill. Are you having a salad for lunch? No hamburger?

Bill: Get used to it, Mary. I'm off burgers for good. Most fast food is loaded with sodium.

Mary: I know. But why your sudden interest in lessening your salt intake?

Bill: My doctor says I should cut back on sodium-rich foods to lower my blood pressure.

Mary: Do you have hypertension? I would have thought you were too young.

Bill: Actually, my blood pressure isn't that high yet, but they say it increases with age.

Mary: Well, I'm glad you're starting to pay more attention to your diet.

Bill: I want to lower my risk of heart attack and stroke, too.

Mary: So do I. That's why I've been trying to lower my cholesterol level.

Bill: I've noticed you've been munching4 away on lots of fruits and vegetables recently.

Mary: That's right. I could stand to lose a few pounds, too.

Bill: In that case, you should come to my health club with me.

Mary: You've joined a health club? I would never have dreamed that you'd take something like this so seriously.

Bill: So, how about it? Can you tear yourself away from the TV tonight?

Mary: Why not? If you can break your unhealthy eating habits, I can surely break a sweat.
