If you knew just how much exercise you'd need to do to burn off that sundae, would you still eat the sundae? Odds are you wouldn't. Well, OK, maybe you wouldn't eat all of it.

A Texas Christian University study recruited 300 young adults and offered them typical fast food fare: hamburgers, chicken sandwiches, French fires, salads, desserts and a choice of sodas or water.

One-third of the participants chose from a menu with no calorie counts; one-third got a menu with calorie counts for each food selection, and the final third got a menu listing how many minutes of brisk walking would be required to burn off each menu item.

The result: There wasn't much difference in the choices made between the first two groups. It didn't really matter whether consumers knew the calorie counts or not. But participants who were informed that it takes, for example, more than an hour of brisk walking just to burn off a 400-calorie burger mostly opted for lighter fare.

BEST MEDICINE

A group of senior citizens were exchanging notes about their ailments.

"My arm is so weak I can hardly hold this coffee cup," said one man.

"Hell, my cataracts are so bad I can't see to pour the coffee," complained another.

"I can't even turn my head because of the arthritis in my neck," opined a third, "and my blood pressure pills make my dizzy."

"Well I guess that's the price we pay for getting old," declared the first man. "On the plus side, at least we can all still drive."
