HEALTH FACTS
Humor has been shown to boost brain-power and improve immune-cell function (which can help ward off cancer). Not only that, but a positive attitude means you're more likely to do healthy things like walk, eat cruciferous vegetables and avoid saturated fats­--three choices that substantially help the chance of survival after a heart attack, stroke or cancer. So instead of feeling blue, take charge of your life.

Humor therapy could one day be a part of preventive care. A good giggle helps you:
Scorch calories - Laughing for 10 to 15 minutes increases your heart rate by 10% to 20%, which means you can burn an extra 10 to 40 calories a day. Over a year, that can add up to a four-pound weight loss.
Ease pain - In a UCLA study funded by Rx Laughter, a group that promotes research on the connection between humor and health, experts discovered that children tolerated pain better than usual when watching a funny program or video.
Stay healthy - Humor increases the production and effectiveness of natural killer cells that stomp out germs. These cells are elevated for at least 12 hours after just an hour of watching...Will Ferrell....

JOKES

1. A husband feared his wife wasn't hearing as well as she used to, and he thought she might need a hearing aid. Not quite sure how to approach her, he called the family doctor to discuss the problem. The doctor told him there is a simple informal test the husband could perform to give the doctor a better idea about her hearing loss.
"Here's what you do," said the Doctor. "Stand about 40 feet away from her and in a normal conversational speaking tone, see if she hears you. If not, go to 30 feet, then 20 feet, and so on until you get a response."
That evening, the wife is in the kitchen cooking dinner, and the husband was in the den. He says to himself, "I'm about 40 feet away, let's see what happens." Then in a normal tone he asks, "Honey, what's for dinner?"
No response.
So the husband moves closer to the kitchen, about 30 feet from his wife and repeats, "Honey, what's for dinner?"
Still no response.
Next he moves into the dining room where he is about 20 feet from his wife and asks, "Honey, what's for dinner?"
Again he gets no response.
So, he walks up to the kitchen door, about 10 feet away. "Honey, what's for dinner?"
Again there is no response.
So he walks right up behind her. "Honey, what's for dinner? "
"Ralph, for the FIFTH time, CHICKEN!"
