The strong young man at the construction site was bragging that he could outdo anyone in a feat of strength. He made a special case of making fun of one of the older workmen.

In the doctor's office, the doctor told her that her husband had a very serious disease. He must not have to undergo stress in anyway, the doctor said. You must do all of his chores for him, and make him nice meals 3 times daily.

You must be available for him, and do things with him, such as watch sports games with him. Do not do anything that would cause him to get upset for any reason. Without this kind of special treatment, he will die. You must do this for at least 10 months to a year. At that time he will need another check-up, at which point he will probably be alright again.

Later, on the way home, the farmer asked:"what the doctor tell you?"

She said, "You're going to die."
