An older man was married to a younger woman. After several years of a very
happy marriage ... he had a heart attack.
The doctor advised him to cut out sex to prolong his life.
He went home, and he and his wife discussed the matter at length, and decided
that he should sleep in the family room downstairs, to save them both from
temptation.
One night, after several weeks, he decided that life without sex wasn't worth
living for, and so he headed upstairs.
He met his wife on the staircase and said, "I was coming up to die."
She laughed and replied. "I was coming down to kill you."
