An elderly couple, still very loving after all these years, is shocked when the woman's doctor says she has a heart condition that could kill her at any time. She is to avoid stress, eat right, and never, ever have sex again -- the strain would be too much. The couple reluctantly try to live by these rules. Both get really desperate over time, however, and the husband decides he'd better sleep down- stairs on the couch to guard against temptation. This works for a few weeks, until late one night when they meet each other on the stairs--she's coming downstairs, he's heading up. "Honey, I have a confession to make," the woman says, her voice quavering. "I was about to commit suicide." "I'm glad to hear it, sweetie," the man says, "Because I was just coming upstairs to kill you!"
