"Mrs Jones?" asked the voice on the phone.
"Yes. Who is this?"
"It's Doctor Fairfax. I'm afraid there's been a mix-up with your husband's results. He's either got Alzheimer's or Aids."
"Oh my dear God," cried Mrs Jones. "What shall I do?"
"Well," replied the doctor. "I suggest you send your husband out for a walk. If he comes back, don't sleep with him."
