to be in good health. Do you have any medical concerns you would like to
ask me about?’ ‘In fact, I do.’ said the old man. “After I have sex, I

to be fine. Do you have any medical concerns that you would like to
discuss with me?’ The lady replied that she had no questions or
concerns. The doctor then said to her: ‘Your husband had an unusual
