An 86-year old man went to his doctor for his quarterly check-up.

His wife of 65 years went with him. The doctor gave him the full work-up, put him on the treadmill, X-rays, MRI, etc. When the physical was done, the three met in the doctor's office, and the doctor said to the man, "Everything's looking good. Could you excuse us for a minute so I can have a word with your wife?" The man left and waited outside.

The doctor turned to the wife and said, "Your husband is suffering from a very delicate medical condition, and it's up to you to save him. In order for him to recover, it's vitally important that he be kept as comfortable as possible, that you serve him the best, most delicious meals, that you not tax him with any extra work around the house, and that you give him as much sex as he wants, whenever and however he wants it."

As the couple drove away from the parking garage at the medical office, the wife was behind the wheel. The man was understandably anxious to hear from his wife. "Well, what did he say? What did he say?" he asked excitedly.

She turned to him and said: "You're going to die."
