"Shit! What am I going to do then?" he worried.
"Well, I have an better plan. One that I call the 'organic' approach. What you do is fuck your wife five times a day, every day. It will really tell on her. Eventually, you will have fucked her literally to death."
This plan appealed to the man for several reasons, so he agreed to implement it.
Five weeks passed, and the doctor hadn't heard a word from his friend. Curious about his fiendish plot, he went to the friend's house to check on its success. There in a rocking chair on the front porch sat a wizened old coot who was wrinkled, stooped, gray, balding, dehydrated, and his teeth were all falling out. The doctor was shocked when, upon closer examination, he realized that this old wreck was really his friend/patient.
While the stunned look was still on the doctor's face, the wife walked out the front door and smiled at him in leaving the house.
"My God! She looks flush, radiant, and vibrant!"
"Yep," wheezed the husband, "she doesn't even realize she's about to die!"
