"Here's your medicine--the instructions for taking it are on the package," said the doctor.
Fred was relieved, knowing that soon he would begin to feel better. "When should I start taking it?" he asked.
Doc grinned and said: "You look pretty good yet. You can wait for a month until you feel much worse."
"What!" said Fred: "Why should I go on being sick for a month? Wait until I feel worse?! I could be dead in a month!"
"Well, OK, how about starting it a week from now?" suggested Doc.
"Hold on a minute!" said Fred. "If this is the medicine I need, why should I wait at all? I want to feel better now! Can I take it now?"
Doc chuckled. "Certainly, begin taking it today. I'm glad to see you know how silly it is to put off taking the proper medicine."
So Fred took the medicine, and it gradually made him worse. Fred nearly died. Then he found out that his doctor was unqualified, and knew very little about illness or medicine. The doc. had got by because his patients had had minor illnesses, and the medicines he had given them had not harmed them. So they had got better despite the medicines.
Fred said: 'I pity the poor suckers who listened that guy, but I'm avoiding him from now on. I was fooled by that quack and not I'm taking any of that SH*T medicine again".
Just a little twist to the story puts a whole new spin on it. The best moral here is: 'don't get sucked in by simplistic allegories'.
