His doctor prescribed some pills, but they didn’t help.On his next visit the doctor gave him a shot, but that didn’t do any good.On his third visit the doctor told the man to go home and take a hotbath. As soon as he was finished bathing he was to throw open all thewindows and stand in the draft.”But doc,” protested the patient, “if I do that, I’ll get pneumonia.””I know,” said his physician. “I can cure pneumonia.”
