A surgeon / barber was asked to close a cut on a thumb. He tried several times before succeeding, ultimately causing much bleeding, distress and scarring. The patient sued, and a panel of medical peers agreed with the plaintiff.
What did the surgeon do wrong, precisely? He failed to take into account the Gemini moon -- and its obvious associated coagulopathy.
Today, malpractice cases would never be decided by pseudoscience like astrology. Instead, we study mistakes and come up with powerful statistics about vocal inflections. Progress!
