While traveling in another country, Jack felt unwell and went to the local emergency room.  There the doctor told him he needed a triple bypass and should replace an aortic valve.  “Never fear,” said the doctor, “we have the latest robotic surgery equipment; in fact,  here, let me take you to see an operation in progress from the balcony in the operating room.”  After a few minutes, Jack elected to wait until he returned home for a second opinion and further treatment. . . . .  David, Sf.G.
