Most Whovians know that The Doctor is not a fictional BBC television character. He is a real life Time Lord from the planet Gallifreyan. The evidence is indisputable. Numerous photos and artwork show his presence throughout recorded human history. Seven thousand year-old Palaeolithic rock art found in the cave systems of Western Europe clearly showed the carved image of the TARDIS. There was a man in Verona, Italy who went to the emergency room with near death injuries. They first recorded that he had unusually low blood pressure. The emergency room doctors see similar symptoms all the time, but this man was very different. He had two hearts. He left the hospital before they could do more tests.
