Pharaoh Tutankhamen had curvature of the spine, a bizarre elongated head, a cleft palate, and a hideous overbite. He also suffered from mental retardation, a result of his incestuous heritage. Yet he managed to rule Egypt as a child of 10, and become the most famous pharaoh of today. Many believed he was murdered in 1323 B.C. by hangers-on, jealous that a boy was running the vast Egyptian empire. Other theories include malaria, sickle cell anemia, or unintentional poisoning. But after doing a CAT scan on his mummy, scientists now believe Tut died from a broken leg that became infected; an injury they theorize was caused when he "accidentally" fell off his chariot.
