Robert became 9'0 and the tallest man in history and died at 22 from a random wound infection.
Robert suffered from an extremly rare and undisclosed Form of hypertrophy. At just the age of 1 he was close to 4 feet, at age 8 he overcame his father 5'11 at 6'0 and turned 8'4 at his 18th birthday.
Roberts condition would have enabled him to grow all through his life to the point he likely would have died from "overgrowth" around the time he would have turned 11'0 which would be in his 30s.
