He's being called the tallest teen in the world! Brandon Marshall, 16, of England, measures at 7 feet, 4 inches! "I was about 6'7" when I was 13," he says. "I started to grow a lot more by then." Doctors say he's still growing, and because of his height, Brandon has to eat 8,000 calories day. His mom says everything has to be custom-made for him but one of his biggest problems is buying shoes.
