London, Apr 8 (ANI): At 7ft 4 1/2ins, Brenden, from Ellensburg, Washington, is the tallest boy in the world, and will be featured in an ITV1 documentary 'Superhuman', along with other adolescents who stand higher in a crowd.
Most of the teenagers in the documentary tower over Peter Crouch, the 6ft 7ins England footballer, and have to have custom-made beds, clothes and houses to accommodate their frames.
Although Brenden was born a normal 7lb 4oz, at 12 months he was the size of a three-year-old.

Another teenager is 17-year-old Thai Malee Duangdee, who is the tallest girl in the world with a height of 6ft 10ins.
Also appearing in the programme will be Marvadene Anderson, 15, who stands at 6ft 9 1/2ins and has been named the second tallest girl in the world.Britain's tallest family, the Van Neses, will also appear in the documentary.
The family comprises of Dad Frank, 6ft 10ins, mum Miriam, 5ft 11ins, sons Vincent, 16, 6ft 10ins, Lucas, 15, 6ft 8ins and Franklin, 13, 6ft 1in. Daughter Naomi, 11, is 5ft 9ins. (ANI)
