Tallest man in the world

The tallest living man is Sultan Kosen from Mardin, Turkey. He is the world's tallest man according to the latest Guinness world record book, who measured 8 ft 3 inches (251.4 cm) in Ankara, Turkey, on 08th February 2011.

Sultan first became the world's tallest living man in 2009, when he measured 246.5 cm (8 ft 1 in) in height. The part time farmer was the first man over 8 ft (2.43 m) to be measured by Guinness World Records in over 20 years.

Sultan also holds the record for largest hands of a living person, each one measuring 28.5 cm (11.22 in) from the wrist to the tip of the middle finger. He previously held the record for largest feet on a living person, with his left foot measuring 36.5 cm (1 ft 2 in) and right foot measuring 35.5 cm (1 ft 1.98 in).

Speaking at the time of his entry into the Guinness World Records family he said: 'I never imagined I would be in the GWR book, I dreamed about it, but it was still a huge surprise'.

Sultan's growth and massive height caused by a condition known as "pituitary gigantism", which is the result of an over-production of growth hormone. The effects of over-production includes large hands, a thickening of the bones, and painful joints.Sultan didn't start his incredible growth spurt until he was 10 years old. But he finally appears to have stopped growing. Revolutionary gamma-knife surgery on the tumour affecting his pituitary gland, provided by the University of Virginia, USA, in August 2010, has finally halted his production of growth hormone.

Sultan is one of five members in a family, with three brothers and one sister, The rest of his family, are all 'normal' sized. Because of his extreme height he was never able to finish school but works occasionally as a farmer to support his family.
