The tallest man living is Sultan Kösen (Turkey, b.10 December 1982) who measured 251 cm (8 ft 3 in) in Ankara, Turkey, on 08 February 2011.
The part-tme farmer was the first man over 8 ft (2.43 m) to be measured by Guinness World Record in over 20 years.
Indeed, GWR only knows of 10 confirmed or reliable cases in history of humans reaching 8 ft or more.
Sultan also holds the records for widest hand span and largest feet on a living person.
Speaking at the time of his entry into the Guinness World Records family he said: 'I never imagined I would be in the book, I dreamed about it, but it was still a huge surprise'.
Sultan is one of five siblings, with three brothers and one sister,. The rest of his family, including his mum and dad, 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.
He describes one of the advantages of being tall as being able to help out his mum out with jobs such as changing a broken light bulb and hanging curtains.
Disadvantages to his height he lists include not being able to find clothes or shoes that fit or finding it extremely hard to fit into a regular size car.
Like every young man in their twenties, Sultan enjoys listening to music, playing computer games and watching movies.
