The world's shortest man, He Pingping, in comparison to the world's tallest man, Sultan Kosen.
He is 2-feet, 5-inches tall.
Kosen, seen here in London, is more than 8 feet tall as a result of a rare hormonal condition called acromegaly, which causes the pituitary gland to produce too much growth hormone, usually as a result of a noncancerous tumor on the pituitary gland.
Acromegaly causes the skeleton and internal organs to grow disproportionately. When the organs that also respond to growth hormone, like the kidneys, intestines and the heart, become enlarged, they become weakened. Patients typically also have deep voices and enlarged tongues, making it difficult to swallow.
