Bao Xishun (born 1951) is a herdsman from Inner Mongolia, China. Bao was formerly recognized by Guinness World Records as the world's tallest living man. Measured at 2.361 metres (7 ft 8.95 in) tall at the Chifeng City Hospital, Bao Xishun has no growth disorder like gigantism. Bao suffers from rheumatism, although this has been attributed to his childhood habit of sleeping outdoors, rather than a height-linked disorder.
He Pingping (b. 1988) is a Chinese man who is under consideration to be recognized as the world's shortest man. He is currently applying to the Guinness World Records.[1]
The 19-year old measures 73 cm (2 ft 4 in) high, and is the third child to a family in northern China's Region. He has 2 sisters, both of which developed at normal rates and are now married. At birth he was as small as a palm. When it became apparent the child was growing very slowly, doctors diagnosed it as the bone deformity Osteogenesis Imperfecta.
