Bao Xishun is a herdsman from Inner Mongolia, China, who was recognized by Guinness World Records as one of the world's tallest living men. Bao suffers from rheumatism, although this has been attributed to his childhood habit of sleeping outdoors, rather than a height-linked disorder. Bao Xishun claims to have been of normal height until he was sixteen years old when he experienced a growth spurt for unknown reasons and reached his present height seven years later.
In December 2006, Bao Xishun was asked by veterinarians to assist them in removing shards of plastic from the stomachs of two dolphins. The dolphins had accidentally swallowed the shards, which had settled in their stomachs and caused a loss of appetite and depression. Veterinarians had failed to remove them, so Bao Xishun used his 1.06-metre long arms to reach into the dolphins' stomachs, to remove the plastic manually. (A similar operation was performed by American basketball player Clifford Ray, who was asked to use his long arms to save a California dolphin in 1978.)
