Aug. 13, 2004: Yu Zhenhuan waits for an interview beside his hospital bed in Shanghai. Yu - one of the hairiest men in the world - had ear surgery to remove hair that caused him to lose part of his hearing.
Yu, who is China's hairiest man, has 96 percent of his body covered with hair.
He may be hairy but he's not the hairiest. The Guinness record holders of that title are a pair of Mexican brothers who have a record of 98 percent hair cover on their bodies.
The hirsute Yu, who uses the name "woolboy" for his e-mail, has hair all over his body, except for the palms of his hands and the soles of his feet.
Eleven-year-old Pruthviraj Patil, of Maharashtra, India, was born with the rare symptom of hypertrichosis or "Werewolf" syndrome.
Since the age of 10, Pruthviraj has undergone several different treatments, and most recently laser treatment, but nothing has worked.
But Columbia University researchers believe they may have found a cure for this syndrome and are using injections of testosterone to stem Pruthviraj's excessive hair growth.
This undated handout photograph, provided by the Guinness Book of World Records, shows the record holder for the longest ear hair, Radhakant Baijpai. The Indian grocer, 58, has let his hair grow so long, it measures 9.8 inches in each ear.
Feb. 5, 2002: Before Radhakant Baijpai took the record for longest ear hair, B.D. Tyagi, a resident of Bhopal, India, held the record for longest ear hair. Bhopal's ear hair measured 4 inches. Baijpai took over the record in 2003.
