This walking" bear rug" is 26-year-old "Yu Zhenhuan" of China, and 96 percent of his body is covered with hair. Yu’s pubelike pelt sprouts from everywhere but his palms and soles, to the tune of 41 hairs per square centimeter. What’s worse, his mane actually made Yu sick. His locks snaked so far into his ear that they not only caused him earaches and nausea but also cut off a third of his hearing. Luckily, a recent operation cleared out the old growth, which could have spelled trouble for Yu’s current career as a rock singer.
