Last month I read in the news that a team of scientists in China’s Hubei province were preparing to mount a search for the Yeti, or Bigfoot, in the Shennongjia Forest Region. One article said that the scientists were looking for foreigners to join the hunt. They wanted men “between 25 and 40 years old. With good physical health, they should also have a basic knowledge of biology and know how to use a camera”.
