Nick Weston, 28, who lost his job due to the current financial crisis, built and lived in a treehouse in the woods of southern England, foraging for food, for six months. He was curious to see if it was possible to live as a 21st century hunter-gatherer. The latter-day Robinson Crusoe also kept a diary of the joys and hardships of tree-top living, which have now been published as a new book. [huanqiu.com]
