Brunei - Temburong River - Raleigh International expedition men on log

Grinning from ear to ear, young volunteers throw themselves over a fallen tree during a strenuous activity on a Raleigh International expedition in the rainforests of Brunei, Borneo, one of the remotest and most dangerous habitats on the planet. It has been a life-changing experience for them and their new-found friends from all over the world who will have had to raise several thousands of sponsored Pounds for the privilege of spending two months away from a dull, comfortable life at home, rather than building community projects like bridges or schools. Raleigh International is a charity that provides adventurous and challenging expeditions for people from all backgrounds, nationalities and ages, especially young people. Over the last 23 years, 30,000 people have been involved in more than 250 expeditions to over 40 countries. | Location: Temburong River, Tembu (Photo by In Pictures Ltd./Corbis via Getty Images)
