If anyone's up for becoming the first person to walk the 4,175-mile Nile River, it’s Levison Wood. In 2004, at the age of 22, he hitchhiked from England to India. Along the way, he walked across Afghanistan, where he later fought as a British Parachute Regiment captain on the front lines against the Taliban. In 2010, he delivered ambulances from London to Malawi, driving through 27 frequently hostile countries. Among many other adventures, he’s also led the first-ever crossing of Madagascar, pioneered whitewater rafting trips in South Sudan, and led an expedition to Siberia's Oymyakon, the coldest inhabited place on earth.
