How many frontiers are left? A 40-year-old British man has just completed a 46,000-mile journey around the world completely under his own power by bicycling, rowing, hiking and rollerblading.
The man, Jason Lewis, was just 26 years old when he and a friend set out to circumnavigate the globe without relying on engines, motors or wind power such as sailing; no tramp steamers to carry them across oceans or trains to cross deserts.
Along the way he broke both legs when he was hit by a car while rollerbladding in the US, was attacked by alligators, snakes and pirates, and headed off alone when his friend dropped out of the scheme in Hawaii.
