An interesting article on Jason Lewis who became the first person to circumnavigate the Earth without using motors or sails. He walked, cycled, & inline skated 5 continents, & kayaked, swam, rowed, & pedalled a boat across the rivers, seas, and oceans. It took him 13 years to complete, the 46,505-mile journey. This is an interview with him on what those 13 years were like, why he did it and what's next for him.
