Testing the Limits of Human Endurance in Antarctica - Ben Saunders

Well into the 21st Century, humans have mapped most of the Earth's land masses and there very few blank spaces of the map to be filled. So why did polar adventurer Ben Saunders try to finish the 1,795 mile human-powered journey that Robert Falcon Scott died starting? He tells Boyd that he frequently asked himself that question during his 105 days on the exposed ice, but he says he hoped to explore the physical and mental boundaries of humans, rather than any space on the map.
