WATCH: Four Minutes to Explore the Globe

Man who visited every country sums up his journey

In 2012, Graham Hughes successfully became the first person to visit all United Nations member states without flying.

On less than $100 a week, it took Hughes four years to complete his journey. In a newly released video, you can follow in his footsteps in all of four minutes—covering roughly one country per second.

It's a bit dizzying, to be honest.
