Another inspiring video from TED! After Lewis Pugh swam the North Pole, he vowed never to take another cold-water dip. Then he heard of Lake Imja in the Himalayas, created by recent glacial melting, and Lake Pumori, a body of water at an altitude of 5300 m on Everest. And so began a journey that would teach him a radical new way to approach swimming, new challenges and think about climate change.

What’s your biggest challenge today? And do you need a radical new way to handle it?
