How amazing is your brain? What if someone took away your eyes? Could you possibly see with your brain?
Ha, ha, ha…judge for yourself. This video below is not a trick. He’s actually seeing with his brain—the eyes you and I have are just tools. It’s the brain that does all the grunt work.

On May 25, 2001, Erik Weihenmayer became the only blind man in history to reach the summit of the world’s highest peak – Mount Everest. On August 20, 2008, when he stood on top of Carstenz Pyramid, the tallest peak in Austral-Asia, Weihenmayer completed his quest to climb the Seven Summits – the highest mountains on each of the seven continents. Erik is joined by fewer than 100 mountaineers who have accomplished this feat. Additionally, he has scaled El Capitan, a 3300-foot overhanging granite monolith in Yosemite; Lhosar, a 3000-foot ice waterfall in the himalayas; and a difficult and rarely climbed rock face on 17,000-foot Mt. Kenya

In September, 2003, Erik joined 320 stellar athletes from 17 countries to compete in the Primal Quest, the richest and toughest multi-sport adventure race in the world: 457 miles through the Sierra Nevada’s, nine days, sixty thousand feet of elevation gain, and no time-outs. Averaging only two hours of sleep a night, Erik and his team surged past the finish line on Lake Tahoe, becoming one of the 42 teams to cross the finish line out of the 80 teams that began.
