Next time you can't quite get yourself off the couch, remember this guy: Erik Weihenmayer lost his sight at age 13. Then he started climbing.
In a video drumming up support for the Access Fund, Weihenmayer takes on the Naked Edge. The Eldorado Canyon climb is rated a 5.11b. Translated into the lingo of non climbers, that means it's a serious climb and a "sobering challenge."
Pretty inspiring, considering Weihenmayer latches onto the smallest of handholds by feel. If that wasn't enough, he's also the only blind man in history to have climbed the tallest peak on all seven continents (the "seven summits"), including Mount Everest.
