High Altitude Resilience - Mountain Legend Reinhold Messner

Mountain climbing legend Reinhold Messner grew up climbing with his siblings in the Italian Alps around Bolzano. Unlike 7 of his 8 siblings, he kept climbing even higher mountains throughout his life, until, he summited all of the world's tallest peaks without supplemental oxygen. At the time, scientists proclaimed it impossible to climb above 8,500 meters without breathing through an oxygen tank. Messner describes his personal journey to keep climbing the tallest mountains despite losing his brother, as well as fingers and toes to high altitude climbing.
