Each year, more than 1,000 people attempt to reach Denali's summit. Nearly half of those fail and several die trying—sliding off of icy cliffs, crushing bones against rocks, falling into hidden crevasses, or simply getting lost and succumbing to the cold. It's no secret—cold can kill (http://www.pbs.org/wgbh/nova/denali/body.html" Body Breakdowns). But why? Even some of the most physically fit and well-equipped climbers still die on Denali, debilitated by a strange and confounding sickness.
