Mount Everest by the Numbers

atkins-bookshelf-trivia“There [are] many, many fine reasons [not to climb Mount Everest], but attempting to climb Everest is an intrinsically irrational act — a triumph of desire over sensibility,” writes Jon Krakauer in his introduction to Into Thin Air: A Personal Account of the Mount Everest Disaster [of May 1996], “Any person who would seriously consider it is by definition beyond the sway of reasoned argument.” Well stated. So, if you are contemplating an expedition to summit Mount Everest, perhaps these numbers might persuade you to choose sensibility over triumph:

Top causes of death for climbers:
32% Fall
16% Exposure or frostbite
12% Altitude sickness

Top causes of death for Sherpas
35% Avalanche
