Clay Jenkinson's interview with adventurer Alan Mallory about his family's ascent of Mount Everest. That's 29,032 feet, a third of it in the Death Zone, where your body actually starts to die from lack of oxygen and other factors. Mallory walks us through the process—getting to Nepal, the cost, the outfitters, the journey to base camp, where you stay to adjust to the altitude, and then the slow, steady, and exhausting climb through four camps before attempting the summit. On the basis of his book, The Family that Conquered Everest, Mallory has a vibrant career as a motivational speaker. At the end he shares his adventures are ahead.
