Min Bahadur Sherchan died of a heart attack at base camp on Saturday afternoon, according to the Nepal Mountaineering Association (NMA).
"He was in good health. He used to walk 15 kilometers every day. But I think his age was quite a factor," Ang Tshering Sherpa, president of the NMA, told CNN. "He was too old to climb Mount Everest but he had a very strong will."
