year-old Nepali mountaineer, nicknamed “Super Sherpa”, has climbed Mount Everest for a record 21st time , breaking his own record for the most summits of the world's highest mountain, hiking officials said. Apa Sherpa, who lives in the United States, reached the 8,850-meter (29,035-foot) peak of the mountain along the Southeast Ridge route late last month, pioneered by New Zealand's Sir Edmund Hillary and Sherpa Tenzing Norgay, who were the first to reach the top of the world in 1953. “It takes a lot of will power to do something as difficult and needing a lot of strength at very high altitude over and over and over again,” climbing historian Elizabeth Hawley said.
