Min Bahadur Sherchan, climbed Mt. Everest, the 29,028 feet (8,848-meter) peak, at the age of 76 in 2008. But, the 2009 edition of Guinness Book of World Records had Japanese national Yuichiro Miura as the oldest person to reach the top of the world at 75.
Sherchan did apply for his rightful entry in the record book but getting the honor was as tough as climbing the highest peak itself.
Sherchan first thought of setting a record on mountaineering in 1960. He wanted to be the first to climb Dhaulagiri (8,167m) but another team succeeded in climbing it before he could attempt. After 40 years, in 2002, he decided to be the oldest person to climb Mt. Everest breaking the records set by Japanese mountaineers. He started his trainings at the age of 72 and climbed the peak on May 25, 2008 at the age of 76 years and 350 days (almost 77 years).
