How do sherpas brave extreme heights?
Sherpas possess extraordinary physiological adaptations, including high lung capacity and efficient blood circulation, developed across generations living in thin mountain air. On dangerous peaks like Broad Peak where Nirmal Purja lost his life, their stamina and deep knowledge of treacherous terrain are crucial for guiding international climbers safely through extreme weather and shifting ice.
