Sherpa is one of the major ethnic groups native to mountainous regions of Nepal, as well as certain areas of China, Bhutan, India, and the Himalayas.
Sherpas are highly skilled and experienced climbers. They are paid to prepare the route for foreign climbers to follow, fix ropes in place, and carry the necessary climbing kit up the mountain.
Climbing Everest is tough and being a Sherpa is really a risky job.
