Norbu Tenzing, Sherpa and Everest's climbing 'industry'

It's a risky job being a mountain guide from Nepal's ethnic Sherpa community, for a tiny share of a multi-million dollar reward. 

Norbu Tenzing, son of Tenzing Norgay, works as vice-president of the American Himalayan Foundation which funds education and healthcare projects for Sherpas, Nepalis, and Tibetans throughout the region.

He talks to Kathryn Ryan about the "business of Everest," as is laid bare in the upcoming documentary Sherpa,which tells of the people who pay the greatest price.
