It seems more than a little patronizing for Westerners to lament the loss of the good old days when life in the Khumbu was so much simpler and more picturesque. Most of the people who live in this rugged country seem to have no desire to be severed from the modern world or the untidy flow of human progress. The last thing Sherpas want is to be preserved as specimens in an anthropological museum.
