No I did not mean the Mongolians, they are pretty hardy. An photographer friend of mine showed me her photos taken of Mongolian herdsmen, she stayed with them for a while. I found an article on her and her book on Buckaroos, "Gathering Remnants". Can't find any photos of Mongolians there but you will see photos of my ex co-workers.
