Changpa of Ladakh.
To watch them in action is eye feast, to spend time with them feels good and to live with them for few days is the great way to learn philosophy of life. They are not much so called rich or civilised people, but being with them and learn to live life in very simple ways is great learning where no university or collage can teach you. I must say money or a extraordinary book knowledge never teaches how to you should live life happily and peaceful. I am really lucky to be stay with them for last few of years, which really helped me to enrich my experience.
