Rumbur Valley, Chitral, NWFP, Pakistan Photograph (7 of 7) reproduced from Georg Morgenstierne's unique film documentary. A Kalasha youth excited by the dance. He is wearing a necklace and his face is thoroughly washed (one of the rare occasions). The tribes of Nuristan were known to seldom wash their bodies (normally a few times a year, and only before important religious festivities). One speculation is that the natural layer of bodily secretions, mixed with dirt thus accumulated, provides protection against cold, sunlight or infections.
