The Ovahima people is found in Northern Namibia. An interesting fact is that they never bath or wash themselves with water at all. They have a very interesting cleaning ritual, which takesa couple of hours. They start cleaning themselves very early in the morning by burning wild herbs and sit in the smoke. They also clean their leather clothes with the smoke.
When a young girl or a woman have such a thing around the neck as this young girl, it means that they aren't married.
