The San are a nomadic hunter-gatherer population that has been living in the vast Kalahari desert region for over 20,000 years; they are present in Botswana and Namibia in good number, but also in South Africa and Zambia in small part.
The San do a rite of passage for both women and men.
The San's language is characterized by "click" sounds that are made by snapping the tongue against the palate, the teeth or the lips; they count up to 20 different clicks.
