The San Bushman were/are hunter-gatherers.
Their diet traditionally consists of 70-80% plants gathered primarily by the women which includes berries, nuts, roots, and melons. The remaining 20-30% is meat which the men hunt for with poisoned arrows. The San make use of over 100 edible species of plant and their knowledge of plants and customs is passed down thru the generations, not studied. The women are viewed as high importance and their opinions often take precedence especially if it concerns food.
I believe it will be a great honor to learn from the women of Tsumkwe.
