Near the Yaida valley, we camped in the homeland of one of the last hunter gatherer tribes, the Wahadzabe, or Hadza. See National Geo article. They don’t farm, nor raise animals. They live on tubers, honey, berries, and hunting. They work about 4 hours a day, and play with their kids a lot. They own few objects, making thier dwellings from sticks and grass, fire from twirling a stick. They own an axe, and a few nails to pound to arrowheads. They seem happy. The women are equal, and not dependent upon the men, since they gather more calories from tubers than the hunters bring in.
