Kottke on the indigenous Baining people of Papua New Guinea, who when awake scarcely do anything but work, out of the belief that unstructured fun is a waste of time. One wonders if we are drifting in their direction:
The Baining eschew everything that they see as “natural” and value activities and products that come from “work,” which they view as the opposite of play. Work, to them, is effort expended to overcome or resist the natural. To behave naturally is to them tantamount to behaving as an animal. The Baining say, “We are human because we work.” The tasks that make them human, in their view, are those of turning natural products (plants, animals, and babies) into human products (crops, livestock, and civilized human beings).
They do not allow infants to crawl and explore on their own. When one tries to do so an adult picks it up and restrains it.
