One gets no sense of teenage angst, depression, or insecurity among the Pirahã youth. They do not seem to be searching for answers. They have them. And new questions rarely arise. Of course, this homeostasis can stifle creativity and individuality, two important Western values. If one considers cultural evolution to be a good thing, then this may not be something to emulate, since cultural evolution likely requires conflict, angst, and challenge. But if your life is unthreatened (so far as you know) and everyone in your society is satisfied, why would you desire change?
