 This time Bruce wants a taste of life with the Kombai, a Papuan tribe. They are so remote it proves an adventure in itself, even with a local guide, just to find and approach them in the vast, largely unspoiled forests of New Guinea. The men go naked except for a penis-cover, which is applied after a bewildering penis-inversion, and go on long hunting and gathering trips. They live in dizzying high, self-made tree houses, once a useful protection against headhunters from the south. In their tradition, cannibalism is practiced only as ultimate punishment for khakhua-kuma, evil human  soul-eaters . There is no metal, all tools are still made from wood and stone. Their staple food is sago, to Bruce s Western taste inedibly dry but easily available in the wood, leaving them lots of spare time. The favorite food are wild pigs and, for special celebrations, bred pigs; as delicious as those taste to the Westerner, so disgusting seems their smaller treat, fattened grubs, a smaller kind is put in the ear to eat the wax.
