Yeah, they just had a special on them on the travel channel, the "land divers" of Vanuatu (Pentecost). I got a kick out of it, they had alot of free time, because it was easy to live off the land. So the men would spend all their evening time getting high together on some kind of plant juice. The women all complained to the camera crew, that the men waste all their time getting high. :-) I guess our civilizations have one thing in common.
