In the Iban tribe they have lived in long houses. It is our understanding that multiple families live in the same long house which is divided into separate living quarters. As one group dies, the next group moves into it. Ibans were headhunters and practice this up until about 50 years ago. Some headhunters are still alive. They have a tattoo on their necks identifying them if they had killed someone. There are stories that when Japan invaded Malaysia, the headhunter warriors took their toll on the Japanese.
