Marriages

The women would be promised as the future wife of a young cross cousin. They would live with relatives of the husband. Due to the fact that many women die from the Kuru disease, most men don't end up with a happily ever after. Men will decide to remarry but they do spend alot of time unmarried. Most marriages end because of a death, the divorce rate is very low.
