I love the Indians, and sometimes they go above and beyond the call of duty to defend stupid cultures.
In order to minimize the need to fight over small land that they inherit from their ancestors,(does it ring a bell... like some communities in Kenya), they practice fraternal polyandry. This is where two brothers share one wife and reduce the need to divide the piece of land over two brothers.
I know what you are all thinking. What about the bedroom pleasures? Believe it or not, they share in shifts, to reduce commotion. I have to take out my hat to the lady of the house, for she has to be the most satisfied in the village.
If that is not kinky enough, the tribe has another tradition. if the husband owes debts that he can't pay, he will lease /loan his wife for a number of days to the creditor which in most cases is the land owner.We are yet to know if the wife can enjoy such privileges are having two husbands, but i suspect the answer is no.Talk of barter trade!!
