The Tidong are a group of people from northern Borneo with a particularly uncomfortable wedding custom. For the 3 days and 3 nights following the wedding, both the bride and groom are prohibited from using the bathroom. That means no urinating, no defecating, and no bathing. They believe that custom will lead to a long, happy, and fertile marriage. In order to achieve this, the newlyweds are allowed to eat and drink only very small amounts and are watched very closely by family members.
