There are actually marriages like that here in the Philippines, but of course, it happens only in the mountains. Parents give their beautiful young girls to some old coot and let them marry in exchange for money, work, a piece of land, etc. Most of the time, it's under 15. I think one of our former house helps was engaged to be married to a 60-year old, or was it her mother, who got married at 12 or 13 with a 60-year old and gave birth to her? Once their daughter is able to give birth, the parents usually give them/sell them to the DOMs. It's a dirty practice of the upland people.
