Ethiopian tribesmen compete to get as fat as possible by drinking only cow milk and blood for six months while confining themselves to their mud huts

For half a year members of the Bodi tribe will drink nothing but fresh milk and blood from cows in order to pile on the pounds. During this time they are not allowed to have sex, or even leave their hut. The contest forms part of the Ka'el ritual, held to mark the new year. Every family is allowed to present an unmarried man for the challenge.
