Pokot men take it in turns to drink clotted blood from inside the carcass of a bull which was speared by a young man during an initiation ceremony in Baringo County, Kenya, January 20, 2016. Far from the bustling city of Nairobi, in an isolated corner of Kenya's Rift Valley, young men from the Pokot community spear a bull in a ceremony called Sapana that takes them into adulthood. Following the ritual improves men's marriage prospects, provided they can amass a dowry of livestock for their bride. Initiates can also take part in local decision-making in a region where tradition remains strong and cattle play a central part in daily life. (Photo by Siegfried Modola/Reuters)
