David, an extremely tall and very regal Dinka who lives in Mapuordit, South Sudan, can tell you a lot about the danger of guarding cattle and goats. As a young teen he was keeping watch over his family's cows when he was attacked from behind in the darkness by a wild animal that gouged out both his eyes. He does not know the English word for the attacker: perhaps a jackal, perhaps a hyena, or a rabid wild dog. For sure, something vicious.
David has not let his total blindness--in a country where there are no services for the blind--prevent him from living a full life. He is the de facto leader of a simple compound for disabled persons. He is strong and upright and deeply gentle; his smile creases his whole face. He walks with great dignity, even when being led by a small child.
