[00:10.46]The relationship is certainly personal and spiritual [00:13.61]But above all it's practical. [00:15.98]Rarely killed and eaten, each cow is a precious source of milk or blood [00:19.75]forming much of the Dinka's diet. [00:22.29]Cow dung is burnt for fuel [00:24.65]The smoke and the ash deters the hordes of biting insects. [00:28.06]When they can, the Dinka catch fish from the swamp.
