Yoruba
In the Yoruba culture, prostration and kneeling as a style of greeting have been practised for a long time. Boys and men prostrate and girls and women kneel when greeting someone thought to be older or in a high position. The most expressive form for men is completely lying down with only the head raised up. For the women, one can either kneel on both knees or just use a single knee without necessarily touching the ground.
