Women's scars and rituals involved beauty (piercing ears and noses, binding feet, and wearing corsets); men's involved protecting women. In cultures in which physical strength is still the best way to protect women, as among the Dodos in Uganda, each time a man kills a man, he is awarded a ritual scar; the more scars, the more he is considered eligible.
