It is amazing to realize how different the conceptions of beauty are around the world. For example, in certain tribes in Africa it is custom for women, at a young age to cut a hole and insert a clay disc in their bottom lip. It is a life long process by gradually increasing the plate size. The goal is to stretch one's lip as much as possible. This has been a long lasting tradition. Dating as far as 8700 BC, even in multiple countries around the world such as: Kamchatka, Iran, the Balkans, Sudan, Mesoamerica, and Coastal Ecuador. Though, in each culture the placement and style of the plate varies. The Makonde people of southeast Tanzania wear the discs in their upper lips.
Beauty is a controversial word because it can mean have so many definitions, some we can't understand. To us, in our society, we might find lip plating strange or repulsive, but to the Africans it is their conception of beauty. For the bigger ones plate, the more beautiful they are considered.
