Since I've been in Ghana I've noticed that a lot of people have scars on their faces. Usually one to three small ones beneath the left eye. I finally asked someone about it today. Apparently, if children have convulsions the parents take them to the priest (witch doctor) and he cuts their face and rubs in this black powder, which is just the ash from a certain type of leaf they burned. They do the same thing if you have headaches, but it's a cut in the forehead and a different kind of leaf.
A lot of the other scars are tribal marks, mostly from people in the north I believe. Two of the new kids at the orphanage (the first orphanage I went to) have all sorts of tribal scarring on their bellies. One of them is like a sunburst around the bellybutton. I took pictures. After I took pictures of the 2 year old another boy lifted his shirt to show me his scars and wanted me to take pictures. Very strange.
