The Kayan or Padaung are a group of the Karen people found in Myanmar and Thailand. They are known for a particular body modification, which consists of coiling lengths of brass around the neck of the women. The coils are first applied when the girls are about five years old, and the coil is replaced with longer coils as the weight of the brass pushes down the collar bone and compresses the rib cage, resulting in the appearance of a very long neck. The practice has seen a surge in recent years because the custom draws tourists who buy their handicrafts.
