     If you were walking around a supermarket and saw a woman with a shaved head, a ring through her nose,

a tattoo (纹身) design on her arm and she has a small child in her shopping trolley, what would your opinion

be? Do you think this kind of body decoration is attractive or ugly? Different people have different ideas. The

following are some examples of body decoration from around the world.

     In many parts of Africa, it is thought that an attractive girl should have really shinny skin.

     On Bali, a little island in Indonesia, they believe that a beautiful woman or handsome man must have

perfectly straight, flat teeth. The Balinese believe that teeth with pointed edges make you look like an ugly wild

animal. So when a girl or boy becomes a teenager, he or she is taken to a special person in their village who

will file off teeth points to make them smooth and flat. There is no anesthetic (麻药) and this tooth filing is

really painful. It is a kind of test. If you can stand it without screaming or crying too much, then you are

thought ready to become an adult.

     In Myanmar, there is a small group of people who are called the "Papaung". They believe that a woman can

only be really beautiful if she has a long neck. I mean a VERY long neck. Now you might think that you are

either born with a long or short neck and that there's nothing whatever you can do about it. But you would be

wrong! At around the age of 5, a Papaung girl has heavy metal rings fitted around her neck, tightly between the

chin and shoulders. Each year more rings are added and very, very slowly their weight pushes the shoulders

down, in this way making the neck look longer. A Papaung woman will wear her neck rings all her life, never

once taking them off.
