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.

So now I’m sure you will all agree that different people have different ideas about what is beautiful.

For thousands of years humans have used herbs, roots, and other things from nature to cure disease. Scientists looking for new cures often visit traditional healers. They find out what plants are used in healing. Then they look at what the plant contains. They find the active ingredient(成分), which is the chemical in the plant that works to heal. Many of the drugs we use, including aspirin, have come from these natural medicines.

In recent years, many people in the US have taking what are legally known as dietary supplements(补药). They may be vitamins or minerals. They may be herbs that help with health problems, such as depression. Some of them are teas. Others are capsules or tablets. They are sold in natural food stores, drug stores, and groceries. Most people think that because these products are natural they are also safe. This is not always true. There are many plants that are poisonous. There are others that have bad side effects.

The New England Journal of Medicine publishes medical research. A recent edition called for the government to regulate dietary supplements. Several doctors wrote to the Journal and told of bad experiences people have had with dietary supplements.

Dietary supplements aren't tested in the same way as drugs. There is not always proof that the supplement really does what it is supposed to do. There is also a problem with purity of the supplements. Supplements have been found to contain things that are bad for the body. For example, the California Department of Health found that of 260 herbs grown in China, one third contained heavy metals. These are minerals such as lead and mercury(水银). They are very poisonous, even in tiny amounts.
