Article: If you were walking around a supermarket and saw a woman with a shaved head, a ring through her nose, a tattoo design on her arm and she has a small child in her shopping _ , 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 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.

Article: Studying abroad will shape you in various ways. You will learn things you never would have if you had stayed home. When you are young and unattached, you should travel. Besides, you just might save a large sum of money. College is expensive in the United States. It's cheap or free in other countries even for foreigners, so why not get out of here and come back smarter? More and more American students are currently studying at German colleges. That number has increased 20% over the last three years. Living costs are about $7,000 a year, which is even lower than in other European countries. Germany encourages international students. They create a multicultural landscape that benefits German students as well. According to a new report, Germany is home to six of the world's 100 best universities. These schools offer around 900 degrees completely in English and many German students speak the language. You could be part of Finland's excellent education system. The Finns charge no tuition and offer a number of courses purely in English. They would be happy for you to add flavor to their school scene. Cost of living there is high. Be prepared for frosty winters that far north, but you will get that sweet midnight sun in the summer. Many other European nations offer cheap or free college for foreign students, but if South America is more your thing, try Brazil. Most of the education will take place in Portuguese, so if that is in your plan you can study near beautiful beaches and jungles. The University of Sao Paulo and State University of Campinas are both highly ranked internationally. Your money will go a long way there, too. Many of the lessons you will learn will be outside the classroom. Living on the economy in a foreign country will keep you on your toes. You will learn new customs, how to bargain, stay safe, budget and become more flexible with people. There is no better way to learn a language than by immersing yourself in it. At first, it will be the toughest thing you have ever done. Eventually, it will become second nature.
