Input: Consider Input: Article: People like to look in the mirror often when they have a young and beautiful face. However, when one grows old, nobody wants to see their wrinkled old face in the mirror any more. So, many old people seldom look at their faces in the mirror. This is completely wrong. According to Wu Zhenyun, a professor from the Psychological Research Institute under the Chinese Academy of Sciences, a person's willingness to look in the mirror can reflect his or her mentality. When people don't care too much about their age, they will try to carry themselves with ease and natural poise . They don't mind looking in the mirror to see their own faces. Some people even love to look in the mirror from time to time to see whether they keep a good appearance. In this way, mirror becomes their best friend that help them to look confident. On the other hand, some people are afraid of being old. They don't want to see the wrinkles on their face and their hair turning grey. So they don't want to look in the mirror. This actually reflects a negative attitude they hold towards life. In the long term, they might suffer from psychological pressure or some sort of depression, which is actually not a wise act. " Everyone can make themselves look charming at every age stage. If one is confident, one will always look beautiful, it shows that they accept themselves." professor Wu said. Mirror cannot only give confidence to one. By looking in the mirror, one can even find the traces of some diseases from one's own face.

Input: Consider Input: Article: Shopping in the United States changes a lot.About ninety years ago most people shopped in small stores that were owned by one person or a family.Women went from the bakery to the butcher's to the grocer and on to the fruit and vegetable seller in order to get their food for the week. Then about sixty years ago, supermarkets were born.In a supermarket, people could get all the different kinds of food they needed without going to different stores. The next big change in shopping in the United States was the shopping mall.A shopping mall is a group of stores under one roof.Because malls allowed people to shop without worrying about the weather, they soon became very popular.The mall became a place for people to socialize in addition to shopping.If you walk through a mall, you will see older people sitting, chatting and drinking coffee.Malls are places for teenagers to hang out.Many teens will often just "go to the mall" and spend time with their friends. The recent change in American shopping was the superstore.Large chain stores such as Wal-Mart, Office Depot and Toys "R" Us have been built all across the United States.Because they are so large, they can buy goods at a great discount and sell them much cheaper than smaller stores. Sometimes, when they are built near small towns, many of the small town stores have to close.They just cannot compete with their giant neighbors. And now, online shopping is becoming more and more popular all over the States.People are too busy to go to the physical stores, so they go shopping over the Internet.Online shopping has lots of advantages.For instance, online stores are usually available 24 hours a day.Searching or browsing online shops can be faster than browsing the physical stores.While, online shopping also has its disadvantages.People are at higher risk of being cheated on the part of the merchant than in a physical store.And privacy of personal information may be let out.
