As mobile phones d__7__, they are getting smaller with buttons c__8__ together. Texting with a smaller phone is worse than using a larger phone with b__9__ buttons. Using computers and playing video games can cause the same problem. So more and more people could find t__10_ with RSI.

Many people say that they are working too many hours. They don’t have enough time to relax or to stay with their family.
Work hours are different from one country to another. In France, people spend about 1,646 hours a year at work. In Japan, however, people work about 2,159 hours a year. That means a Japanese worker works 513 more hours a year than a French worker.
Why do people work so many hours? Some people work extra hours because they want to make more money. However, many companies don’t pay overtime. Their workers don’t get more pay for more work. Some people think it’s their duty to work more hours. Some are afraid of losing their jobs if they don’t work more hours.
Many people say that their vacations are too short. In France, people get five weeks of paid vacation a year. In Germany, they get four to six weeks, and in the United States, two weeks. One study shows fewer than half of workers used all their vacation days. In Great Britain, there is a saying, “All work and no play makes Jack a dull boy.” If that is true, there must be a lot of dull people in the world.

Shenzhen's fast development has made it become China's most crowded city! There are about 15 million people living on its 1991square kilometers. On each square kilometer averagely live 7500 people. It is 1080 more than that in Hong Kong, and nearly 800 more than that in Guangzhou.
