Most people ride thebus to get from point A to point B, but riders taking a new route in Hong Kongare only interested in sleeping. Ulu' Travel Agency, a tour company in HongKong, has designed a five-hour bus journey especially for passengers to sleepas much as they want. Tickets for the first tour on Oct. 16 sold out right away,The Washington Post reported.

Many people find it easy. But why? According to a website, there are several possible reasons.

White noise

White noise is a kindof noise made by sounds with different frequencies(频率) together. Buses are often crowded every day with people going toand from work. Therefore, they are the perfect environment for white noise. Theymake continuing noises. White noise makes people feel relaxed and helps themsleep.

Rocking movement

Another popular viewon why it's easy to fall asleep on buses is because of the rocking movement."The movement of buses feels like a mother shaking a baby in her arms. It isvery comfortable," Frankie Chow, the founder of Ulu Travel Agency, told The Washington Post.

When you were a baby,you were rocked to sleep. That makes you connect the rocking movement withsleeping. Sitting on a bus gives people similar experiences. That's why youwant to sleep. It's the rocking movement that induces sleep.

Long periods of inactivity

Onbuses, you don't move around very much. You just sit down and enjoy the sceneryas the bus moves along the road. Basically, you re away from the things that keepyour mind and your physical body busy. This inactivity also slows your brain activitydown because there's no stimulus(刺激物) to keepit awake.

Increase in carbon dioxide

Buses often get crowdedwith people going to and from work. Carbon dioxide (二氧化碳) increases when there are lots of people in a small place. Thethinner oxygen (氧气) slows the brain down, causingpeople to feel sleepy.

    When something goes wrong, it can be very satisfying to say, "Well, it's so-and-so's fault. "or "I know I'm late, but it's not my fault; the car broke down. " It is probably not your fault, but once you form the habit of blaming somebody or something else for a bad situation, you are a loser. You have no power and could do nothing that helps change the situation. However, you can have great power over what happens to you if you stop focusing on whom to blame and start focusing on how to remedy the situation. This is the winner's key to success.

    Winners are great at overcoming problems. For example, if you were late because your car broke down, maybe you need to have your car examined more regularly. Or, you might start to carry along with you the useful phone numbers, so you could call for help when in need. For another example, if your colleague causes you problems on the job for lack of responsibility or ability, find ways of dealing with his irresponsibility or inability rather than simply blame the person. Ask to work with a different person, or don't rely on this person. You should accept that the person is not reliable and find creative ways to work successfully regardless of how your colleague fails to do his job well.

    This is what being a winner is all about - creatively using your skills and talents so that you are successful no matter what happens. Winners don't have fewer problems in their lives; they have just as many difficult situation to face as anybody else. They are just better at seeing those problems as challenges and opportunities to develop their own talents. So, stop focusing on "whose fault it is. " Once you are confident about your power over bad situations, problems are just stepping stones for success.

    I just returned to my hometown of Wilson Creek. I was away for 10 years. So many things have changed around here. When I left Wilson Creek, there was a small lake in the south-east of the town.

    They have filled in the lake and built a large shopping center and a swimming pool there. They have also built a new post office just across from my old school.

    The baseball stadium(体育场)in the north-east of Wilson Creek has also changed a lot. They have now added a new stand(看台). Now the stadium can seat a few thousand people. It looks really great.

    The biggest changes have taken place in the town center. It has become a pedestrianised area(步行区) and you can't drive there anymore. They have built a large square and a cinema. There is also a new street cafe and a grassy area.

My street looks just the same as it always has been, but a public library has appeared on the next street. There used to be a park there but they have cut down all the trees. What a pity! The library now has a large green area in front of it but it's not the same as when the park was there.

    Another change is the new restaurants that have opened in Wilson Creek. A Chinese restaurant and an Italian restaurant have opened in the town center, and a Mexican restaurant has opened near my home. I'm going to the Mexican one tomorrow!
