A Samoan airline says that it is the world's first carrier to charge passengers by their weight. Samoa Air, which opened in 2012, asks passengers to give their personal weight during booking, which is then charged according to the length of a flight. The customers will also be weighed just before they board the plane.

    "It is believed that all people throughout the world are the same size," Samoa Air CEO Chris Langton said. "Airplanes always run on weight, not seats."

    "There is no doubt in my mind that this is the concept of the future. This is the fairest way of your travelling with your family or yourself."

    Though the airline introduced the plan last November, it caught people's attention last week when the carrier began international flights to neighboring American Samoa.

    Almost at the same time, a Norwegian economist, Bharat Bhatta, published a report suggesting that airlines should charge obese passengers more.

    The Pacific Islands contain some of the world's most common countries for obesity, many ranking in the top 10, according to the World Health Organization (WHO). Samoa is ranked number four, with 59.6 percent of the population considered obese, said the most recent WHO report.

    According to Samoa Air's latest schedule, the airline charges up to $0.57 per kg for flights in Samoa and $1.03 per kg for its only international flight to American Samoa, around 250 miles.

    Children under 12 are charged 75 percent of the adult rate, with fares also based on weight. Any overweight baggage is calculated at the same rate as the passenger's personal weight.

    The plan could actually prove cheaper in some cases, such as for families travelling with small children, and Langton said customer reaction has mainly been "amazingly positive".

    The idea of charging passengers by weight has been hotly discussed before, and in the US some airlines require those who do not fit into a seat comfortably to buy a second seat.

    While both Europe and the United States of America are considered the Western world, it's good to know there are some differences in culture. If you are considering moving to a European country, you will find the information below helpful as you plan your move.

    One cultural difference is how the countries perceive（感知）time and space. For example, a house in the United States that is 200 years old would be considered ancient. This is probably because America is a fairly young country. However, in Europe, something would not be considered ancient unless it was at least 2,000 years old. However, perception of distance seems to be the opposite. While Europeans would consider 100 kilometers a long way to drive, Americans would think twice. This could be due to the fact that Europe is smaller and more heavily populated. In fact, the United States is over twice the size of Europe.

    Cars are another factor that differs greatly between Europe and the United States. American automobiles usually have automatic transmissions（传动）while European cars generally have manual gears（手动变速器）. European automobiles are smaller and more round-shaped, while American cars are larger and more square-shaped. Trucks and limousine are vehicles that American enjoy. In Europe, however, these types of vehicles are hardly seen, as they prefer smaller cars due to parking and traffic congestion.

    The view of education is another cultural difference between the European countries and the United States. In America, parents may save for many years and even go into debt to pay for their children to attend college. Most schools and universities in Europe, however, are free of tuition. In fact, it is just expected for children to attend college there and not a privilege（特权）, as in the United States.

    So many of us hold on to little complaints that may have come from an argument, a misunderstanding, the way we were raised, or some other painful events. Stubbornly, we wait for someone else to reach out to us—believing this is the only way we can forgive or rekindle a friendship or family relationship.

    A friend of mine, recently told me that she hadn't spoken to her son in almost three years. She said that she and her son had had a disagreement about his wife and that she wouldn't speak to him again unless he called first. When I suggested that she be the one to reach out, she said, “I can't do that. He's the one who should apologize.” After a little gentle encouragement, however, she did decide to be the first one to reach out. To her amazement, her son was grateful for her willingness to call and offered an apology of his own. As is usually the case when someone takes the chance and reaches out, everyone wins.

    Whenever we hold on to our anger, we turn “small stuff(问题)” into really “big stuff” in our minds. We start to believe that our positions are more important than our happiness. They are not. If you want to be a more peaceful person you must understand that being right is almost never more important than allowing yourself to be happy. The way to be happy is to let go, and reach out. Let other people be right. This doesn't mean that you're wrong. Everything will be fine. You'll experience the peace of letting go, as well as the joy of letting others be right.

    You'll also notice that, as you reach out and let others be “right” they will become less defensive and more loving toward you. They might even reach back. But, if for some reason they don't, that's okay too. You'll have the inner satisfaction of knowing that you have done your part to create a more loving world, and certainly you'll be more peaceful yourself.

    Do you know of anyone who uses the truth to deceive(欺骗)?When someone tells you something that is true, but leaves out important information that should be included, he can give you a false picture.

    For example, someone might say,“I just won a hundred dollars on the lottery(彩票).It was great. I took that dollar ticket back to the store and turned it in for one hundred dollars!”

    This guy's a winner, right? Maybe, maybe not. We then discover that he bought $200 worth of tickets, and only one was a winner. He's really a big loser!

    He didn't say anything that was false, but he left out important information on purpose. That's called a half-truth. Half-truths are not technically lies, but they are just as dishonest.

    Some politicians often use this trick. Let's say that during Governor Smith's last term, her state lost one million jobs and gained three million jobs. Then she seeks another term. One of her opponents(对手) says,“During Governor Smith's term, the state lost one million jobs!”That's true. However, an honest statement would have been,“During Governor Smith's term ,the state had a net gain of two million jobs.”

    Advertisers will sometimes use half-truths. It's against the law to make false statements so they try to mislead you with the truth. An advertisement might say,“Nine out of ten doctors advised their patients to take Yucky Pills to cure toothache.”It fails to mention that they only asked ten doctors and nine of them work for the Yucky Company.

    This kind of deception happens too often. It's a sad fact of life: Lies are lies, and sometimes the truth can lie as well.

Keeping secrets is a burden

    “Don't tell anyone”. We hear these words when someone tells a secret to us. But it can be hard to keep a secret. We're often tempted to “spill the beans(说漏嘴)”, even if we regret it later.

    According to Asim Shah, professor in the Menninger Department of Psychiatry and Behavioral Sciences at Baylor College of Medicine, US, keeping a secret may well “become a burden”. This is because people often have an “obsessive and anxious urge to share it with someone”.

    An earlier study, led by Anita E. Kelly, a scientist at the University of Notre Dame, US, suggested that keeping a secret could cause stress. People entrusted(受委托的) with secrets can suffer from depression, anxiety, and body aches, reported the Daily Mail.

    But with secrets so often getting out, why do people share them at all? Shah explained that people often feel that it will help them keep a person as a friend. Another reason people share secrets is guilt over keeping it from someone close to them. A sense of distrust can develop when people who are close do not share it with each other. “Keeping or sharing secrets often puts people in a position of either gaining or losing the trust of someone,” according to Shah.

    He added that talkative people could let secrets slip out (泄露).But this doesn't mean that it is a good idea only to share secrets with quiet people. A quiet person may be someone who keeps everything inside. To tell such a person a secret may cause them stress, and make them talk about the secret. Shah said that to judge whether to tell someone a secret.

    Shah said that to judge whether to tell someone a secret, you'd better put yourself in their position. Think about how you would feel to be told that you mustn't give the information away. Shah also recommended that if you accidentally give up someone's secret you should come clean about it. Let the person know that their secret isn't so secret anymore.

    There are plenty of mindless activities to keep a child busy in this information age. Yet despite the competition, my 8-year-old daughter Alice wants to spend her leisure time writing short stories. She wants to enter one of her stories into a writing contest, a competition which she won last year.

    As a writer, I know about winning contests—and about losing them. I know what it is like to work hard on a story only to receive a rejection letter from the publisher. I also know the pressure of trying to live up to a reputation created by previous victories. What if she doesn't win the contest again? That's the strange thing about being a parent. So many of our own past scars and destroyed hopes can resurface in our children.

    A revelation (启示) came last week when I asked her, "Don't you want to win again?" "No," she replied. "I just want to tell the story of an angel going to first grade."

    I had just spent weeks correcting her stories as she spontaneously (自发地) told them. Telling myself that I was an experienced writer guiding the young writer across the hall, I offered suggestions for characters, conflicts and endings for her tales. The story about a fearful angel starting first grade was quickly "guided" by me into the tale of a little girl with a wild imagination taking her first music lesson. I had turned her contest into my contest without even realizing it.

    Staying back and giving kids space to grow is not as easy as it looks. Because I know very little about farm animals who use tools or angels who go to first grade, I had to accept the fact that I was co-opting (借鉴) my daughter's experience.

    While stepping back was difficult for me, it was certainly a good first step that I will quickly follow with more steps, putting myself far enough away to give her room but close enough to help if asked. All the while I will be reminding myself that children need room to experiment, grow and find their own voices.
