In ancient Egypt, a shopkeeper discovered that he could attract customers to his shop simply by making changes to its environment . Modern businesses have been following his lead, with more tactics（策略）.

One tactic involves where to display the goods. For example, stores place fruits and vegetables in the first section. They know that customers who buy the healthy food first will feel happy so that they will buy more junk food later in their trip. In department stores, section is generally next to the women's cosmetics(化妆品) section：while the shop assistant is going back to find the right size shoe, bored customers are likely to wander over cosmetics they might want to try later.

Besides, businesses seek to appeal to customers' senses. Stores notice that the smell of baked goods encourages shopping, they make their own bread each morning and then fan the bread smell into the store throughout the day. Music sells goods, too. Researchers in Britain found that when French music was played, sales of French wine went up.

       When it comes to the selling of houses, businesses also use highly rewarding tactics. They find that customers make decision in the first few second upon walking in the door, and turn it into a business opportunity. A California builder designed the structure of its houses smartly. When entering the house, the customer would see the Pacific Ocean through the windows, and then the poll through an open stairway leading to the lower level. The instant view of water on both levels helped sell these $10 million houses.

    If it really is what's on the inside that counts, then a lot of thin people might be in trouble.

    Some doctors now think that the internal(内部的) fat surrounding important organs like the heart or liver could be as dangerous as the external fat which can be noticed more easily.

    “Being thin doesn't surely mean you are not fat,” said Dr Jimmy Bell at Imperial College. Since 1994, Bell and his team have scanned nearly 800 people with MRI machines to create “fat maps” showing where people store fat.

    According to the result, people who keep their weight through diet rather than exercise are likely to have major deposits of internal fat, even if they are slim.

    Even people with normal Body Mass Index scores can have surprising levels of fat deposits inside. Of the women, as many as 45 percent of those with normal BMI scores (20 to 25) actually had too high levels of internal fat. Among men, the percentage was nearly 60 percent.

    According to Bell, people who are fat on the inside are actually on the edge of being fat. They eat too many fatty and sugary foods, but they are not eating enough to be fat. Scientists believe we naturally store fat around the belly first, but at some point, the body may start storing it elsewhere.

    Doctors are unsure about the exact dangers of internal fat, but some think it has something to do with heart disease and diabetes(糖尿病). They want to prove that internal fat damages the body's communication systems.

    The good news is that internal fat can be easily burned off through exercise or even by improving your diet. “If you want to be healthy, there is no shortcut. Exercise has to be an important part of your lifestyle.” Bell said.

    In the story of “The crow and the Pitcher” from Aesop's Fables, a thirsty crow(乌鸦) drops stones into a narrow jar to raise the low level of water inside so he can take a drink.

    Now scientists have evidence to back up that story. New Caledonian crows actually do understand how to make water displacement work to their advantage, experiments showed. The results suggest that the birds are, at least in some aspects, as smart as first-graders, according to the study.

    Researchers, led by Sarah Jelbert at the university of Auckland in New Zealand, presented six crows with tubes filled with water. Inside the tubes, a worm or piece of meat on a piece of wood was floating, just out of reach of the crow. In front of the tubes, the researchers arranged a bunch of heavy rubber erasers that would sink, and light plastic objects that would float. The crows found out that they could drop the heavy objects into the tubes in order to raise the water level and get their snack.

    However, the birds handled awkwardly in experiments in which they could choose to drop objects in either a wide tube or a narrow tube to get a snack, the researchers said. Dropping objects into narrow tube would lift the water level by a greater amount and put the treat within reach after just two drops. In contrast, it took around seven drops to raise the snack to the same level in the wide tube. The crows obviously didn't realize this, and most of them went for the wide tube first.

    Previous studies showed that chimps and human children can solve similar tasks. In a 2011 study, chimps and kids found out that they could put water into a tube to reach a peanut that was floating in small amount of water at the bottom.

    A handsome man can earn a fifth more than a plainer colleague (同事) but a beautiful woman is not paid a penny more than her average-looking colleague, new research has shown.

    The study by senior economists (经济学家) found that being good-looking meant male workers could earn 22 percent more than average-looking colleagues. Researchers said good looks did not give women a similar advantage.

    Andrew Leigh, the former economics professor at the Australian National University who co-authored the report, said: "Beauty can be a double-edged sword for women."

    "Some people still believe good looks and intelligence (智慧) are incompatible (矛盾的) in women so a good-looking woman can't be that productive, but it doesn't affect men's pay."

He said that although he believed good-looking women may also earn more, the research did not support his theory.

    The research found that handsome men in all jobs, from manual labour to highly-paid professional careers, can earn 22 percent more than their colleagues doing the same work.

    Men with below-average looks face a battle in the office, with ugliness reducing a man's earnings by 26 percent compared to an average-looking worker.

    Former male model Ian Mitchell, 28, who has a first class degree in history from Edinburgh University and now works for a cosmetics (化妆品) company, told the Sunday Times: "It gives you confidence, and I suspect people tend to warm to you more quickly."

    The study, named Unpacking the Beauty Premium, was the largest exercise of its kind and repeated a survey from 1984 to see if the beauty premium had changed.

    Leigh said the research showed people in the workplace were "lookist (以貌取人的) " and he hoped the findings would encourage employers to remove their prejudice(偏见).

    Where can you find a nice place to relax on holiday for both you and your children? Well, I suggest you try the beautiful and green Isle of Wight (IOW). The Isle of Wight is one of the main tourist attractions. Here is some information on a few of the attractions on the IOW.

    Dinosaur Isle

    It is located in Sandown, a seaside town on the southeast coast. It's a large, lovely museum, both fun and educational. Here you can see a large fossil collection of all kinds of dinosaurs, as well as a gift shop. You can walk into the past and then the future, learning about the history and the development of the civilization of dinosaurs that lived 120 million years ago.

    Robin Hill Country Park

    The park is in the beautiful countryside, and is suitable for children's parties and games. It has five new gardens, and offers great opportunities to see and take pictures of the rare red squirrels.

    The West of the Wight

    Here we have the Marine Aquarium, the Archaeology Exhibition and the Model Railway. They offer another opportunity to combine fun with learning. This is a great place to see ancient boats crossing the narrow strait between the island and the mainland.

    The Wight Bus Museum

    This museum is run completely by unpaid volunteers. It has a bus collection stored in what was once a warehouse(仓库). Most of the buses in the museum date back to around the 1910's.

    With all of these choices, what are you waiting for? IOW Tourism welcomes you!

    The pursuit of longevity has long been on people's minds, prompting an abundance of research on the effects of food and diet on the human lifespan. According to recent research from the UC Irvine Institute, drinking coffee and wine could help you live longer.

    The 90+ Study evaluated more than 1,600 people over the age of 90 for their lifestyle habits and other qualities that might have contributed to their longevity.

    Participants were visited every six months, when they were given various tests. Researchers also collected information about the participants' diets, lifestyles, and medical histories.

    They found out that two of the habits that helped preserve lives the most are drinking alcohol and coffee. "I have no explanation for it," admitted Dr Claudia Kawas, "but I do firmly believe that moderate (适度的) drinking improves longevity." So should we all be drinking more coffee and wine? While that would be great news, the research may not be as definitive as it seems.

    "Most studies about alcohol consumption, including The 90+ Study, are observational, so we can only say that something about drinking is associated with health and longevity," registered dietitian Jennifer Markowitz told The Daily Meal.

    "I'd be curious to see if the coffee and alcohol drinkers shared other important habits or lifestyle factors that might also play into their longevity."

    In other words, it might not be the wine and coffee that's helping people live longer, but the two substances do have some considerable health benefits. "Wine and coffee are packed with antioxidants(抗氧化剂) which are known to protect our bodies from damage caused by free radicals," explained registered dietitian Keri Gans to The Daily Meal. "Research on antioxidants has shown several heath benefits, including the possibility they may lower the risk of type 2 diabetes, improve cognitive function, decrease the risk of dementia, and lower the risk of heart disease."

    Moderate drinking can be beneficial according to other studies—so long as it's moderate.
