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.

    On a cloudless summer day, 13-year-old Charlie Finlayson was ready for a long hike with his father, David.

    Around noon, David was inching his way across a cliff 800 feet above the valley, searching for a line of cracks that would lead them to the top. Charlie stood on a rock a dozen yards to the right as he fed rope to his dad. Reaching up, David missed his step. In the next moment, he heard a sharp crack from above as something larger broke loose.

    When Charlie saw his father sailing through the air alongside the huge rocks that had struck him, he pulled the rope fiercely.

    “Tell me it's OK,” Charlie begged, struggling to control his fear.

    “I think I broke my leg,” David told him. “And we must get off this mountain.” He proposed a plan: Charlie would lower David half a rope length at a time, then lower himself to the same level, and at a new place, begin again.

    As hours passed, they came to the base of the cliff, and David was shaking with cold and exhaustion.

    Worried that David would die if he fell asleep, Charlie kept the conversation going; they talked about past travels. Eventually Charlie allowed himself to catnap, checking on his father each time he awoke. When the sun rose on their camp, Charlie was relieved to see that his father was awake.

    Just after dawn, Charlie headed off on the trail toward the volunteers' cabin 12 miles away, bringing back a helicopter that would carry his father to safety.

    “Charlie's as strong as anyone I know,” says his father, “I'm so proud of him.”

    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.

    Do you ever wonder why trees begin to bud (发芽) earlier in some cities? Scientists finally found the answer but it's not very pleasant. New science suggests a relationship between light pollution and the timing when trees produce buds, which signals the arrival of the spring season.

    Light pollution is defined by the Lighting Research Center as the unwanted consequence of outdoor lighting such as street lights. Excessive (过多的) man-made light at night results in disturbed natural cycles, and also prevents the observation of stars and planets at night. But its effect on the environment goes beyond that.

    By studying some trees, researchers found out that trees that are more exposed to artificial lighting at night bud up to 7.5 days earlier than those at the natural nighttime setting. And they found out that light had a more significant effect than temperature when the buds came out. The early budding may cause problems for insects, which feed on leaves, and the birds which then feed on them in turn. Professor Richard French Constant, who helped lead the research, explained that more than the budding of trees, the study implies the danger to the balance of the ecosystem. “At the moment, caterpillars (毛毛虫) are timed to hatch to make the most of the opportunities to feed on freshly budded leaves, and birds hatch in time to feed on the young caterpillar,” he said.

    Migratory (迁徙的) birds are also negatively affected by light pollution. The glare might confuse them and make them lose their flying sense. The phenomenon might explain why some birds accidentally knock into buildings.

    Such results stress the need to pursue studies that aim to measure the effect of light pollution. If the issue were left to continue, it is estimated that by 2100, spring would begin almost a full month earlier than it does today.
