Want to add some hours to your day? Ok,you probably can't change the fabric of time. But a new study suggests that theway you feel about your goal can change your concept of time and that somesimple strategies could make you feel less rushed.

In a series of experiments, JordanEtkin, a professor of marketing at Duke, and her co-authors, LoannisEvangelidis and Jennifer Aaker, looked at what happens when people see theirgoals as conflicting with one another. In one, they asked some participants tolist two of their goals that they felt were in conflict, and others simply tolist two of their goals. Those who were forced to think about conflicting aimsfelt more time pressure than those who weren't. In another experiment, the researchersgave participants a similar prompt regarding goal conflict, but this timemeasured their anxiety levels as well as their attitudes toward time. Theyfound that participants who thought about conflicting goals had more anxietythan those who didn't, and that this, in turn, led to feelings of being shorton time.

"Stress and anxiety and timepressure are closely linked concepts," D. Etkin explained. "When wefeel more stress and anxiety in relation to our personal goals, that manifestsas a sense of having less time."

Technological advances that allow peopleto do lots of things at once may increase the fe'eling of goal conflict, shesaid."I think the easier it is for us to try to deal with a lot of thesethings at the same time," She said"the more opportunity there is for us to feel this conflictbetween our goals."She isn't the first to suggest that actual busynessisn't the only thing that can make us feel busy At the Atlantic, Derek Thompson wrote that "as a country, we'reworking less than we did in the 1960s and 1980s." He offered a number ofpossible reasons some Americans still feel so overworked, including "thefluidness ffl±) of work and leisure." As he put it:"The idea thatwork begins and ends at the office is wrong. On the one hand, flexibility isnice, On the other, mixing work and leisure together creates an always-onexpectation that makes it hard for white-collar workers to escape the shadow ofwork responsibilities."

And Brigid Schulte writes in her 2014book Overwhelmed: How to Work, Love, and Play When No One Has the Time thatsome researchers believe "time has no sharp edges. What often matters morethan the activity we're doing at a moment in time, they have found, is how wefeel about it.Our concept of time is indeed,our reality.”

Fortunately, Dr. Etkin and her team didfind ways of making us feel better about time—or, at least, of reducing thenegative influence of goal conflict. When participants performed a breathingexercise that reduced their anxiety, the impact of such conflict on theirperception of time was less pronounced. Reframing anxiety as excitement (byreading the phrase "I am excited!" aloud several times) had a similareffect.

Breathing and reframing may not solveeveryone's time problems—Ms. Schulte writes that some Americans are indeedworking more than they used to. She cites the work of the sociologists MichaelHout and Caroline Hanley, who have "found that working parents combinedput in 13 more hours a week on the job in 2000 than they did in 1970. That's676 hours of additionally paid work a year for a family. And that's on top ofall the unpaid hours spent caring for children and keeping the housetogether." Sometimes, we may feel short on time because we actually are.However, Dr. Etkin believes her findings suggest we may "have the abilityto influence our experience of time more than we think we do."

"We're all going to have times inour lives when our goals seem to be in more conflict than others," shesaid. But with techniques like the ones her team tested, "we really canhelp ourselves feel like we have more time."

Tour Itinerary

    Scotland has long been characterized as a land of romance. It contains ruins of many ancient castles and abbeys，and there is an attractive beauty in its mountains，long deep valleys，and ribbon lakes.Each year those things attract a great number of tourists.

    Numerous islands line the coast.In the north are two large groups，the Orkney Islands and the Shetland Islands.Close to the west coast are the Inner and Outer Hebrides groups，and the islands of Arran and Bute.

    The land may be divided into three regions: the Highlands in the north，the Central Lowlands and the Southern Uplands.

    The Highlands are wild and picturesque(如画的)． A long valley called Glenmore crosses the Highlands from southwest to northeast.

    In the south of the Highlands are the Grampian Mountains，highest in the British Isles. Ben Nevis，the highest peak，rises to 1,243 meters.Ben Lomond rises from the shore of Loch Lomond，Scotland's largest freshwater lake.

    The Central Lowlands run from southwest to northeast and the greatest length is nearly 145 kilometers.The soil here is fertile，and there are four coalfields underlying the area.In the east is Edinburgh，Scotland's historic capital city，and in the west is Glasgow. Almost 90 percent of Scotland's population live in the Lowlands.

    In the Southern Uplands, the hills are generally less than 600 meters high. Their rounded or flat tops are often capped with dark peat(泥炭). Along the slopes are plants like grass and heather(石南花).

    Scientists have found an unexpected use for virtual reality headsets (耳机). The devices (装置), widely used by computer gamers, show pictures that can be used to test the navigational (导航的) skills of people, who were thought to be at risk of dementia (痴呆). Those who do worse in the tests will be the ones more likely to develop Alzheimer's disease later in life, scientists now believe.

    The discovery that the loss of navigational skills was associated with Alzheimer's was made several years ago by Dennis Chan and his colleagues based at several centers in the UK. These studies used computers to test navigational tasks. But now scientists plan to take their tests to a new level with the use of the virtual reality headsets in which wearers are placed in man-made environments through which they must navigate.

    Around 300 people, aged between 40 and 60, will be arranged to participate in the study. Some will have a gene that puts them at risk of the condition or will come from a family with a history of Alzheimer's. Not all will certainly be affected by the disease, however. Chan's project aims to find out who will. Wearing the headsets, participants will be asked to navigate their way through a series of different environments and then remember the details.

    Researchers recently pointed out the significance of a tiny area of the brain known as the entorhinal cortex (an important memory center in the brain). It acts as a center in a widespread brain network that controls navigation. This now appears to be the first part of the brain that seems to be easily harmed by Alzheimer's.

    The goal of the work is to help people as they develop the disease. "So far, drug trials for Alzheimer's have been applied when people have already got dementia, by which time considerable damage to the brain has already occurred," Chan told the Obsenver. "If we can develop drugs and use them earlier, for example, before the disease has spread beyong the entorhinal cortex, then this would have the potential to prevent the dementia."

    At times we all get angry when we are driving. It might be because we are stuck in a traffic jam or stuck behind a very slow driver. It might be because we think another driver has done something very stupid and dangerous. Whatever the reason, it seems that getting angry in a car is something which happens more and more often and there is now a special term for it: "road rage". Some experts even think that road rage is a kind of mental illness! How can we recognize this "illness" of road rage?

There are two kinds of road rage: aggressive driving and aggressive reactions to the way other people are driving. Aggressive driving can take different forms:

    Driving much faster than the speed limit.

    Increasing your speed very quickly.

    Driving very close behind the car in front and sounding the horn or flashing the headlights.

    Changing lanes very suddenly and blocking another car.

    Moving into a parking space where another ear is trying to park.

There are also different reactions to the way other people are driving. These include:

    Making rude signs at people.

    Shouting at people and threatening them.

    Deliberately driving into another person's car.

    Hitting somebody.

    Using a weapon such as a baseball bat, or even a gun or a knife.

    Road rage is certainly not a joke. There have been incidents of road rage which have led to serious injuries and even murder. Experts think that one reason for road rage is that films show a lot of examples of fast and aggressive driving such as car chases where this kind of driving seems to be positive.

    Experts also think that the punishments for dangerous driving are not serious enough. Experience shows that driving problems can be controlled，but it takes a long time. In the UK in the last 30 years, he police have been quite successful in reducing the number of people who drink and drive. They are now working to stop people using mobile phones when they are driving. Let's hope they can have the same success with road rage.

    Whales, like all mammals(哺乳动物),need air, and come to the surface to breathe through a blowhole. A drone(无人机)that floats over the blowholes of humpback whales as they are making annual journey along Australia's east coast is being used by Australian scientists for collecting nasal mucus(鼻腔粘液)of whales.

    Vanessa Pirotta, a biologist at Macquarie University says that nasal mucus indicates the health of the whale. "It is the biological mixture that you see as a whale takes a breath as it surfaces from the water," she said. You can hear sounds of sharp breaths as a whale breathes because, after all, they are animals like you and I. So as they take a breath it is a lot of lung bacteria coming out from their lungs, which we can collect to provide a brief idea of whale health.

    Australian researchers have attached a special dish that is used in scientific tests to a drone which flies through the whale's nasal mist. As a whale comes to take a breath—you can actually see it coming to the surface on really good weather days —the drone then lowers, the dish is then opened, collecting nasal mucus for later research.

    The research could help to solve one of the secrets of another impressive creature of the deep —the Southern right whale. Its numbers have recovered on Australia's west coast since hunting became suppressed but its population on the eastern seaboard remains stubbornly low.

    In the past, studies into whale health had to rely on examining whales that were either killed or those whales that had been trapped on a beach. Drones allow scientists to collect nasal mucus from free-swimming whales to gather information in a safe way.
