The Healthy Habits Survey(调查)shows that only about one third of American seniors have correct habits. Here are some findings and expert advice.

    1). How many times did you brush your teeth yesterday?

    Finding：A full 33% of seniors brush their teeth only once a day.

    Step：Remove the 300 types of bacteria in your mouth each morning with a battery-operated toothbrush. Brush gently for 2 minutes, at least twice a day.

    2). How many times did you wash your hands or bathe yesterday?

    Finding：Seniors, on average, bathe fewer than 3 days a week. And nearly 30%wash their hands only 4 times a day-half of the number doctors recommend.

    Step：We touch our faces around 3,000 times a day-often inviting germs(病菌)to enter our mouth, nose, and eyes. Use toilet paper to avoid touching the door handle. And, most important, wash your hands often with hot running water and soap for 20 seconds.

    3). How often do you think about fighting germs?

    Finding：Seniors are not fighting germs as well as they should.

    Step：Be aware of germs. Do you know it is not your toilet but your kitchen sponge(海绵)that can carry more germs than anything else? To kill these germs, keep your sponge in the microwave for 10 seconds.

    Drug companies have spent billions of dollars searching for therapies to reverse or significantly slow Alzheimer's disease, but in vain. Some researchers argue that the best way to make progress is to create better animal models for research, and several teams are now developing mice that more closely imitate how the disease destroys people's brains.

    The US National Institutes of Health (NIH), the UK Dementia Research Institute and Jackson Laboratory (JAX) - one of the world's biggest suppliers of lab mice - are among the groups trying to genetically design more suitable mice. Scientists are also exploring the complex web of mutations(突变) that influences neurological (神经学的) decline in mice and people.

    "We appreciate that the models we had were insufficient. I think it's sort of at a critical moment right now." says Bruce Lamb, a neuro-scientist at Indiana University ~ho directs the NIH-funded programme.

    Alzheimer's is marked by cognitive impairment(认知损伤) and the build-up of amyloid-protein plaques (淀粉样蛋白块) in the brains of people, but the disease does not occur naturally in mice. Scientists get around this by studying mice that have been genetically modified to produce high levels of human amyloid protein. These mice develop plaques in their brains, but they still do not display the memory problems seen in people.

    Many experimental drugs that have successfully removed plaques from mouse brains have not lessened the symptoms of Alzheimer's disease in people. One focused stumble came last month, when three companies reported that their Alzheimer's drugs had failed in large, late-stage clinical trials. Although the drugs successfully blocked the accumulation of amyloid protein in mice, they seemed to worsen cognitive decline and brain shrinkage in people.

    The drive for better mouse models comes as genomics studies are linking the most common form of Alzheimer's to dozens of different genes. This diversity suggests that each case of the disease is caused by a different combination of genetic and environmental factors. "There is no single Alzheimer's disease," says Gareth Howell, a neuro-scientist at Jackson Laboratory (JAX) in Bar Harbor, Maine.

    Howell argues that scientists' reliance on lab mice with only a few genetically engineered mutations might have limited research. His own work suggests that in mice, just as in people, genetic diversity plays a part in determining how Alzheimer's develops.

    We're reading a book or opening an envelope when, all of a sudden, there's a sharp pain on our finger. You see a little bit of blood and realize you've just gotten a paper cut.

    Dr. Hayley Goldbach, a resident dermatologist at UCLA Health, spoke about why paper cuts are so jagged, how the element of surprise leaves us in more pain and how to make sure they heal quickly.

    Dr. Goldbach explained that one reason paper cuts hurt so much is where they occur: primarily on the finger. We have nerve endings all over the body," she said. "In places where there is refined movement and sensation--like the lips or tips of the fingers-they have a high density of nerve endings." These nerve endings are known as nociceptors and they send signals to the brain about things that could cause a break in the skin, such as extreme hot or cold temperatures and chemicals.

    Another reason why paper cuts hurt so much is that you're using your hands throughout the day meaning that the wound is constantly getting opened. "You often get paper cuts on the pad or the tip of the finger, different from where you'd get a knife cut," said Dr. Goldbach. "It's hard not to use your hands, so there's constant pressure on the wound without u chanee for it to heal."

    "The paper itself is another reason why these superficial cuts leave us in so much pain. Paper might look and seem smooth but, if you study it under a microscope, the edge is actually jagged." Paper is quite sharp jagged-it's a bit of serrated edge," said Dr. Goldbach."It cuts you pretty quickly before you have the chance to realize it."

    Additionally, paper cuts are quite shallow, which makes them even more annoying to deal with.

    Dr. Goldbach added that there are mental and emotional elements that cause paper cuts to hurt more than other cuts. "There's the psychological element of surprise, and it happens so quickly that you don't have time to withdraw your hand "she said" With some other injuries, you feel pressure so you have time to react."

    She also added that because we don't expect to hurt ourselves while working with paper, the surprise of cuts leaves us in further pain. "We tend to be careful with a knife-you're being careful on purpose: because you know there: s a danger, "said Dr Goldbach. While we are careful with knives, we are not so careful with paper.

Four Habits to Help You Succeed

    Nobody would like to experience failure. We all want to succeed. For those who have tried and failed, success seems difficult to understand. {#blank#}1{#/blank#}

    • Know your values.

    The traditional tent cities at festivals such as Glastonbury may never be the same again. In a victory of green business that is certain to appeal to environmentally-aware music-lovers, a design student is to receive financial support to produce eco-friendly tents made of cardboard that can be recycled after the bands and the crowds have gone home.

    Major festivals such as Glastonbury throw away some 10,000 abandoned tents at the end of events each year. For his final year project at the University of the West of England, James Dunlop came up with a material that can be recycled. And to cope with the British summer, the cardboard has been made waterproof.

    Taking inspiration from a Japanese architect, who has used cardboard to make big buildings including churches, Mr. Dunlop used cardboard material for his tents, which he called Myhabs.

    The design won an award at the annual New Designers Exhibition after Mr. Dunlop graduated from his product design degree and he decided to try to turn it into a business.

    To raise money for the idea, he toured the City's private companies which fund new businesses and found a supporter in the finance group Mint. He introduced his idea to four of Mint's directors and won their support. Mint has committed around ￡500,000 to MyHab and taken a share of 30 per cent in Mr. Dunlop's business. The first Myhabs should be tested at festivals this summer, before being marketed fully next year.

    Mr. Dunlop said that the design, which accommodates two people, could have other uses, such as for disaster relief and housing for the London Olympics.

    For music events, the cardboard houses will be ordered online and put up at the sites by the Myhab team before the festival-goers arrive and removed by the company afterwards. They can be personalized and the company will offer reductions on the expense if people agree to sell exterior(外部的) advertising space.

    The biggest festivals attract tens of thousands of participants, with Glastonhury having some 150,000 each year. Altogether there are around 100 annual music festivals where people camp in the UK. The events are becoming increasingly environmentally conscious.

    Multitasking-doing several things at a time-was once applauded as the best way to work. But does it actually help you get things done, or does it make you less effective?

    {#blank#}1{#/blank#}If you can actually do two or more things at one time, that clearly saves time.{#blank#}2{#/blank#}And it can fill time that would otherwise he spent poorly.

    However, a growing body of research shows that multitasking is not as productive as it appears. It turns out that when most people multitask, they don't actually focus on more than one thing at a time.{#blank#}3{#/blank#}But changing your focus constantly uses mental energy that could he spent working. It also causes you to take longer and make more mistakes. In addition, it creates stress. People who try to multitask often end up feeling more anxious and less peaceful than people who don't.

    {#blank#}4{#/blank#}A very small group of people-about two percent of the population-excel at multitasking. These people, called supertaskers, are able to work on several things at once without their performance suffering. But experts caution: supertaskers are very rare. The majority of people who think multitasking makes them more productive are fooling themselves.

    If you do want to multitask, productivity experts recommend doing it carefully.{#blank#}5{#/blank#}

A. There are some exceptions to the no-multitasking vile.

B. Instead they switch back and forth between concentrating on two or more tasks.

C. Doing things one at a time usually helps people produce better work.

D. To some people, the advantages of multitasking seem obvious.

E. Multitasking actually works against the goal of getting things done.

F. It might also make you feel productive, which can in turn make you happy.

G. Pair a mentally challenging task with a physical task you don't have to think about.
