October 15th is the Global Handwashing Day. Activities are planned in more than 20 countries to get millions of people in the developing world to wash their hands with soap（肥皂）. For example, donators（捐献者）will give 150,000 bars of soap to schools in Ethiopia.

    Experts say people around the world wash their hands every day, but very few use soap at so-called important moments. These include after using the toilet, after cleaning a baby and before touching food.

    Global Handwashing Day is the idea of the Public-Private Partnership for Handwashing with Soap. Partners include the United Nations Children's Fund, American government agencies, the World Bank and soap makers Unlever and Procter and Gamble. The organizers say all soaps are equally effective at removing disease-causing germ（细菌）. They say the correct way to wash is to wet your hands with a small amount of water and cover them with soap. Rub it into all areas, including under the fingernails. Rub for at least twenty seconds. Then rinse well under running water. Finally, dry your hands with a clean cloth or wave them in the air.

    The Partnership for Handwashing says soap is important because it increases the time that people spend in washing hands. Soap also helps to break up the dirt that holds most of the germs. And it usually leaves a pleasant smell. The Partnership for Handwashing also says washing with soap before eating or after using the toilet could save more lives than any vaccine（疫苗）or medicine. Hand washing could also prevent the spread of other diseases. When people get germs on their hands, they can infect（传染）themselves by touching their eyes, noses or mouths. Then they can infect others.

    Travel is fun and exciting, but it's not if you get sick. You may think, “Not me, I won't get sick on my vacation. ”But for many people, that is what happens.

    A vacation is supposed to be a time for relaxing. But very often it is not.  “What can I do when I am a tourist?” This is what we should often think about.  Usually there are so many places to visit： museums, shops, parks and churches. You may spend most days walking around these places. This can be very tiring. Your feet may hurt.  And you may have a terrible headache after a few hours. If this is what you feel, you should take a rest. Don't ask your body to do too much. A tired body means a weak body. And a weak body can make you get sick easily. Just sit down for a few hours in a nice spot. In good weather, look for a quiet park bench. Or you can rest at a café. You can learn a lot by watching people when you have a rest.

    Sleep is also important. If you want to stay healthy you need enough sleep.  You may have trouble sleeping at night when you travel. Your hotel room may be noisy, or the bed may be uncomfortable.  If that is true, don't be afraid to change rooms or hotels. You may not get enough sleep for another reason. You may want to stay out late at night. In many cities the night life can be very exciting. Then you should plan to sleep for an hour during the day. That extra hour can make a big difference.

    Finally, if you want to stay healthy, you must eat well. That means eating the right kinds of foods. Your body needs fresh fruit and vegetables, and some meat, milk or cheese. When you are in a new country you may want to try new foods but you need to be careful about how much you eat. Lots of rich food is not very good for you.

    The skin under the eyes is delicate, which is why it sometimes appears sunken and has darker coloring than elsewhere on the face. Aging and health problems play a role in sunken eyes but other factors can contribute, so it may affect younger people as well.

Dehydration

    The most common cause of sunken eyes is dehydration, or not having enough water in the body. Consuming too much coffee, soda, and prepackaged drinks may increase production of urine(尿液), which may lead to dehydration.

    Vitamin shortages

    Shortages of vitamin C, vitamin K, and iron can cause eyes to become sunken. Vitamin C helps with absorbing iron and decreasing bruising(瘀斑), while vitamin K is responsible for blood thickening, causing unhealthy skin. Easy bruising and unhealthy skin will result in sunken eyes.

    Weight loss

    Most people tend to lose weight in their face first. Sometimes, the weight loss is sudden enough to make blood vessels(血管)below the eyes easy to see, and the skin clear, producing the appearance of sunken eyes. Sudden weight loss may also cause nutritional shortages, which can lead to sunken eyes.

    Not enough sleep or poor quality sleep can cause sunken eyes and a person's DNA or the habit of smoking can also contribute to sunken eyes. Most cases of sunken eyes relate to the quality of an individual's nutrition and healthy living. When these causes are corrected, sunken eyes can be resolved without further treatment. This means that causes can be avoided or treated in good time to prevent the recurrence of sunken eyes.

    I began cycling in 2004 when I was a poor student. It was dangerous, sure, but cycling is the fastest, cheapest point-to-point form of transport in Melbourne. I own a car now, but that's just for transporting the baby or groceries.

    I hate driving. So it's been quite encouraging watching the growth in cyclist numbers over the past decade. It is said that over 10,000 cyclists enter the CBD (Central Business District) each day, taking pressure off public transport. But as more people take to cycling as a way of transport, the number of cyclists seriously injured or killed keeps increasing. And that is a sign that our infrastructure (基础设施) is still not good enough.

    Melbourne was once a dream for cyclists—flat, long, wide roads, with plenty of paths along rivers. Now, cycling can be deadly, with roads taken up by cars. I have a friend who broke her back and was lucky to escape death and others with broken bones. In my time riding, I've been forced off the road by a truck, cut off by four-wheel drives, and told to get off the road. Drivers are a particularly rude to cyclists. And that's a sign of exactly one thing: inadequate infrastructure.

    We shouldn't need to be taught how to coexist in the same narrow space. Drivers and cyclists should be kept apart. Designing bike paths so riders are channelled between moving cars and parked cars is deadly. All it takes is one daydreaming driver to fling open the door and you are gone. That's what happened to the young university student James.

    This year, there are to be new cycling lanes (车道) built on Glen Road, where James died in 2010. But these lanes are not safe. Cyclists must still pass between two rows of cars.

    Oxford and Cambridge have now decided to remove the words CAN'T and IMPOSSIBLE from their dictionary. Jessica Cox, 25, a girl born without arms, stands inside an aircraft. The girl from Tucson, Arizona got the Sport Pilot certificate lately and became the first pilot licensed to fly using only her feet. Jessica Cox of Tucson was born without arms, but that has only stopped her from doing one thing: using the word "can't".

    Her latest flight into the seemingly impossible is becoming the first pilot licensed to fly using only her feet.

    With one foot manning the controls and the other delicately guiding the steering column, Cox, 25, soared to achieve a Sport Pilot certificate. Her certificate qualifies her to fly a light-sport aircraft to altitudes of 10,000 feet.

    "She's a good pilot. She's rock solid," said Parrish Traweek, 42, the flying instructor at San Manuel's Ray Blair Airport. Parrish Traweek runs PC Aircraft Maintenance and Flight Services and has trained many pilots, some of whom didn't come close to Cox's abilities.

    "When she came up here driving a car," Traweek recalled, "I knew she'd have no problem flying a plane."

    Doctors never learned why she was born without arms, but she figured out early on that she didn't want to use prosthetic devices. So, the next time you are ready to tell yourself, "I can't possibly..." remember this amazing young woman and change your vocabulary.

    On a recent spring morning. Susan Alexander, a retired government intelligence analyst, left her Maryland home, climbed into her Volkswagen Passat and drove about three miles to pick up two strangers. She battled rush-hour traffic on the Capital Beltway and George Washington Memorial Parkway before dropping them off at Reagan National Airport. She didn't earn a cent for her trouble, and that was the point.

    Alexander is a member of the Silver Spring Time Bank— one of more than 100 such exchanges around the world trying to build community by exchanging time credits for services instead of dollars and cents. "I have time," she said. "I like giving the gift of time to other people."

    In Alexander's case, passengers Mary and Al Liepold were grateful for the ride, but it wasn't charity. Mary, a retired writer and editor for nonprofit organizations, used time credits she banked for editing work and baking. Senior citizens who don't drive, the Liepolds cashed in their credits to catch a flight to Montreal for a five-day vacation.

    Without money changing hands or shifting between virtual accounts, the airport drop-off was more like a coffee party than a taxi ride. Driver and passengers chatted about projects they've completed for the time bank, and no one raised an eyebrow when Mary said she likes "to avoid the conventional economy."

    "The beauty of this is that you make friends," Mary Liepold said. "You don't just get services."

    The Silver Spring Time Bank formed in 2015 and has about 300 members, said co-founder Mary Murphy. Last year, she said, l,000 hours were exchanged for basic home repairs, dog walking, cooking and tailoring, among other services, without the exchange of money." You get to save that money that you would have spent," she said. "You get to meet somebody else in your community and get to know that person. That's a bonus that's part of an exchange."

    A deal performed partly to make friends would seem to go against classical economics and one of Benjamin Franklin's most memorable sayings: "Time is money." To those at the forefront of modern time-banking, that is the appeal.
