Retired nurse Sue Collins was just beginning the second length of her local pool when her morning swim suddenly became anything but a pleasure.

    Two months ago Sue, 69, who has never suffered from asthma or any other breathing problem in the past, suddenly found herself hard for breath.

    “I felt as if my throat and oesophagus (食道) were closing up,” says Sue.

    Sue is convinced the problem is related to the indoor swimming baths. “I spend half the year in Turkey and swim every day outside in a pool or the sea there and never have this problem,” she says.

    She may be right, because although a trip to the pool is the perfect exercise for many, the chlorine (氯气) used to keep the water free from germs can lead to problems.

    But in most cases it's not the chlorine that causes problems, but the by-products formed when chlorine interacts with other substances — and this is mostly due to people not showering before they enter the pool.

    “This then poisons the water for them and for others,” says Dr. Hull. “The chlorine interacts with sweat and urine(尿素) on the skin and forms by-products called chloramines that float above the surface as a gaseous solution that can be inhaled in.”

    Chloramines are heavier than air so hang over the water where they are easily breathed in. Some believe they may cause lung disorders. A Swedish study in 2013 examining the health of 146 workers at 46 indoor pools found that 17 per cent had airway trouble at work — but no problems at home.

    As Dr. Hull says: ‘People need to remember that showering isn't just for them. It is for the greater good.'

    The cultures of the East and the West really distinguish each other a lot. {#blank#}1{#/blank#}

    The origin of the eastern cultures is mainly from two countries: China and India. Both of the two cultures are developed by rivers—the Yellow River in China and the Hindu River in India. {#blank#}2{#/blank#}

When the two mother rivers gave birth to the Eastern culture, another famous culture was brought up on the Mesopotamian Plain-the Mesopotamian Civilization. This civilization later on developed into the cultures of Ancient Greece and Ancient Rome. {#blank#}3{#/blank#} Like the Chinese culture, the European culture also crossed waters. When the British settled down in America, their culture went with them over, the Atlantic Ocean. So the American culture doesn't distinguish from the European culture a lot.

    {#blank#}4{#/blank#} Take the language system for example. In the East, most languages belong to the pictographic language while the Western languages are mostly based on the Latin system. Other causes like human race difference counts as well. But what's more, due to the far distance and the steep areas between the East and West, the two cultures seldom communicate until recent centuries. So they grew up totally in their own ways with almost no-interference (干扰)from the other.

The differences are everywhere. {#blank#}5{#/blank#} But different cultures make the world of 21st century more colorful. The cultural gap should not be the obstacle to the civilization of human being. It ought to be the motivation of our going farther.

    BEIJING—Lu Na thinks that the 4,000 yuan ($630) she spent in traveling to the Republic of Korea(ROK) was worth every penny.

    “Apart from the exotic outfits and tasty kimchi, I really appreciated local people's friendliness and the convenient language environment there,” said the 27-year-old woman, who traveled to the country in October 2011 and came back with bags of fashionable dresses and cosmetics.

    “We have provided many services to Chinese visitors, including free transport cards, handbooks for individual tourists, and more liberal visa policies.”

    “We believe that no country can compare with the ROK in providing services for individual Chinese travelers,” said Zhu Linlin, media manager of the Korea Tourism Organization's Beijing branch.

    Favorable visa policies contribute to the popularity of the ROK as a destination for Chinese tourists. Only a passport and an ID card are needed for a Chinese citizen to get a visa to the ROK.

    However, some suggest that ROK hotels should provide special dining rooms for Chinese customers due to different eating habits. “ROK people often cross their legs when they have meals, but for most Chinese people, especially those who are elderly or fat, it's very hard for them to sit cross-legged without feeling numb.”

    In 1998, China granted the ROK approved destination status, which allowed Chinese citizens to travel to the country in tour groups.

    According to statistics from China Tourism Academy, the number of Chinese tourists visiting the ROK reached more than 2 million by the end of October 2011, up 19. 9 percent compared with that of the same period last year. China recently became the Republic of Korea's main source of foreign tourists in both number and spending.

Dear 17-year-old self,

    When your Laker dream comes true tomorrow, you need to figure out a way to invest in the future of your family. This sounds simple, and you may think it's a no-brainer, but take some time to think on it further.

    I said INVEST.

    I did not say GIVE

    Let me explain.

    Purely giving material things to your siblings（兄弟姐妹） may appear to be right decision. So you buy them a car, a big house, pay, all of their bill. You want them to live a beautiful comfortable life, right？

    But the day will come when you realize that as much as you believed you were doing the right thing, you were actually holding them back.

    You will come to understand that you were taking care of them because it made YOU feel good, it made YOU happy to see them smiling and without a care in the world﹣and that was extremely selfish of you. While you were feeling satisfied with yourself, you were slowly eating away at their own dreams and ambitions. You were adding material things to their lives, but subtracting the most precious gifts of all.

Invest in their future, don't just give.

    Use your success, wealth and influence to put them in the best position to realize their own dreams and find their true purpose. Put them through school, set them up with job interviews and help them become leaders in their own right. Hold them to the same level of hard work and dedication that it took for you to get to where you are now, and where you will eventually go.

    I'm writing you now so that you can begin this process immediately, and so that you don't have to deal with the hurt and struggle of weaning（断绝） them off of the addiction that you facilitated That addiction only leads to anger, hatred and jealousy from everybody involved, including yourself.

    As time goes on, you will see them grow independently and have their own ambitions and their own lives, and your relationship with all of them will be much better as a result.

    Trust me, setting things up right from the beginning will avoid a ton of tears and headache, some of which remains to this day.

Much love

A latest study on people who eat red meat has found they have higher risks of heart disease and early death. The finding goes against other recent research that suggested removing meat from one's diet has few health benefits. The two opposing findings can make it difficult for people to make sense of what can seem to be conflicting messages on food.

Duane Mellor, a dietician at Aston University, and other researchers say that after examining research on the subject, moderation may be the best way forward. "In this case, eating a certain amount of meat, including red meat, is likely to be safe," Mellor said. "However, in the interest of health, reducing meat intake to the recommended less than 70 grams per day would be sensible."

A researcher with ties to the meat industry published a report on the subject in 2019, saying that people should not reduce the amount of red meat they eat. Some experts criticized the findings because they were in conflict with dietary advice from international agencies.

The latest study found that eating two servings a week of red meat or processed meat was linked to a 3% to 7% higher risk of heart disease and also a 3% higher risk of all causes of death. Norrina Allen, a co-leader of the latest study, said the health risk is small but people should try to change their diet. "It's a small difference, but it's worth trying to reduce red meat and processed meat." She added that eating red meat is also regularly "linked to other health problems like cancer."

The World Cancer Research Fund says red and processed meat may cause cancer. It recommends eating red meat with an upper limit of 500 grams cooked weight per week-and "little, if any" processed meat. They said on average, adults should reduce the amount of meat they eat by 50% and they should eat twice as much nuts, fruits, vegetables and beans.
