Valentine's Day, a day traditionally reserved for expressing romantic love, is observed practically all around the world. However, not many people are familiar with Sweetest Day. Actually it is a holiday, especially designed to express love and care for those who were routinely neglected（忽视）by society.

Sweetest Day was the idea of Herbert Birch Kingston, who worked for a company in Cleveland, Ohio. He felt that there were plenty of children, especially orphans and poor kids, who didn't necessarily get the attention they deserved. Thus in 1922, he launched the first Sweetest Day to give out boxes of candy to mainly poor children.

    Since the day picked was the third Saturday in October, this became the traditional time to celebrate Sweetest Day. The tradition was so enjoyed that people often looked beyond kindness to treating their own friends or family to treats on Sweetest Day.

    In the US, Sweetest Day is celebrated primarily in the Northeastern region of the US, still on the third Saturday of October. Yet news of the tradition, which began nearly 100 years ago, has spread to other parts of the country, especially as people who lived in those areas moved elsewhere. People may distribute candy or small gifts to those in patient homes, hospitals, foster homes, or mental institutions, and they may also treat friends and family to little gifts from the heart.

    In keeping with the original tradition, celebrating Sweetest Day should really be most focused on people who ordinarily don't have the good fortune of attention from friends or family, either due to difficult family circumstances or to poverty. This can be a great tradition to start if your community doesn't routinely celebrate the day, and there are many candy manufacturers that are willing to help donate or reduce costs on gifts intended for people in unfortunate circumstances.

    New mercury(汞) threat to oceans from climate change

    Rising temperatures could boost mercury levels in fish by up to seven times the current rates, said Swedish researchers in an article published in Science Journal. They've discovered warming increases levels of the toxin (毒素) in sea creatures. In experiments, they found that extra rainfall drives up the amount of organic material flowing into the seas. This alters the food chain, adding another layer of complex organisms which boosts the concentrations of mercury up the line.

    Mercury is one of the world's most toxic metals, and according to the World Health Organization, is one of the top ten threats to public health. The substance at high levels has been linked to damage to the nervous system, paralysis and mental impairment in children.

    The most common form of exposure to mercury is by eating fish containing methylmercury(甲基水银), an organic form of the chemical which forms when bacteria react with mercury in water, soil or plants. Levels of mercury in the world's ecosystems have increased by between 200% and 500%, since the industrial revolution say experts, driven up by the use of fossil fuels such as coal.

    In recent years there have been concentrated efforts to limit the amount of mercury entering the environment, with an international treaty, called the Minamata Convention, signed by 136 countries in place since 2013.

Researchers hope that the Minamata treaty will be successful and countries reduce the amount of mercury that is being produced. Otherwise this discovery of a previously unknown source could have impacts for human health.

    Other researchers in the field say that the new study highlights important issues that have previously been little known.

     “This work experimentally proves that climate change will have a significant effect of methylmercury budgets in coastal waters and its accumulation in fish,” said Milena Horvat from the Jozef Stefan Institute in Slovenia.

     “This work will also help us understand the formation of mercury in fish and help reduce mercury from emission sources (primarily industrial).”

Multitasking

    What is the first thing you notice when you walk into a shop? The products displayed (展示) at the entrance? Or the soft background music?

    But have you ever notice the smell? Unless it is bad, the answer is likely to be no. But while a shop's scent may not be outstanding compared with sights and sounds, it is certainly there. And it is providing to be an increasing powerful tool in encouraging people to purchase.

    A brand store has become famous for its distinctive scent which floats through the fairly dark hall and out to the entrance, via scent machines. A smell may be attractive but it may not just be used for freshening air. One sports goods company once reported that when it first introduced scent into its stores, customers' intension to purchase increased by 80 percent.

    When it comes to the best shopping streets in Pairs, scent is just as important to a brand's success as the quality of its window displays and goods on sales. That is mainly because shopping is a very different experience to what it used to be.

    Some years ago, the focus for brand name shopping was on a few people with sales assistants' disproving attitude and don't touch what you can't afford displays. Now the rise of electronic commerce (e-commerce) has opened up famous brands to a wider audience. But while e-shops can use sights and sounds, only bricks-and-mortar stores (实体店) can offer a full experience from the minute customers step through the door to the moment they leave. Another brand store seeks to be much more than a shop, but rather a destination. And scent is just one way to achieve this. Now a famous store uses complex man-made smell to make sure that the soft scent of baby powder floats through the kid department, and coconut (椰子) scent in the swimsuit section. A department store has even opened a new lab, inviting customers on a journey into the store's windows to smell books, pots and drawers, in search of their perfect scent.

    Tired of eating at the same boring restaurants? Looking for a change? Here are some restaurants that offer an original restaurant experience. See for yourself which ones you fancy.

    An Exciting Dinner

    Looking for something adventurous? The Archipelago in London is just the thing for you. One of the most popular dishes in this restaurant is crocodile. Yes, you read it correctly, crocodile. If that is not daring enough for you, there are plenty of other dishes on the menu.

    A Restaurant with a View

    Want to enjoy the sights while you're eating? Try the Top of the World restaurant. At about 244 meters above Las Vegas, diners can enjoy a spectacular view of Las Vegas in this revolving restaurant. However, the real adventure starts at the end of the meal. That's when the customers are taken from their seats at ground level to the observation rooms in elevators that travel at a remarkable speed.

    A Theatrical Experience

    Longing for dinner with some drama? Dine with mimes at Mime in Manchester. The service is unique. Your waiter will communicate your order in mime and keep you entertained with performances in between courses.

    An Unusual Setting

    Don't care about presentation? You'll be fine at the Modem Toilet restaurant in Taiwan. The theme of this restaurant is the toilet, and you would be surprised how many people queue up for the experience of eating on toilet seats.

    In modern society, it is usually considered good to be an extroverted(外向的) person. This means that life can be hard for introverted people. Their talents and abilities are often not recognized.

    Some people often try to make introverts more outgoing. They think that being an introvert is a problem. But there is nothing wrong about being an introvert. Introverts are not necessarily afraid of meeting and talking to others. They simply prefer to spend time on their own, away from the crowds. They like reading, writing and taking walks in the countryside. But extroverts need other people. If they spend a lot of time on their own, they get bored. They tend to be impulsive and talk a lot.

    Our society puts a lot of pressure on people to be extrovert, to be outgoing and self-confident on every occasion. Susan Cain, the author of the book Quiet: The Power of Introverts in a World That Can't Stop Talking, has spoken about this problem. "I was nine years old," Cain says. "In my suitcase there were lots of books. This seemed normal to me, because in our family we always read a lot. I thought it would be the same at summer camp. But I was wrong. To create camp spirit, all the children had to sing a cheer every morning. I couldn't understand why. In the evening, I took out a book from my suitcase. But another girl said, 'why are you being so quiet?' The second time I took out a book, the counselor(辅导员) came to see me. She told me to remember the camp spirit and that it was important to be outgoing."

    At work, extroverts often do well. At job interviews, it is usually good to appear extrovert. It suggests that you will be good at the job. But it is wrong to think that only extroverts are good leaders. Introverts work in different ways to extroverts, but they can still do really great things. Darwin, for example, was a quiet, family man. He often took long walks so that he could think clearly. But Darwin's ideas about evolution were revolutionary.

    Introverts must understand that it is perfectly okay to be the way they are. It is not necessary to want to be the center of attention. You don't have to take part in noisy, social activities if you don't want to. And it is not necessary to try to become more outgoing.

    Mother Teresa was born in Yugoslavia on August 27th, 1910. She attended the government school near her home until she was eighteen. At that time, some doctors and nurses from Yugoslavia were working in India, and they often wrote to school about their work. She decided to join them one day.

    When she finished school, she went first to Britain. Then a year later she went to India, where she began to train to be a teacher. After training, she was sent to Calcutta, where she taught geography at a school and soon after she became headmistress. (女校长)

    However, although she loved teaching, in 1946 Mother Teresa left school and went to work in the poor parts of Calcutta. Later she trained to become a nurse in Panta, and then began her work helping the poor and comforting the dying in the streets of the city. Slowly others came to help her, and her work spread to other parts of India.

    Mother Teresa is now a well-known person. Many photos have been taken of her as she traveled the world to open new schools and hospitals in poor countries. In 1979, she was given the Nobel Peace Prize for the lifetime of love and service she has given to the poor.
