Manners nowadays in big cities like London are particularly non-existent. It's nothing for a big, strong schoolboy to push an elderly woman aside in the dash for the last remaining seat on a bus, much less stand up and offer his seat to her, as he ought to. In fact, it is saddening to note that if a man does offer his seat to an older woman, it is nearly always one from the older generation.

    This question of giving up seats in public transport is much argued by young men, who say that, since women have claimed equality, they no longer deserve to be treated with courtesy and that those who go out to work should take their turn in the rat race like anyone else. Women have never claimed to be physically as strong as men. Even if it's not agreed, however, that young men should stand up for older women, the fact remains that courtesy should be shown to the old, the sick and the burdened. Are we really so lost to all ideals of unselfishness that we can sit there indifferently reading the paper or a book, saying to ourselves "First come, first served", while a gray-haired woman, a mother with a young child or a cripple stands? Yet this is too often seen.

    Older people, tired and easy annoyed from a day's work, aren't angels, either-far from it. Many an argument or an insulting quarrel breaks out as they feel tired of pushes in the queue and shove(猛推) each other to get on buses.

    If cities are to remain pleasant places to live in at all, however, it seems necessary, not only that communication in transport should be improved, but also that communication between human beings should be kept smooth and polite. Shop assistant won't bother to assist, taxi drivers shout at each other as they dash dangerously round comers, bus conductors pull the bell before their desperate passengers have had time to get on or off the bus, and so on. It seems to us that it's up to the young and strong to do their small part to stop such deterioration(恶化).

    While the U.S. is still debating about getting rid of the penny, Sweden is rapidly moving towards abolishing currency altogether. Though this may sound radical(过激的), it is a natural evolution in this digital society.

    Sweden, which was the first European country to introduce banknotes in 1661, has just been working harder to convince its residents that digital payments are a safer alternative to carrying cash.

    Over the years, the idea has gained popularity with residents, especially the younger generation that is much more comfortable with technology. Today many banks don't even have ATMs and some have stopped handling cash altogether!

    Tickets to ride public buses in most Swedish cities can only be purchased via cell phones. Numerous businesses are also moving towards accepting only digital payments. Even the homeless that sell street paper to make ends meet have to start accepting this mode of payment!

    But despite its growing popularity, some people don't like this radical idea. They include the homeless, elderly people as well as those living in rural areas who are still uncomfortable with mobile phones and computers. But the officials are confident that in the very near future, they will be able to convince everyone to move this safe and more cost-effective payment system.

    Sweden is not the only country trying to abolish paper currency and coins. The movement is rapidly gaining ground in Denmark and Finland as well. In 2014, Israel announced a three-step plan to go cashless and just last week the vendors(小贩)of a popular street in Sydney declared they would stop accepting currency from customers. Whether this phenomenon spreads remains to be seen. But one thing is for sure—With increasingly advanced payment systems being introduced every day, pulling out cash is rapidly becoming “uncool”.

    Being sociable looks like a good way to add years to your life. Relationships with family, friends, neighbours, even pets, will all do the trick, but the biggest longevity(长寿) boost seems to come from marriage or an equivalent relationship. The effect was first noted in 1858 by William Farr, who wrote that widows and widowers(鳏夫) were at a much higher risk of dying than their married peers. Studies since then suggest that marriage could add as much as seven years to a man's life and two to a woman's. The effect holds for all causes of death, whether illness, accident or self-harm.

    Even if the odds are stacked against you (the conditions are not favourable), marriage can more than compensate. Linda Waite of the University of Chicago has found that a married older man with heart disease can expect to live nearly four years longer than an unmarried man with a healthy heart. Likewise, a married man who smokes more than a pack a day is likely to live as long as a divorced man who doesn't smoke. There's a flip side, however, as partners are more likely to become ill or die in the couple of years following their spouse's death, and caring for a spouse with mental disorder can leave you with some of the same severe problems. Even so, the odds favour marriage. In a 30-year study of more than 10,000 people, Nicholas Christakis of Harvard Medical School describes how all kinds of social networks have similar effects.

    So how does it work? The effects are complex, affected by socio-economic factors, health-service provision, emotional support and other more physiological mechanisms(机制). For example, social contact can boost development of the brain and immune system, leading to better health and less chance of depression later in life. People in supportive relationships may handle stress better. Then there are the psychological benefits of a supportive partner.

    A life partner, children and good friends are all recommended if you aim to live to 100.The best social network is still being mapped out, but Christakis says: “People are interconnected, so their health is interconnected.”

    The weather symbol shown for each day in the five day forecast represents the main weather expected on the day in question. The maximum temperature is the highest temperature forecast between dawn and dusk, whereas the minimum temperature is the lowest temperature expected from dusk on the day to dawn the following day. The wind speed and direction are the expected conditions at midday.

    Central Park

    Besides being the city's primary green lungs, Central Park is also a favorite spot for many New Yorkers. It is perfect for sunbathing, going for walks, or doing any outdoor sports. Something that we found curious is seeing so many people running with their babies in prams (婴儿车).
