There was good news last week for people who struggle to get eight hours of sleep a night: they may not need so much shut-eye after all.

    Researchers from UCLA and elsewhere looked at sleep habits of remote hunter-gatherers in Tanzania, Namibia and Bolivia — groups with pre-industrial lifestyles whose sleep patterns are believed to reflect those of ancient humans. The researchers found that, on average, members of each group sleep a bit less than six and a half hours a night.

    The study, published in the academic journal Current Biology, indicates that “natural” sleep is less than eight hours a night and that modern society's numerous electronic distractions (分心) aren't necessarily to blame for people getting just six or seven hours of sleep.

    “The story that often gets out is that if you sleep for less than seven hours, you're going to die early,” he told me. “That's not true.”

    Yet Americans are addicted to getting more sleep — and on turning to medical shortcuts to help them.

    According to the Centers for Disease Control, as many as 70 million U.S. adults suffer from sleep disorders or sleeplessness. Only a third of Americans get the government's recommended seven to nine hours of sleep a night.

    About 9 million American adults use sleeping pills to help get a good night's rest, the CDC found. Siegel said the number of people relying on medicines “has gone up rather rapidly since then.”

    Industry consulting firm Global Data estimates that worldwide sales for sleeplessness medicines will run about $1.4 billion next year and reach $1.8 billion by 2023, recovering from lower sales in recent years because of cheaper generics(仿制药) hitting the market.

    Dr. Roy Artal, a sleep specialist in West Los Angeles, said it's understandable that busy people in today's go-go world would turn to medicines to speed up the sleep process. But all they're doing is building a reliance on powerful drugs for relatively little improvement.

    “There's no magic pill that makes us sleep when we want and wake up when we want,” Artal said. “The effects of sleeping pills tend to be modest.”

    He and other experts say the answer to sleeplessness isn't to be found in a pill bottle. It's in what's called “sleep hygiene (保健).”

    Some people were eating and drinking in a coffee house. A young woman was sitting alone at a table. She was wearing a beautiful diamond necklace. There was an ugly man at a table not far from her. He was looking at her necklace all the time.

    Suddenly the lights went out. The coffee house was in darkness. The woman started to shout. She was very frightened. A few minutes later the lights came on again. The woman was crying. Her necklace was missing.

    The manager quickly closed all the doors. He telephoned the police. No one could get out of the coffee house. The policemen soon came. The police inspector told his men to search everyone. The necklace was not on anyone. They then searched the whole coffee house. The necklace couldn't be found.

The police inspector then looked at the faces of all the people in the coffee house. He saw the ugly man and looked at the man carefully. He went up to the man and picked up the bowl of soup that was on his table. He then poured the soup into a glass. The necklace fell out. The policemen caught hold of the man and took him away. The young woman was happy to get back her necklace.

    Saber Miresmailli was on vacation in London when, caught in a bit of traffic on London Bridge, he decided to take a photo of Tower Bridge.

    “I noticed the couple,” he said. “At that moment, I did not see anyone from the wedding party or a photographer with the couple, so I took several pictures. Usually, my pictures are not very good given the fact that I don't use flash and I don't stop to compose (构图)-so when we get back after two weeks, I was very surprised to find this one turned out so well.”

    Miresmailli said, “I thought to myself, if it was me getting married, I would have wanted the picture.” So he posted the photo on Facebook and attached a few friends with the hope of finding the couple and passing them the picture. What happened next, he said, “was crazy”. “I received more than 2,000 requests from perfect strangers and lots of positive and negative emails.” Until this afternoon, almost 230,000 people had shared his Facebook post on the photo.

There's also been an uncertain identification of the couple. It's likely that their names are Laura and James. “If it's the right couple,” Miresmailli said, “they are on their honeymoon in Bali and have no idea about the photo. I believe they will be shocked to find out about their fame.”

    Miresmailli said he's been drowned by the interest in the photo. “I just want to give them their picture and go back to work and tend my tomatoes,” he said.

    Before the 1830s, most newspapers were sold through annual subscriptions in America, usually $8 to $10 a year. Today $8 or $10 seems a small amount of money, but at that time these amounts were forbidding to most citizens. Accordingly, newspapers were read almost only by rich people in politics or the trades. In addition, most newspapers had little in them that would appeal to a mass audience. They were dull and visually forbidding. But the revolution that was taking place in the 1830s would change all that.

    The trend, then, was toward the "penny paper" ­a term referring to papers made widely available to the public. It meant any inexpensive newspaper; perhaps more importantly it meant newspapers that could be bought in single copies on the street.

    This development did not take place overnight. It had been possible(but not easy)to buy single copies of newspapers before 1830, but this usually meant the reader had to go down to the printer's office to purchase a copy. Street sales were almost unknown. However, within a few years, street sales of newspapers would be commonplace in eastern cities. At first the price of single copies was seldom a penny­usually two or three cents was charged­and some of the older well­known papers charged five or six cents. But the phrase "penny paper" caught the public's fancy, and soon there would be papers that did indeed sell for only a penny.

    This new trend of newspapers for "the man on the street" did not begin well. Some of the early ventures(企业)were immediate failures. Publishers already in business, people who were owners of successful papers, had little desire to change the tradition. It took a few youthful and daring businessmen to get the ball rolling.

    Our plan was to drive into Cambridge, catch the 7:34 train to Liverpool Street Station, then to separate and meet again for lunch. We should have arrived at Liverpool at 9:19, but due to a typical London fog, the train had to move along so slowly that it was not until 10:30 that it got there. In spite of our late arrival, Joan, my wife's sister, decided that she would go to see the Crown Jewels in the Tower of London while we went shopping. It was only after her sister had disappeared into the fog that my wife realized that we hadn't decided where we should meet for lunch. Since I had our three tickets for the concert in my pocket, this was indeed a problem. There seemed to be nothing we could do except taking a taxi to the Tower of London, and try to find her there. Needless to say, we didn't find her.

    It was now one o'clock, and the concert began at 2:30. "Perhaps she will think of waiting outside the concert hall," suggested my wife hopefully. By this time the fog was so thick that road traffic had to stop, and the only way to get there was by underground railway. Hand in hand we felt our way along the road to where we thought the nearest station should be. An hour later we were still trying to find it. Just as I was about to lose my temper completely when we met a blind man tapping his way confidently through the fog. With his help we found Tower Hill tube station just fifty yards down the road.

    By now it was far too late even to try to get to the concert hall before the performance began at 2:30, so we decided to return to Cambridge. It took seven long hours instead of the usual two to make that journey. Nor were we able to get any food and drink on the train. Tired and hungry we finally reached home at ten, opening the door to the sound of the telephone bell. It was Joan; she had seen the Crown Jewels, had managed to get another ticket for concert, and had had a wonderful dinner at a restaurant near the hotel where she decided to stay for the night. Now she was ringing to discover whether we had had an equally successful day.

Christmas in the United States is traditionally a time of gift-giving and family gatherings. But small towns across the country have their own traditions.

Middleburg, a small town in the state of Virginia, is known for its horses. For more than 50 years, Middleburg has organized a yearly Christmas parade. Men and women ride horses through the woods and fields. They follow hunting dogs as they search for a wild fox. But first, these hunters ride in the yearly parade, wearing their bright red hunting clothes and hats.

John Hale, a citizen of Middleburg says many city people visit his town." We have a lot of people from an urban area that come to visit, but it incorporates a lot of the old traditions." The night-time hayride is one such tradition. Small groups gather under the moonlight on an open wagon (四轮马车) filled with hay (干草). The passengers sing as farm horses pull the wagon slowly across the fields.

There are some newer traditions, too. Trey Matheu works at the nearby Salamander Resort. He says a visit to Middleburg is a chance to slow down for a day. He says Middleburg can be a calming, peaceful place without tension.

"Middleburg is an opportunity to take a step back, to take a deep breath, and understand that even though life is moving on at a very fast pace, there's really an opportunity where you're allowed to step off for a little bit."

Parade organizers say more than 13, 000 people attend even in below freezing weather. But if you ask, you will hear many different reasons why people come to watch the parade:

"I come here because I'm from a small town. I like how everybody comes together."

"I live right down that street, right there. And that's my dog."

Middleburg looks its best at Christmastime. That may be why so many people return each year.
