It's official. Denmark—as well as being the world's best country to live in for women with the second-happiest people and one of the best healthcare systems in Europe—has the most contented babies. Or, at least, the ones who cry the least. According to research published in the Journal of Pediatrics, Danish, German and Japanese babies cry the least, while British, Canadian and Italian babies cry the most.

    “I'm not surprised,” Danish parenting expert and co-author of The Danish Way of Parenting Jessica Alexander tells me. “The first year of a child's life is considered so important in Denmark. Danish parents are much less stressed because they get good maternity and paternity leave (孕产假). The atmosphere is much calmer and, if mothers are getting more time off, that goes hand in hand with less stress, more contact, more routines and less crying.” She pauses before throwing in a final tip: “Oh, and Danish babies sleep outdoors a lot.”

    In Denmark, a woman is given four weeks pregnancy leave followed by 52 weeks of paid leave that can be shared between parents. And Alexander thinks there is another important reason why Danish babies cry less: breastfeeding. “It's just the done thing in Denmark,” she says of a country that has the world's highest breastfeeding rates. “In other countries, there are continual discussions about whether you should or shouldn't breastfeed. In Denmark, breastfeeding has never gone out of style. And everyone does it for a year.”

    For Iben Sandahl, Alexander's co-author, it comes down to the Danish attitude to life in general. “We are an honest and pure people,” she tells me. “We are surrounded by social support and are less likely to become angry, sad or annoyed when our babies are crying. And we are good at embracing (拥抱) all kinds of feelings, so we aren't scared. Instead, we try to connect with the babies when they cry. It's how babies communicate and it's about trying to understand it.”

    Well, parents, surprise! Lots of us are using Twitter and Facebook to thumb rides, and not just to school. It's awkward to be refused when you call a friend and ask for a ride. But with Twitter, you just look for other people heading the same way.

    It may sound risky, so many teens stay within their own social circles to find rides, and don't branch out beyond friends when asking on Twitter just like me, but to some young people, especially those taking longer trips, stranger danger is less of a concern.

    “I think the digital connection of young people is really important, because younger generations grew up sharing things on line, sharing files, photos, music, etc, so they've been very used to sharing,” said Juliet Schor, a sociology professor at Boston College.

    The sharing economy got big during the recession (经济衰退), allowing people to access more goods, services using technology and even to share costs. And that technology, for me, is what the car was for my mom, a gateway to more freedom, like what my friend Earl says, “The symbol of freedom isn't the car any more because there's technology out there connecting you to a car.”

    According to the researchers at the University of Michigan, 30 years ago, eight in ten American 18-year-olds had a driver's license compared to six in ten today. So it's not that surprising that on my 16th birthday I wasn't rushing to get a license but an iPhone.

“Driving, for young people, does mean they have to disconnect from their technology, and that's a negative. So if they could sit in the passage side and still be connected, that's going to be a plus.” Schor continued.

    To me, another plus is that ridesharing represents something, something much bigger than trying to save money. I see it as evidence that people still depend on each other. My generation shares their cars and apartments the way neighbors used to share cups of sugar. For the system to work, some of us still need our own cars. But until I get my own version of the silver Super Beetle, you can find me on Twitter.

    Can you imagine four hours of your day getting to and from work? For the last eight years, Jo Meade rode her bike each Sunday on a 16-mile round trip to her job washing dishes. It took more than an hour each way. Other days of the week she would spend two hours on three buses from her apartment to get to the other work, for a four-hour round trip.

    That was the “before” part of her life. The “after” part of her life was started by the community Police Officer Trevor Arnold, who delivered a used car to her with the help of a car dealer and other donors.

    Arnold, who spotted Meade, red and sweaty, riding her bike in the worst heat this summer, decided he would het her a car. He intended to quietly buy her a used car out of his own pocket so he turned to his friend Kody Slaght, a car salesman to ask about a car priced $1,000. That wasn't enough for a reliable ride, Slaght said, but the dealership said they would find a good car for her at a good price. Soon others were donating. Slaght and Arnold wouldn't say how much the car cost, but the value is about $4,000.

    Arnold said he was motivated by Meade's work ethic（职业道德）to help. “I see a lot of hardworking people nut that's when they are at work. Can you imagine spending four hours of your day getting to and from work?” he said.

    Meade's boss said she was awesome and really reliable when she worked and she got along with others. “She's willing to rise the three buses to get in here on her day off if we need her too.”

    Meade said she was planning to buy a car, “but I haven't been able to afford it,” she said. “Trevor, he is a very good guy. I did not expect this.”

    In the book The Best Little Girl in the World, Kessa has a serious eating disorder (进食障碍) called anorexia nervosa. But she is not alone. Many people have this eating disorder.

    In the beginning of her story, Kessa is a normal 15-year-old girl. She is good at many things, especially dancing. She has danced for many years and loves it. One day her dance teacher tells her to continue eating right, but maybe lose a few pounds. Once Kessa hears this, she takes things too far. Instead of cutting down on snacks and junk food, she decides not to eat at all. She does not eat breakfast, lunch, or dinner. She begins losing weight and becomes slimmer (更加苗条的) and slimmer. But she loses weight to a point where she is unhealthy.

    As her poor eating habits continue, her parents start getting as much help as possible to cure (治疗) their beautiful daughter. But it is just as hard for Kessa's parents to deal with her disorder as it is for her.

    Every day she exercises to lose more pounds and plans what and when she will eat. Her parents try everything, but Kessa decides not to have any fat on her body.

    Kessa's doctor and parents finally take her to the hospital. She is now so thin that she can hardly walk. There, she is given good care.

    In the rest of the book, Kessa goes through a lot of trouble in order to cure her eating disorder. This book, I think, can help to prevent people from doing this to themselves. It shows the trouble that people go through just to be slimmer, and all the terrible things they must experience to be cured. It is a book I think every teenager should read.

Fishy Weather Conditions

    Laj amanu，Australia，is a dry little town，sitting right on the edge of the Tanami desert. Can you imagines How surprised were people when live fish rained down on them from a dark gray cloudy. It happens that there are similar cases in England and Honduras.

    How do clouds make fishy. The simple answer is that they don't. There is a particular weather phenomenon(现象)called a waterspout. A waterspout is just like a tornado，only it forms above oceans，lakes，or rivers. Like a tornado，a waterspout moves in a circle at high speeds. When it moves above the water，it tends to carry the fish with it，as well as frogs or other small plants or animals.

    Scientists couldn't work it out at first. To make matters stranger still，the fish in Honduras were very much alive when they rained down to the ground，but they were all blind. In England and Australia，it rained fish and snakes，and none were blind. It was difficult to puzzle out，but the blind fish gave them a place to start.

    Scientists knew that some fish that lived in deep，underground caves with no light sources often lost their eyesight. So when blind fish rained down on Honduras，scientists began to connect some dots. Clearly，these particular fish were pulled from an underground water source by force.

    It has rained fish on every continent，and each time，people have tried in various ways to explain this strange phenomenon. Historically，villagers thought the “fishes from the heavens” might be answers to prayers for food. Others suggested that floods overran river banks and oceans，leaving the fish on the city streets. No scientist had actually seen the rain as it occurred，only the fish left on the ground. But in 1990，a National Geographic team happened to be in Honduras when the Rain of Fishes began. They recorded what was happening and made history by finally proving that the fish really did fall from the sky.

    This huge breakthrough wasn't just a spot of good luck. It changed thousands of years of myths and legends into true stories and provided scientific explanations for how fish came to live in deep caves. It explained ancient cave paintings and shed new light on how species have spread over time. It turned out to be a lot more than just a little fishy weather.
