Tayka Hotel de Sal

Where: Tahua, Bolivia

How much: About $ 95 a night

Why it's cool: You've stayed at hotels made of brick or wood, but salt? That's something few can claim. Tayka Hotel de Sal is made totally ofsalt—including the beds (though you'll sleep on regular mattresses andblankets). The hotel sits on the Salar de Uyuni, a prehistoric dried-up lakewhich is the world's biggest salt flat. Builders use the salt from the 4,633-square-mile flat to make the bricks, and glue them together with a paste(糊) of wet salt that hardens when it dries. When rain starts to dissolve (溶解) the hotel, the owners just mix up more salt paste to strengthen the bricks.

Green Magic Nature Resort

Where: Vythiri, India

How much: About $ 240 a night

Why it's cool: Taking a pulley(滑轮)—operated lift 86 feet to your treetop room is just the start of your adventure. As you look out of your open window, there is no glass! You watch monkeys and birds inthe rain forest canopy(罩篷). Later you might test your fear of heights by crossing the handmade rope bridge to themain part of the hotel, or just sit on your bamboo bed and read. You don't evenhave to come down for breakfast—the hotel will send it up on the pulley-drawn“elevator”.

Dog Bark Park Inn B&B

Where: Cottonwood, Idaho

How much: $ 92 a night

Why it's cool: This doghouse isn't just for the family pet. SweetWilly is a 30-foot-tall dog with guest rooms in his belly. Climb the wooden stairs beside his hind leg to enter the door in his side. You can relax in the main bedroom, go up a few steps of the loft(阁楼) in Willy's head, or hang out inside his nose. Although you have a full private bathroom in your quarters, there is also a toilet in the 12-foot-tall fire hydrant(消防栓) outside.

Gamirasu Cave Hotel

Where: Ayvali, Turkey

How much: Between $ 130 and $ 450 a night

Why it's cool: Experience what it was like 5,000 years ago, when people lived in these mountain caves formed by volcanic ash. But your stay will be much more modern. Bathrooms and electricity provide what you expect from a modern hotel, and the white volcanic ash, called tufa, keeps the rooms cool insummer. (Don't worry— there is heat in winter.)

    Once when I was facing a decision that involved high risk, I went to a friend. He looked at me for a moment, and then wrote a sentence containing the best advice I've ever had: Be bold and brave — and mighty (强大的) forces will come to your aid.

    Those words made me see clearly that when I had fallen short in the past, it was seldom because I had tried and failed. It was usually because I had let fear of failure stop me from trying at all. On the other hand, whenever I had plunged into deep water, forced by courage or circumstance, I had always been able to swim until I got my feet on the ground again.

    Boldness means a decision to bite off more than you can eat. And there is nothing mysterious about the mighty forces. They are potential powers we possess: energy, skill, sound judgment, creative ideas — even physical strength greater than most of us realize.

    Admittedly, those mighty forces are spiritual ones. But they are more important than physical ones. A college classmate of mine, Tim, was an excellent football player, even though he weighed much less than the average player. “In one game I suddenly found myself confronting a huge player, who had nothing but me between him and our goal line,” said Tim. “I was so frightened that I closed my eyes and desperately threw myself at that guy like a bullet（子弹） — and stopped him cold.”

    Boldness — a willingness to extend yourself to the extreme—is not one that can be acquired overnight. But it can be taught to children and developed in adults. Confidence builds up. Surely, there will be setbacks (挫折) and disappointments in life; boldness in itself is no guarantee of success. But the person who tries to do something and fails is a lot better off than the person who tries to do nothing and succeeds.

    So, always try to live a little bit beyond your abilities—and you'll find your abilities are greater than you ever dreamed.

    A couple of weeks ago,my 12-year-old daughter Ella,threatened to take my phone and break it."At night you'll always have your phone out and you'll just type,"Ella says,"I'm ready to go to bed,and try to get you to read stories for me and you're just standing there reading your texts and texting other people,"she adds.I came to realize that I was ignoring her as a father.

    Ella isn't the only kid who feels this way about her parent's relationship with devices.Catherine Steiner-Adair,a psychologist at Harvard,wrote The Big Disconnect: Protecting Childhood and Family Relationships in the Digital Age.For her book,Steiner-Adair interviewed more than 1,000 kids from the ages of 4 to 18.She talked to hundreds of teachers and parents.

    "One of the many things that knocked my socks off,"she says,"was the consistency（一致性）with which children—whether they were 4 or 8 or 18—talked about feeling exhausted and frustrated or mad trying to get their parents' attention,competing with computer screens or iPhone screens or any kind of technology."

    A couple of years ago,my daughter got a laptop for school.And because she was becoming more independent, we got her a phone.We set up rules for when she could use the device and when she'd need to put it away.We created a charging station,outside her bedroom,where she had to plug in these devices every night.Basically,except for homework,she has to put it all away when she comes home.

    Steiner-Adair says most adults don't set up similar limits in their own lives."We've lost the boundaries that protect work and family life,"she says."So it is very hard to manage yourself and be present in the moments your children need you."

    After my daughter's little intervention（介入）,I made myself a promise to create my own charging station.To plug my phone in—somewhere far away—when I am done working for the day.I've been trying to leave it there untouched for most of the weekend.

    Does your older brother think he's cleverer than you? Well, he's probably right. According to a new research published in the journal Intelligence, the oldest children in families are likely to have the highest IQs and the youngest the lowest.

    A number of studies have suggested that IQ scores decline with birth order. In the most recent study, at Vrije University, Amsterdam, researchers looked at men and women whose IQ had been tested at the ages of 5, 12, and 18.

    The results, which show a trend for the oldest to score better than the youngest in each test, involved about 200,000 people. That showed that first-borns had a three-point IQ advantage over the second-born, who was a point ahead of the next in line.

    The order of birth can also affect personality, achievement, and career, with first-borns being more academically successful and more likely to win Nobel prizes. However, eldest children are less likely to be radical(不同凡响的) and pioneering. Charles Darwin, for example, was the fifth child of six.

    Exactly why there should be such differences is not clear, and there are a number of theories on environmental influences on the child.

    The so-called dilution(稀释法) theory suggests that as family resources, both emotional and physical, as well as economic, are limited, it follows that, as a result , as more children come along, the levels of parental attention and encouragement will drop. Another theory is that the intellectual environment in the family favors the first-born who has, at least for some time, the benefit of individual care and help.

    The theory which enjoys the most support is that the extra time and patience that the earlier-borned get from their parents, compared with those arriving later, gives them an advantage.

Can you imagine there being a community where boys and girls growing up together can finally speak different languages? In Ubang Nigeria, it really happens. It's not exactly clear what percentage of the words in the men's and women's languages are different, but there are enough examples to make sentences sound different when spoken by the opposite sex. For "clothing", men use the word "nki", while women say "ariga"; "kitchi" means tree for men, while women say "okweng". These are not just some slight pronunciation differences, but totally different words. "It's almost like two different lexicons (词汇集)," a language expert, Chi Chi Undle said. "There are a lot of words that men and women share in common, but there are others which are totally different depending on your sex. They don't sound alike, and don't have the same letters. They are completely different words."

Interestingly, both men and women are able to understand each other perfectly in Ubang, as both boys and girls grow up around their parents and get to learn both languages, but by the age of 10, boys are expected to speak in the male tongue. It seems that there is a stage the male will reach and he discovers he is not using the rightful language. When he starts speaking the men's language, you know the maturity is coming into him.

No one really knows how or why the double-language tradition of Ubang began. Chi Chi Undie believes the two languages are the result of a "double-sex culture" where men and women operate in two separate spheres (范围) and live in separate worlds that rarely come together. However, she admits this is a weak theory, as the double-sex culture is present in many parts of Africa, where there are no different languages for men and women.

Today, with English words constantly entering the lexicon of young Nigerians, Ubang's two languages are in danger of being lost forever. Worse still, neither the male nor female language is written down, so they both rely on young people passing them down to the next generation.
