It has been several weeks since we tookour daughter to college and she seems to be adjusting  well after a short period of homesickness.For us, though, it's another story. Like most parents, I love checking in on mychildren at night. But now she's gone, and I find nighttimes the hardest. Imiss her most at night.

    In my neighborhood, most of the parentswhose kids are off to college are dealing with similar melancholy. Myhusband is filled with anxiety. One friend talked about getting this sickfeeling in her stomach as she prepared for the college drop-off. We complainedthat many of us were too busy to truly enjoy being with our children while wehad them.

    For us moms, seeing Toy Story 3 onlymade the sadness worse as we watched the character Andy, who is the same age asour kids, say goodbye to his childhood as he prepares to leave for college. Andit's not just “first-time” parents like me. Two moms who have kids already wellinto college said the separation didn't get any easier. “You feel likesomething has been taken away from inside you,” said one of them.

    I imagine things will get easier withtime, especially as I see my daughter adjust to college life. Meanwhile, as Ikeep my cell phone close to me in bed and text my daughter goodnight and sweetdreams every night, I like to think at messages serve as a night light thatkeeps her safe.

    It seems the more time we have, the longer we put off living the life we see in our heads, because we feel like we've got some time to kill.

    I know where you think I'm going with this, and I also know you've heard it all before: seize the day, make the most of it, live life to its fullest, and so on. But that's the problem. You've heard it all before. These ideas have their impact and have become a cliché. Luckily, that's not my thing.

    The real answers wake something up inside you. They make you think. That's what I want to give you today, the story of Bobby Darin, which wakes you up to the truth.

    If you haven't heard of the man, I know you've heard his songs. Among his many hits are Mack the Knife, Beyond the Sea, Dream Lover, and Splish Splash.

    If seven years, Darin had several top ten hit songs, was nominated(提名) for four Grammy Awards (winning two), nominated for four Golden Globes (winning one), and even nominated for an Oscar.

    So what was his secret?

    All his life, Darin had a heart condition that developed from a childhood illness. The doctors at the time said he would be lucky to live to 16. In other words, his time was limited. And this was secret. He knew the truth. He knew that we all have such a hard time accepting: Life is short. You can't just say it; you can't just hear it. You have to know it, believe it, and feel it. Because Darin knew his time was limited, he packed as much life as he could into the time he had. But he had an unfair advantage. He knew, without a doubt, his time was limited.

    There was no fooling himself, no putting it off. It was now or never.

    It is good to get in touch with your inner child from time to time, and obviously some people are willing to pay big money for the chance to do so in a proper environment. A Brooklyn-based adult preschool is charging customers between $333 and $999 for the chance to act like a kid again.

    At Preschool Mastermind in New York adults get to participate in show—and—tell, arts—and—crafts such as finger paint, games like musical chairs and even take naps. The month-long course also has class picture day where the adults are expected to have a field trip and a parent day.

    30-year-old Michelle Joni Lapidos, the brain behind the adult preschool, studied childhood education and has always wanted to be a preschool teacher. She's always on the lookout for new ways to get people in touch with the freedom of childhood. A friend encouraged her to start the mastermind course instead.

    According to Candice, her blogger friend, Preschool Mastermind gives adults a chance to relearn and master the things that they failed to understand as children. "I realized all the significances of what we learn in preschool," said founder Michelle Joni, "People come here and get in touch with their inner child. It's magical. We are bringing ourselves back to another place, another time with ourselves when we are more believing in ourselves, more confident and ready to take on the world."

    "One person's here because they want to learn not to be so serious." Michelle said. "Another's here to learn to be more confident." She explained that most of the classes were planned. However, Joni added that while the planned activities were fun, it was often the spontaneous(自发的)moments that attracted students. "It's the things you don't plan for, the sharing between friends and learning from each other."

Wilderness

    "In wilderness(荒野) is the preservation of the world." This is a famous saying from a writer regarded as one of the fathers of environmentalism. The frequency with which it is borrowed mirrors a heated debate on environmental protection: whether to place wilderness at the heart of what is to be preserved. 

    As John Sauven of Greenpeace UK points out, there is a strong appeal in images of the wild, the untouched; more than anything else, they speak of the nature that many people value most dearly. The urge to leave the subject of such images untouched is strong, and the danger exploitation(开发) brings to such landscapes(景观) is real. Some of these wildernesses also perform functions that humans need—the rainforests, for example, store carbon in vast quantities. To Mr.Sauven, these "ecosystem services" far outweigh the gains from exploitation.

    Lee Lane, a visiting fellow at the Hudson Institute, takes the opposing view. He acknowledges that wildernesses do provide useful services, such as water conservation. But that is not, he argues, a reason to avoid all human presence, or indeed commercial and industrial exploitation. There are ever more people on the Earth, and they reasonably and rightfully want to have better lives, rather than merely struggle for survival. While the ways of using resources have improved, there is still a growing need for raw materials, and some wildernesses contain them in abundance. If they can be tapped without reducing the services those wildernesses provide, the argument goes, there is no further reason not to do so. Being untouched is not, in itself, a characteristic worth valuing above all others.

    I look forwards to seeing these views taken further, and to their being challenged by the other participants. One challenge that suggests itself to me is that both cases need to take on the question of spiritual value a little more directly. And there is a practical question as to whether wildernesses can be exploited without harm.

    This is a topic that calls for not only free expression of feelings, but also the guidance of reason. What position wilderness should enjoy in the preservation of the world obviously deserves much more serious thinking.

    It began as a game: High school and college students studying computer technology figured out they could use personal computers to break into telephone company computers and make free, long-distance telephone calls. These young computer talents soon gained the name "hackers".

    Police arrested a few hackers, but many went on to even more complex hacking. One of them was arrested for making illegal telephone calls and later he used a phone to change a police officer's credit records to get back at the officer for arresting him. He also used a computer to change his college records to give himself better grades.

    As hackers gained experience  they began invading computers at banks, airlines and other businesses. In one case a hacker instructed an airline's computer to give him free airplane tickets.

    The U.S. government is worried that hackers may break into its networks of defense computers. The government's secrets are easily attacked because thousands of government computers are connected by telephone lines that hackers can get into.

    In November 1988, a college student entered a U.S. Defense Department computer network called Arpanet. The hacker injected a computer program that made copies of itself throughout Arpanet. Some hackers use viruses to destroy all the data in a computer. But in this case, government officials shut down the network before the program reached every computer in the system. Shutting down the system angered many researchers who were using the computers. The hacker turned himself in to the police and he was charged with a crime.

    The incident put the spotlight on computer hacking in the United States. Many companies have hired experts to protect their computers from hackers, and many computer experts now advise companies on how to protect their computers.

    The U.S. government believes foreign governments have hired hackers to try to break into top-secret defense computers.

    Experts disagree over whether a computer network can ever be safe from hacking. But in the future, some of the most outstanding minds in the U.S. will be working to frustrate the attempts of computer hackers.

Britain appears to be in a mental-health crisis. In the past decade no European country has seen a greater increase in the use of antidepressants(抗抑郁药); now only the Portuguese and Icelanders are popping more of the {#blank#}1{#/blank#}. Around 4.5m Britons were in contact with mental-health services in 2021-22, a rise of almost l m in five years.

There are a few reasons why Britons might be unhappier than their {#blank#}2{#/blank#}. One global poll found that teenagers in Britain were some of the loneliest in the world, with few supportive relationships and a low sense of purpose and meaning: all risk factors for poor mental health. Britain's poorest households are also {#blank#}3{#/blank#} off than their equivalents in France and Germany, for example, which makes them more vulnerable to conditions such as anxiety and depression. And Britain's health system can seem more {#blank#}4{#/blank#} than those in most other rich countries. In England alone, some 3.8 m are waiting for mental-health treatment.

Those factors might explain why more people are {#blank#}5{#/blank#} to medication. Another reason is increased awareness. Campaigns around depression and anxiety have been particularly successful in Britain. That is {#blank#}6{#/blank#} a good thing. A reduction in humiliation (蒙羞) has encouraged more people to seek help. Taking antidepressants – or using mental-health services — has become much more acceptable.

But there is a {#blank#}7{#/blank#} to this, as The Economist recently reported. Surveys suggest that Britons are increasingly {#blank#}8{#/blank#} common human emotions, such as stress and grief, as mental illnesses. "You're going to lose any sense of what mental illness is if you start to {#blank#}9{#/blank#} it to 30%, 50% of the population," says Adrian Massey, author of a book called "Sick-Note Britain".

For all the focus on anxiety and depression in campaigns, severe mental illnesses still receive too little attention. This is a problem: according to the GBD, Britain has the highest rates of severe mental illness in Europe. The causes of such conditions are unclear, but seem to involve a {#blank#}10{#/blank#} interplay of genetic and environmental factors. Illegal drug misuse, for which Britain has among the highest rates in the region, also plays a role.
