One of the most popular and enduring myths about depression is that depressed people are sad all the time—and that by extension, people who are happy can't be experiencing depression, even if they say they are. It is a mistaken version of depression. Depression doesn't make you sad all the time.

    When I'm having a depressive feeling, I'm not walking around in black clothes, and weeping. I go out with friends. I play jokes. I keep working, and have friendly chats with the people I work with. I read books. Above all, I experience moments of happiness. Yet I feel a strange conflicting pressure. On the one hand, I feel like I need to engage in a sort of sadness for people to understand that I really am depressed and that each day is a struggle for me. Because that way I will appear suitably sad, and thus, depressed—and then maybe people will recognize that I'm depressed and perhaps they'll even offer support and assistance.

    On the other hand, I feel an extreme pressure to perform just the opposite, because sad depressed people are boring and no fun, as I am continually reminded every time I speak openly about depression or express feelings of sadness and frustration. I'm caught in a trap where if I don't perform sadness, I'm not really depressed, but if I express sadness at all to any degree, I'm annoying and boring and should stop being so self-centered. Depression can become your master, but you can slip out from under it occasionally. And many depressed people don't actually spend it fainting dramatically on the couch and talking about how miserable they are.

    Your next car might drive itself. After years of trials on city streets, driverless vehicles are now nearing the live phase. Last moth, a driverless bus began carrying passengers through Lyon, France, Most in the automobile industry think self-driving vehicles will be on the road by 2020 or before.

    Driverless cars will at first be huddled with human-driven cars. But the first places where they will become dominant（统治的）are dense urban areas — precisely the spots most damaged by the automobile age. Many advanced cities are already reducing the role of human-driven cargo. Driverless cars will quicken that process and will bring us enormous benefits.

    Driverless cars will reduce accidents by around 90 percent. That's big—the annual death toll on the world's roads is about 1.2 million a year. Pollution and carbon emissions will drop, because urban driverless cars will be electric. The old, otherwise they would stay at home most of the time and the disabled and teenagers will suddenly gain mobility.

    On the other hand, driverless cars will bring catastrophe. The best thing about the automobile age was that it employed tens of millions of people to make, market, insure and drive vehicles. Over the next 20 years, the mostly low-skilled men who now drive trucks, taxis and buses will see their jobs reduced. Carmakers are especially scared. The few cars of the future might be made by tech companies such as Apple, Baidu and Google. Imaging the impact on Germany, where the automotive sector is the largest industry.

    Dramatic change is coming, and driverless cars could arrive by 2020. But governments have barely begun thinking about it. Only 6 percent of the biggest US cities have factored them into their long-term planning.

    A decade ago anyone hardly saw the Smartphone coming. It has bought an epidemic of mass addiction. Let's hope we do a better job of handling the driverless car.

    For the brave in the army, being sent away from home is just part of the duty. However, it's never easy especially for those with children. So, when I found out I was going to stay in South Korea for a year, I was nervous about how my five children, particularly my eldest daughter Abigail, would take the news since it meant I wouldn't be home to see her graduate from high school.

    To my surprise, Abigail told me not to worry and even suggested we make the news known among family members. "We've been lucky you haven't had to be sent abroad yet. Anyway, we can get connected through the Internet. See me on your phone." Abigail said. She stepped into many of my roles when I was gone. I wanted to find a way to thank her and show her how proud I was of her. I started planning the special surprise when my request to return home a few weeks earlier to attend Abigail's graduation ceremony(典礼) was approved.

    When my time in South Korea finally came to an end, I flew home, and stayed in a hotel. On Abigail's graduation day, I hid in an office behind the stage waiting until I heard her name called. I just kept thinking "Don't cry. Don't trip in your heels. Don't fall over." At last! Abigail was up on stage. I slipped up behind her, whispered in her ear, and around she turned! "I was just thinking, like, 'You aren't supposed to be here. What? What? How?' It was the biggest shock... I'm pretty sure my dad made people he didn't even know cry. Emotional for everyone." Abigail cried.

    You know what followed: embraces, kisses, tears, laughs, flowers, wishes...; aren't they what a family have in store?

    The next time your brain refuses to recall a simple fact or name, be thankful. That could be a sign that your brain is getting rid of unnecessary information so that it can operate more efficiently, and help you make better decisions.

The researchers say there are numerous neurobiological(神经生物学的)studies conducted on how the brain stores information, a process called persistence (暂留). However, scientists also assumed that our occasional inability to recall facts was due to a are an the brain. In 2013, scientists discovered that as new neurons combine with the hippocampus(海马区)—a region of the brain that plays a significant role in learning and remembering—they overwrite old memories, making them harder to access. There is also evidence that the brain weakens or removes connections between neurons, in which memories are encoded.

    The scientists have a theory on why the brain spends so much energy erasing memories. They say what the brain decides to forget is determined by our daily life. An example is that our brains remember phone numbers according to the need. Instead of storing this irrelevant information that our phones can store for us, our brains are freed up to store the memories that actually do matter for us. They also believe that memorizing too much detail could prevent us from making good decisions.

    So the next time you are unable to recall a seemingly important fact, don't be hard on yourself. Just throw it to your brain's “rubbish can” to make room for information that can contribute to making you smarter! Remember, even Albert Einstein was absent-minded!

    Florence, Italy

    Who should go: art lovers, Renaissance historians and leather handbag shoppers with high credit limits.

    When to go: spring or fall. Travelers usually avoid summer in Florence.

    Paris, France

    Who should go: starving artists, Henry Miller fans, traditional food lovers.

    When to go: spring is the best time. That's what they all say, anyway. Autumn isn't bad, either, but I'd rather be rooting around the south of France in search of truffles (松露) in autumn. Summer in Paris isn't bad, really.

    Amsterdam, Holland

    Who should go: lovers of Dutch Master (artists I mean, like Rembrandt, not cigars), bicyclists—it's a bike city in a flat land.

    When to go: it can rain at any time in Amsterdam, but that's not a reason for not visiting this fascinating city. Off season tourists will be rewarded with good enough weather to stick around. Summer is good for sun lovers.

    Madrid, Spain

    Who should go: night owls—Madrid never sleeps, art lovers—the Prado is second only to the Louvre in presenting serious art, party-goers.

    When to go: spring, when days are warm and the nights are pleasantly cool. Demand for outside eating and drinking starts becoming stronger in March or April. Street life peaks in June and then slows in July and August as the temperature peaks. Autumn is also good, although you'll risk some rains.

    Venice, Italy

    Who should go: romantic dreamers who like walking through automobile-free streets, your mother (she'll want you to take her there, trust me), almost anyone who wants to see something really different and romantic.

    When to go: February is the time when the famous Venice Carnival is held and the weather is usually cold and foggy—perfect weather for Venice. Summer? A large number of tourists in shorts and whiny children ruin the atmosphere. You'll greatly enjoy yourself there in spring and early fall.
