When I was 8 years old, I decided to run away from home after a quarrel with my mother. With my suitcase packed and some sandwiches in a bag, I started for the front door.

     My mom asked where I was going. “I'm leaving home,” I said.

     “What's that you're carrying?” she asked.

     “Some clothes and food,” I replied.

     “If you want to run away, that's all right,” she said. “But you came into this home without anything and you can leave the same way.”

     I threw my suitcase and sandwiches on the floor and started for the door again.

     “Wait a minute,” Mom said. “You didn't have any clothes on when you arrived, and I want them back.”

 This infuriated me. I tore my clothes off — shoes, socks, underwear and all — and shouted, “Can I go now?”

     “Yes,” my mom answered, “but once you close that door, don't expect to come back.”

     I was so angry that I shut the door forcefully and stepped out of my home. Then I noticed down the street two neighbor girls walking toward our house. I was so shy that I saw the big spruce (云杉) tree in our yard and jumped under the low-hanging branches. A pile of dried-up brown needles were beneath the tree, and you can't imagine the pain those sharp needles caused to my body.

     After I was sure the girls had passed by, I ran to the front door and knocked at it loudly.

     “It's Billy! Let me in!”

     The voice behind the door answered, “Billy doesn't live here anymore. He ran away from home.”

     Looking behind me to see if anyone else was coming down the street, I said, “Mom! I'm sorry. I'm still your son. Let me in!”

     The door opened and Mom's smiling face appeared. “Did you change your mind about running away?” she asked.

     “What's for supper?” I smiled back.

    Ever walked to the shops only to find, once there, you've completely forgotten what you went for? Or struggled to remember the name of an old friend? For years we've accepted that a forgetful brain is as much a part of ageing as wrinkles and grey hair. But now a new book suggests that we've got it all wrong.

    According to The Secret Life of the Grown-up Brain, by science writer Barbara Strauch, when it comes to the important things, our brains actually get better with age. In fact, she argues that some studies have found that our brain hits its peak between our 40s and 60s— much later than previously thought.

    Furthermore, rather than losing many brain cells as we age, we retain （保留）them, and even produce new ones well into middle age. For years it's been assumed that brain, much like the body, declines with age. But the longest, largest study into what happens to people as they age suggests otherwise.

    This continuing research has followed 6,000 people since 1956, testing them every seven years. It has found that on average, participants performed better on cognitive （认知的）tests in their 40s and 50s than they had done in their 20s. Specifically, older people did better on tests of vocabulary, verbal memory (how many words you can remember) and problem solving.

    Where they performed less well was number ability and perceptual speed－how fast you can push a button when ordered. However, with more complex tasks such as problem-solving and language, we are at our best at middle age and beyond. In short, researchers are now coming up with scientific proof that we do get wiser with age.

    Neuroscientists are also finding that we are happier with ageing. A recent US study found older people were much better at controlling and balancing their emotions. It is thought that when we're younger we need to focus more on the negative aspects of life in order to learn about the possible dangers in the world, but as we get older we've learned our lessons and are sub-consciously aware that we have less time left in life: therefore, it becomes more important for us to be happy.

    Why Black Friday Shoppers Still Crowd Stores

    To many of us, the ideas of rushing out to a superstore the day after Thanksgiving is appealing. Why would anyone race to crowded stores when they could stay in with family, or watch college football? We can't say we know the answer for sure. But we do feel amazed at those who pour into stores looking for Black Friday bargains. Seemingly, nothing can stop them. Not the weather. Not the crowds. And not the fact that hurrying to a store in the age of instant e-commerce seems so…last century.

    To be sure, holiday shopping habits do appear to be shifting. The National Retail (零售) Federation has stopped breaking up its holiday sales numbers by whether they come from e-tail purchases or from physical stores. It's a pretty good sign that retailers don't want to bring further attention to the declining fortunes of brick-and-mortar stores.

    But there is no denying that people still love going to stores. Actual shopping in actual places remains an important part of the holiday ceremony for millions of Americans. To many, it's the difference between playing a sport and playing a video game. As commercial as stores may be, they are still places where actual human beings interact. In a store, the “courageous” shopper performs the approving act of finding a present. That item might be heavily promoted by the store, but it doesn't drop into one's cart. It is picked up and examined before a decision is made. Maybe it gets put back on the shelf when the shopper changes his or her mind. Maybe there is a conversation with a sales clerk. The process is not that different than it would have been decades ago.

    Online, the shopper has barely logged in before being faced with disturbing algorithmic (大数据的) suggestions based on earlier purchases. This hardly qualifies as shopping. This hardly qualifies as thinking.

    Perhaps we are reading too much into the Black Friday phenomenon. But we suspect one reason Black Friday remains is that it involves an act of resistance against the Internet age. That would hardly be unreasonable. There aren't many studies showing that time spent in stores is bad for one's health, while there are quite a few drawing a link between time spent online and depression. Perhaps the people crowding into stores aren't the crazy ones after all.

    Like a lot of health-care professionals, Dr. Brian Goldman finds it extremely difficult to draw boundaries between his work and personal lives. "There's this view that you should suck it up and do one more thing," says the ER physician and host of CBC's White Coat, Black Art. But that "one more thing" often comes at Goldman's expense.

    "You're exhausted and a patient or their family look at you with begging eyes," he says. "So you have this dilemma: say that your shift is over or give until you're totally spent?" Goldman's work stress combined with family tension after his mother was diagnosed with dementia 20 years ago. Caring for her over a decade was difficult, as was dealing with his father's grief. "When someone else is drowning you, you have to grab a life preserver and save yourself," says Goldman.

    Setting boundaries isn't just important for busy professionals; everyone can benefit from managing situations that cause undue stress or pain. Here are some tips.

First, "If someone's behavior makes you unhappy — and it could be anything from the way they speak to you to repeatedly failing to stick to their promise — then there's room to set limits," says Patrick Keelan, a Calgary psychologist. We often avoid setting limits because we prioritize the happiness and comfort of others over ours. In order to control this impulse, Goldman suggests framing the development of boundaries as a form of self-kindness. When facing an overwhelming situation like the one he was in with his father, Goldman suggests reflecting on what is making you feel uncomfortable, unhappy or unappreciated. "You can't relate to others or be kind to others if you aren't kind to yourself," he says.

Second, once you've become aware of your needs, setting and maintaining boundaries requires clear verbal communication. There are three obstacles to enforcing boundaries in a relationship: fear, guilt and self-doubt, says psychologist Nicole MaCance. We often fear that if we set limits, the other person will reject us, or we feel bad claiming our needs. Keelan proposes setting ground rules before relationships become tense. Start by cooperatively listing values — like mutual respect, support, and loyalty — and then building the guidelines from these values. If you're struggling to reach a consensus, Keelan recommends engaging a third party, such as a therapist, to help.

    Now, if you want a boundary to stick to, you can't enable someone in breaking it. As such, it's crucial to establish consequences for  transgressions (越轨). Otherwise, McMance says," you're giving them permission to violate that boundary." If they won't respect your boundaries, you have to do some soul- searching about the value of the relationship. "When you feel bad more than you feel good in this person's presence, and when the relationship is impacting your self-worth and happiness, it's time to reassess," says McCance. Saying no is hard, but she suggests framing it as saying yes to healthier relationships. "We're all better mothers and partners and brothers when we have boundaries."

    Some spiders hunt on the ground, others build webs to trap their food, but the grass water spider catches its prey by running along the surface of the water.

    This special water spider lives on the grassy banks of streams where mosquitoes, damsel flies and other insects come to feed and breed.

    Although it is one of the largest spiders in New Zealand, it has an unusual ability. It doesn't disturb the water as it waits for its meal, and there is barely a ripple(波纹) when it skims(掠过) across the surface at lightning speed to catch its prey.

    Grass water spiders deal swiftly with larger insects like damsel flies by pulling their heads under the water and holding them there until they drown.

    After a meal, the grass water spider spends up to half an hour grooming(修饰) itself. It wipes its eight eyes, brushes its antennae(触角), and takes special care to clean the hairs on its body.

    It is the hairs that trap tiny bubbles(泡沫) of air so that the spider can run down a blade(叶片) of grass and stay underwater for up to an hour when it is frightened. The hairs also keep the spider dry, even underwater.

    It is only when the female spider is caring for the young that she does not hunt on the water. After mating, she produces a large egg sac(囊), which she carries around for five weeks. Once the eggs start to hatch, she attaches the sac to some blades of grass or a thistle. She then tears the sac open and releases the tiny spiders into the nursery web.

This year, the Music Educator Award, presented by the Recording Academy and Grammy Museum, went to Annie Ray, the performing arts department chair and orchestra director at Annandale High School in Fairfax County, Virginia. She attended the awards ceremony in Los Angeles and brought home both a $10,000 prize and matching grant （资助） for her school's music program.

Ray created the Crescendo Orchestra for students with severe intellectual and developmental disabilities, as well as a parent orchestra that teaches nearly 200 caregivers a year to play the same instrument as their children. She got the idea mostly from the Annandale community, which she says represents over 60 countries, including many refugees and immigrants. "There're many cultures that might typically clash, but they come together in this very beautiful harmony," Ray explained. "And that's really uniquely expressed in the orchestra classroom, where we're just all music-ing together."

Ray says the Crescendo Orchestra is focused on teaching students how to play an instrument, through one-on-one instruction tailored to their needs. The orchestra is about much more than just making music, however. "I really push my students to be brave and go outside of their comfort zone. We have to learn how to work together with others," she says.

Ray, who comes from a family of musicians and has played the harp （竖琴） since the age of five, knows firsthand the impact that a great teacher can make on their students. "Why I am where I am is because a teacher changed my life and made me want to be a music educator," she says.

Ray says her warm reception on the awards ceremony is especially meaningful because not many people understand what exactly music educators do in the classroom or how much their work matters. She says that lack of understanding is one of the biggest challenges facing the profession in general. Moreover, she says her school desperately needs new instruments, and adds that she'll use some of her grant money to buy more.
