The baby is just one day old and has not yet left hospital. She is quiet but alert (警觉的). Twenty centimeters from her face researchers have placed a white card with two black spots on it. She stares at it carefully. A researcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, her gaze(凝视) starts to lose its focus—until a third, with three black spots, is presented. Her gaze returns: she looks at it for twice as long as she did at the previous card. Can she tell that the number two is different from three, just 24 hours after coming into the world?

    Or do newborns simply prefer more to fewer? The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes. Perhaps it is just the newness? When slightly older babies were shown cards with pictures of objects (a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again. Babies paid more attention to squares moving randomly(随意地)on a screen when their number changed from two to three, or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two; likewise(同样地) when the researchers started with drumbeats and moved to spots.

    It's a warm summer afternoon. You're cooking up the catch of the day over a campfire. Suddenly, a few raindrops fall on your arms, and before you know it, the sky is opened up. Then you hear what sounds like thunder in the distance. What should you do? Your tent is close by and would offer shelter from the pouring rain. There's a campsite picnic shelter a few minutes down the path. And then you remember that your car is parked down the road. What's your safest choice to make sure you and your families are safe?

    It's a common question for many hikers(徒步者) and campers, especially when they are camping during summer months. Heading to your car is almost always the safest choice. Your tent and a picnic shelter will keep you dry, but they offer little or no protection against lightening. Your car, on the other hand, will keep you dry and protect you from lightening strikes. Protecting yourself against possible lightening strikes is very important; lightening kills an average of 62 people in the US each year. If you keep all of the windows and doors closed in your car, you'll be able to return to your campsite safely.

    Of course, if you're backpacking(背包旅行), not car camping, and you're deep in the woods, your car won't be a good choice. So, what should you do if your car is far away and there's no other safe shelter nearby? First, you'll have to make sure that tree limbs or other objects don't fall on you or your campsite. Then you'll have to get in a safe position to avoid lightening, or flash flood conditions. What else should you do?

    A study, conducted by David Evans of the World Bank and Anna Popova of Stanford University, looked at 19 programs around the world in which individuals were given cash transfers from the government, either as a handout or as a "reward" for something like getting kids to school on time or taking them to the doctor for checkups.

    Evans and Popova looked at the impact those cash transfers had on the family budget and whether or not they led to an increase in spending on alcohol and cigarettes .What they found was that they almost always led to a reduction in a family's alcohol and tobacco purchases.

     The news may surprise some people, but it's true, and the researchers have several theories about why.

    One theory is that the cash transfer made things possible that once seemed impossible. Investing in their kids' education or buying healthier and more expensive foods may be within reach now, but without the cash handout, these goals weren't even a possibility. So families cut back on other expenses (like alcohol and tobacco) to make those dreams a reality.

    Another theory is that people just generally seem to do what they're told. If they are given money and told to use it for their family's welfare, in most cases, they will do just that. And that leads to the third theory: These cash transfers are usually given to women, and studies show that when women control the purse strings, more money is spent on taking care of their children.

    Whatever the reason for the trend, the data is clear—families that receive cash handouts don't waste the money on booze and cigarettes as was previously thought. Instead, they typically use that money for the benefit of their families. And that's money well spent.

    Do you often feel that you aren't taking in as much of the joy around you as you could? I recently caught myself feeling this way, and based on a suggestion by John Horton, coauthor (合著者) of The Inner Game of Stress, I put myself on a 30-day life-appreciation course.

    The only assignment each day was to go outside and appreciate life.

    So I started by taking in the beauty around me. During the first few days, I was able to appreciate my surroundings, although it was an intellectual appreciation, not an emotional one.

    After the first week, it was more uncomfortable to lie in bed and think about things than it was to get up and see them for myself.

    If you often wake up feeling anxious or depressed, or if you don't look forward to each day, then you need to try this course for yourself.

    It's an inner workout that you can do anywhere. It may not change your life, but it will adjust your attitude, and that's pretty helpful in this crazy world.

    I have always believed in ending the day on a positive note by writing a word or two in a gratitude journal and saying something sweet to my wife about the day we shared.

    Now, I have a new morning habit. It hasn't changed my routine one bit, but it has changed the way I look at the world.

    Creating a new habit isn't about perfection – it's about getting what you want by creating a change in your behavior and thinking.

    So now, while I'm making my coffee in the morning, I'm also appreciating what I have.

    It's quick, fulfilling, and a much better way to start my day than looking at my phone or computer.

    And because of this, my attitude is better, as I've already begun my morning on a positive note rather than a problematic one.

    The idea here is that if you can appreciate your life, it actually changes the way you feel about it.

    Appreciation will give you more energy to live the way you would like to live.

    As a means of improving our mood, it's highly underrated (被低估的). The easy task of appreciating what we have simply makes life better.

    A survey said the average Asian dad spent one minute a day with his children. I was shocked. I mean, a whole minute? Every day? Get real. Once a week maybe. The fact is, many Asian males are terrible at kid-related things. In fact, I am one of them.

    Child-rearing (养育) doesn't come naturally to guys. My mother knew the names of our teachers, best friends and crushes. My dad was only vaguely aware there were short people sharing the apartment. My mother bought healthy fresh food at the market every day. My dad would only go shopping when there was nothing in the fridge except a jar of butter. Then he'd buy beer. My mother always knew the right questions to ask our teachers. My dad would ask my English teacher if she could get us a discount on school fees. My mother served kid food to kids. My dad added chili sauce to everything, including our baby food.

    The truth is, mothers have superpowers. My son fell off a wall once and hurt himself all over. I demanded someone bring me a computer so I could google what to do. My wife ignored me and did some sort of chanting (咏诵) phrase such as" Mummy kiss it better," and cured 17 separate injuries in less than 15 seconds.

    Yes, mothers are incredible people, but they are not always correct. Yet honesty forces me to record the fact that mothers only know best 99.99 percent of the time. Here are some famous slip-ups.

    The mother of Bill Gates:" If you're going to drop out of college and hang out with your stupid friends, don't come running to me when you find yourself penniless." The mother of Albert Einstein:" When you grow up, you'll find that sitting around thinking about the nature of time and space won't pay the grocery bills." The mother of George W. Bush: "You'll never be like your dad, who became President of the United States and started his own war."

    If a family member blames you for something you have done, it is important to be careful about how you defend yourself. It is not a good idea to use ways that cause hurt, even if they would help you make a valid point. If you can think of an instance where the other person has done exactly what they accuse you of, for example, it would not be good manners to throw it in their face. You should only bring it up if you don't have a choice. Then, you should make sure that you do it respectfully.

    Even if a family member intentionally goes against reasonable wishes you may have, you should understand that people see even the most fundamental things in very different ways. Remember that people are different. If you consider any noise after midnight to be intolerable, for example, others may see it is completely acceptable. It can take them a great deal of time to change their behavior for a demand that they do not understand.

    Think about the family conflicts that you are worried about now. Check to see if your parents had similar problems. People who grow up with parents who fight unfairly often repeat the same behavior. Consider changing the unfair habits that you grew up with.

    Understand that memories tend to change. In long-standing family disputes, all parties involved tend to have completely different recollections of the original problem.

    Families are a curious concept—while family members often feel nothing but annoyed for one another, they will also often be there for them if they should ever be in serious trouble. When you feel resentment for someone, think about how far you would go for them if they happened to be in trouble. It could help soften you. Think about how you care for the other person.
