According to a survey, only 4% of the people in the world are left-handed. Why? One theory centers on the two halves of the brain. For example, the left half and the right half, each of which functions differently. Medical science believes that the left half of the brain dominates over the right half. The foundation of this theory is the fact that nerves from the brain cross over at neck-level to the opposite side of the body, and nerves from the other side of the brain reciprocate (互换). The end re­sult is that the opposite sides of the body are controlled by the opposite sides of the brain.

    The dominant left half of the brain, which kindly supplies the right half of the body, theoretically makes it more skillful in read­ing, writing, speaking, and working, and makes most people right-handed. Lefties, however, whose right half of the brain dominates, work best with the left side of their bodies.

    Theory number two focuses on the asymmetrical nature of the body. Examples of the asymmetry, which flows from head to toe, are that the right side of our faces differs slightly from the left, that our legs differ in strength, or that our feet vary in size. One aspect of this asymmetry is that for most people the right hand is stronger than the left.

    There is no doubt that all exist in a “right-handed society”, which produces most basics, including scissors, doorknobs, locks, screwdrivers, automobiles, buttons on clothing, and musical instru­ments for the 96%. Left-handed people make up for the unfairness by being members of an elite (精英) society, which includes many of the greatest geniuses, including Michelangelo and Leonardo da Vinci.

    Some of the best research on daily experience is rooted in rates of positive and negative interactions, which has proved that being blindly positive or negative can cause others to be frustrated or annoyed or to simply tune out.

    Over the last two decades, scientists have made remarkable predictions simply by watching people interact with one another and then scoring the conversations based on the rate of positive and negative interactions. Researchers have used the findings to predict everything from the likelihood that a couple will divorce to the chances of a work team with high customer satisfaction and productivity levels.

    More recent research helps explain why these brief exchanges matter so much. When you experience negative emotions as a result of criticism or rejection, for example, your body produces higher levels of the stress hormone, which shuts down much of your thinking and activates (激活) conflict and defense mechanisms (机制). You assume that situations are worse than they actually are.

    When you experience a positive interaction, it activates a very different response. Positive exchanges increase your body's production of oxytocin, a feel-good that increases your ability to communicate with, cooperate with and trust others. But the effects of a positive occurrence are less dramatic and lasting than they are for a negative one.

    We need at least three to five positive interactions to outweigh every one negative exchange. Bad moments simply outweigh good ones. Whether you're having a conversation, keep this simple short cut in mind: At least 80 percent of your conversations should be focused on what's going right.

    Workplaces, for example, often see this. During performance reviews, managers routinely spend 80 percent of their time on weaknesses and “areas for improvement”. They spend roughly 20 percent of the time on strengths and positive aspects. Any time you have discussions with a person or group, spend the vast majority of the time talking about what is working, and use the remaining time to address weaknesses.

    School days are supposed to be the best days of your life and part of that experience usually involves some unforgettable physical activities. I asked some people to give me their memories of what happened to them on the sports field and beyond, and this is what they told me.

    Cup winners

    When I was about ten, the football team from our year unexplainably made it to the cup final of the local schools' league. I say unexplainably because I only remember us losing nearly every match we played. Anyway, in the final I set up the winning goal, a brilliant cross to my mate David who headed the ball in just before the final whistle. I still have a photograph of the team holding the cup.

    Forest hike

    I remember having to lead a group of eight boys on a school expedition for the best part of two days when I was a teenager. Even though we got lost at one point, I managed to keep them all together and get them from one end of a large forest to the other and back by sheer(纯粹的)force of will. I was chosen to be the leader, I think, because I was the only one who knew how to read a map!

    When we arrived back at the campsite, we found out that all the other groups had cheated and hitched(搭便车)most of the way instead… I felt a bit stupid, but also rather proud of myself at the same time for having done it properly.

    Learning to swim, learning to drown

    I learned to swim comparatively late, I suppose. I was maybe nine years old but my brother had a painful experience which nearly put him off for life. We lived in the USA for a while and had access to a university pool where the coaches had trained the American Olympic team. In those days, though, their idea of teaching kids how to swim was to tie a can to their ankles with a bit of string, throw them in the deep end and shout "Swim!". I am surprised my brother survived at all. He could only have been about six at the time.

    Food is necessary for offering energy to our bodies, but sometimes we buy too much of it at the store. When your food starts to go bad, there are many other ways you can still make use of it instead of throwing it away.

    Before throwing away old bananas, you can use the peels (皮) to shine up metals and leathers. Press the peel against the surface, move it backwards and forwards and then polish clean it with an old cloth. Banana meat is also good for reducing wrinkles. Put a bit on those trouble spots, let it sit for a while, and then wash it off, and your wrinkles will go away. Lemons are great for lightening skin and hair. If you have trouble with some skin diseases, like red spots on your face, put a bit of fresh lemon juice on them and leave it overnight. You'll notice a difference in the morning. Apples will help ripen (使成熟) tomatoes quickly when they are placed together in a paper bag, and orange peels are great fire starters for your next backyard campfire party.

    If your dog or cat brings home fleas, using salt is a great way to get rid of them around the house. Just pour salt into the vacuum cleaner (真空吸尘器). Let it sit, then vacuum up the fleas. The salt can kill the fleas. Be sure to throw away the vacuum bag or empty the vacuum bin immediately, or some of the fleas can climb out.

    Beer is a great hair lightener. If you are out of lemons, try dipping your hair in beer before going outside. Just don't forget to wash it out afterwards. Milk is great for removing dirty marks, especially if it is some type of ink.

    As you can see, there are many other uses for everyday foods around the house. So next time, before throwing food away thinking it is of no use, stop for a moment and think about all their uses talked about here.

    It started during a yoga class. She felt a strange pull on her neck, a feeling completely foreign to her. Her friend suggested she rush to the emergency room. It turned out that she was having a heart attack.

    She didn't share similar symptoms with someone who was likely to have a heart attack. She exercised, watched her plate and did not smoke. But on reviewing her medical history, I found that her cholesterol (胆固醇) level was sky-high. She had been prescribed a cholesterol-lowering statin (他汀) medication, but she never picked up the prescription because of the scary things she had read about statins on the Internet. She was the victim of fake medical news.

    While misinformation has been the object of great attention in politics, medical misinformation might lead to an increase in deaths. As is true with fake news in general, medical lies tend to spread further than truths on the Internet—and they have very real bad consequences.

    False medical information can also lead to patients experiencing greater side effects through the "nocebo effect (反安慰剂效应) ". Sometimes patients benefit from an intervention (干预) simply because they believe they will—that's the placebo effect (安慰剂效应). The nocebo effect is the opposite. Patients can experience harmful effects because they anticipate them. This is very true of statins. In blinded trials, patients who get statins are no more likely to report feeling muscle aches than patients who get a placebo. Yet, in clinical practice, according to one study, almost a fifth of patients taking statins report side effects, leading many to discontinue the drugs.

    What else is on the fake news hit list? As always, vaccines (疫苗) . False concerns that the vaccine may cause side effects have greatly reduced coverage rates.

    Cancer is another big target for pushers of medical misinformation—many of whom refuse alternative therapies. "Though most people think cancer tumors are bad, they're actually the way your body attempts to contain the harmful cells," one fake news story reads. It warns that prescription medications lead to the uncontrolled cell mutations (变异) .

    Silicon Valley needs to face this problem. I am not a free-speech lawyer, but when human health is at risk, perhaps search engines, social media platforms and websites should be held responsible for promoting or hosting fake information. Meanwhile, journalists should do a better job of spreading accurate information.
