Sandra Bullock turned 51 last month. But because she looks exactly the same as she did in Miss Congeniality, a movie filmed back in the 20^th century, everyone calls her “ageless.” Bullock is just one of a number of stars in their 40s and 50s who've had birthdays recently but have not gotten older, unlike the rest of us in their age group. Take Halle Berry. One website put a photo of her 20 years ago next to one of the newly 49-year-old Berry and dared us to choose which was which. “This Is What 49 Looks Like,” it said. Seriously, if that's what 49 looks like, I must be 71.

    However, even a generation ago, famous faces evolved. Look at a picture of Grace Kelly at age 52 in the early 1980s. She looks like a beautiful middle-aged woman. Today she'd look old for her age.

    The goal now is to prevent aging while you are still young, using all the magical nonsurgical options medicine has to offer. Eventually these techniques will become less expensive, and ordinary people my daughter's age will have them. Already anti-aging is starting to be considered maintenance, like coloring your hair. My friends and I find ourselves openly debating techniques that we used to make fun of. Does fat-freezing work? How much time do you have to spend in the gym to keep the body of a 35-year-old after 50? It's all so exhausting. But members of the next generation have it tougher. They'll have to ask themselves whether they want to spend their youth trying not to get old. I've already seen “Sexy at 70” headlines. Will everyone be expected to go to their graves(坟墓) looking hot?

    I also have to wonder what else we are slowing along with age. How do you move on if you're working so hard to stay the same? And besides, if you've known the ache of watching a daughter pack up for college, you know you can't stop the clock.

    The Things Successful People Do Differently

    Why have you been so successful in reaching some of your goals, but not others? If you aren't sure, you are far from alone in your confusion. It turns out that even brilliant, highly accomplished people are pretty lousy when it comes to understanding why they succeed or fail. The intuitive(直觉的) answer--that you are born with certain talents and lacking in others--is really just one small piece of the puzzle. In fact, decades of research on achievement suggests that successful people reach their goals not simply because of who they are, but more often because of what they do.

    1）Get specific.

    When you set yourself a goal, try to be as specific as possible. “Lose 5 pounds” is a better goal than “lose some weight,” because it gives you a clear idea of what success looks like. Knowing exactly what you want to achieve keeps you motivated until you get there. Also, think about the specific actions that need to be taken to reach your goal. Just promising you'll “eat less” or “sleep more” is too vague--be clear and precise. “I'll be in bed by 10pm on weeknights” leaves no room for doubt about what you need to do, and whether or not you've actually done it.

    2）Seize the moment to act on your goals.

    To seize the moment, decide in advance when and where you will take each action you want to take. Again, be as specific as possible (e.g., “If it's Monday, Wednesday, or Friday, I'll work out for 30 minutes before work.”) Studies show that this kind of planning will help your brain to detect and seize the opportunity when it arises, increasing your chances of success by roughly 300%.

    3）Know exactly how far you have left to go.

     Achieving any goal also requires honest and regular monitoring of your progress--if not by others, then by you yourself. If you don't know how well you are doing, you can't adjust your behavior or your strategies accordingly. Check your progress frequently--weekly, or even daily, depending on the goal.

    When people reunite with their loved ones，it's usually all extremely happy moment. But what is their most common response to seeing them again? It may seem strange，but most of the time they break down in tears.

    Now a group of psychologists (心理学家) from Yale University say they have found the reason why，and that crying tears of joy may well be the body's way of keeping emotional(情感的) balance. “They seem to take place when people are overtaken by strong positive emotions，and people who do this seem to recover better from those strong emotions，” Oriana Aragon，the lead researcher said.

    Aragon and her fellow psychologists looked at hundreds of participants' emotional responses to different things，including happy reunions and cute babies. Many participants said they would react in a negative or aggressive way to the positive things—to cry at happy moments and want to pinch(捏) a cute baby's face or even tell them “I want to eat you up!” But then researchers found that these people were able to calm down from strong emotions more quickly.

    There are many other examples of times when people respond to a positive experience with a negative emotional reaction. At an exciting concert, fans scream at their idols(偶像). People who have just had a big lottery win are often in floods of tears. “These findings advance our understanding of how people express and control their emotions, which is importantly related to mental and physical health, the quality of relationships with others, and even how well people work together.” said Aragon.

    The European Parliament has approved a law banning a wide-range of single-use plastic items, such as straws and cotton buds by 2021. "Europe is setting new standards, paving the way(铺路) for the rest of the world," the European Commission's vice-president Frans Timmermans, who is responsible for sustainable development, said in a statement.

    The new plans come after the EC found that plastics make up more than 80% of marine litter, which has disastrous effects on wildlife and habitats. The EU parliament notes that because of its slow rate of breaking down, plastic residue(残余) has been found in marine species as well as fish and shellfish - and therefore also makes its way into the human food chain.

    Under the new European law, tobacco companies will be required to cover the costs for the collection of cigarette butts. Manufacturers of fishing tools will also have to pay for the retrieval(找回) of any plastic nets that have been left at sea. There's also a new focus on further raising public awareness, where producers of items such as tobacco filters(滤嘴), plastic cups, and wet wipes will be required to clearly explain to users how to appropriately dispose of them.

    The European Commission first suggested the ban in May, which was approved by member states in October. China last year banned the import of 24 varieties of solid waste, including types of plastic and unsorted paper, putting pressure on Europe to deal with its own waste.

    The World Economic Forum estimates that there are about 150 million tons of plastic in the world's seas. A study published in Science in 2015 suggested that between 5 and 13 million tons more are flowing into them every year. Research shows there will be more plastic than fish by weight in the world's oceans by 2050, which has encouraged policymakers, individuals and companies into action.

    Researchers have found bees can do basic mathematics, in a discovery that deepens our understanding of the relationship between brain size and brain power. Recently, A study conducted by researchers from RMIT University in Melbourne, Australia showed that bees could perform arithmetic operations like addition and subtraction (减法).

    Solving math problems requires a complex level of involving the mental management of numbers, long-term rules and short-term working memory. The finding that even the tiny brain of a honeybee can grasp basic mathematical operations has a possible effect on the future development of Artificial Intelligence, particularly in improving rapid learning.

    RMIT's Professor Adrian Dyer said numerical (数字的) operations like addition and subtraction are complex because they require two levels of processing. “You need to be able to hold the rules around adding and subtracting in your long-term memory, while mentally using skillfully a set of given numbers in your short-term memory,” Dyer said. “On top of this, our bees also used their short-term memories to solve arithmetic problems, as they learned to recognize plus or minus as abstract concepts.”

    The findings suggest that advanced numerical cognition (认知) may be found much more widely in nature among non-human animals than previously suspected.

    “If math doesn't require a massive brain, there might also be new ways for us to include interactions of both long-term rules and working memory in designs to improve rapid AI learning of new problems,” said Dyer.

    Many species can understand the difference between quantities and use this to search for food, make decisions and solve problems. But numerical cognition, such as exact number and arithmetic operations, requires a more complex level of processing.

    Previous studies have shown some primates (灵长目动物), birds, babies and even spiders can add and/or subtract. The new research, published in Science Advances, adds bees to that list.

    Positive thinking is a significant element of happiness. In order to become a positive thinker, determination and consistency are important. The first thing to know about positive thinking is that everyone can do it.  With certain cognitive (认知的) and behavioral changes, we can all become positive thinkers. Another important factor is that being a positive thinker does not mean you become numb to anything that is not working properly in your life or is negative - it just means that you approach life and face challenges with a healthier outlook.

    Instead of selectively attending to negative events, focus on the positive ones. Then pay attention to the delayed consequences of your behavior rather than the immediate ones. For example, if a job is not going like you want, focus on the fact that you have a job and how you can take your time to make the situation better.

    Challenge any internal attributions and see if you compare your behavior to standards that are excessively rigid and perfectionistic. If so, change these and be reasonable with your comparisons. For example, if you constantly compare your weaknesses with other people's strengths, then switch this and compare yourself with those who are doing poorer than you as well. Overall, people who focus more on their strengths than their weaknesses but at the same time are aware of their weaknesses have a healthier self-evaluation result.

    When faced with too much fear about a situation, imagine the worst case and visualize a solution for it, then let go of fear. This way, you will be prepared for anything and your fear will not block you from being open and creative to different solutions. For example, if you are constantly worried about losing your job up to a point where it is creating a lot of anxiety and fear and is effecting your performance and your happiness negatively, then think of losing your job, visualize how you will handle it, find solutions in your mind and then let go of the thought and the fear attached to it.

    So positive thinkers are better problem solvers and have better interactions. In addition to that, people who are positive thinkers are happier and more satisfied with their life.
