【推荐2】Popular people are admired and loved by their peers (同龄人).     1     Popular people have plenty of friends and usually have a high social status in their peer group. Here are some general tips that will help you become a more likable and popular person.

Avoid offering help in exchange for approval (认可). Trying to be helpful will have the opposite effect.     2     Popular people help others because they have a useful skill, not because they want to win someone else’s friendship.

Be the glue in your social circle. When you have plans to meet a group of friends for a social outing, make a habit of inviting someone who hasn’t met everyone in the group yet. If you re hanging out with a friend and run into another friend, remember to introduce them to each other.     3    

Practice positivity. People who often complain about life and are more pessimistic have fewer friends. Therefore, it’s important to have a positive attitude and avoid constant complaining.     4     It can be a key step in making close friends. But if you talk about your problems over and over again, your friends might not enjoy hanging out with you.

    5     Many people make the mistake of avoiding social relationships at their school or workplace. They think these places are for work or studying, not socializing. But most of us spend a lot of time at work or college. If you refuse to socialize with people you see almost every day, you’ll miss out on some valuable relationships.

【推荐3】Romantic attachment is one of the best predictors of happiness that social scientists have identified. For example, my review of the General Social Survey finds that although 27 percent of married Americans said they were “very happy” with their lives, only 11 percent of those respondents who were never married, divorced, separated, or widowed answered this way. And research in the Journal of Research in Personality has shown that marriage can protect happiness in adulthood.

These findings may help explain the well-documented decline in American happiness, especially among young adults. The percentage of adults who are currently married has fallen from almost 70 in 1960 to about 50 today. The solution to the happiness deficit (赤字) — for the nation as well as among individuals — is simply to encourage more people to pair off. However, a closer look at the singles trend suggests that the problem is not a lack of available partners, but that young adults may unintentionally be avoiding romantic attachment.

Psychologists commonly measure the health of attachment through two dimensions: anxiety and avoidance the latter meaning a resistance to intimacy (亲密). To score lower on each dimension is better. An insecure bond can involve someone being anxious but not avoidant, avoidant but not anxious, or both, while secure attachment is on the other hand. Unfortunately, insecure attachment is becoming more and more common. Over the past two decades, successive groups of studied college students have shown an increasing likelihood of experiencing one of the insecure styles. One particular insecure style-avoidance-is associated with a greater preference for singlehood. That tells us that the underlying problem is chiefly one of greater avoidance.

The popularity of avoidant attachment is a more reasonable explanation for the increase in unhappiness among young adults than their simply being uncoupled. After all, we also know that singlehood can make some people happier, and that a bad romantic partnership is clearly worse than no relationship at all. But in contrast to that mixed picture, many studies show that avoidant attachment is associated with lower satisfaction with life.

So what is causing this mass romantic avoidance? Two psychologists provided clues in a paper published in 2022 that was based on surveys of university students in Cyprus, including what led them to prefer being single. Strongly predictive of singledom, the researchers found, was not only a preoccupation with work and career but also the wide spread of so-called Dark Triad(narcissism, Machiavellianism, and psychopathy). In other words, people may avoid romantic commitment if they are especially self-centered or work-focused.

【推荐2】What will astronauts wear in more than 50 years? A brand-new spacesuit is developing.

Progress on the suit has been overshadowed(使不快乐). “The EEMU represents the first new spacesuit that NASA has developed in over 40 years, George Nield, previously the associate administrator for commercial space transportation at the Federal Aviation Administration, said. “So far, it looks like things are pretty on schedule.”

Nield outlined the agency’s plan to build five EEMU suits in the initial (最初的)group. One for design tests is almost done and should be completed in December. A second will be built for qualification testing and a third will be tested in orbit on the International Space Station. The final two suits of the set will walk on the moon in 2024 on a mission called Artemis 3.

In addition to the main spacesuits, each astronaut will also require an internal cooling garment (衣服), and NASA has now completed the first prototype of that undergarment, according to Nield. And the agency also needs to upgrade the backpack—like Portable Life Support System that astronauts carry to stay alive.

Meanwhile, NASA got a sense of how the new suit will perform on the moon by testing the design underwater. Underwater, astronauts can get a feel for moving around in a spacesuit and using the tools they will operate during a spacewalk. Lately, NASA has been using the pool to study movements like collecting moon rock and dust, navigating a ladder and planting a flag in the lunar surface.
