Complaining happens a lot, probably much more than we even realize. Complaining is easy to do, but it’s not good for us. Doctors have found that people who complain about their health can actually worsen the symptoms of their disease. 【小题1】People who complain frequently can end up losing friends because of their complaints.

If complaining is so harmful, why do we complain? Many people complain to get attention. 【小题2】 Sometimes we complain as a way of connecting with others, starting a conversation. We can complain to make ourselves look better by comparison. There are lots of excuses for complaining.

【小题3】It’s harder to find the positive or just stay quiet. Maya Angelou once said, “If you don’t like something, change it; if you can’t change it, change your attitude. Don’t complain.”

You can have gratitude (感激) or take action to find solutions rather than just complain about problems. 【小题4】It can lead to a new vision. Robert Kennedy once said, “There are those that look at things the way they are, and ask why? I dream of things that never were, and ask why not?”

But how can you stop yourself from complaining? It requires a plan. You could start by not complaining about anything for a week. It won’t be easy but it can be done. When we stop complaining about what’s missing in our lives and start being thankful for all we have, life changes for the better. 【小题5】

One recent night， while I was leafing through its pages of an old journal， my eyes met a quote by the British writer Graham Greene that I had marked， “A prejudice had something in common with an ideal.”In other words， ideals—general descriptions of people's expectations of themselves and others—can often lead us to unreasonable ideas.It got me thinking about how we often allow ourselves to generalize about groups of people.We like to stereotype people by the color of their skin， the year of their birth or any other related factors.

I grew up in a multi-racial corner of America.The different groups were often subject to narrow stereotypes：Jewish people were“greedy”， Mexicans were“poorly educated”， and Asians were“good at math”.These labels were taught to us from a young age.They wormed their way into our belief systems， harming how we came to see others.It made me sad growing up to see people repeat these stereotypes as if they were true.The rush-to judgment of people breeds a culture of discrimination.

You can also see these over-generalized descriptions being made against today's Chinese people.Whether it be a lack of interest or worry among mile millennial being described as “monkish”， or“dad-fashion”which has given the“greasy middle-aged men”tag.stereotypes always seem to gain a foothold in the consciousness of our society.But these generalizations do real harm as these myths may become part of the wider population.

It's about time that we， as a society， walked away from generalizations and stereotypes.I leave you with the words of Martin Luther King Jr.from his famous“I Have a Dream”speech：“T look to a day when people will not be judged by the color of their skin， but by the content of their character.”By reserving judgment and really getting to know the individual you might just find your irrational ideas have no foundation.

Why the youth sense anger in faces

We tend to believe that older people are more positive and younger people are more sensitive to social cues (暗示).

Recently scientists investigated this idea by testing 10,000 men and women. They wanted to see if age affected a person's ability to identify facial emotions, such as fear and anger.

The researchers from McLean Hospital in the US used a Web-based platform to collect happiness data. It showed the participants two headshots (头部特写)of random people. They were then asked to identify which subject was angrier, happier, or more fearful.

The research found that younger people were able to better identify angry and fearful facial cues than older people.

"From studies and anecdotal evidence, we know that the everyday experiences of an adolescent are different from an older person, but we wanted to understand how these experiences might be linked with differences in basic emotion understanding,wrote Laura Germine, the study's senior author.

But what is it that makes young people more sensitive?

"This is the exact age when young people are most sensitive to forms of negative social cues, such as bullying,” Lauren Rutter, the study's lead author, told Science Daily. "The normal development of anger sensitivity can contribute to some of the challenges that arise during this phase of development.

On the contrary, across the whole 10,000-person survey, researchers found no decline in the perception (感知)of happiness among older participants.

“What's remarkable is that we see declines in many visual perceptual abilities as we get older, but here we did not see such declines in the perception of happiness,Germine told Neuro Science News.

She added that these findings fit well with other researches, showing that older adults tend to have more positive emotions and a positive outlook.

Following the paper's release, Rutter told Neuro Science News that gathering their primary research online allowed the team to research into a "much larger and more diverse sample set” than previous studies.
