2 . My wife and I were at a crowded grocery store not long ago. It was a weekday evening, cold and wet and tense. People were carelessly blocking aisles, complaining and cutting one another off with their carts. At one point, two women quarreled for several minutes in the freezer section.

Things got worse at the checkout line. The cashier scanned a man's discount card, but he misread the savings on her screen as an additional charge. He decided she was acting on purpose and began to argue.

Other customers looked away as the cashier tried to reason with him. She called a manager, who took him to customer service. Shaken, she moved to the next customer in line.

We’ve all witnessed uncomfortable scenes like this in public places. My reaction when I see them is both personal and professional. I am a data analyst and sociologist who studies how and why people interact with one another--or why they choose not to. To me, the grocery scene was another example of how our trust in others has disappeared. But it was also a teachable moment on how we can rebuild our faith — starting with just one person.

Therefore, my wife and I reached the disturbed cashier. I grabbed a bottle of water from a nearby cooler and handed it to her. We learned her name was Beth.

“We felt bad about how that man treated you and wanted to buy this for you.” I said.

Beth’s face lit up, and we talked as she scanned our items. She told us she had been working that evening through severe foot pain and would be having surgery later that week. We wished her well in her recovery, and she thanked us as we left.

That is the balancing act, the moment of countering social and emotional pain with healing, that will add up to restore trust across the United States. You can start that pattern in someone else's life , even in a place as ordinary as the neighborhood grocery store.

3 . Robots that can cook are in growing demand in the United States. The increased demand comes at a time when restaurants are trying to put some distance between their workers and customers during the COVID-19.

In a few weeks, White Castle restaurants will test a robot arm that can cook French fries and other foods. The robot, called Flippy, is a product of Miso Robotics, a company based in Pasadena, California.

Robot food service was becoming popular even before the coronavirus pandemic (冠状病毒). Hospitals, college dining areas and other places tried to meet demand for food while keeping labor costs low. Robot chefs appeared at places like Creator, a restaurant in San Francisco. Now, some say, robots may become necessary for the food service industry. “I expect in the next two years you will see much more robotic adoption (采用) in the food space because of COVID-19,” Jain said.

Some people say, robots can lower the demand for labor. At the University of Arkansas for Medical Sciences in Little Rock, cafe workers used to spend six hours per day making salads, notes Tonya Johnson, the school’s director of nutrition services. But two years ago, the university added a Sally, a kind of robot that now makes around 40 salads per day. By adding Sally, the school was able to cut a job opening in its cooking staff. Johnson said, “I think the pandemic has made us realize how much we need more equipment like Sally.”

Miso Robotics co-founder and chief Buck Jordan said fast food restaurants are already having trouble finding workers, partly as a result of a losing population of young workers. Jordan added that his company’s position is that “automation (自动化) is not a choice”. He added, “You must automate in order to survive in the future.”

5 . Children born in the past four decades had the luxury of being the center of their parents’ attention. The entire family’s resources were poured into their education and well-being.

However，when the same resources are split between two children，the amount distributed to each one is going to shrink.

According to the Hangzhou Daily，when there are two children in the family，parents tend to choose public schools instead of private schools，which are usually more expensive. Each child is enrolled in fewer after-school training classes.

But having a second child may cure some deep-rooted problems in China’s traditional family education.

Having two children in the family can help to prevent one child being spoiled by too much attention，according to People’s Daily. It also spares the only child from the pressure of shouldering parental expectations all alone. Taking care of a sibling also enables children to gain a sense of responsibility，cooperation，obedience and caring.

China’s public education system is also expected to shift. Currently，there are not enough vacancies in kindergarten and schools to accommodate the potential increase in children.

“It’s not only the enrollment capacity of educational institutions that will feel the pressure. People are also placing more emphasis on the quality of education，”Peng Xizhe， director of the Population and Development Research Policy Center at Fudan University，told China Education Daily.

He predicts the government may have to invest more to support the educational system as a result of the new family planning measure.

6 . Coca-Cola, which reportedly produced more than 3 million tons of plastic packaging in 2017, announced Thursday it wants to “help fix the world’s plastic waste problem one community at a time.”

The soda giant is doing so by providing $ 5.4 million for recycling programs in cities like Atlanta, Boston, Denver and Houston. In these cities, partners, like the Green Blue Institute and the Recycling Partnership, which receive the money, will work together to improve recycling rates.

“We focus on areas where we have the ability to make the biggest influence on communities through the funding and expert skills of Coca-Cola employees,” Carlos Pagoagoa, Coca-Cola’s group director of community partnerships, said in a statement. “In each city, local partners will work together to identify barriers to recycling on a local level and test a range of solutions,” he added. “We hope the learnings from these ‘model markets’ can offer solutions to other cities facing similar challenges.”

As part of the effort, the Recycling Partnership and the city of Atlanta, where the cola company’s headquarters are based, will send street teams out to open recycling carts and leave citizens cards informing them what they can and can’t recycle, and let them know how their efforts work.

“Two of the most urgent problems with recycling in the U.S. today are lack of access, followed by pollution in recycling,” Keefe Harrison, CEO of the Recycling Partnership, said in a statement. “We know from the success of Atlanta in 2017 that the citizens want to recycle, and that communicating with them in the street works.”

Last year, Coca-Cola announced its task to collect and reuse a bottle or can for each one it sells, and increase the amount of its products out of recycled materials to 50% by 2030. The brand also aims to make all its packaging fully recyclable by 2025.

7 . How often do you exercise? A new study found that most kids aged 12 to 15 weren't getting enough physical activity. The results were based on about 800 kids. As part of the study, the kids tracked and reported on their own activity levels, and took physical exams.

U. S. fitness guidelines suggest an hour or more of physical activity every day. According to the study, only 1in 4 U.S. kids get enough physical activity.

"It's certainly worrying to see that our kids have such a limited amount of physical activity each day,” said Dr. Stephen Pont. He is an expert on children's health.

Few kids in the study met the guidelines on physical activity that raises the heart rate and makes people breathe harder. Overall, about 25% said they got an hour of that kind of exercise every day. Kids also reported on which activities they did most often outside of school gym class--basketball for boys and running for girls.

The study found that fat teenagers were less active than normal-weight girls and boys. Fat girls were slightly less active than normal-weight girls, but levels were similar among overweight and normal-weight boys. The study also said that the percent of fat children aged 2 to 19 was 17%, or about 12.5 million kids.

"There's always room for improvement," said Tala Fakhouri, who was the leader of the study. She also said the results provide useful information to help with fitness campaigns such as Let's Move, which was initiated by Michelle Obama in 2010. To inspire kids to eat right and get in shape, Michelle visits schools and holds exercise events. She also calls on schools to offer regular gym classes.

The study also found kids who get physical education at school may get better grades.
