1 . Independent living at home is the ideal for every aging person. But a fall or other health-threatening incidents can change everything rapidly.

The wearable “panic buttons” introduced in the late 1980s were a great advance. But they only work if people actually wear them and can reach the button in an emergency. Today there are passive wearables that automatically detect falls, and camera-based systems to monitor elder safety.

Coming from a 40-year career in the semiconductor and wireless communication field, Rafi Zack decided to find a better alternative. “People aren’t devoted to wearing small devices 24/7, and camera-based systems are an invasion（侵犯）of privacy,” he points out, “The most challenging aspect is a fall. How fast we can detect a fall matters because the medical situation worsens quickly. Sometimes people stay on the floor for a long time. We have to find out how to solve that problem.”

Zack is a co-founder, CEO and vice president of R&D at EchoCare Technologies which has developed ECHO (Elderly Care Home Observer), a cloud-connected monitor based on radar technology and machine learning.

Because radar sees through walls, one ECHO unit fixed on the ceiling or wall can monitor one person (or two persons, in a future version) in a standard-sized apartment in a senior living facility. The device detects falls, breathing difficulties, drowning in a bathtub and other dangerous events. It gives out warnings to potential health worsening conditions by continuously monitoring and analyzing the person’s location, posture（姿势）, motion and breath. EchoCare tested the device in the United States, Japan, Australia and Israel. ECHO was certified（认证）in 2019 in Japan with the most aging population in the world.

“Bathrooms were the main testing area where about 17,000 deadly accidents happen annually.” said SMK Director and Executive Vice President Tetsuo Hara. “Bathroom makers, home security service providers and nursing homes are highly interested in EchoCare’s solution.” Zack noted, “As more and more elder people live alone as a result of social distancing, there is an increased need to monitor them without the burden of wearables or privacy-invading cameras.”

2 . What is talent? Are you born with it? Or does it seem to develop over time? Before I start, I’d like to say that one thing everyone agrees on is that the most skilled musicians have worked hard to get there.

While it’s true that a few of us had enough “talent” to avoid extra practice to do just as well as those who did, those who worked hard easily beat us. It is, in fact, very likely that if some of us “talented ones” had actually been practicing and improving our skill, we would have achieved a whole different level.

Another aspect of talent seems to be heart and passion (酷爱). The people I see who are the most talented musicians are crazy about music. They eat, breathe, and live music and they make an extraordinary effort to make it part of their lives. As Remus Badea said, desire for the musician-to-be is significant for them to be successful. This desire is easily found in those considered to be talented. When you want and love something so bad, it drives you and your entire character can be shaped around it. Such determined passion seems to produce incredible skill and talent.

The third aspect (方面) of talent is having talent around you. When surrounded by talented musicians, it only seems natural that you start to catch up to their level Take a look at almost any group of musicians in history. The more talented people in the group the more talented the group is as a whole. A great example of this is the relationship between audio producer and artist. The artist turns up to the studio with their song, and as they work through recording it, the audio producer will often suggest various changes to the song to make it better.

3 . During the COVID-19 pandemic, Julia began her second year as a first grade teacher in an online classroom. One September afternoon, she received a call from and Cynthia, who was having technical difficulties with her granddaughter's tools for online learning.

Julia immediately knew something was wrong with Cynthia. The two women had spoken many times before, but Julia had never heard she sounded like this. Her words were so jumbled that Julia could barely understand her. Julia called her headmaster, Charlie, who convinced her that he would call and check on Cynthia himself.

Just like Julia, Charlie could barely understand Cynthia. He suspected she might be having a stroke (中风) — he recognized the signs from when his own father had suffered one. Charlie immediately became concerned that Cynthia's two grandchildren, ages six and eight, were probably home alone with her and scared. Charlie asked his office manager to send an ambulance to the grandmother's home.

The quick response from Julia and Charlie saved Cynthia's life. She arrived at the hospital in time to get treatment before long-term damage occurred. Thanks to an extended stay in the hospital, she has regained most of the movement throughout her body except for one hand and a region of her mouth.

“I'm proud of the people I work with, that they responded so quickly and that it did make a difference to Cynthia,” says Julia. “I am so pleased to be part of such a caring community.” But the school's crisis response is only one piece of the community's extraordinary efforts to help Cynthia and her granddaughters. Another family with young children took in the two girls.

Virtual learning has been a challenge across the country, but it's fair to say that it has helped the community grow closer. Many teachers there gave their personal phone numbers to students and families in case they needed extra help. In this case, the exchange was literally life-altering.

7 . With the social media freely available, I've realized how easy it is to become a jealous cow. The truth is that however much I remind myself of the many wonderful things I have in my life, there are still moments when I look at those around me and feel bitterly upset by their success.

It's a horrible thing to admit! In an ideal world, I'd never want to be jealous of another person's achievements and I'd want to celebrate the successes of my friends. But sometimes it's hard, even when we want to. But I don't want to live my life as a jealous cow, and I assume you don't either.

It's easier to celebrate other people's wins if you celebrate your own. How often do we take the time to enjoy our success rather than instantly move onto the next thing we want to achieve? Last year, I decided to write a book. It was the only professional goal I set for myself and, while it tired me out, I got there. But as soon as it was done, I started planning my next goal-making the book a success. As I saw other people publishing books, I stopped celebrating and instead began to fear that mine wouldn't compete.

When I told a friend how I was feeling, she reminded me how much easier it is to clap for someone else when we also clap for ourselves. So, I took myself out for lunch, ordered a glass of wine and wrote myself a congratulations card. When I saw all those other books being written on my social media, I felt proud of each and every one of us who had battled to the end of the word count.

The other trick for celebrating other people's success is to realize that there is no limit on success. We can make more, which means that while it might seem as if others have everything and we have nothing, the reality is that life turns quickly and our luck could change at any time. If others have achieved those things, we can too. When we celebrate others, we're acknowledging their achievements but also cheering for ourselves as well as for our hopes and dreams and our belief that we can make them happen. And hopefully, when we do, those people will cheer for us too.

9 . A recent study suggests there's nothing soft about pink, as it is revealed that the pinkest flamingos are the toughest. Published in the Journal Ethology, a recent study found that a pink color of feathers was a good indicator of how aggressive a bird was when feeding, as well as a sign of good health or a signal that the bird was ready to breed(繁育）.

For the study, researchers observed the behavior of flamingos in different feeding situations, ranging from small indoor spaces to large outdoor spaces, with or without a pool.

They found that compared to indoor birds competing for food from a bowl, the outdoor-raised flamingos spent twice as much as time searching for food, so they had less time to show aggressive behaviors. Interestingly, their findings also revealed that when the race for food turned hot, the birds most likely to appeal to arms were the pinkest, whether they were male or female.

“The color of flamingos comes from their food, more specifically, from the algae(藻类）that they absorb from water. So the more food they have, the pinker the birds are,” said Dr. Paul Rose, from the University of Exeter, in a statement. “Flamingos live in large groups with complex structures, in which color plays an important role.”

Flamingos don't have a breeding season. Instead, they breed when they are healthy enough to do so. Their health is indicated by the color of the feathers, which is pinker in their prime and paler when they weak. So, the signal that a bird is ready to breed is described as a pink flush in its feathers, which goes away when the bird parents a chick or already passes its best reproductive time.

A healthy pink flamingo will have more time and energy to be aggressive and dominant when feeding. When birds have to crowd together to get their food, they fight more and therefore spend less time feeding, leading to the fading color of flamingos that are already weak. “And this definitely is unfavorable for their reproduction,” Rose said.

The research provides a direction for zoos to feed their flamingos and keep them content and colorful. That is, ensure captive birds are fed in a wide space, as crowded conditions are more likely to result in fights. “Based on my observations, I suggested some changes. And the keepers were willing to try them out. As a result, we've got pinker, more relaxed flamingos," said Dr. Rose.

10 . The joy of giving is real, according to a study. Research presented in the Journal of the Association for Psychological Science shows that those who give gifts are happier — and happier for longer — than those who receive gifts.

Researchers conducted two studies last year. In one，participants were given $5 every day for five days and were required to spend the money on the same thing each day. Some participants were required to spend the money on themselves, while others were required to give to make a donation to charity. In a second experiment that was done online, participants played 10 rounds of a word puzzle game and each won 5 cents per round, which they could keep or donate.

In both experiments, participants reported their overall happiness. Those who donated their money showed that their happiness declined at a much slower rate than those who kept the money or spent it on themselves.

The researchers note that when people focus on an outcome, they can easily compare outcomes, which may diminish their sensitivity to each experience. When people focus on an action, they may focus less on comparison and instead experience each act of giving as a unique happiness-inducing event. Further analyses ruled out some potential alternative explanations, such as the possibility that participants who gave to others had to think longer and harder about what to give, which could promote higher happiness.

The results are especially interesting because according to one of the researchers, Ed O’Brien of the University of Chicago Booth School of Business, they conflict with past research. “If you want to sustain happiness over time, past research tells us that we need to take a break from what were currently consuming and experience something new. Our research reveals that the kind of thing may matter more than assumed: Repeated giving, even in identical ways to identical other，may continue to feel relatively fresh and relatively pleasurable the more we do it,” O’Brien said.

So for all the holiday gifts you give this season, expect to feel happy and know that feeling is going to stick around for a while.
