My mom takes pride in the fact that I was talking in three and four word sentences before I was ten months old. Some say it's a gift while others simply think I talk too much.

    As my thirties came to a close, I found myself reflecting on my life. I'm very happy and have no significant regrets. However, when I looked back on those times of difficulty, I saw a clear common denominator(特征); I didn't seem to know when to stop talking. Whether it was hurting someone's feelings, or having carelessly told a secret, the incident could have been avoided had I closed my mouth sooner. So I decided to practice the power of quiet.

    To take this step, I needed to understand how people could sit comfortably in a group and not talk. Why does my husband feel completely content to say nothing in a conversation? He's highly intelligent and has wonderful opinions but he'll sit quietly and just listen. Even when he's asked a pointed question, he'll answer with few words while still communicating effectively. What a talent!

    Can you imagine being happy just listening? In surveying those I know who talk less than I do, I got two answers—they either didn't feel confident enough to speak up, or they just didn't feel the need to participate in the conversation. Of course there were other reasons for not talking, but these were the two most popular answers.

    The first one didn't work for me. I'm just fine letting people know what I think about them, and hopefully it will make the conversation much more interesting. The second one didn't work either. I do feel the need to participate. I feel it physically like an electrical pulse through my body; sometimes it's so strong that it causes me to behave badly in the form of interrupting or speaking in an unusually loud voice. I had to look further.

    An interesting thing happened on this journey to the power of quiet. During my weekly yoga class, it came to me like an answer so clear that the words rang in my head like soft, heavenly bells.

    I talked too much so people would know I cared about them. It was my way of taking care of those I love. I decided before my fortieth birthday, that from that day forward, those around me would know I loved them, and cared what they thought and felt, but I was going to practice the power of quiet.

    As my forty-second birthday approaches, I can say that deciding to talk less has been more about focusing on quality rather than quantity. I've found that listening more shows those who I care about that I really do care how they feel. Now when I break in, it means more to them. Oh, sure, I still have my short periods of talking too much, but for the most part this has been one resolution that I can call a success.

    Two new studies suggest that modem running shoes could increase the risk of injuries to runners.

    One study involved sixty-eight healthy young women and men who ran at least twenty-four kilometers a week. The runners were observed on a treadmill machine (跑步机). Sometimes they wore running shoes. Other times they ran barefoot.

    Researchers from the JKM Technologies Company in Virginia, the University of Virginia and the University of Colorado did the study.

They found that running shoes create more stress that could damage knees, hips and ankle joints than running barefoot. They observed that the effect was even greater than the effect reported earlier for walking in high heels.

    The study appeared in the official scientific journal of the American Academy of Physical Medicine.

    The other study appeared in the journal Nature. It compared runners in the United States and Kenya. The researchers were from Harvard University in Massachusetts, Moi University in Kenya and the University of Glasgow in Scotland.

    They divided the runners into three groups. One group had always run shoeless. Another group had always run with shoes. And the third group had changed to shoeless running.

    Runners who wear shoes usually come down heel first. That puts great force on the back of the foot. But the study found that barefoot runners generally land on the front or middle of their foot. That way they ease into their landing and avoid striking their heel.

    Harvard's Daniel Lieberman led the study. He says the way most running shoes are designed may explain why those who wear them land on their heels. The heel of the shoe is bigger and heavier than other parts of the shoe, so it would seem more likely to come down first. Also, the heel generally has thick material under it to soften landings.

    But the researchers do not suggest that runners immediately start running barefoot. They say it takes some training. And there can be risks, like running when your feet are too cold to feel if you get injured.

    The study was partly supported by Vibram, which makes a kind of footwear that it says is like running barefoot. The findings have gotten a lot of attention. But the researchers say there are many problems in the way the press has reported in their paper. So they have tried to explain their findings on a Harvard Website.

    For many, music is as important to the human experience as eating and breathing. We hear music everywhere—at home, the gym, parties and stores. But what kind of music do we prefer to listen to, and when and why do our musical preferences change?

    The relationship between the change of seasons and musical preferences was the focus of a study led by psychologist Terry Pettijohn. He and his team based their research on a previous study that examined the relationship between popular music preferences and the Environmental Security Hypothesis(假设). The results showed that over time, when social and financial conditions were more risky, the songs of the year that were slower, longer, more comforting and serious were most popular. And during periods in which social and financial conditions were generally stable, the result was opposite.

    Building on these findings, Pettijohn and his team wondered if the Hypothesis could also be applied to the change of seasons. For college students, the participants in this study, autumn begins at the start of the school year. Gone are the carefree days of summer, when school is out. Winter means colder temperatures, shorter days, and, in many places in the country, snow. Spring, however, is a different story. It represents a fresh start and when clocks spring forward, we gain an extra hour of daylight. As students walk into summer, they're absorbed in the sunshine and social activities—and enjoy a break from school.

    But do changing seasonal conditions influence musical preferences? To answer this question, the researchers designed two studies. What did they find? Both groups of college students favored more serious music during the seasons of fall and winter, and more active and energetic music during the spring and summer seasons. And these findings, Pettijohn argues, have practical significances.

Devin Jackson, who went from selling tickets to tourists on Times Square to working as an engineer for a number of major corporations, told ABC News that he was 1 that there weren't many Black engineers or coders in the industry. So he decided to do something about it and 2 . 

In 2017, Jackson co-founded the non-profit organization We Build Black which 3 meetups, training courses and workshops for up-and-4 Black engineers. 

In the six years since it 5 , Jackson said his organization has raised millions of dollars, and trained and helped over 3,000 members with their 6 . 

"I became a software engineer and realized that I need to share the 7 with everybody around me and, you know, show my community 8 those freedoms," Jackson said. 

Sheree Edmund, a software engineer, told ABC News that the program allowed her the 9 to grow and have a space to pursue computer programing. Edmund, who was 10 with high functioning autism (孤独症) three years ago, said "It was a community, and an atmosphere where I didn't feel like I had to 11 who I was to fit in. And that made it a lot less 12 to be my real self. "

Jackson encouraged others to 13 their interest in tech and engineering skills, no matter how hard it may seem to 14 the industry. 

"You got to control what you can control at the end of the day and what you control is 15 ," he said. "So get to the grind (磨炼). That's really what I want you to take from this at the end of the day. "
