Many kids don't drink enough water daily, according to a new study. The study's lead author, Erica Kenney, at first planned to look into the amount of sugary drinks kids were drinking in schools. However, during her research she found that many kids were simply not drinking enough water.

    Kenney and her team examined data from a group of 4,000 children, aged 6 to19. The data was taken from the National Health and Nutrition Survey, a study on the health of children in the United States done each year by the Center for Disease Control and Prevention.

    While looking through the survey results, she noticed that more than half of the kids who took part in the study were dehydrated (脱水的). Of that group, boys were 76% more likely than girls not to have enough water in their system. Nearly one quarter of the kids in the survey reported drinking no plain water at all.

    “These findings highlight (突出) a possible health issue that wasn't given a lot of attention in the past,” Kenney said in a statement. “Even though for most of these kids this is not an immediate and great health risk, this is an issue that could really be reducing quality of life and well-being for many children and youth.”

    The United States-National Agriculture Library says average kids need between 10 to 14 cups of water every day. This water can come from a mix of drinks and foods that contain high amounts of water, such as celery, melons or tomatoes. It is also suggested that fluids (液体) come from water instead of sugary drinks that are high in calories and can lead to weight problems.

    Making friends is a skill like many other skills. It improves with practice. If you want to meet people and make friends，you must be willing to take some actions. You must first go where there are people. You won't make friends staying home alone. Join a club or a group. Talking with those who like the same things as you do is much easier. Or join someone in some activities. Many people are nervous when talking to new people. After all meeting strangers means facing the unknown. And it's human nature to feel a bit uncomfortable about the unknown. Most of our fears about dealing with new people come from doubts about ourselves. We imagine other people are judging us or finding us too tall or too short，too this or too that. But don't forget that they must be feeling the same way. Try to accept yourself as you are and try to put the other person at ease. You'll both feel more comfortable.

    Try to act self­confidently even if you don't feel that way. When you enter a room full of strangers，such as a new classroom，walk tall and straight，look directly at other people and smile.

    If you see someone you'd like to speak to，say something. Don't wait for the other person to start a conversation.

    Just meeting someone new does not mean that you will make friends with that  person—friendship is based on mutual liking and“give and take”. It takes time and effort to develop.

    Environmental experts warn that our planet is drowning inplastic.

    The world's cities produce 2 billion tons of trash everyyear. By the year 2050 that number is expected to rise to 3 billion tons. TheWorld Bank estimates that the largest amount of trash today, about 44 percent,is plastic. But we often have to buy packaged goods. And often that packagingis made of plastic.

    Now, that may be changing. A new environmentally-friendlyshopping model was recently launched at the World Economic Forum in Davos,Switzerland. This shopping model, called Loop, aims to replace throwawaycontainers with reusable ones.

    Loop is the idea of Terra Cycle, an American-based recyclingcompany. Its chief, Tom Szaky told the Associated Press (AP) that "removingplastics from the ocean is not enough." He said the point is to get awayfrom single-use packages. Szaky said that Loop is the future of shopping. Butit comes from an idea of the past.

    He compared it to the "milkman model" of the 1950sin the United States. Back then, someone brought milk to your doorstep in glassbottles and then left with empty bottles. These could be cleaned and used again.The result is zero-waste.

    Jennifer Morgan from the environmental non-profitorganization Greenpeace also joined in the discussion about Loop at Davos. Shesaid that "Greenpeace welcomes the aim of the Loop Alliance to move awayfrom throwaway culture and disposability." But Morgan questioned whethercompanies worldwide are ready to change their business models.

    Loop is set to launch later this year in three eastern U.S.states, and also in Paris, France and some of the surrounding area. Then Loopplans to expand to the U.S. West Coast, Toronto, Canada and Britain by the endof this year or 2020.

    Regardless of how far we'd like to believe gender (性别) equality in the workplace has come, there's still a yawning gap between male and female leaders in the professional world. A 2018 statistic showed that women nowadays hold just 5.8 percent of CEOS positions at S&P 500 companies, according to Catalyst.

    While it's not a huge shock that women are somewhat underrepresented in leadership positions, what is surprising though, is the fact that females may actually be better suited to lead in almost every area, at least according to new findings from the BI Norwegian Business School.

    In their research, Professor Oyvind L. Martinsen and Professor Lars Glas surveyed 2,900 managers with a special focus on personality types. The results were clear: Women scored higher than men in four of the five major leadership-centric categories while some people believe that men inherently make better leaders—probably because they picture a leader with a commanding voice, which is more typical of men than women—this is piece of research suggests that women are better at methodical management and goal-setting, openness, sociability and supportiveness, as well as ability to communicate clearly.

    There was one area in which men scored higher than women, though, and that was on emotional stability and ability to face job-related pressure and stress. The results suggested that women are more sensitive to the effects of high-pressure or highly emotional situations.

    Obviously, it's important to consider individual (个人的) differences. Anyone, regardless of gender, may be an inspiring leader and a competent boss. But next time you're hiring for a management position, you just might want to give the resumes(简历) from female candidates a harder look.

When Lamont Thomas, a retired restaurant employee, became an empty-nester, it was the end of a parenting story. A couple years ago, the divorced father of two became a hero when he took on a kid named Michael Perez in 2001.

"He was a good young man and I just hated to see him in the welfare system," Thomas said.

Thomas eventually adopted Perez, who now works as a nurse.

Perez was just the beginning. Over the next 15 years, Thomas raised more than 30 kids. He did so all as a single parent and with all of his heart.

"Every child that I have had, it was my goal to make a difference in their lives," he said.

When he retired from raising children to spend time fishing and traveling, that didn't last for long.

"It really was a shocker," Perez said. "I didn't expect for him to restart and to do it all over again. "

Thomas began to foster again when he found out that five brothers and sisters all under the age of 6 were going to be permanently broken up. To guarantee they stayed a family, he adopted all of them too.

"I had to help them. They deserved to be raised together," Thomas said.

After Thomas' story first aired, CBS News received a lot of surprising mail from women who expressed interest in the great man. Some notes weren't obvious, others were braver, "Ask Mr. Thomas if he would like a pen pal," wrote one woman, while another said, "I'll marry Lamont!"

But the kids see no room for romance, nor does Thomas.

"I was about to change my phone number," he said.

So he remains single. He spent Thanksgiving with family and is more grateful than ever.
