1 . A new study shows that getting half of American 8-to 11-year-olds into 25 minutes of physical activity three times a week would save ＄21.9 billion in medical costs over their lifetimes.

The increase from the current 32 percent to 50 percent of kids taking part in exercise, active play, or sports would also result in 340,000 fewer overweight teenagers.

“Physical activity not only makes kids feel better and helps them develop healthy habits, it’s also good for the nation’s bottom line,” says Bruce Y. Lee, executive director of the Global Obesity Prevention Center at Johns Hopkins University. “Our findings show that encouraging exercise and investing in physical activity when kids are young pays big dividends as they grow up.”

The study, published in the journal Health Affairs, suggests an even bigger advantage if every 8 to 11-year-old in the United States exercised 75 minutes over three times in a week. In that case, the researchers estimate (估计), ＄62.3 billion in medical costs over the course of their lifetimes could be avoided and 1.2 million fewer youths would be overweight. And the money would increase if not just current 8-to-11 year olds, but every future elementary school child joined their game.

Exercise at least 25 minutes a day, three days a week, is a guideline developed for kids by the Sports and Fitness Industry Association. An overweight person’s lifetime medical costs average ＄62,331. For the overweight person, these amounts are great.

“Even a little increase in physical activity could cause billions of dollars in savings,” Lee says. He also says there are other benefits of physical activity that don’t affect weight, such as improving bone density, improving mood, and building muscle.

Lee says “We need to be adding physical education programs and not cutting them. We need to encourage kids to be active, to reduce screen time and get them running around again. It’s important for their physical health and the nation’s financial (经济的) health.”

2 . Now, new research suggests frequent exercise might help you live well in another meaningful way—that is, in terms of income. Researchers investigated whether individuals who stayed active would earn more money as a result of their active lifestyle. It revealed that staying active not only resulted in higher present earnings, but also predicted increased future income throughout one’s life.

The researchers set out to explore three key correlations (相互关系)：How mobility-the ability to move, affected income, how mobility influenced income overtime, and whether exercise could help people maintain their mobility as they aged. The team analyzed data from Health and Retirement Study(HRS), the largest study tracking changes overtime in Americans aged 50 and above. This study takes into account various life aspects, including work, social status, health, psychology and family matters, as individuals age.

To evaluate the impact of current mobility on income, the researchers examined data from over 19, 000 respondents (调查对象) to determine how well they could perform simple tasks, such as climbing stairs, or moving around a room. Each person received a score, with 5 indicating full mobility and 0 indicating difficulties with these tasks. The researchers found that for each decrease in the mobility category, individuals lost out on an average of $3, 000 in annual income compared to their peers. Those who were active were also significantly more likely to remain working for longer than the other group. It appeared that engaging in exercise enabled individuals to maintain mobility and engage in professional life for a longer period of time than those who were less active.

Looking at earnings overtime revealed even more substantial benefits for those who remained active throughout their lives. Active individuals showed an overall income level that was $6, 500 higher, along with higher rates of employment. For the third part of the study, it’s not surprising that those who engaged in exercise continued to maintain their mobility after the age of 55 and had higher employment rates. Even exercising just one day a week showed improvements in mobility outcomes.

While this study doesn’t definitively prove that leading a healthy lifestyle directly leads to higher earnings, it strongly suggests that staying healthy and mobile brings benefits beyond just lower levels of disease.

4 . According to research, about 21.5 million American children between the ages of six and seventeen are involved (参与的) in a team sport.     1     But regardless of the reasons for getting involved, children can gain a lot from sports.

A 2006 report shows that taking up sports can increase both emotional and behavioral well-being in teenagers. And increased well-being can lead to higher confidence, which results in better overall performance.     2     In addition, they usually get along well with people around them and are less likely to have bad or risky behavior.

    3     Through this process, children develop social and leadership skills and learn the value of teamwork. Children involved in sports usually have stronger and better relationships with their schoolmates and a better understanding of people from different backgrounds.

Actually, sports give children an opportunity to communicate with adults in valuable and positive ways, which can help them develop closer relationships with adults. This effect is especially great when children don’t get along well with their family members.     4    

Although most effects of sports on children are good, there can be disadvantages. If the pressure to win is overemphasized (过分强调) or the expectations of parents or coaches become too great, kids may experience lots of stress.     5     To avoid these bad effects, children should not overemphasize winning but focus on developing certain skills.

A．Being physically fit is linked to having a higher IQ.

B．They may take part in sports for fun or to develop some skills.

C．However, children hardly play sports when they become older.

D．It can cause worries, headaches, stomach aches, and muscle pain.

E．For example, children involved in sports are likely to do well in their studies.

F．Organized sports require children to work together to achieve a common goal.

G．Many children say sports have helped increase their conversations with parents.

8 . I love training with my husband Chris. We do our own exercises separately, but then we really enjoy spending 30—40 minutes doing something we both like together. I also train with my family — my brother, his wife and our cousins will come to our house every now and then to train together. It's like family fun time! A little bit of competition also makes us work out harder.

Laziness, as you know, is contagious. But so is enthusiasm. If you can get your partner on board, you will be able to encourage each other on those days when the other doesn't feel like moving. If you set yourself a challenge and add competition to the mix, I promise you that the training will be much more fun. Time will fly by and you'll want to do it again.

This is why I wanted to learn Chris' favourite sport — surfing. Not only would we have more things to do together, but it would be a great challenge for me. In turn, I have introduced Chris to two of my favourite activities: horse riding and motorbiking. Now he also loves them, which means we have even more chances to have fun together. Encouraged by our example, my brother and his wife now train together too. This is what it's all about at the end of the day: quality time with your partner.

What if you don't have a partner? Well, I'm sure you have a friend who would love to train with you. Or, if you have young children, why not train in the backyard with another parent while they play? You just need some music. The important thing is to have a plan and to make the time to do it. It will be much more fun than doing it on your own.

10 . The Biggest Stadiums in the World

People have been pouring into stadiums since the days of ancient Greece. In around 80 A.D., the Romans built the Colosseum, which remains the world’s best known stadium and continues to inform contemporary design. Rome’s Colosseum was 157 feet tall and had 80 entrances, seating 50,000 people. However, that was small fry compared with the city’s Circus Maximus, which accommodated around 250,000 people.

These days, safety regulations-not to mention the modern sports fan’s desire for a good view and comfortable seat — tend to keep stadium capacities (容量) slightly lower. Even soccer fans tend to have a seat each; gone are the days of thousands standing to watch the match.

For the biggest stadiums in the world, we have used data supplied by the World Atlas list so far, which ranks them by their stated permanent capacity, as well as updated information from official stadium websites.

All these stadiums are still functional, still open and still hosting the biggest events in world sport.
