The weather is getting hotter and you’ll be getting thirstier playing basketball or riding home from school. A cold drink may be just the thing. But be careful what you pour down your throat. Something that looks cool may not be good for your health.

There are plenty of so-called energy drinks on the market. Most of them have an attractive colour and cool name. Their nutrition list also contains various things from vitamins to ginseng. Sounds great!

But after a careful check you may find that most energy drinks contain high levels of caffeine. These drinks are typically aimed at young people, students, busy people and sports players.

Makers sometimes say their drinks make you better at sports and can keep you awake. But be careful not to drink too much.

Caffeine raises your heartbeat. Because of this, the International Olympic Committee has limited their use. The amount of caffeine in most energy drinks is at least as high as in a strong cup of coffee or strong tea.

Research by Australian scientists has found that many teenagers are affected by caffeine. The results of their survey show that 27 percent of boys aged 8-12 take in more caffeine than their parents.

There are potential health risks linked to energy drinks. Just one can of energy drink can make you nervous, have difficulty sleeping and can even cause heart attacks.

Teenagers should be discouraged from consuming drinks with a lot of caffeine in them, an expert from the Australia Nutrition Foundation said.

I live in New York City, and my “neighbors” are people I don’t know. My city, neighborhood and block are filled with people who don’t know me, don’t care to know me, and don’t talk to me. I find that it’s pretty hard to love people you don’t even know. And sometimes, we all, myself included, use that as an excuse not to try.

One day, Brendan, a young man in New York, was coming home to his Brooklyn apartment when a homeless woman called Jackie asked him for money. He said that he had no money. By the end of the week, she asked two more times, and each time he answered “No.” The woman looked sad, so Brendan said, “I am on my way to a job interview. If I get the job, I will take you out for Chinese food.”

Brendan got the job and carried out his promise. That was when their friendship began. They built a strong friendship by supporting each other and spending their birthdays, holidays and tough times together, over a period of eight years. When Brendan’s heater broke, Jackie made him a blanket. Two days later when he told her that he had lost his job, she disappeared, returning minutes later, bringing him food to eat. She continued to do throughout the winter. Even with so little, she never hesitated to give back.

Over these years, Jackie moved from the streets and subway stations, into a halfway house, and is now moving into an apartment. To celebrate it, Brendan wanted to do something special for Jackie. He went with her to Target, and helped her to pick out everything she’d need for her new apartment.

May Brendan’s story encourage us to find a new way to honor, serve and love the people around us.

Spring soccer season is under way, and many youth leagues are playing under new safety rules. In November, the US Soccer Federation said that players on its teams who are 10 or younger are no longer allowed to head the ball Players ages 11 to 13 have limits on how often they can practice heading. The new rules are made to prevent kids from getting concussions (脑震荡)—injuries caused by a blow to the head that shakes the brain. Common problems include headaches and dizziness. Severe concussions can lead to long brain damage.

Heading the ball can be one of the riskiest parts of soccer. Sometimes the force of hitting the ball with their heads gives players concussions. But more often, players receive concussions when they accidentally knock heads with other players and hit their heads on the grass. “More concussions happen during the act of heading than any other action in soccer,” explains Dr. Robert Cantu, an expert on brain injuries.

So far, the new rules are made only to teams that are part of the US Soccer Federation. But the group says it hopes other leagues will soon follow its example.

Former US soccer star Brandi Chastain is one of the leaders of the activity to ban heading in youth soccer. She applauds the rule change. Last month, Chastain showed her determination of learning more about the effects of heading when she promised to donate her brain to science after she dies.

“If there’s any information to be gathered on the study of someone like me，who has played soccer for 40 years, it feels like my responsibility,” Chastain told The New York Times.

When the telephone rings late at night, most women guess it must be one of only four or five people calling. A sister? Maybe. An emergency? Possibly. A mother? Probably not at that time of night. Much more probably it is a close female friend calling to tell you that she has split up with her boyfriend again or perhaps simply that a good movie has just started on TV.

At a time when families are spread far and wide and marriages often end in divorce, friendships are becoming more and more important. Erika, a 32-year-old lawyer, is strengthened by her ten-year friendship with her married friend Jane. “I was very sick one night, so I called Jane at about 3:00 a.m. to talk about it,” she says. “She was very supportive and even came over to take me to the doctor’s the next morning.”

As American TV shows like Friends, which follows the lives of a very close group of young friends, have become more popular, many of us are beginning to see the value of such friendships. TV shows like this tell us that our romantic relationships may not last, but we need to keep in touch with our close friends if we want to survive.

A TV show called Real Women is about the lives and relationships of five former school friends. In this show, family, husbands, and work are all less important than friendships. One of its actresses says the show reflects her own experience. “Friendship is about commitment. I don’t see some of my friends for ages but when we get together, it is as if time hasn’t passed.”

This is true of Erika and Jane’s friendship. With Erika’s family 200 miles away，it is Jane who keeps a spare set of keys to Erika’s apartment and waters her plants whenever she is away. “Having Jane around gives me a certain amount of freedom. It is not the kind of thing that you could ask anyone to do, but she knows I would do the same for her.” Erika feels that because she no longer sees her family every day, she now enjoys a closer relationship with her best friend. Jane, who may move to a different city soon, is worried about leaving such a support system of friends. “My friends have more to do with my life than my parents and, therefore, I don’t have to spend a lot of time explaining things to them. Friends are more up to date with what is happening.”
