【推荐3】More than 60 years and almost 1,200 donations later, Harrison, whose blood contains an antibody (抗体) that has saved the lives of 2.4 million babies from miscarriages (流产), retired as a blood donor on May 11. Harrison’s blood is valuable because he naturally produces Rh-negative blood, which contains Rh-positive antibodies. His blood has been used to create anti-D in Australia since 1967.

“Every bottle of anti-D ever made in Australia has James in it,” Robyn Barlow, the Rh program director told the Sydney Morning Herald. “It’s an amazing thing. He has saved millions of babies. I cry just thinking about it.” Since then, Harrison has donated between 500 and 800 milliliters of blood almost every week. “I’d keep going if they let me,” Harrison told the Herald. His doctors said it was time to stop the donations. They had already extended the age limit for blood donations for him, and they’re cutting him off now to protect his health.

【推荐1】During the rosy years of elementary school(小学), I enjoyed sharing my dolls and jokes, which allowed me to keep my high social status. I was the queen of the playground. Then came my tweens and teens, and mean girls and cool kids. They rose in the ranks not by being friendly but by smoking cigarettes, breaking rules and playing jokes on others, among whom I soon found myself.

Popularity is a well-explored subject in social psychology. Mitch Prinstein, a professor of clinical psychology sorts the popular into two categories: the likable and the status seekers. The likables’ plays-well-with-others qualities strengthen schoolyard friendships, jump-start interpersonal skills and, when tapped early, are employed ever after in life and work. Then there’s the kind of popularity that appears in adolescence: status born of power and even dishonorable behavior.

Enviable as the cool kids may have seemed, Dr. Prinstein’s studies show unpleasant consequences. Those who were highest in status in high school, as well as those least liked in elementary school, are “most likely to engage(从事)in dangerous and risky behavior.”

In one study, Dr. Prinstein examined the two types of popularity in 235 adolescents, scoring the least liked, the most liked and the highest in status based on student surveys(调查研究).＂We found that the least well-liked teens had become more aggressive over time toward their classmates. But so had those who were high in status. It clearly showed that while likability can lead to healthy adjustment, high status has just the opposite effect on us."

Dr. Prinstein has also found that the qualities that made the neighbors want you on a play date——sharing, kindness, openness — carry over to later years and make you better able to relate and connect with others.

In analyzing his and other research，Dr. Prinstein came to another conclusion: Not only is likability related to positive life outcomes, but it is also responsible for those outcomes, too. "Being liked creates opportunities for learning and for new kinds of life experiences that help somebody gain an advantage," he said.

【推荐3】Mr Titterton is chairman of the Omega Ensemble but has been the group’s official page turner for the past four years. His job is to sit beside the pianist and turn the pages of the score so the musician doesn’t have to break the flow of sound by doing it themselves. He said he became just as nervous as those playing instruments on stage.

“A lot of skills are needed for the job. You have to make sure you don’t turn two pages at once and make sure you find the repeats in the music when you have to go back to the right spot.” Mr Titterton explained.

Being a page turner requires plenty of practice. Some pieces of music can go for 40 minutes and require up to 50 page turns, including back turns for repeat passages. Silent onstage communication is key, and each pianist has their own style of “nodding” to indicate a page turn which they need to practise with their page turner.

But like all performances, there are moments when things go wrong. “I was turning the page to get ready for the next page, but the draft wind from the turn caused the spare pages to fall off the stand,” Mr Titterton said, “Luckily I was able to catch them and put them back.”
