“A room without books is like a body without a soul,” observed the Roman philosopher, Cicero. It can also be a sign of financial problems to come. New research has uncovered a strong connection between the earning of adults and whether they grew up surrounded by books as children.

    Three economists at the University of Padua—Giorgio Brunello, Guglielmo Weber and Christoph Weiss—studied 6000 men born in nine European countries and concluded that children with access to books could expect to earn more money than those who grew up with few or no books.

    They studied the period from 1920 to 1956, when school reforms saw the minimum school leaving age raised across Europe. They booked at whether, at the age of 10, a child lived in a house with fewer than 10 books, a shelf of books, a bookcase with up to 100 books, two bookcases, or more than two bookcases.

    Over the period studied, the research, published in The Economic Journal, found that an additional year of education increased a man's average lifetime earnings by 9%. Men brought up in houses with less than a shelf of books earned only 5% more as a result of the extra year's education, compared with 21% more for those who had access to a lot of books. And those who had access to books were more likely to move to the better-earning opportunities in cities than those without books. The men's first job was also much more likely to be a white-collar job.

    The economists offer a number of theories for the results. “Perhaps books matter because they encourage children to read more and reading can have positive effects on school performance,” they said.

    The number of books in children's homes can effectively predict their cognitive(认知的) test scores. This may indicate a home that encourages cognitive skills, which are important for economic success in life.

    It used to be a matter of fact when Peter Pan – a character from James Matthew Barrie's 1911 book – said: “All children, except one, grow up.”

    But this “fact” doesn't seem to apply to today's world anymore.

    According to the NPD Group, a US market research company, sales of toys to adults in the UK increased by more than 20 percent in 2016, three times the pace of the children's toy market itself. These toys ranged from puzzles and Lego building sets to vehicle models and action figures. And more than half of the sales came from millennials – people born between the 1980s and 2000s.

    “Adults of the 21st century are channeling (疏导) their inner child, one toy at a time,” commented website Koreaboo. This is also why these adults are sometimes referred to as “kidults”.

    According to Frederique Tutt, an analyst at NPD, the motivation of these grown-ups is to escape the stress of today's fast-paced world. They are driven toward the more immediate pleasures brought by toys than those brought by, say, getting a promotion, which is far less easy to achieve.

    “It reminds me of the playful side of life,” Rob Willner, a 25-year-old PhD student in the UK, told The Telegraph when talking about his love for Lego, which he said brings him both comfort and entertainment.

    Despite this, some social scientists see the trend as disturbing. To Frank Furendi, a professor at the University of Kent in the UK, the fact that so many adults are pursuing “the thrills (刺激) of youth” is the evidence that “adulthood has got nothing attractive about it anymore”, he told The New York Times.u “That's actually quite sad.”

    But scientists are probably just worrying too much. According to Canadian comic book artist Todd McFarlane, collecting toys could simply be a way for people to express their individuality (个性).

    “It's just pop culture stuff. It's stuff that says, 'I like a little of this and I like a little of that',” he told ABC News. “[It's] no big deal.”

    So now that over 100 years have passed since Peter Pan, perhaps it's time to introduce a new “fact”, as stated in the tagline (品牌宣传词) of the UK fashion brand KIDULT: “Growing old is mandatory (强制性的), but growing up is optional.”

    An Unusual Setting

    Don't care about presentation? You'll be fine at the Modem Toilet restaurant in Taiwan. The theme of this restaurant is the toilet, and you would be surprised how many people queue up for the experience of eating on toilet seats.

    Someone sent me an email urging me to acquire a lot more resources, suggesting could do so much more good if I had an 8 or 9 figure net income of 6 like I've been doing for years. He claimed to have acquired a great deal of wealth himself and found it highly beneficial to fueling his path with a heart.

    As I consider his suggestion, I find myself not having much clarity(清晰的思维)as to what I'd do with I million or 10 million more money flowing through my life. I put so much attention on creativity, fulfillment, exploration, relationships, etc. that I find it difficult to intelligently imagine how more financial resources could provide extra fuel for that, except in small ways or in ways that aren't particularly meaningful to me.

    Lately I've been considering what it would be like to deliberately reduce my income for a while and see if I could live on much less，just for the experience. What if I capped my net personal income at $10,000 per year, for instance? That isn't such a big deal to me, though, since I already went through a period of low income like that during the 1990s, and I learned that I could still do what I love regardless of income.

    I've never worked in a business environment-the only job I've ever had was working for $6/hour in a video game store while I was in college. So I've never seen how larger operations allocate resources. That's probably why I haven't pushed myself to acquire more. As I mentioned in my book. Money and Your Path With a Heart，my main financial goal in life was to make money irrelevant in my life.

    I'm not interested in building an empire. What interests me is exploring personal growth and sharing what I learn along the way. In some ways I feel that acquiring and acquiring and allocating more resources could become a big distraction. I'm already doing what I want to be doing, so why rick distracting myself to acquire more resources, especially when I lack the idea about how I should treat such resources? I like having freedom and flexibility，and I don't really see how more resources would meaningfully improve that.

    The search engine Google celebrated on Thursday the 110th birthday of the first Native American woman engineer. Google honored Mary Ross with a special Google Doodle on its homepage.

    Ross was born on August 9, 1908, in the state of Oklahoma. She was the great-granddaughter of John Ross, the longest—serving chief of the Cherokee Nation. Her work is considered important to the early stages of the age of space travel.

    Ross showed special abilities in math and science from an early age. As a student, she developed an interest in aviation, or the practice of flying aircraft. She went on to earn a master's degree in mathematics from Colorado State Teachers College, now called the University of Northern Colorado.

    During World War II, Ross began working for the Lockheed Aircraft Corporation as a mathematician. She earned a special certification in the field from the University of California in1949.Ross was later chosen to join Lockheed's top—secret Skunk Works team that worked on aircraft designs. The name refers to a group that is permitted to work independently on advanced projects. She was the only female engineer among the team's 40 members.

    Early on, she researched defense systems. By the late 1950s, her work centered on satellites and a series of space rockets called Agenda. The rockets were extremely important in the 1960s during the Apollo moon program.

    Ross also helped develop early design ideas for space travel between planets, including flyby space flights to study Venus and Mars. Ross retired from Lockheed in 1973.But she continued to give talks at high schools and colleges to encourage more women and Native Americans to study engineering. She died in 2008, a few months before her 100th birthday.

    Many celebrated Ross' life on social media. Twitter user Aaron Perez, for example, wrote: “Mary Ross was an engineer who pioneered in the field of satellites. I never would have known if it wasn't for the doodle. Women engineers deserve more recognition.”

    Email has brought the art of letter writing back to life, but some experts think the resulting spread of bad English does more harm than good.

    Email is a form of communication that is changing, for the worse, the way we write and use language, say some communication researchers. It is also changing the way we interact(交流) and build relationship. These are a few of recently recognized features of email, say experts, that should cause individual and organizations to rethink the way they use email.

    "Email has increased the spread of careless writing habits, "says Naomi Baron, a professor of linguistics at American University. She says the poor spelling, grammar, punctuation(标点符号) and sentence structure of emails reflect a growing unconcern to the way we write.

    Baron argues that we should not forgive and forget the poor writing often shown in emails. "The more we use email and its tasteless writing, the more it becomes the normal way of writing," the professor says.

    Others say that despite its poor prose(文字), email has finished what several generations of English teachers couldn't: it has made writing fashionable again.

    "Email is a critical new communication technology," says Ian Lancashire, a University of Toronto professor of English." It fills the gap between spoken language and the formal methods of writing that existed before email. It is the purest form of written speech."

    Lancashire says email has the mysterious ability to get people who are scared by writing to get their thoughts flowing easily onto a blank screen. He says this is because of email's close similarity to speech." It's like a circle of four or five people around a campfire," he says.

    Still, he accepts that this new found freedom to express themselves often gets people into trouble. "Almost everyday I get emails that apologies of previous emails," he reports.

    In the US, the number of emails sent in a day exceeds(超过) the number of letters mailed in a year. But more people are recognizing the content of a typical email message is not often exact.
