Inside the pleasingly fragrant café, So All May Eat(SAME) in downtown Denver, the spirit of generosity is instantly noticeable: A donation box stands in place of a cash register. Customers here pay only what they can afford, no questions asked.

    A risky business plan, perhaps, but SAME Café has done one unchangeable thing in the Mile High City for six years: Open only at midday, the restaurant provides poor local people with healthy, delicious lunches six days a week. Those unable to pay for their meals can instead volunteer as waiters and waitresses, and dishwashers, or look after the buildings and equipment for the cafe.

     “It's based on trust, and it's working all right” , says co-owner Brad Birky , who started the café in 2006. With his wife Libby. Previously volunteering at soup kitchens, the Birkys were dissatisfied with the often unhealthy meals they served there.

     “We wanted to offer quality food in a restaurant where everyone felt comfortable ,regardless of their circumstances,” Birky says. SAME's special lunch menu changes daily and most food materials are natural and grown by local farmers.

    The café now averages 65 to 70 customers (and eight volunteers) a day. And the spirit of generosity behind the project appears to be spreading. In early 2007,one volunteer who had cleared snow for his meals during the long winter said goodbye to the Birkys,” He said he was going to New Orleans to help with the hurricane cleanup,” says Birky.

    Two summers ago I was about to turn fifty and wanted to do something I'd never done before. My daughter Bailey thought skydiving (跳伞) would be perfect for me. I can promise you that of all the things I was thinking of doing, jumping out of an airplane never came close to making the list. As I age, I seem to have developed a growing fear of heights.

    After several requests from my daughter, I finally said yes and she looked almost shocked. I told a friend what we were doing, then we set off. We had a 3-hour drive to the jump site. We drove through some beautiful countryside, but then we passed a small cemetery(墓地). Then we passed another cemetery and another one. I asked if so many people died jumping out of airplanes in this area that they needed to keep building more cemeteries to bury all the bodies!

    As we squeezed into the little plane, I tightly held the right hand of my partner Ronnie. The short ride to altitude was cruel for me. As Bailey stepped to the door, she looked back at me and said “Dad, I'm sure you can do it!” I said yes as she rolled out. I immediately looked behind me and said “RONNIE I AM NOT FEELING GOOD!” He said, “It's going to be great. Besides, it's too late now anyway”, and we jumped out.

    The next five minutes were some of the most amazing of my life. It was so beautiful and peaceful—except for the parts where I was screaming. I prayed to God for the parachute (降落伞) to open, but mostly I told Him how thankful I was for my life and being with me through good and bad.

    Black Friday-the day after Thanksgiving Day in the United States-signals the beginning of the holiday shopping season. Although it's not an official holiday, millions of employers give their employees the day off, and many people use that day to get a jump start on their holiday shopping. A similar day in Canada and the Great Britain is called "Boxing Day".

    Black Friday has become a marketing sensation in recent years. Since 2005, it has been the busiest shopping day of the year. To lure shoppers, retailers（零售商）routinely open their doors as early as 4 am and offer special sales and promotions to the shoppers that arrive early. Some of the special deals offered by stores are only available in limited quantities. That is why some shoppers intend on getting the best deals often camp out in front of stores overnight so that they will be the first in line when the doors open.

    But why Black Friday? Historians believe the name started in Philadelphia in the mid 1960s. Bus drivers and police used "Black Friday" name. In the early 1980s, a more positive explanation of the name began to ciculate. According to this alternative explanation, Black Friday is the day when retailers finally begin to turn a profit for the year. In accounting terms, operating at a loss is called being "in the red" because accountants traditionally used red ink to show negative amounts. Positive amounts were usuallay shown "in black ink". Thus, being in the black is a good thing because it means stores are operating at a profit.

    Recently, for those who are too busy to stop on Black Friday, or who just don't want to fight the crowds, the Monday following Black Friday has become known as Cyber Monday for shoppers can take advantage of the comfort of getting many online deals from their homes.

    While staring out of the window during a flight, not everyone will think carefully about the question why airplanes have rounded windows rather than square ones.

    Over the years, aerospace engineering has made huge steps in airplane technology, meaning planes can carry more passengers and go faster. The planes have also changed shape to increase safety—including the windows. As commercial air travel took off in the mid－20th century, airline companies began to fly at higher altitudes to lower their cost—the air density(密度) is lower up there, creating less drag(阻力)for airplanes. However, higher altitudes came with problems, like the fact human beings can't really survive at 30，000 feet. To make that possible, the cabin was changed to a cylindrical(圆柱体) shape to support the pressure inside. But at first, plane builders left in the standard square windows and this expansion meant disaster. The de Havilland Comet came into fashion in the 1950s. With a closed cabin, it was able to go higher and faster than other aircraft.

    However, where there's a corner, there's a weak spot. Windows, having four corners, have four potential weak spots, making them likely to crash under stress—such as air pressure. By curving the window, the stress that would eventually break the window corner is distributed and the chance of it breaking is reduced. Rounded shapes are also stronger and resist deformation(变形), and can thus survive the extreme differences in pressure between the inside and outside of the aircraft.

    Fortunately, designers figured out the lack of design pretty quick. Now we have nice, rounded airplane windows that can resist the pressure of traveling altitude. It gives being able to gaze out of your window to the world from 35，000 feet a whole new outlook, doesn't it?

The American Psychological Association（APA） has issued its first advisory on social media use in adolescence（青春期）. What's most striking in its data based on recommendations is how little we really know about how these apps affect our kids.

The relative newness of platforms like Snapchat and Tik Tok means little research is available about their long-term effects on teen and tween brains. Getting better data will require significant funding—and much more openness from tech companies.

"What little evidence we do have unsurprisingly suggests that social media trades on motivators that aren't great for young brains. Many kids' first exposure to social media occurs at the worst possible time when it comes to brain development," says Mitch Prinstein, a psychologist and neuroscientist at the University of North Carolina（UNC）.

"Things like 'button and artificial intelligence（in general）' are going to affect young people's brains in a way that's very different from adult brains when it comes to the desire to stay online and to say or do almost anything to get followers." When it comes to social interactions, he compares kids' brains to a car with a huge gas pedal and weak brakes（刹车）.

Earlier this year, Prinstein and his UNC colleagues published the results of one of the first studies of how the adolescent brain reacts to social media. The team surveyed a group of middle schoolers to understand their social media habits, and then stuck them in an MRI machine to watch their brains as they reacted to social rewards or punishments. They found that 12-year-olds who habitually checked social media had distinct neural patterns, with more activities over time in parts of the brain associated with motivation, salience（or where attention is focused） and cognitive control.

The team didn't weigh in on whether those differences were good or bad, or whether the relationship was causal or correlational. But their work points to the need for more research. It should also remind parents of the need to be keenly aware of social media's hidden influence on still-developing brains.
