As we age, our ability to think and remember starts to deteriorate. But not everyone. Some of us have brains that age more slowly. Enter the super-ager!

    Super-agers are people over the age of 80 who have the brain structures and abilities of much younger people. Eighty-seven-year-old Bill Gurolnick is a super-ager. “What do I feel like? If I was to give a number, I probably feel like I'm about my early 70s…”

    Scientists know that parts of the brain decrease in size with age. But in super-agers that process is much slower. Emily Rogalski is a neuroscientist at Northwestern University's Feinberg School of Medicine, in Chicago, Illinois. In a recent study, she showed that super-agers have young brains. The area of the brain responsible for attention and memory—the cortex—was shown to be thicker in super-agers. “When we look at the cortex of their brain, we see that, on average, that it looks more like a 50-year-old brain that it looks like an average 80-year-old bran…”

    Not only do super-ages have thicker cortexes, they have more spindle neurons. These large brain cells appear to be involved with social-emotional communication. But their exact purpose is still a mystery. Scientists writing for Smithsonian magazine say they are “brain cells for socializing.”

    Several factors affect how our brains age. Scientists say super-agers have several things in common, including an active lifestyle. Many travel and play sports. They are often big readers. And they usually have healthy relationships and spend time with friends. Super-agers also seem to have certain common personality traits. Rogalski says they are, for the most part, known for their optimism, resilience and perseverance. Growing old, she adds, does not have to be depressing and sad. “Perhaps, if we expected a bit better from ourselves, then we would understand that not all aging is stressful!”

    Can we all be super-agers? The science behind super-aging is a relatively new, but growing field. Scientists involved in the research offer this advice as we age: Stay active. Learn new things. Challenge yourself. Surround yourself with healthy relationships.

    Superman, Spider-Man, Batman and Iron Man ... .There is no shortage of superheroes. You find them in comic books, on TV and the big screen.

    In a survey of fans by the sci-fi（科幻）and fantasy website, SFX.co.uk, Batman, 70 years old this year, was voted Britain's favorite superhero.

    Unlike many crime-fighting superheroes Batman has no special powers. He can't fly like Superman or shoot a sticky web like Spider-Man.

    Bruce Wayne is born to a wealthy Gotham City business family. However, when his parents are murdered his life changes completely.

    Wayne feels angry at their deaths and guilty that he did not prevent them. He travels around the world learning how to fight. Upon returning to Gotham, he creates a disguise (伪装) to enable him to fight crime without being recognized.

    A childhood fear of bats leads him to choose to dress as one. His idea is that through the bat persona (角色) he can prove to himself that he has overcome his childhood fears.

    Wayne is the CEO of the company he inherits from his father. He seems to live the lifestyle of a millionaire playboy. But this is a ruse (计策). He works hard at the image to allow himself the freedom he needs to do his work as a crime fighter. "Bruce Wayne, playboy" is the disguise; Batman is the real person.

    "Wayne is not a born superhero. Instead, he is a real, complex person," said Dace Golder, editor of the website. "He is the most realistic of all the superheroes. I am particularly interested in the emotional process by which a boy becomes a hero. His superhero qualities come from within."

    Philadelphia offers a ton of attractions that are suitable for people of every age and here are some family—friendly attractions.

    Spruce Street Harbor Park

    Spruce Street Harbor Park, one of the best urban beaches in America, is an outdoor heaven on the Delaware River waterfront. Visitors can relax in a hammock, play on the playgrounds, and play games like table tennis and giant chess. Don't miss out on the park at night, when colorful LED lights hanging from treetops make the entire area bright.

    Blue Cross River Rink

    Offering ice skating in the winter and roller skating in the summer, Blue Cross River Rink creates a fun, outdoor experience for the whole family. Visitors can play on the nine-hole mini-golf course during the summer, and enjoy eats and drinks from the on-site(现场的)bar and restaurant all year round.

    Sesame Place

    Big Bird, Elmo and the other stars of Sesame Street come out and play at Sesame Place, the only theme park in the nation starring the popular TV show's most lovable characters. A water park, interactive activities, parades, fireworks and shows add to the fun.

    Once Upon a Nation Storytelling Benches

    On summer days, uniformed and professional storytellers at 13 storytelling benches throughout Philadelphia's Historic District entertain visitors with true, free, three-to-five minute tales about the colonial(殖民的)era as part of Once Upon a Nation. Children can pick up a Story Flag at any storytelling bench, and then collect a star from every storyteller on their journeys. Flags with all the stars can get free rides on the Parx Liberty Carousel at Franklin Square.

    Located in the checkroom in Union Station as I am, I see everybody that comes up the stairs.

Harry came in a little over three years ago and waited for the passengers from the 9:05 train.

    I remember seeing Harry that first evening. He wasn't much more than a thin, anxious kid then and I knew he was meeting his girl and that they would be married twenty minutes after she arrived. The passengers came up and I had to get busy. I didn't look toward the stairs again until it was nearly time for the 9:18 train and I was very surprised to see that the young fellow was still there.

    She didn't come on the 9:18 either, nor on the 9:40, and when the passengers from the 10:02 had all arrived and left, Harry was looking pretty desperate. He showed me the telegram he'd received: ARRIVE THURSDAY. MEET ME STATION. LOVE YOU. MAY.

    Harry met every train for the next three or four days, but in vain.

    Then came yesterday. I heard a cry and found that it was from Harry. He grabbed a girl who was small and dark. For a while they just hung there to each other laughing and crying and saying things without meaning. She'd say a few words like, "It was the bus station I meant" and he'd kiss her speechless and tell her the many things he had done to find her. What apparently had happened three years before was that May had come by bus, not by train, and in her telegram she meant "bus station," not "railroad station." She had waited at the bus station for days and had spent all her money trying to find Harry. Finally she got a job typing.

    "What?" said Harry. "Have you been working in town? All the time?"

    She nodded.

    "Didn't you ever come down here to the station?" He pointed across to a magazine stand. "I've been there all the time. I own it. I've watched everybody that came up the stairs."

    She began to look a little pale. Pretty soon she looked over at the stairs and said in a weak voice, "I never came up the stairs before. Harry, for three years, for three solid years, I've been right over there working right in this very station, typing, in the office of the stationmaster."

    The Origins of Famous Brands

    Our lives are full of brand names and trademarked products that we use every day. Although many brand names are simple acronyms(首字母缩略词) or versions of their founders' names, some of the companies we trust every day actually have fascinating and surprising back stories.

    Starbucks

    It seems fitting that the most famous coffee brand in the world would take its name from one of the world's greatest works of literature. The inspiration for the name of the coffeehouse came from Herman Melville's Moby Dick. The founders' original idea was to name the company after the Captain Ahab's ship — Pequot, but they eventually decided that Pequot wasn't a great name for coffee, so they chose Ahab's first mate, Starbucks, as the name instead.

    Nike

    Originally founded as a distributor for Japanese running shoes, the company was originally named BRS, or Blue Ribbon Sports. In 1971, BRS introduced its own soccer shoe, a model called Nike, which is also the name for the Greek goddess of victory. In 1978, the company officially renamed itself as Nike, Inc.

    The right name is essential to a company's success, and a great origin story is just as crucial as a great product. An attractive origin story is one more thing that keeps customers guessing, wondering, and buying its products.

    Google

    Google was originally called BackRub, for it searched for links in every corner of the Web. In 1997, when the founders of the company were searching for a new name showing a huge amount of data for their rapidly improving search technology, a friend suggested the word "googol". When a friend tried to register the new domain name, he misspelled "googol" as "google".

At just seven years old, Angelina Tsuboi discovered her passion for innovation. It all began with a simple game she programmed in her Los Angeles public school's Grade 2class. Today , at18, the Grade 12 student's initial curiosity has evolved into a deep-seated desire to use technology to decode (解码) real-world problems. 

In 2021, she co-developed Megaphone, one of her first apps, to tackle unanswered post-class questions and poor communication about events and announcements. Her problem-solving ability kept building from there. 

When she took online CPR classes at the start of the pandemic, she figured it couldn't be just her who was struggling with the steps. So she created an app called CPR Buddy ― a winner in the 2022 Apple Swift Challenge ― which guides users through CPR using vibrations (震动) to regulate breath. After winning the award, Angelina presented her work to Apple CEO Tim Cook, a highlight in her young career, but one she didn't lose her cool over. "There's no point putting people on a pedestal (神坛)," she says. 

The next year, Angelina built an app called Lilac, designed to assist nonEnglish-speaking single parents with resources for housing, job opportunities and translation support. She was inspired by her own experiences as a child of a single mother who immigrated to the US. 

When Angelina decided to pursue pilot training at the age of 16, she was struck by how difficult it was to find financial support, which encouraged her to create yet another app, Pilot Fast Track, which helps those longing to be pilots find scholarships for flight training. 

Looking to the future, besides applying to colleges with great labs, Angelina is exploring the field of aerospace cybersecurity and mechatronics ― combining computer science, electrical engineering and mechanical engineering. 

"There's not enough optimism in the world," she says. "I have also been in situations in my life where I've lost a lot of hope. But in the end, it is a mindset, and there are ways in any situation you're in to make it somewhat better. "
