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.

    Sharpshooters refer to those who are skilled at firing a gun and accurately hitting what they are aiming at. However, some fish are also called amazing sharpshooters. People wonder how they hit their targets without using tools? By spitting! The fish shoot so accurately that they rarely miss their target.

    These amazing fish are archerfish (印度射水鱼).There are several different types of archerfish living in Southeast Asia. They spit at their dinner to catch it. To catch dinner, a fish first sets itself in a certain place, for example just below the surface of the water. It puts the tip of its mouth so it barely breaks through the water. Then, the fish waits for an unsuspecting insect to land on a leaf or branch hanging over the water.

    When an unsuspecting, or unknowing insect lands, the fish attacks. The fish squeezes its gill (腮)covers very rapidly, which forces water into the fish's mouth. In the roof of its mouth the fish has a groove (槽）. The fish forms the small groove and its tongue into a narrow tube by pressing its tongue up against its groove. The water forced into the fish's mouth is forcefully pushed out of the fish's mouth through the tube. Archerfish have been known to send a stream up to 5 meters (16 feet). However, archerfish can only shoot insects up to 1-2 meters (3-6 feet) away due to their limited accuracy.

    When the unsuspecting insect is hit with a sudden stream of water, it is knocked into or falls into the water. Once in the water, the insect becomes dinner. Archerfish learn how to spit when they are young. They get more accurate with practice. Adult archerfish rarely miss.

    Within a meter, archerfish will often spring out of the water and grab an insect in their mouths.

    You've probably heard people expressing alarm about the spread of 'fake news' – stories that look like news articles but describe things that never happened. Fake news is written to attract attention, to trick people so they will look foolish, or to work as satire (讽刺) making a point about society. But regardless of the source's motivation, spreading fake news embarrasses you and harms others, so follow these steps to ensure you only share real news.

    Check its grammar

    Legal news sites check their grammar carefully, so articles with many errors are usually fake. Also watch out for sentences written in all capital(大写的) letters and the use of multiple exclamation points(感叹号) at the ends of sentences. These are designed to bring about an emotional reaction, but they aren't considered professional, so trustworthy publications don't use them.

    Read the whole article

    Even in real news articles, headlines sometimes overstate or simplify the point of the article. Before reacting, read the article carefully to make sure you understand the whole context. Sometimes the claims of fake news articles become unreasonable as the article goes on.

    Consider the source

    If you've never heard of the publication, check the 'About' section on its website. Fake news sites often lack such a page, provide little information or even admit that they are fake. Also check an online article's URL; if it ends with '.com.co', it's probably a fake news site.

    Check the support

    Does the article support its claims with quotations and citations(引用)from experts? If not, don't trust it. If so, you should still look up those sources and make sure they actually say what the article claims. There are also websites, such as snopes.com, that will tell you whether the facts in online articles are accurate.

    When Johnny, a homeless man, spent his last $20, he wasn't looking at it as an investment — but it's about to pay him huge profits. After he helped a woman who ran out of gas, she returned the favor by raising a lot more on the Internet.

    Kate McClure, 27, was driving to visit a friend when she ran out of gas halfway. “He saw me pull over and knew something was wrong,” she wrote. “He told me to get back in the car and lock the doors. A few minutes later, he came back with a red gas can, using his last 20 dollars to make sure I could get home safe.”

    She couldn't repay him at that time because she had no cash with her. “I have been stopping by his spot for the past few weeks. I repaid him for the gas and gave him some clothes.”

    Kate decided to do more for him, so she started a crowdfunding(众筹) campaign on GoFundMe.com, and it quickly gained far beyond its initial $10,000 goal. When it reached $100,000, the fundraising page was shut down for a time at Johnny's request. Because he didn't want to seem like he was taking advantage of the situation. Finally, Kate said that she restarted it because the public interest had not decreased. She also added that Johnny planned to donate the rest to a good cause.

    According to the New York Post  Johnny wants to get a job at an Amazon warehouse and a department manager from the tech company has already reached out, saying he wants to help Jonny.

    On a rainy winter day, several decades ago, a British artist named Christopher got on a train in Oxford to go to London. When he began his journey, he never knew that it was the beginning of almost 40 years of accidents and near death experiences.

    During the journey, the train fell into an icy river, killing 12 passengers. Christopher managed to swim back to the river bank. He only had a broken leg.

    Two years later, Christopher was on a plane from London to Manchester when a door suddenly opened and he fell out. A few minutes later, the plane crashed; 27 people were killed. Christopher was so lucky that he landed in a haystack (干草堆).

    A few years later, he was hit by a bus, but again had no serious injuries. Then a year after that, he was driving on a mountain road when he saw a truck coming straight at him. He drove the car off the road, jumped out, landed in a tree — and watched his car fall 100 meters down the mountain.

    "There are two ways you can look at it," Christopher said. "I'm either the worlds unluckiest man, or the world's luckiest." When a reporter asked Christopher what he thought, he chose the "luckiest" one.

    Two years ago, aged 71, Christopher bought his first lottery ticket (彩票) in 50 years and won more than 2 million. After this, a TV company in America said they wanted him to make an advertisement. At first he accepted, but then he changed his mind. Christopher said he would not fly to Los Angeles for the filming, because he did not want to push his luck. Who knows? If he had accepted the invitation, maybe he would have had another accident. But Mr. Christopher is a lucky man. If he had had another accident, he probably would have survived that too!
