You may have heard of the American Dream, an ideal that has powered the hopes of Americans for generations.

    It began as a belief that the US was a land of opportunity, and that anyone could achieve success through hard work. At times, the dream has referred to home ownership, a good job, retirement security or each generation doing better than the last.

    Yet today, this concept seems to have greatly changed. As Time magazine pointed out, quite different from the older generation, many Millennials (the generation born after 1980) redefine(重新定义) the American Dream as “day-to-day control of your life”. They “prize job mobility, flexible schedules, any work that is more interesting than typing, and the ability to travel”, said the magazine.

    Home ownership, once the cornerstone of the American Dream, is becoming a smaller priority for this generation. Meanwhile, nearly 40% of them choose travel as part of their dream. And entrepreneurship(创业) is a rising favorite, as nearly 26% of Millennials consider self-employment as part of their dream.

    So what has led to this huge change?

    Many point fingers at the poor economy. “Modern young Americans seem bound to face a world stamped by ever narrowing opportunity and social stagnation(停滞),”noted The Daily Beast.

    “The rate of 16-to 24-year-olds out of school and out of work is unusually high at 15%. Many college graduates have taken jobs that don't require a degree,” Time reported.

    The magazine worries that these difficulties may lead to a lost generation who are “unable to ever truly find their feet on the corporation's ladder”.

    Dan Kadlec, a reporter of Time, sees Millennials as resetting their expectations.”This situation is different for young adults today,” he wrote. “A true American dream has to feel attainable, and many Millennias are feeling they can only attain a day-today lifestyle that suits them.”

    When my sister Gina was born, she had a problem with her heart. Her heart was pretty bad in the beginning and she stayed in the hospital for a month. The first few years were very difficult because she was very sick. She had five operations before she was three years old. She had trouble walking, playing with other children, and going to school.

    Although Gina couldn't laugh and talk, we all knew that she just needed love and care. Our parents wanted to take Gina to a special place in Florida where she could swim with dolphins. Gina was afraid of swimming with them because she had never been around dolphins before. We had also never traveled that far as a family.

    When we got to Florida, we saw where the dolphins lived. It was a place where kids with special needs like Gina could come and spend time. I thought it was going to be a vacation, but it wasn't. Gina had to work hard every day for a week.

    The trip was amazing .Gina laughed and clapped(拍手) when she saw the dolphin, and the dolphin splashed (溅起水花) when it saw Gina. They swam together all day. Gina was able to move her body more than she normally did at home. Mom and dad were proud of Gina. I was, too.

    Two weeks ago, Ray Johnstone, an elderly man living alone in South Australia, posted a classified advertisement in search of a friend. Specifically, he was on the hunt for a fishing partner, as he no longer had anyone to share his hobby with. “I'm a widowed retired man who is looking for a fishing mate,” he wrote on Gumtree, “My previous fishing mate is now deceased. He will never accompany me to go fishing. I am a land-based fisherman. I have all the gear for all types of fish that is required for land-based fishing.”

    Like all of us, 22-year-old Mati Batsinilas was touched by the man's advertisement, so he reached out to him and arranged an outing. Rather than simply spend the day with Johnstone somewhere local, however, he and his family offered to take him on an all-inclusive weekend fishing trip of Stradbroke Island in Queensland. And, as expected, they had a good time. “Whilst on the island we covered four-wheel driving, site-seeing, fishing, swimming, chats with the locals and the best of all... just relaxing and chatting like mates,” Batsinilas wrote in a Facebook post. “Once you reach a level of maturity in life, age should only be a number. My respect for Johostone is obviously very high, but I treated him exactly the way I would have treated one of my 22-year-old mates.”

    Fortunately, it sounds like Johnstone won't have to place more classified advertisements any time soon. In addition to finding a friend, the pensioner has become a star on the Internet, with many social media users voicing their interests in meeting the now-famous fisherman.

    It was Sunday, so Dad and I were at the second-hand goods market, looking for tools, appliances(家用电器), and other things that needed cleaning. Some were broken; others, like silver cups, just needed to be cleaned and polished. It was 1974, and the Depression(经济大萧条) was very serious. Dad worked full-time at a factory, but the money wasn't enough. Dad had tried a second job for a while, but he found it was too hard on the family. One day, he had an excellent idea that set me on a lifelong course of making money to support myself. Standing beside a crowded table at the second-hand goods market, I looked over an ancient manual sewing machine. Someone had changed it to run on electric power. It was much older than Mom's machine, but it looked like it had quality and a long life built into it. "Dad!" I called. "This is a beauty!"

    Dad walked over, pulling a cart full of audio equipment, tools, worn-out appliances, and what appeared to be a block of dull kitchen knife." What have you got, Son?" I described what I saw and what I figured I could do to x the beauty up. Dad paid for my discovery, and we headed home.

    Every day after school I worked on the ancient machine, and every night Dad and I sharpened tools and knives, sanded off rust, polished metal, and replaced missing parts from various items. The next Saturday we headed off, as we did every weekend, to that same market, where we sold the treasures we'd purchased the week before—at a tidy profit. My antique beauty brought in more money than anything else, and Dad let me keep every penny.

    Dad's gone now, but I can never thank him enough. Even if we hadn't needed the extra money Dad and I brought in, I wouldn't have traded those weekends for all the picnics or Little League games in St. Louis—not in a million years.

    Exercise is known to benefit people's mental health, but scientists recently discovered that too much exercise may have a negative effect on it.

    The researchers studied about 1.2 million people in the United States in 2013, 2015 and 2017. The participants, on average, experienced 3, 4 days of poor mental health each month. Those who did exercise experienced 1, 5 fewer days of poor mental health per month, compared to those who didn't exercise at all. The team found that people who exercised for 30 to 60 minutes three to five times a week had the best mental health, but those who exercised for more than three hours had worse mental health than those who didn't exercise at all.

    The scientists think that people who exercise so much may experience poorer mental health because that much exercise can be a sign of obsessive (强迫症患者) behaviors that have been associated with poor emotional and psychological outcomes. However, the only mental health disorder that the researchers looked at was depression.

    Among those who had been diagnosed with depression, people who did exercise experienced 3.75 fewer negative mental health days than those who did not, showing an ever greater difference, According to the Centers for Disease Control and Prevention. 7, 6 percent of people in the U.S. age 12 and over have depression. While all types of exercise appeared to help with mental health, cycling, gym-based exercise and team sports were the most beneficial.

    The team also looked at more specific factors, like education. People with a college education reported 17.8 percent fewer days of poor mental health than those without that level education Additionally, people in a healthy BMI (体重指数) range reported a 4 percent reduction in poor mental health days thin those whose BMIs were high. Even salary was a factor: compared to people with bower salaries, those with higher salaries experienced a 17 percent reduction in poor mental health days.

    The study showed that exercise can help with mental health, but that in some cases, limiting it may be necessary.
