When we say older people shrink,we don't mean they become tiny enough to fit in your pocket!We just mean that it's common for older people to become a little shorter over time.This kind of shrinking can't be stopped, although people can slow this process.But why does shrinking happen at all?

    Because of gravity,cushions between the bones in the spine（脊骨）get compressed（压缩）,which makes a person lose a little height and become shorter.

    Another reason why some older people shrink is because of osteoporosis（骨质疏松）.Osteoporosis occurs when bone is broken down and not enough new bone material is made.Over time,bone is said to be lost.Bones become smaller and weaker and can easily break if someone with osteoporosis is injured.

    Older people—especially women,who generally have smaller and lighter bones to begin with—are more likely to develop osteoporosis.As years go by,a person with osteoporosis can get small breaks in bones that are called compression fractures.These breaks cause collapse of the spine and over time the person with osteoporosis can become hunched over（驼背）.

    Did you know that every day you shrink a little,too?You aren't as tall at the end of the day as you are at the beginning.That's because as the day goes on,water in the disks of the spine gets compressed due to gravity,making you just a tiny bit shorter.Don't worry,though.Once you get a good night's rest,your body recovers,and the next morning,you're standing tall again!

    Smoking and drinking alcohol can make this problem worse.Want to do something right now to build strong bones?I believe what I say will help you.

    I considered an active social life as basic human necessity. Yet when it dawned on me just how much time I was spending socialising, I realised I may be taking it to an extreme. I calculated that, on average, I was spending 22 hours or more each week on social activities. So, to see what would happen to my work output, health and wellbeing, I decided to try and cut out my social life entirely.

    I knew, at times, I filled my schedule simply out of fear of missing out (FOMO), but also as a way to shift focus away from my work. For one month, I declined all in-person activities with friends: going out for drinks; dinners; parties and non-work related events, to see if it would make me more productive, improve my focus and career prospects.

    On day one of the month-long experiment, I had to fight some anxiety over missing out. But as the days passed, I started to relax. I only had one option to consider for Saturday night—to stay home—and this limitation left me more satisfied in my decision. I felt more content working, reading or watching TV.

    While I found more time to work, I also noticed a change in my overall health. I found myself cooking more at home, doing daily exercise, getting to bed earlier each night, reading, and enjoying moments of rest and boredom throughout the day.

    Having no social life left me more free time than I'd imagine. Such idle moments are vital for creativity, and mind wandering has been linked to creative problem solving. During the experiment I found myself regularly brainstorming new ideas and reimagining existing projects.

    Of course socialising is an important way to build work contacts. While one month of no social life did not impact my relationship with existing clients, if I had continued, it may harm my ability to build new ones.

    My dad is the kind of parent that expects my best. He would never be angry if I failed at something as long as I tired. He never changes his mind after he makes it, which sometimes makes him seem too stubborn. My dad's strictness comes from the way he was raised. He grew up working long hours on his family farm. His dad was bad-tempered, and he would get angry enough to throw wooden boards at my dad when he did something wrong. In high school, my dad woke up at four in the morning to get his chores(家务杂事)done and walk to school so that he would make it to basketball practice by five.

    Through all of the duties my dad had at home, he played three sports and went to school on top of it. school would have been easy, but my dad had dyslexia(读写困难)which made it nearly impossible for him to read. Since dyslexia wasn't recognized back then, every teacher my dad had passed along thinking that he was just unable to learn. My dad struggled in school until one teacher took the time to sit down and teach him how to read and write.

    The best part about my dad is his attitude toward daily life. even though he likes things once right, he also knows how go to with the flow and have a good time. My dad doesn't worry about things he can't control. When he comes home from a terrible day at work, he always puts on a smile on his face because he knows family is a lot more important than any other tings.

    I know that I get my best qualities from my parents and the way they raised me. My dad has shown me that with discipline and hard work I can achieve anything, and have fun while doing it.

    The morning after an evening struggle to care for my three-year-old daughter, I couldn't wait to get her to school. I, as a mother, was tired from the anger and her inability to communicate because of her slowed language development.

    As I accompanied her into the car, I felt desperate. Nothing was right with our world. She'd been born around the same time when the nation was witnessing the birth of another Great Recession. My job and my house had been victims. Then this happened. My child's language delay was identified, but doctors struggled to properly help her, I felt like we both needed to he rescued.

    I returned that afternoon as disenchanted with the little girl 1 loved as when 1 left. Walking slowly toward the school's playground gate, I found her preschool teacher racing to greet me.

    “You should have seen her today!” His breathy words were supported by excitement. I didn't interrupt. “See that climber.” He pointed to a wooden piece of playground equipment that looked like a rock wall. I nodded. “Well, every day since she started school, she's tried and failed to make it to the top.” He took a breath. “And today she did it!”

    He expressed his joy just as he'd witnessed her conquering Mount Everest! “She cheered and celebrated! I wish I'd recorded it!” His words comforted me. My daughter had conquered her mountain.

    As she ran toward me, I recognized something I hadn't before. I saw her perseverance(毅力). I saw her strength. I saw a Hero.

    GOING TO UNIVERSITY is supposed to be a mind-broadening experience. That statement is probably made in comparison to training for work straight after school, which might not be so encouraging. But is it actually true? Jessika Golle of the University of Tübingen, in Germany, thought she would try to find out. Her result, however, is not quite what might be expected. As she reports in Psychological Science this week, she found that those who have been to university do indeed seem to leave with broader and more inquiring minds than those who have spent their immediate post-school years in vocational (职业的) training for work. However, it was not the case that university broadened minds. Rather, work seemed to narrow them.

    Dr. Golle came to this conclusion after she and a team of colleagues studied the early careers of 2,095 German youngsters. The team used two standardized tests to assess their volunteers. One was of personality traits, including openness, conscientiousness（认真）and so on. The other was of attitudes, such as realistic, investigative and enterprising. They administered both tests twice—once towards the end of each volunteer's time at school, and then again six years later. Of the original group, 382 were on the intermediate track, from which there was a choice between the academic and vocational routes, and it was on these that the researchers focused. University beckoned for 212 of them. The remaining 170 chose vocational training and a job.

    When it came to the second round of tests, Dr. Golle found that the personalities of those who had gone to university had not changed significantly. Those who had undergone vocational training and then got jobs were not that much changed in personality, either—except in one crucial respect. They had become more conscientious.

    That sounds like a good thing, certainly compared with the common public image of undergraduates as a bunch of lazybones. But changes in attitude that the researchers recorded were rather worrying. In the university group, again, none were detectable. But those who had chosen the vocational route showed marked drops in interest in tasks that are investigative and enterprising in nature. And that might restrict their choice of careers.

    Some investigative and enterprising jobs, such as scientific research, are, indeed beyond the degreeless. But many, particularly in Germany, with its tradition of vocational training, are not. The researchers mention, for example, computer programmers and finance-sector workers as careers requiring these traits. If Dr. Golle is correct, and changes in attitude brought about by the very training Germany prides itself on are narrowing people's choices, that is indeed a matter worthy of serious consideration.

    Luke has always been my closest and constant companion these past five years. In fact, he is very friendly to me especially when I take care of other furry friends in our shelter.

    There have been a lot of forest fires during the summer season. Not far from our shelter, a forest caught fire during this hot summer. Luke rushed towards the forest where flames send out a terrible heat. There's no longer any hope at the moment to wait for Luke to come back to the shelter. In fact, I was waiting for the firemen to announce me his death in the forest. Suddenly, a fireman burst into my office and informed me that my dog Luke succeeded in saving four cats which were trapped by the flames. Luke seized the kittens, one by one moving them to a safe place.

    I immediately accompanied the fireman to the forest to pick up the rescued kittens, but Luke was not there. Then we heard the sound of a dog came from the forest barking furiously. The firemen followed the tracks of the dog until they found him barking loudly by the side of an injured fireman who was lying on the ground.

    That day, I was very proud of Luke for his two heroic actions. I paid a visit to the fireman accompanied with my adorable Luke. What a memorable scene when the fireman hugged Luke tightly to his chest! “One thousand thanks, Luke, for saving my life,” the fireman said.

    This true story of love shows us that pets are kind, loving, and caring. We should love and protect them. Don't belittle them. Little animals can make enormous things for humans.
