    Sleep, as we know, is important to us because it helps restore tired organs and tissues in our body. But how much sleep do we actually need?

{#blank#}2{#/blank#}

    For most of us, eight hours seems to be about the right amount. Yet we know that there are a great many people who get along perfectly with less sleep and some who may even need more. A great deal depends on the way we live. But a good general rule to follow is to sleep as long as we have to in order to feel happy and be able to work at our best when we are awake.

    There are actually different levels of sleep. There is a deep sleep and a shallow sleep. In a shallow sleep our body does not get the same kind of rest as it gets in a deep sleep, so that after eight hours of a shallow sleep we may still feel tired. But a short deep sleep can be very restful.

    Alexander the Great was able to get a deep sleep whenever he needed it. Once, during the night before an important battle, he remained awake longer than anyone else. Then he wrapped himself in a cloak and lay down on the earth. He slept so deeply that his generals had to wake him three times to give command to attack!

    Normally when we go to sleep, our “ sleep center” blocks off nerves so that both our brain and our body go to sleep. One prevents us form wanting to do anything and the other makes our internal organs and limbs go to sleep. But someone will fall asleep (brain sleep) and keep on marching, because his body is not asleep!

    Men are spending more and more time in the kitchen encouraged by celebrity (名人) chefs like Gordon Ramsay and Jamie Oliver, according to a report from Oxford University.

    The effect of the celebrity role models, who have given cooking a more manly picture, has combined with a more general drive towards sexual equality and men now spend more than twice the amount of time preparing meals than they did in 1961.

    According to the research by Prof. Jonatahn Gershuny, who runs the Centre for Time Research at Oxford, men now spend more than half an hour a day cooking, up from just 12 minutes a day in 1961.

    Prof. Gershuny said, “The man in the kitchen is part of a much wider social trend. There has been 40 years of sexual equality, but there is another 40 years probably to come.”

    Women, who a generation ago spent nearly two hours a day cooking, now spend just one hour and seven minutes—a great fall, but they still spend far more time in the kitchen than men.

    Some experts have named these men in aprons as “Gastrosexuals (men using cooking skills to impress friends)”, who have been inspired to pick up a kitchen knife by the success of Ramsay, Oliver as well as other male celebrity chefs such as Hugh Fearnley-Whittingstall, Marco Pierre White and Keith Floyd.

     “I was married in 1974. When my father came to visit me a few weeks later, I was wearing an apron when I opened the door. He laughed,” said Prof. Gershuny. “That would never happen now.”

    Two-thirds of adults say that they come together to share at least three times a week, even if it is not necessarily around a kitchen or dining room table. Prof. Gershuny pointed out that the family meal was now rarely eaten by all of its members around a table—with many “family meals” in fact taken on the sofa in the sitting room, and shared by family members. “The family meal has changed a lot, and few of us eat—as I did when I was a child—at least two meals a day together as a family. But it has survived in a different format.”

    Cold weather has a great effect on how our minds and our bodies work. Maybe that is why there are so many expressions that use the word cold. For centuries, the body's blood has been linked closely with the emotions. People who show no human emotions or feelings, for example, are said to be cold –blooded. Cold –blooded people act in merciless ways. They may do cruel things to others, and not by accident. For example, a newspaper says the police are searching for a cold-blooded killer. The killer murdered someone, not in self-defense. He seemed to kill with no emotion.

    Cold can affect other parts of the body, the feet, for example. Heavy socks can warm your feet, if your feet are really cold. But there is an expression—to get cold feet –that has nothing to do with cold or your feet. The expression means being afraid to do something you had decided to do. For example, you agree to be president of an organization. But then you learn that all the other officers have given up the position. All the work of the organization will be your responsibility. You are likely to get cold feet about being president when you understand the situation.

    Cold can also affect your shoulder. You give someone the cold shoulder when you refuse to speak to them. You treat them in a distant, cold way. The expression probably comes from the physical act of turning your back toward someone, instead of speaking to him face-to-face. You may give a cold shoulder to a friend who has not kept a promise he made to you. Or, to someone who has lied about you to others.

    A cold fish is not a fish. It is a person. But it is a person who is unfriendly, unemotional and shows no love or warmth. A cold fish does not offer much of himself to anyone.

    Out in the cold is an expression often heard. It means not getting something that everybody else got. A person might say that everybody but him got a pay raise. He was left out in the cold. And it is not a pleasant place to be.

    Frank Woolworth was born in Rodman, New York, in 1852. His family were very poor farmers, and there was never enough to eat. Frank decided he did not want to be a farmer. He took a short business course, and went to work as a salesman in a large city.

    Woolworth realized he had a natural skill for showing goods to attract people's interest, but he soon learned something more important. One day his boss told him to sell some odds and ends (小商品) for as much as he could get. Frank put all these things on one table with a sign which said FIVE CENTS EACH. People fought and pushed to buy the things and the table was soon cleared.

    Soon afterwards, Woolworth opened his own store, selling goods at five and ten cents. But he had another lesson to learn before he became successful. That is, if you want to make money by selling low-price goods, you have to buy them in large quantities directly from the factories. Once, for example, Woolworth went to Germany and placed an order for knives. The order was so large that the factory had to keep running 24 hours a day for a whole year. In this way, the price of the knives was cut down by half.

    By 1919, Woolworth had over 1000 stores in the US and Canada, and opened his first store in London. He made many millions and his name became famous throughout the world. He always run his business according to strict rules, of which the most important was: “ THE CUSTOMER IS ALWAYS RIGHT.”

Earlier this year Rodney Smith Jr. made headlines when he drove eight hours from his home in Huntsville. Alabama, to cut the lawn for an elderly soldier in North Carolina who couldn't find anyone to help him with his yard work.

That wasn't the first time the twenty-nine-year-old Bermuda native had gained such attention. To do his good deeds, Rodney often finds leads for those in need through social media.

Back to one August afternoon in 2015, Rodney Smith Jr. was driving home. That's when Rodney saw an elderly man struggling to mow his lawn. He would take a couple of shaky steps, using the handle to stabilize himself, pause, then slowly push the mower again. Rodney decided to help. Mr. Brown thanked him greatly, and Rodney went home feeling satisfied.

Sitting at his computer to do his homework, Rodney couldn't get Mr. Brown out of his mind. There must be many Mr. Browns out there. He went online and posted that he would mow lawns for free for senior citizens. Messages flooded in.

One day a cancer-battling woman said she wasn't having a good day. Rodney decided to do more than mowing lawns. After he finished mowing, he knocked on her door. "You're going to win this fight, Madam", he said. Then he asked folks to pray for her on social media.

Word of Rodney's mission spread. A grandmother in Ohio said he'd encouraged her 12-year-old grandson to mow lawns. He got a letter from a seven-year-old boy in Kansas. "Mr. Rodney, I would like to be a part of your program, and I'll make you proud," he wrote.

That gave Rodney an idea. In 2017, he decided to establish a programme Raising Men Lawn Care Service to make a national movement for young people. The kids learn the joy of giving back.

Yard work seems like a small, simple thing, but taking care of the lawn means a lot to the people they do it for. "When we mow their yards for free, they can use the money for healthcare and food etc. It means more than you would think," Rodney said.
