While it's wonderful to share a special trip with friends or family, traveling alone is another experience. {#blank#}1{#/blank#}

1）. Meet new people.

    People who are traveling alone seem more approachable to others. Before you know it, you could be chatting with some interesting folks at a sidewalk cafe or even joining a group of like-minded people on the beach. {#blank#}2{#/blank#}

2）.Do everything you want and nothing you don't want.

    Have you ever been hesitant to do that half-day at the spa you are eager for because you feel bad leaving your travel partner with nothing to do? {#blank#}3{#/blank#} If you want to “waste” the day sitting at an outdoor bar drinking a cocktail instead of sightseeing, you won't have to answer anyone.

3）.{#blank#}4{#/blank#}

    If traveling makes you a good, smart person, then traveling alone makes you better and smarter. Taking a trip by yourself might seem frightening. However, once you take the courage and get over your fears, you'll feel a sense of energy. A successful single vacation can inspire you to try new things in life.

Great service.

    By 2050, a completely new type of human evolve as a result of extremely new technology, behavior, and natural selection. This is according to Cadell Last, a researcher at the Global Brain Institute, who claims mankind is undergoing a major “evolutionary transition”.

    In less than four decades, Mr. Last claims we will live longer, have children in old age and rely on artificial intelligence to do ordinary and boring tasks. This shift is so significant, he claims, it is comparable to the change from monkeys to apes, and apes to humans. “Your 80 or 100 is going to be so radically different than your grandparents,” Mr. Last says, who believes we will spend much of our time living in virtual reality. Some evolutionary scientists believe this age could be as high as 120 by 2050.

    Mr. Last claims humans will also demonstrate delayed sexual maturation, according to a report by Christina Sterbenz in Business Insider. This refers to something known as life history theory which attempts to explain how natural selection shapes key events in a creature's life, such as reproduction. It suggests that as brain sizes increase, organisms need more energy and time to reach their full potential, and so reproduce less.

    Instead of living fast and dying younger, Mr. Last believes humans will live slow and die old. “Global society at the moment is a complete mess,” he told MailOnline. “But in crisis there is opportunity, and in apocalypse (启示) there can be transformation. So I think the next system humanity creates will be far more sophisticated, fair, and abundant than our current civilization.”

    “I think our next system will be as different from the modern world, as our contemporary world is from the medieval (中世纪的) world. The biological clock isn't going to be around forever,” he added, and said that people could pause it for some time using future technology.

    The change is already happening. Today, the average age at which a woman in Britain has her first baby has been rising steadily stands at 29. 8. In the US, just one percent of first children were born to women over the age of 35 in 1970. By 2012, that figure rose to 15 percent.

    “As countries become socio-economically advanced, more and more people, especially women have the option to engage in cultural reproduction,” Mr. Last added. And as well as having more child-free years to enjoy leisure time, he believes artificial intelligence will make up the need for low-skill jobs. We may also spend a large amount of time living in virtual reality. “I'm not quite sure most people have really absorbed the implications of this possibility,” Mr. Last said.

    His views are detailed in a paper, titled “Human Evolution, Life History Theory, and the End of Biological Reproduction" published Current Aging Science.

   The Healthy Habits Survey(调查)shows that only about one third of American seniors have correct habits. Here are some findings and expert advice.
1．How many times did you brush your teeth yesterday?
·Finding：A full 33% of seniors brush their teeth only once a day.
·Step：Remove the 300 types of bacteria in your mouth each morning with a battery－operated toothbrush. Brush gently for 2 minutes, at least twice a day.
2．How many times did you wash your hands or bathe yesterday?
·Finding：Seniors, on average, bathe fewer than 3 days a week. And nearly 30%wash their hands only 4 times a day—half of the number doctors recommend.
·Step：We touch our faces around 3,000 times a day－often inviting germs(病菌)to enter our mouth, nose, and eyes.Use toilet paper to avoid touching the door handle. And, most important, wash your hands often with hot running water and soap for 20 seconds.
3．How often do you think about fighting germs?
·Finding：Seniors are not fighting germs as well as they should.
·Step：Be aware of germs. Do you know it is not your toilet but your kitchen sponge(海绵)that can carry more germs than anything else? To kill these germs, keep your sponge in the microwave for 10 seconds.

    Whenever we turn on the TV or radio, read the newspapers, or surf the Internet, we'll be surrounded by the word “diet” everywhere. We have so easily been attracted by the promise of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically.

    It's obvious that diet products weaken us psychologically. They allow us to jump over the thinking stage that our weight problems lie not in actually losing the weight, but in controlling the consumption of fat. All we have to do is to swallow or recognize the word “diet” in food labels.

    What's more, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves that we don't have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.

    As a matter of fact, the danger that diet products bring not only lies in the psychological effects they have on us, but also in the physical harm they cause. Diet foods and diet pills contain zero calories only because the diet industry has created chemicals to produce these wonder products. And they can indirectly harm our bodies because taking them instead of healthy foods means we are stopping our bodies having basic nutrients. Diet products may not be nutritional, and the chemicals that go into diet products are potentially dangerous.

    Losing weight lies in the power of minds, not in the power of chemicals. Think twice before buying diet products. Once we realize this, we will be much better able to resist diet products, therefore, prevent the psychological and physical harm that comes from using them.

    For generations, cereal（麦片） has been the base of the American breakfast, but it now seems to be losing some of its advantages. Sales of breakfast cereal in the US are not so popular.

    The consumer's desire for a healthier way to start the day is now at its highest ever. Shoppers are seeking out “high protein(蛋白质) and fiber content and natural ingredients,” an expert said in a report. “Consumers today believe cereal is overly processed and doesn't contain enough nutrients.” That means cereal is facing the competition from fresh fruit, yogurt, breakfast bars and drinks, and even all-day breakfast meals at McDonald's or other fast-food chains.

    Consumers are increasingly seeking products that match their personal definition of real food, and that can mean foods that are less processed. Another big challenge for the industry is the ever-changing pattern of breakfast eaters, with an emphasis increasingly being placed on satisfying time-squeezed lifestyles. This desire for convenience seems to be especially increasingly being placed on satisfying time-squeezed lifestyles. This desire for convenience seems to be especially evident among young people who believe that cereal is inconvenient because it involves cleaning a dish afterward.

    Then there's the issue of price. Brand-name cereal prices jumped after the financial crisis in 2008, owing largely to the higher prices of grains and other ingredients. It's only in the last two years that prices have stabilized（稳定）.

    However, manufacturers and industry analysts say that if breakfast cereal makers can keep on adapting to consumers' changing needs, especially among young people, the business can grow again; besides, young people are still eating a lot of cereal, just not always for breakfast. Ready-to-eat cereal is in 90 percent of all households and nearly 94 percent of young households. For this group, cereal is more than just a breakfast item. It is also a popular snack option.

Being a superhero to others

    Ewan Drum has always liked superheroes. He likes how they help people. At age seven, he told his parents, “I want to dress up like a superhero and help the homeless.” {#blank#}1{#/blank#}Wearing his red superhero cape (斗篷), Ewan helped pass out 70 bag lunches to hungry people in a park in Detroit, Michigan. That's how Super Ewan was born.

    {#blank#}2{#/blank#}People donated(捐赠) money and supplies (供给物), and Ewan took them to those in need.

    When someone donated jugs(大罐) of water, Ewan and his family drove their car to get even more. They took the water to Flint, Michigan, a city that had unsafe drinking water. Another time, a businessman donated six turkeys(火鸡) for Thanksgiving. {#blank#}3{#/blank#}“In the end”, he says,“ we gave 64 turkey dinners to families all around Detroit.”

    Ewan has a motto: Everyone can be a superhero to someone. At an event called the Hero Round Table, Ewan told the audience, “It's not hard to help people. You can keep some socks and food in your car to help people in need. You can help a neighbor with doing the garden. {#blank#}4{#/blank#} ”

It's been several years since Super Ewan started his task. Every month, he still visits the same park to hand out clothes, food, and supplies to people who are hungry or homeless —his Super Friends. {#blank#}5{#/blank#}
