【推荐2】A growing number of Chinese young generations are looking for new methods to relieve (缓解) stress, which include raising unusual “pets”, hugging (拥抱) trees, watching stress relief videos and playing other stress-relieving toys.

A new toy called “mango dog” recently is becoming popular among young people.     1    . The process of making “mango dogs” allows them to free themselves from the anxieties of work and study. This is not the first time that young people have raised unusual “pets”. For example, college students have shared online their experiences of raising stones and paper box “dogs”. These “pets” share similar characteristics—they don’t cry, make noise or get sick.

    2    . “You may think you are hugging the tree, but in fact, the tree is hugging you,” says a young man. The same feeling is shared by those who have experienced tree hugging. They say that their anxiety has been relieved.     3    . In some big cities, some people have even organized tree hugging interest groups and regularly plan tree hugging activities.

The popularity of these stress relief methods reflects young people’s need to relieve emotional pressure. According to public data, there are more than 800 companies in China with names, businesses, products, or services with the term “stress relief”.     5    .

【推荐3】The Hadza hunter-gatherers of Tanzania live a life that has not changed much over ten thousand years. They have no crops, no house animals, no permanent shelters. In spite of long exposure to agriculturalist groups around them, the Hadza have maintained their lifestyle.

The story of the spread of agriculture is the story of growing population density (密度). Villages formed, then cities, then nations. Agriculture’s rise, however, came with a price. It introduced infectious diseases, social inequality, occasional famines (饥荒) and war. Professor Jared Diamond of UCLA (University of California, Los Angeles) has called the adoption of agriculture “the worst mistake in human history”— a mistake from which we have never recovered.

Looking at the Hadza, you can see why he came to this conclusion. They do not engage in warfare. They do not live densely (稠密地) enough to be threatened by an infectious outbreak. They have no known history of famine (饥荒). The Hadza diet is more stable (稳定 的) and varied than that of most of the world’s citizens. They live almost entirely free of possessions. They enjoy an extraordinary amount of leisure time, “working” — actively pursuing food — only four to six hours a day.

The chief reason the Hadza have been able to maintain their lifestyle so long is that their homeland is not an inviting place. Recently, however, population growth has brought a flood of people into Hadza lands. The region has generally been viewed by outsiders as unused, a Place in need of development. The Hadza, who by nature are not a combative (好战的) people, have almost always moved away instead of fighting.

There are many things to envy about the Hadza, mostly what free spirits they appear to be. Free from schedules, jobs, bosses, bills, traffic, taxes, laws, social duties and money. But who of us could live like them? It’s incredibly risky. Medical help is far away. One bad fall from a tree, one bite from a snake, and you’re dead. The fact is that it’s too late for us to go back to the Hadza lifestyle. Of greater concern is that soon it may be impossible for them to maintain theirs.

【推荐2】The season of ice cream treats is in full swing. Nothing captures pure joy and innocence like an ice cream cone (蛋筒) dripping down your hand.

But hove you ever wondered why some ice cream just stands apart from all the others? What really makes good ice cream? Well, here’s how to tell high-quality ice cream without even Lasting it.

Let the ingredients speak

High-quality ice cream is always made with real vanilla (香草) nuts, chocolate or fruit. On the other hand, if you’ve ever looked closely at the ingredients of ice cream from less fancy brands, you may have noticed that they only say “vanilla flavored”, or “chocolate flavored”. This is because they don’t contain real vanilla or chocolate.

Check the butterfat (乳脂) content

What differences do butterfat make? Besides making ice cream taste less like frozen milk, butterfat gives the product a creamy texture and a good flavor. In order to even be called ice cream in the United States, the product must contain at least 10 percent butterfat, according to the Food and Drug Administration’s regulations. High-quality brands of ice cream usually contain anywhere from 13 to 17 percent butterfat.

Take home the heavier one

Ice cream mixlure8 have air pumped into them as they freeze. Air is essential, or ice cream would be as hard as rock. The legal limit for the amount of air in the US is 100 percent. A more dense (浓的) ice cream will be creamier and will melt more slowly in the mouth.

But how can we tell which ice cream has less air in it? Well, one tiling you should know about ice cream is that it’s usually sold by volume, not by weight. The containers may be equal in size, but one ice cream may be denser than another and therefore weighs more.

【推荐3】Whether it’s curled up in the fetal position, flat on the stomach or stretched out across the bed, the way people sleep reveals their personality, a British sleep expert said.

Professor Chris Idzikowski, director of the Sleep Assessment and Advisory Service and a visiting professor at the University of Surrey in southern England, has identified five common sleep positions and what they mean.

Curled up in the fetal position is the most popular sleep pattern and favored by 51 percent of people, according to the results of the study he conducted for a large hotel group. Fetal sleepers tend to be shy and sensitive while people who assume the soldier position, flat on their back with arms at their sides, are quiet and reserved. Sleeping on one’s side with legs outstretched and arms down is called “log position” by Idzikowski, indicating a social, easy-going personality. The freefall, flat on the belly with the hands at the sides of the head, is the most unusual position. Only 6.5 percent of people prefer it and they are usually irritable, who are easy to be angered. Unassuming, good listeners usually adopt the starfish position — on the back with outstretched arms and legs.

Idzikowski, who identified the positions by comparing personality of people, their preferred way of sleeping and the most common positions,said once a sleeping style is adopted, it is rarely changed.
