What's your opinion on spicy food? Some people cannot handle even the smallest amount of chili(辣椒) in their dinner while others can't get enough of it.       

Scientists have long been puzzled by why some people love chili and others loathe it. Plenty of research has been done on the subject, dating back to as far as the 1970s. Previous results showed that a love of chili is related to childhood experiences, and cultural influences affect our taste buds, too. But the latest study has found that a person's love of spicy food may be linked to his or her personality more than anything else, CBC News reported.

“We have always assumed that liking drives intake—we eat what we like and we like what we eat. But no one has actually directly bothered to connect these personality traits with intake of chili peppers,” said Professor John Hayes from Pennsylvania State University, who led the study.

But before you look at the study, you should first know that “spicy” is not a taste, unlike sour, sweet, bitter and salty. It is, in fact, a burning sensation that you feel on the surface of your tongue. This got scientists thinking that maybe a love of spicy food is brought about by people's longing for thrill, something they usually get from watching action movies or riding a roller coaster.

In the study, 97 participants, both male and female, were asked to fill out questionnaires about certain traits of their personality, for example. Whether they like new experiences or tend to avoid risks. They were then given cups of water with capsaicin(辣椒素), the plant chemical that makes chili burn, mixed into them.

By comparing the answers to questionnaires and what participants said they felt about the spicy water. Researchers found that those who most tended to enjoy action movies or take risks were about six times more likely to enjoy the spicy water.

    Interestingly, we used to believe that the reason some people can withstand spicy food is that their tongue have become less sensitive to it. However, this latest study has found otherwise. It's not that it doesn't burn as badly, it's that you actually learn to like the burn,” Hayes explained.  

    Until late in the 20th century, most Americans spent time with people of generations. Now mid-aged Americans may not keep in touch with old people until they are old themselves. That's because we group people by age. We put our three-year-olds together in day-care center, our 13-year-olds in school and sports activities, and our 80-year-olds in senior-citizen homes. Why?

    We live away from the old for many reasons: young people sometimes avoid the old to get rid of fears for aging and dying. It is much harder to watch someone we love disappear before our eyes. Sometimes it's so hard that we stay away from the people who need us most.

    Fortunately, some of us have found our way to the old. And we have discovered that they often save the young.

    A reporter moved her family onto a block filled with old people. At first her children were disappointed. But the reporter baked banana bread for the neighbors and had her children deliver it and visit them. Soon the children had many new friends, with whom they shared food, stories and projects. “My children have never been less lonely,” the reporter said.

    The young, in turn, save the old. Once I was in a rest home when a visitor showed up with a baby. She was immediately surrounded. People who hadn't gotten out of bed in a week suddenly were ringing for a wheelchair. Even those who had seemed asleep wake up to watch the child. Babies have an astonishing power to comfort and cure.

    Grandparents are a special case. They give grandchildren a feeling of security and continuity. As my husband put it, “my grandparents gave me a deep sense that things would turn out right in the end.”

    Grandchildren speak of attention they don't get from worried parents. “My parents were always telling me to hurry up, and my grandparents told me to slow down,” one friend said. A teacher told me she can tell which pupils have relationships with grandparents: they are quieter, calmer, more trusting.

    Since my family were not going to be helpful about my taking a cooking job, I decided I would look for one all by myself and not to tell them about it till I'd got a permanent one.

    I had seen an agency advertised in a local paper, so as soon as there was no one about to say “Where are you going?” I rushed out of the house in search of it. I was wildly excited, and as nervous as if I were going on the stage. Finding the place quite easily, I tore up three flights of stairs, and swung breathlessly through a door which said “Enter without knocking, if you please.”

    The simple atmosphere of the office calmed me, and I sat down on the edge of a chair. The woman at the desk opposite looked carefully at me. Then she questioned me in a low voice. I answered softly and started to feel helpless. She wondered why I was looking for this sort of job, so I felt I had to give her the idea of a widowed mother struggling against poverty. But I felt more helpless when she told me that it would be difficult to get a job without experience or references. Suddenly, the telephone on her desk rang. While having a mysterious conversation, she kept looking at me. Then I heard her say:

    “In fact, I've got someone here who might suit.” She wrote down a number, and my spirits rose as she held out the paper to me, saying: “Ring up this lady. She wants a cook immediately. Cook a dinner for ten people tomorrow. Could you manage that, I wonder?”

    “Oh, yes,” say I—never having cooked for more than four. Then I rushed out and called the lady, Miss Cathy. I said confidently that I was just what she was looking for. “Are you sure?” she kept saying. Anyway she decided to employ me and a permanent position if I carried out the promise of my self-praise. I asked her what tomorrow's menu was to be.

    “Just a small, simple dinner: lobster cocktail, soup, turbot mornay, fruit salad and a savory.” In a rather shaken voice I promised to turn up in good time tomorrow and rang off.

    You often can choose a private setting when you browse(浏览) the internet. But be forewarned: It may not afford nearly as much privacy as you expect. That's the finding of a new study.

    Major web browsers, such as Google's Chrome and Apple's Safari, often a private-browsing option. It's sometimes referred to as “incognito.” This option lets you surf the Internet browser and saves a record into its history of each page that you visited. And what sites you visit won't affect the suggestions your browser makes the next time you're filling out an online form.

Many people believe—incorrectly— that the incognito setting protects them more broadly. Most believe it even after reading a web browser's explanation of the incognito mode.

    For instance, a new study had 460 people read web browsers' descriptions of private browsing. Each person read one of 13 descriptions. Then the participants answered questions about how private they thought their browsing would be while using this tool. The volunteers didn't understand the incognito mode. This was true no matter which browser explanation they had read. The researchers reported their findings on April 26 at the 2018 World Wide Web Conference in Lyon, France.

    More than half of the volunteers thought that if they logged into a Google account through a private window, Google wouldn't keep a record of their search history. Not true. And about one in every four participants thought private browsing hid their device's IP address. That's wrong, too.

    Blase Ur was one of the study's authors. He's an expert in computer security and privacy in Illinois at the University of Chicago. Companies could clear up this confusion by giving better explanations of the incognito mode, his team says. For example, the browsers should avoid vague（模糊).The web browser Opera, for instance, promises users that “your secrets are safe.” Nope Firefox encourages users to “browse like no one's watching.” In fact, someone might be.

    Alabama: Priester's Pecans

    Dessert in the South basically starts and ends with an ooey­gooey pecan (核桃) pie. Especially in Alabama, where the pecan is the official state nut. While there are plenty of farms that pick and package pecans, perhaps the most famous is Priester's, a family­run business that's been supplying Alabama with its favorite nuts for over seven decades.

    Alaska: Salmon jerky

    Forget beef jerky (肉干) ­ in Alaska, it's all about the salmon jerky. Home to five different species of the flavorful fish (king, red, pink, silver, and chum), the northernmost state produces nearly one­third of the wild salmon consumed around the world. Bonus: Salmon is one of the seven healthiest fish you can eat.

    Arizona: Saguaro cactus

    The largest cactus (仙人掌) in the United States, the saguaro cactus is found only in Arizona's Sonoran Desert. Living to be up to 200 years old, the cacti, whose flower is also the state's flower, are generally around 30 feet tall and can grow unlimited arms. Want to see for yourself? Visit one of these 10 outstanding desert escapes in America.

    California: Wine Guide

    It isn't called "Wine Country" for no reason. Northern California, specifically Napa Valley and Sonoma Valley, produce over 60,000 registered wine labels, making vino (酒类产品) the state's most valuable agricultural product. If you're looking for the most popular varietals (优质酿酒葡萄汁), the top two frequently planted grapes are chardonnay and cabernet sauvignon.
