    Do you look like your name? Scientists say there's a good chance you do.

This comes from a new study published in a magazine. Researchers from Israel found that our given names may have something to do with our facial (面部的) appearances.

    Lead writer Yonat Zwebner of a university, along with her team, did eight different experiments (实验) in Israel and France. The different experiments were set up to answer two main questions: whether people can correctly guess a person's name based only on a photo of a face and what is behind this matching effect.

    During the experiments, researchers asked students to look at photos of people's faces and guess each person's name from a list of four choices. They correctly guessed the right name 38 percent of the time, which was better than the 25 percent of a random (随机的) guess.

    What's more, when the faces the students looked at came from within their own country, they were able to best match the faces to the names. French students were better at matching only French names and faces while Israeli students were better at matching only Hebrew names and Israeli faces.

    Researchers believe it is possible that people change their appearances without paying attention to it, to match their names. One study especially backed up this idea, showing that a hairstyle, something that can be changed by people easily, was enough to guide others in correctly guessing their names.

    “Earlier research has shown there are cultural stereotypes (偏见) carried by names, including how someone should look. For example, people are more likely to imagine a person named Bob to have a rounder face than a person named Tim. We believe these stereotypes can, over time, influence people's facial appearances,” Zwebner said.

    The results of the experiments may even make parents think twice when choosing a name for their children.

    “If a name can influence appearance, it can influence many other things. This research opens an important direction that may suggest how parents should consider better the names for their children,” said Zwebner, who recently had a baby herself.

    “As parents, it was really difficult for us to name our 12-day-old daughter as we know the meanings of names.”

    Now many young people are traveling around the world on their own, not because they have no one to travel with, but because they prefer to go alone.

    Kristina Wegscheider from California first traveled alone when she was at college and believes that it is something everyone should do at least once in their life. “It opens up your mind to new things and pushes you out of your comfort zone.” Wegscheider has visited 46 countries covering all seven continents.

    In foreign countries, with no one to help you read a map, look after you if you get ill, or lend you money if your wallet is stolen, it is challenging. This is what drives young people to travel alone. It is seen as character building and a chance to prove that they can make it on their own.

    Chris Richardson decided to leave his sales job in Australia to go traveling last year. He set up a website, The Aussie Nomad, to document his adventures. He says he wished he had traveled alone earlier. “The people you meet, the places you visit, or the things you do, everything is up to you and it forces you to grow as a person,” said the 30-year-old man.

    Richardson describes traveling alone like “a shot in the arm”, which “makes you a more confident person that is ready to deal with anything”. He said, “The feeling of having overcome something on my own is a major part of what drives me each day when I'm dealing with a difficult task. I walk around with my head up because I know deep down inside that nothing is impossible if you try.”

    The great 19thcentury explorer John Muir once said, “Only by going alone in silence can one truly get into the heart of the wilderness.”
