Researchers claimed that waitresses who wear red get up to 26 percent extra in tips than they would wearing other colors. However, the team finds that the sexes tip very differently—with the bigger tips coming only from male customers.
No matter what color they wear, female diners will give the same kind of amounts for service every time. Yet men, whether they realize it or not, add anything between 15 and 26 percent more to a waitress in red than they would if it was the same waitress wearing a different color.
The test was simple. Take 11 waitresses in five restaurants over a six-week period and ask them to wear the same kind of T-shirt every day but change the colors. Previous research has suggested waitresses could earn more if they acted charmingly or wore more make-up than their colleagues. But this study, by the Journal of Hospitality and Tourism Research, only changed the color of the T-shirt. Every other aspect from make-up to behavior remained the same.
When wearing either black, white, green, blue or yellow T-shirts, the size of the tips from both male and female customers was almost identical. But when they wore red, the size of the tips went up by between 15 and 26 percent from male customers, yet stayed the same from female ones.
A total of 272 restaurant customers were studied by researchers Nicolas Gueguen and Celine Jacob for the international journal of the tourism industry.
Even as a T-shirt, it shows just how much the color red is thought, by men, to increase the physical and sexual attractiveness of woman, said the researchers.
The researchers wrote: As red color has no negative effect on women customers, it could be in their interest to wear clothes at work.

Like many languages spoken by people, Ayapaneco is dying. Only two people in the world still speak it, and they won't talk to each other.
Spoken in Mexico for centuries, Ayapaneco is one of 68 surviving languages in the mainly Spanish-speaking nation. The two speakers are Manuel Segovia and Isidro Velazquez. Though they live only 500 meters from each other in the village, the two men seldom talk to each other. Daniel, an American expert, who is working to make a dictionary of Ayapaneco, says the two men “don’t have a lot in common,” and that Segovia can be “active” while Velasquez tends to mind his own business and stay at home.
While Segovia still speaks to his wife and son in Ayapaneco, neither of them can manage more than a few words. Velasquez hardly speaks his native tongue any more. Daniel is working to preserve the language in dictionary form before its last surviving speakers pass away. According to Daniel, Ayapaneco and the other languages began dying out with the introduction of public Spanish education in the mid-20^th century. For decades, local children weren’t allowed to speak anything else. Many people to cities, starting in the 1970s, also helped the dying out of native languages.
Ayapaneco is the name given to the language; Segovia and Velazquez call it “Nuumte Oote”, which means “true voice”. Neither man, however, speaks the same language. The dictionary will contain two versions(版本) of the language when it comes out later this year. Those behind the dictionary aren’t the only ones trying to save Ayapaneco. The National Language Institute plans to hold classes so that Segovia and Velasquez can pass on what they know to children.
It is thought that there are about 6,000 languages spoken on earth and that about half will disappear over the next 100 years. Let’s hope the “true voice” isn’t one of them.

One day, a poor boy who was trying to pay his way through school by selling goods from door to door found that he had only one dime left. He was hungry so he decided to beg for a meal at the next house.
However, he became nervous when a lovely young woman opened the door. Instead of a meal, he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?”
“You don’t owe me anything,” she replied, “Mother has taught me never to accept pay for a kindness.” He said, “Then I thank you from the bottom of my heart.” As Haward Kelly left that house, he not only felt stronger physically, but it also increased his faith in God and the human race. He was about to give up and quit before this point.
Years later, the young woman became seriously ill. The local doctors were baffled. They finally sent her to the big city, where specialists could be called in to study her rare disease. Dr. Haward Kelly, now famous was called in for the consultation. When he heard the name of the town she came from, a strange light filled his eyes. Immediately, he rose and went down through the hospital hall into her room.
Dressed in his doctor’s gown he went in to see her. He recognized her at once. He went back to the consultation room and determined to do his best to save her life. From that day, he gave special attention to her case.
After a long struggle, the battle was won. Dr. Kelly requested the business office to pass the bill to him for approval. He looked at it and then wrote something on the side. The bill was sent to her room. She was afraid to open it because she was positive that it would take the rest of her life to pay it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words,
“Paid in full with one glass of milk.”
(Signed) Dr. Haward Kelly
Tears of joy flooded her eyes as she prayed silently, “Thank You, God. Your love has spread through human hearts and hands.”

When I was growing up in the suburbs of New York, our first local Earth Day was organized around a drive to a town field where families were urged to empty items from their basements （地下室）for recycling rather than dropping them in the dustbin. It was an eye opening idea for a kid in 1970.
But as an environmental reporter, I'm bored of the large amount of deals and promotions that arrive by email or in my office or home mailbox on Earth Day. Like Valentine's Day, Earth Day has become a huge marketing opportunity—a way to promote consumption.
In fact, Earth Day is such a good sales opportunity that some shops, like Target, have expanded Earth Day into Earth Month.
There isn't time to give you a variety of the Earth Day shopping opportunities I was informed of this past week. They included deals on buying bottled water and earth-friendly wipes.
My award for the silliest promotion: a plan to gift 25 of the most environmentally conscious stars with unique, useful and “green” products and services, including skin care products, cheese-cake and artwork. My guess is most of the stuff will end up in celebrities' garbage.
Is buying and selling a good way to celebrate and protect the environment? I would argue that Earth Day might be an occasion to consider giving up purchases or habits that are environmentally questionable or that we could happily do without. How about not buying bottled water, but refilling a water bottle? How about not buying foods—even “organic” foods—that are packed in non-recyclable plastic?
Don't get me wrong. The company of Bridgestone is celebrating Earth Day by promising to repurpose a spent tire（利用废旧轮胎）for every tire that it sells. Verizon will plant a tree for each cell phone you trade in. Some coffee stores will even refill reusable cups at no charge. Target is giving out free reusable carrier bags without requiring a purchase.
But few shopkeepers are taking the next step－charging a fee at the cash register for disposable plastic bags, a common practice in Europe－to encourage customers to use those new reusable carriers.
Earth Day is transient（短暂的）. If you only showed love on Valentine's Day, would that really mean anything at all?

“If you have not played video games, your childhood should be called 'incomplete'.” That's from Zhan Zaozao, 29, the screenwriter（编剧）of Play to Grow Up, a 40-minute short movie.
It tells the story of two men growing up fans of video games and how they find happiness in games. While people think playing games makes one lazy and is a waste of time, Zhan tries to prove that one can make a living out of it. In the movie, the two heroes, Dunzi and Yanjing, who are in middle school, visit a video games room on the street each day after school.
But why make a short movie about video games, since there are lots to write about childhood, such as puppy love, sports and study? “Playing games is so important to everyone's childhood from little kids to teenagers, though it's a bittersweet experience,” said Zhan.

Many consider playing games as a bad influence, but it isn't all true, according to Zhan. “It can change your attitude toward life,” said Zhan. “On the other hand, the movie also tells you that, although the world of video games is fun, you must face real life at the end of the day. ”
