I first came across the concept of pay-what-you-can cafes last summer in Boone, N.C., where I ate at F.A.R.M (Feed All Regardless of Means) Café. You can volunteer to earn your meal, pay the suggested price($10) or less, or you can overpay—paying it forward for a future customer's meal. My only regret after eating there was not having a chance to give my time. So as soon as Healthy World Café opened in York in April, I signed up for a volunteer shift(轮班).

    F.A.R.M and Healthy World are part of a growing trend of community cafés. In 2003, Denise Cerreta opened the first in Salt Lake City. Cerreta now runs the One World Everybody Eats Foundation, helping others copy her pay-what-you can model.

    “I think the community café is truly a hand up, not a handout,” Cerreta said. She acknowledged that soup kitchens(施粥所) have a place in society, but people typically don't feel good about going there.

    “One of the values of the community café is that we have another approach,” she said. “Everyone eats here, no one needs to know whether you volunteered, overpaid or underpaid.”

    The successful cafés not only address hunger and food insecurity but also become necessary parts of their neighborhood – whether it's a place to learn skills or hear live music. Some teach cooking to seniors; some offer free used books. Eating or working there is a reminder that we are all in this world together.

    My 10 am—1pm shift at World-Healthy-Café began with the café manager — one of the two paid staff members. Our volunteer crew wasn't the most orderly, but we managed to prepare and serve meals with a lot of laughs in between. At the end of my shift, I ordered my earned meal at the counter, together with other volunteers. After lunch, I walked out the door, with a handful of new friends, music in my head and a satisfied belly and heart.

The World's Coolest Places

    There's nothing wrong with a relaxing week at the beach. But travel can also be an education, a step toward empathy(共鸣) and international understanding, so for those longing to escape the crowds this summer, encounter new worlds and return with a tale, here're a few little-known travel destinations I recommend.

    After spending a year in Brazil on a student exchange program, her mother recalled(回忆), Marie Colvin returned home to find that her classmates had narrowed down their college choices. “Everyone else was already admitted to college,” her mother, Rosemarie Colvin, said from the family home. “So she took our car and drove up to Yale and said, 'You have to let me in .' ”

    “Impressed--she was a National Merit (全国英才) finalist who had picked up Portuguese in Brazil. Yale did, admitting her to the class of 1978, where she started writing for the Yale Daily News and decided to be a journalist,” her mother said.

    On Wednesday, Marie Colvin, 56, an experienced journalist for The Sunday Times of London, was killed as Syrian forces shelled(炮击) the city of Homs. She was working in a temporary media center that was destroyed in the attack.

    “She was supposed to leave Syria on Wednesday”, Mrs. Colvin said. “Her editor told me he called her yesterday and said it was getting too dangerous and they wanted to take her out. She said she was doing a story and she wanted to finish it.”

    Mrs. Colvin said it was pointless to try to prevent her daughter from going to conflict （冲突）zones. “If you knew my daughter,” she said, “it would have been such a waste of words. She was determined, she was enthusiastic about what she did, it was her life. There was no saying 'Don't do this.' This is who she was, absolutely who she was and what she believed in: cover the story, not just have pictures of it, but bring it to life in the deepest way you could.” “So it was not a surprise when she took an interest in journalism,” her mother said.

    Kincaid looked at his watch: eight-seventeen. The truck started on the second try, and he backed out, shifted gears, and moved slowly down the alley under hazy sun. Through the streets of Bellingham he went, heading south on Washington 11, running along the coast of Puget Sound for a few miles, then following the highway as it swung east a little before meeting U.S Route 20.

    Turning into the sun, he began the long, winding drive through the Cascades. He liked this country and felt unpressed stopping now and then to make notes about interesting possibilities for future expeditions or to shoot what he called "memory snapshots." The purpose of these causal photographs was to remind him of places he might want to visit again and approach more seriously. In later afternoon he turned north at Spokane, picking up U.S. Route 2, which would take him halfway across the northern United States to Duluth, Minnesota.

    He wished for the thousandth time in his life that he had a dog, a golden retriever, maybe, for travels like this and to keep him company at home. But he was frequently away; overseas much of the time and it would not be fair to the animal. Still, he thought about it anyway. In a few years he would be getting too old for the hard fieldwork. "I must get a dog then." He said to himself.

    Drives like this always put him into a sentimental mood. The dog was part of it. Robert Kincaid was alone as it's possible to be—an only child, parents both dead, distant relatives who had lost track of him and he of them, no close friends.

    He thought about Marian. She had left him nine years ago after five years of marriage. He was fifty-two now, that would make her just under forty. Marian had dreams of becoming a musician, a folksinger. She knew all of the Weavers' songs and sang them pretty well in the coffeehouse of Seattle. When he was home in the old days, he drove her to the shows and sat in the audience while she sang.

    His long absences—two or three months sometimes—were hard on the marriage. He knew that. She was aware of what he did when they decided to get married, and both of them had a vague sense that it could all be handled somehow. It couldn't when he came from photographing a story in Iceland and she was gone. The note read, "Robert, it didn't work out. I left you the Harmony guitar. Stay in touch."

    He didn't stay in touch. Neither did she. He signed the divorce papers when they arrived a year later and caught a plane for Australia the next day. She had asked for nothing except her freedom.

    Tiredness, coughing, a runny nose and a sore throat—among all sicknesses there is probably none more common than the flu (流感), which we all get now and then. However, bird flu is a completely different story.

    In 2003, the H5N1 bird flu swept across 15 countries, including China, with sufferers reporting chest pain, difficulty breathing, fever and severe coughing. More than 600 people were infected, and about 60 percent died. Now, another type of bird flu hit Shanghai and three neighboring provinces, and this time the virus is called H7N9. By the afternoon of April 11, the new virus had taken nine lives out of 35 infected, according to Xinhua News Agency.

    The "H" and "N" in the virus' name refer to two kinds of proteins (蛋白质) on the surface of the virus. Any change of the numbers of the two proteins indicates a new mutation(变异). Most of the mutations only affect birds, such as chickens and pigeons, and don't normally spread to humans. But once they do, the results can be disastrous.

    "Any time an animal influenza virus crosses to humans, it is a cause for concern, " Malik Peiris, virologist (病毒学家) at the University of Hong Kong, told Nature magazine. Take the SARS epidemic (传染病) in 2003 as an example. The virus behind the disease is thought to have jumped to humans from animals. The virus was a complete "stranger" to human bodies, which hadn't developed an immunity (免疫力) against it.

    But there is something more about the new H7N9 bird flu. Unlike the H5N1 bird flu, which causes severe sickness in birds, the H7N9 has been evolving under the radar(悄悄地) since it travels between birds without causing noticeable illness. That makes it difficult to keep track of the disease.

    The good news is that there's so far no sign that the virus is spreading from person to person. But since there is no vaccine (疫苗) for the disease yet, the World Health Organization recommends that you wash your hands after meeting with sick people and before and after you eat or prepare food, and they also suggest avoiding contact with birds or their eggs.
