Higher income has already been linked to greater longevity and better health.A new study by a famous researcher suggests geographic location plays an key role in life expectancy(预期)for lower earners.That means if you're poor,you're likely to live for longer in a city like San Francisco or New York than in a city like Detroit or Cincinnati.

Being rich anywhere broadly means enjoying good health anywhere,but location is a key factor in health for people in lower income groups.Michael Stepner,one of the study's co-authors,said economic decline and decreasing populations in the Rust Belt aren't necessarily to blame.

The study found that location matters for low earners.Low-income individuals tend to live more healthily and for longer in cities with college-educated populations,high incomes,more immigrants,and high levels of government expenses,such as New York and San Francisco.The study also found measures of health—insurance coverage and health spending were of lesser importance than social and economic factors in determining health for low-income individuals.Nor did having health insurance seem to be a factor in increasing life expectancy for poorer groups."The key driver of differences in inequality across areas of life expectancy is probably not access to health care,"Mr Stepner said.

While I was teaching in China, I became interested in acupuncture(针灸). It was after returning from China and witnessing how successful it had been that I reached the decision to become an acupuncturist myself. I was lucky to discover that the town where I lived had a famous college of traditional acupuncture.

Alternative medicine such as acupuncture is particularly important for me because I firmly believe that it works on the level of body, mind and spirit. This is very different from Western medicine which is supposed to work only on the body. When a person is ill, it is believed that there’s something in their life that is putting their energy levels out of balance. What alternative therapies(疗法)try do to is kelp to gradually push that energy back into balance. The result is that any disease present might naturally disappear as it cannot survive when energies are balanced.

I’ve treated a wide range of people for various conditions, for example people suffering from stress and anxiety. To acquire a qualification in acupuncture, I took a course that lasted three years. I had to go to the college about one weekend in three. I also had a large amount of homework and practical work to do, which I did two or three evenings a week. This involved locating pints on different people. As you can imagine, this isn’t straightforward as people are of different sizes and have differently shaped bodies.

In the future I hope to set up an alternative health clinic which will involve myself as an acupuncturist but perhaps other people as well. I’d like to work with people who provide treatments such as rubbing(按摩)and pressing people’s feet in a special way to help them relax and feel well. I’d like to set it up somewhere in the countryside, where people could feel free from the stress of life.

Where do dogs come from?

Gray wolves are their ancestors. Scientists are pretty consistent about that. And researchers have suggested that dogs’ origins can date back to Europe, the Near East, Siberia and South China. Central Asia is the newest and best candidate, according to a large study of dogs from around the world.

Laura M. Shannon and Adam R. Boyko at Cornell University, and an international group of other scientists, studied not only purebred(纯种的) dogs, but also street or village dogs.

Dr. Shannon analyzed three different kinds of DNA, Dr. Boyko said, the first time this has been done for such a large and diverse group of dogs from 38 countries. And that led them to Central Asia as the place of origin for dogs in much the same way that genetic studies have located the origin of modern humans in East Africa.

The analysis, Dr. Boyko said, pointed to Central Asia, as the place where "all the dogs alive today" come from. The data did not allow precise dating of the origin, he said, but showed it occurred at least 15,000 years ago.

Greger Larson of Oxford University, who is leading a large international effort to analyze ancient DNA from fossilized bones, said he was impressed by the study. "It’s really great to see not just the number of street dogs, but also the geographic breadth and the number of remote locations where the dogs were sampled," he said in an email. He also praised the sampling of different kinds of DNA and the analytic methods.

Dr. Larson, who was not involved with the study, said he thought the Central Asia finding required further testing. He said he suspected that the origins of modern dogs were "extremely messy" and that no amount of sampling of living populations will be definitive. He said a combination of studies of modern and ancient DNA is necessary.
