Here is how your health risks increase at different BMIs(体重指数) if your waist circumference（腰围）is higher than 40 inches（102 cm） in men and 35 inches （88 cm） in women:
☆If your BMI is in the 18.5 to 24.9 range, or “Normal”, then a larger waist that is near or greater than 40 inches for men and 35 inches for women can indicate that you are at “increased” risk.
☆If your BMI is in the 25 to 29.9 range, or “Overweight”, then a larger waist (less than or equal to 40 inches for men and 35 inches for women) can indicate that you are at “increased” risk. Above these sizes, the risk is considered “high”.
☆If your BMI is in the 30 to 34.9 range, or “Obese I”, then a larger waist (less than or equal to 40 inches for men and 35 inches for women) can indicate that you are at “high” risk. Above these sizes, the risk is considered “very high.”
☆If your BMI is in the 35 to 39.9 range, or “Obese II”, then a larger waist (less than or equal to 40 inches for men and 35 inches for women) can indicate that you are at “very high” risk. Above these sizes, the risk is still considered “very high”.
☆If your BMI is or in the 40 + range, or “Obese III”, then a larger waist (less than or equal to 40 inches for men and 35 inches for women) can indicate that you are at “extremely high” risk. Above these sizes, the risk is still considered “extremely high”.

If you were to walk up to Arthur Bonner and say, “ Hey, Butterfly Man,” his face would break into a smile. The title suits him. And he loves it.
Arthur Bonner works with the Palos Verdes blue butterfly, once thought to have died out. Today the butterfly is coming back — thanks to him. But years ago if you’d told him this was what he’d be doing someday, he would have laughed, “ You’re crazy.” As a boy, he used to be “ a little tough guy on the streets”. At age thirteen, he was caught by police stealing. At eighteen, he landed in prison for shooting a man.
“ I knew it had hurt my mom,” Bonner said after he got out of prison. “So I told myself I would not put my mom through that pain again.”
One day he met Professor Mattoni, who was working to rebuild the habitat for an endangered butterfly called El Segundo blue.
“I saw the sign ‘Butterfly Habitat’ and asked, ‘How can you have a habitat when the butterflies can just fly away?’” Bonner recalls. “Dr. Mattoni laughed and handed me a magnifying glass(放大镜) , ‘Look at the leaves.’ I could see all these caterpillars(蝴蝶的幼虫) on the plant. Dr Mattoni explained, ‘Without the plant, there are no butterflies.’”
Weeks later, Bonner received a call from Dr. Mattoni, who told him there was a butterfly needed help. That was how he met the Palos Verdes blue. Since then he’s been working for four years to help bring the butterfly back. He grows astragalus, the only plant the butterfly eats. He collects butterflies and brings them into a lab to lay eggs. Then he puts new butterflies into the habitat.
The butterfly’s population, once almost zero, is now up to 900. For their work, Bonner and Dr. Mattoni received lots of awards. But for Bonner, he earned something more: he turned his life around
For six years now Bonner has kept his promise to stay out of prison. While he’s bringing back the Palos Verdes blue, the butterfly has helped bring him back, too.

What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology(生物技术). With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today’s leading killers, such as heart disease, cancer, and aging itself, will become distant memories.
In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond l20 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs. The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on—in much the same way our bodies make new skin cells to take the place of old ones.
It is exciting to imaging that the advance in technology may be changing the most basic condition of human existence, but many technical problems still must be cleared up on the way to this wonderful future.

Jim suffered heart problems. In conversation he expressed little joy and it seemed that his life was drawing to a close.
When his heart problems led to operation, Jim went through it successfully, and a full recovery was expected. Within days, however, his heart was not beating properly. Jim was rushed back to operation, but nothing was found to explain the cause of his illness. He died on the operating table on the day before his 48th birthday
Dr. Bruce Smoller, a psychologist, had had many conversations with him, and the more he learned, the stranger he realized Jim's case was. When Jim was a child, his father, a teacher, suffered a heart attack and stayed home to recover. One morning Jim asked his father to look over his homework, promising to come home from school at noon to pick it up. His father agreed, but when Jim returned his father had died. Jim's father was 48.
“I think all his life Jim believed he killed his father,” Dr. Smoller says. “He felt that if he had not asked him to look at his homework, his father would have lived. Jim had been troubled by the idea. The operation was the trial he had expected for forty years. “ Smoller believes that Jim willed himself not to live to the age of 48.
Jim's case shows the powerful role that attitude plays in physical health, and that childhood experiences produce far-reaching effect on the health of grown-ups. Although most cases are less direct than Jim's, studies show that childhood events, besides genes, may well cause such midlife diseases as cancer, heart disease and mental illness.

The traditional tent cities at festivals such as Glastonbury may never be the same again. In a victory of green business that is certain to appeal to environmentally-aware music-lovers, a design student is to receive financial support to produce eco-friendly tents made of cardboard that can be recycled after the bands and the crowds have gone home.
Major festivals such as Glastonbury throw away some 10,000 abandoned tents at the end of events each year. For his final year project at the University of the West of England, James Dunlop came up with a material that can be recycled. And to cope with the British summer, the cardboard has been made waterproof.
Taking inspiration from a Japanese architect, who has used cardboard to make big buildings including churches, Mr. Dunlop used cardboard material for his tents, which he called Myhabs.
The design won an award at the annual New Designers Exhibition after Mr. Dunlop graduated from his product design degree and he decided to try to turn it into a business
To raise money for the idea, he toured the city’s private companies which fund new business and found a supporter in the finance group Mint. He introduced his idea to four of Mint’s directors and won their support. Mint has committed around £500,000 to MyHabs and taken a share of 30 per cent in Mr. Dunlop’s business. The first Myhabs should be tested at festivals this summer, before being marketed fully next year.
Mr. Dunlop said that the design, which accommodates two people, could have other uses, such as for disaster relief and housing for the London Olympics.
For music events, the cardboard houses will be ordered online and put up at the sites by the Myhabs team before the festival-goers arrive and removed by the company afterwards. They can be personalized and the company will offer reductions on the expense if people agree to sell exterior (外部的) advertising space.
The biggest festivals attract tens of thousands of participants, with Glastonbury having some 150,000 each year. Altogether there are around 100 annual music festivals where people camp in the UK. The events are becoming increasingly environmentally conscious.

It is difficult for doctors to help a person with a damaged brain
Without enough blood, the brain lives for only three to five minutes More often the doctors can’t fix the damage Sometimes they are afraid to try something to help because it is dangerous to work on the brain The doctors might make the person worse if he operates on the brain
Dr. Robert White, a famous professor and doctor, thinks he knows a way to help He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain.
Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, then he operated on them. He made the monkeys’ blood back to the monkeys’ brains. When the brain’s temperature was 10℃, Dr. White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again.
