A migraine（偏头痛）can cause disabling pain. People may not feel back to normal for hours or even days. Migraines are most common among young adults and middle-aged people. In the United States, about eighteen percent of women and six percent of men report having migraines.

People who suffer from migraines can find that different “triggers（诱因）”in different people may get a headache started. Stress can act as a trigger. So can chocolate in some people. Many migraine sufferers say hot weather and low barometric pressure（大气压）can act as triggers. But researchers say they do not have much scientific evidence of that — until now.

 In a new study, a team examined the medical records of seven thousand hospital patients. The patients had visited the emergency room at Beth Israel Deaconess Medical Center in Boston, Massachusetts, because of a headache. More than two thousand of them had been found to have a migraine.

 The team then compared those records to weather conditions in the twenty-four hours before the hospital visits. For every increase of five degrees centigrade in air temperature, the patients had a seven and one-half percent higher risk of migraine. Decreases in barometric pressure two to three days before the visit also appeared to trigger headaches.

 The researchers found no evidence that air pollution influenced headaches. But they could not rule out the possibility of a smaller effect.

 A separate study has found that age, gender and where a person has extra body fat may affect the risk of migraine. It found that overweight people between the ages of twenty and fifty-five may have a higher risk. On average, those who were larger around the middle were more likely to have migraines than those of the same age with smaller waistlines.

 The study involved twenty-two thousand people. It was led by Lee Peterlin. She says early results suggest that losing weight in the stomach area may help younger people who experience migraines, especially women.

Head held high, hands firmly gripping her walker, Mary Arnott, 99, walks slowly with dignity through the women’s changing room at the Etobicoke Olympium pool, past the teenage girls who have been blow-drying their hair for half an hour, into the mist of the showers, then out the door and first one into the heated pool. She jumps over to the shallow end, stopping to talk to friends—everyone knows Arnott here;she swims twice a week and treats it as a job—about their children, the viciousness（谬误）of bridge and their health.

 In fact, Arnott is an exception to the exception. Not only has she lived 20 years past the average lifespan for Canadians, she’s healthy, her mind is sharp and she lives independently.

Born in Brooklyn on May 28, 1909, Arnott was raised on Staten Island. She survived scarlet fever（猩红热）, helped bring up four siblings（兄弟姐妹）after her mother died in 1923 and worked as a secretary in New York City for 12 years, earning＄35 a week and a＄150 bonus at Christmas.

 Now she’s happy living in a one-room apartment with a kitchen and a bathroom in her daughter’s house. She wears a hearing aid, does the cryptic crossword（有隐义的纵横字谜）with a magnifying glass, and can’t really explain why she has lived so well so long.

Until recently, she has still liked to drink red wine—she used to drink two glasses before supper each day. It’s more likely genes, she admits. Her interest in other people and life in general may have had something to do with it. Asked if a star photographer can take her picture at the pool, Arnott seems cheerful.

“I look good in a swimsuit, ” she says, nodding her head firmly. “I look better in a swimsuit than I do in pants. ”
