On the other hand, scientists are increasingly learning that aging and biological age are two different things, and that the former is a key risk factor for conditions such as heart disease, cancer and many more. In that light, aging itself might be seen as something treatable, the way you would treat high blood pressure or a vitamin deficiency.
Biophysicist Alex Zhavoronkov believes that aging should be considered a disease. He said that describing aging as a disease creates incentives to develop treatments.
"It unties the hands of the pharmaceutical (制药的.industry so that they can begin treating the disease and not just the side effects," he said.
"Right now, people think of aging as natural and something you can't control," he said. "In academic circles, people take aging research as just an interest area where they can try to develop interventions. The medical community also takes aging for granted, and can do nothing about it except keep people within a certain health range."
But if aging were recognized as a disease, he said, "It would attract funding and change the way we do health care. What matters is understanding that aging is curable."
"It was always known that the body accumulates damage," he added. "The only way to cure aging is to find ways to repair that damage. I think of it as preventive medicine for age-related conditions."
Leonard Hayflick, a professor at the University of California, San Francisco, said the idea that aging can be cured implies the human lifespan can be increased, which some researchers suggest is possible. Hayflick is not among them.
"There're many people who recover from cancer, stroke, or heart disease. But they continue to age, because aging is separate from their disease," Hayflick said. "Even if those causes of death were eliminated, life expectancy would still not go much beyond 92 years."

Comfort with food. When diet expert Judith Wurtman is stressed out, she does what a lot of people do this time of year: she reaches for food .But in her case, it’s a healthy rice cake or two. “My research suggests that carbohydrates (碳水化合物) raise levels of a brain chemical, which has a calming effect on the entire body,” says the MIT research scientist. “So signs of stress — such as anger, tension, and inability to focus — are eased.”
Run from your problems. Dr. Kenneth H. Cooper, who popularized aerobics (有氧运动) through his1968 book by that name, handles his own stress with a daily after-work run. He knows that physical activity reduces anxiety and depression. “Aerobic exercise is the best way to dissipate stress,”says Cooper.
Look to the light side. On his way to the hospital where his father was to have surgery Joel Goodman shared a hotel bus with anxious relatives of several patients. The driver began telling his stressed-out passengers a few jokes. “Then he did some magic tricks that had my mother and me laughing.” Goodman says. “In that five-minute ride he taught us that humor can lessen our stress.”
The surgery was successful, and Goodman was so moved by his experience that he researched laughter’s power. “A good laugh relaxes muscles, reduces blood pressure, restrains stress-related hormones and enhances the immune system (免疫系统),” he says.
Go green. Coffee, loaded with hidden sources of caffeine, stimulates (刺激) the nervous system and can make you feel stressed more easily. That’s why Arizona Doctor Andrew Weil, author of best seller Spontaneous Healing, does not take caffeine. “When I want gentle energy, I drink green tea. It contains a caffeine-like element”, Weil says. It also contains compounds that, some studies suggest, have anti-cancer effects.

But suppose the candidate lies or is less than completely honest.“This can be a serious problem for employers,” explains Alan Conrad, Chief Executive at Optimus Recruitment.“The most difficult liars to find are those who tell halftruths rather than complete lies.” Research shows that up to 75 percent of resumes are inaccurate on purpose.The most common practice is omission.
Interviewer should therefore concentrate on areas of uncertainty such as gaps between periods of employment and job descriptions that seem strange.“Focusing on these areas will force candidates to tell the truth or become increasingly dishonest.This is usually when people show their anxiety by their body language.Sweat on the upper lip, false smiles and nervous hand movements all indicate discomfort.”
Conrad does not suggest an aggressive policystyle. interview technique, but insists that close inspection of a resume is absolutely essential.Only by asking the right questions can you confirm the suitability of the candidate or put pressure on those who are being less than completely honest.
