Below are some smart ways to stay healthy suggested by some American experts.
Drink More Coffee
When was the last time you heard a doctor use the word miracle? Well, wake up and smell the coffee: “It’s amazing,” says liver specialist Sanjiv Chopra, MD, professor of medicine at Harvard Medical School. “Coffee is truly a lifesaving miracle drug.”
Though he says it’s still a “scientific mystery” how a simple cup of coffee works its wonders in the body, large epidemiological studies have repeatedly proved its astonishing benefits.
“Drink it black, or at most put a little skim milk in it” to minimize calories, Dr. Chopra recommends. He drinks at least four cups a day himself, though most people should limit themselves to two. And no, he jokes, “I’m not sponsored by Starbucks.”
Take a Walk for Your Memory
Aerobic (有氧运动的) exercise is good for your body, great for your mind, according to the latest research from brain-fitness pioneer Arthur Kramer. Every year, an area called the hippocampus, which is key to memory, shrinks by about 1 to 2 percent, increasing the risk of dementia (脑衰) as the years roll by. However, Kramer’s new investigations reveal that the hippocampi of adults who walked briskly for about 45 minutes three times a week grew by about 2 percent over the course of a year, preventing age-related shrinking.
It’s never too late to start exercising, Kramer says; volunteers in his research were between 55 and 80 years old and hadn’t exercised at all. And it doesn’t need to be backbreaking. “Anything that raises your heart rate seems to work,” he says. “Walking is fine. Just find something you like and do it.”
Early to Bed, Early to Eat
“Being a night owl might increase your waistline,” says sleep expert Michael Breus, PhD. People who stay up late and sleep late tend to eat more fast food and consume more of their calories after 8 p.m. than do normal sleepers.
“One of the easiest things that anyone on a diet can do to improve her results is go to bed and wake up at the same times every day,” Breus says. “This way, your body knows when to sleep and is much more efficient. Organize your eating, too, by trying to eat meals at the same times every day. Avoid eating after 8 p.m., and don’t miss morning meals by sleeping in.”
Use the 20-Second Rule
What’s the difference between having a goal and actually accomplishing it? Just 20 seconds, says positive-psychology specialist Shawn Achor. Researchers have learned that if we can cut 20 seconds off the startup time required for a task, we’re much more likely to follow through. So, for example, if you want to work out in the morning, place your shoes and exercise clothes next to your bed the night before. If you want to praise people more, put thank-you notes and a pen on your desk.
Imagine the Worst to Feel Better
Don’t count your blessings; subtract (扣除) them. “Consciously spend a few minutes imagining what your life would be like without the good things,” says Timothy Wilson, a psychologist at the University of Virginia. You’ll experience stronger feelings of love, gratitude, and happiness when you think about what life would be like without the people and things you love. “And they’ll seem surprising and special again,” he adds.

HIV. The tests are the first step in human clinical trials of two vaccine candidates developed at the University
of Cape Town.
These experimental AIDS vaccines are the first from Africa to reach testing in people. The National
Institutes of Health in the United States provided assistance. Testing with twelve people began earlier this year
in Boston, Massachusetts.
South Africa has more than five million people infected with HIV, the largest number of any country.
South Africa launched the tests last week as the International AIDS Society held a conference in Cape
Town. Other human trials of possible vaccines are taking place around the world. Scientists hope to get some
results later this year.
But during last week's conference, experts reported the first decrease in international financing for AIDS
vaccine research. They said funding dropped from about 930 million dollars in 2007 to 870 million last year.
Also at the conference, scientists presented the latest findings about new mothers infected with HIV. Two
studies showed ways in which anti-HIV drugs could permit infected women to breastfeed their new borns
with less risk of passing the virus to them. The research was done in Cameroon, Ivory Coast, South Africa
and Zambia.
In one study, infected mothers began to take three anti-HIV drugs while breastfeeding for up to six months.
In a second study, the babies were given medicine, instead of their mothers. The babies received one drug
every day during six months of breastfeeding.
The researchers said both methods greatly reduced the risk of HIV infection.
Laura Guay is Vice President of research at the Elizabeth Glaser Pediatric AIDS Foundation, which
supported the research. Doctor Guay says the problem in sub-Saharan Africa is the limited availability of anti-
retroviral drugs.
LAURA GUAY:"We know that only about 33 percent of women have access to a program that actually
has services in place to prevent mother-to-child transmission. So the first challenge is, how do we reach all
the women who do not have access to a prevention program?"
B. the vaccine has been developed in South Africa
C. the United Nations will offer it assistance
D. it has enough volunteers who are AIDS carriers
B. Newborns are easily got infected with HIV if their mothers got AIDS.
C. Anti-HIV drugs help mothers infected with AIDS avoid transmitting HIV to their babies.
D. Both the mother and the newborn can take the anti-HIV drugs.
B. South Africa was the first country which began the test of the vaccines.
C. Anti-HIV drugs have less effect on babies than on their mothers who are affected AIDS.
D. Only those women from rich families have access to anti-HIV drugs.
B. The lack of volunteers.
C. The difficulty in human clinical trials.
D. Too many AIDS patients.
