Advances in health, education and disease prevention and treatments are making human life longer. But what you may not know is that some seemingly unimportant things can also influence how long and how well you’ll live. Here is the latest research on longevity（长寿）signs.
Sign 1： Your Mom Had You Young
If she was under age 25, you’re twice as likely to live to 100 as someone born to an older mom. They think that younger moms produce healthier babies.
Sign 2： You’re a Tea Lover
Both green tea and black tea contain catechins（儿茶酚）, something that helps blood vessels（血管）relax and protects your heart. In a study of more than 40,500 Japanese men and women, those who drank five or more cups of green tea every day had the lowest risk of death from heart disease. Other studies about black tea showed similar results. You really need only one or two cups of tea daily to start doing your heart some good. Ready-to-drink tea doesn’t offer the same health effects. “Once water is added to tea lees, their catechins disappear within a few days,” says a professor. Also, some studies show that adding milk may get rid of tea’s effects, so stick to just lemon or honey.
Sign 3： You’d Rather Walk
“Fit” people—defined as those who walk for about 30 minutes a day—are more likely to live longer than those who walk less. So take a walk during your lunch hour, do exercise around the field while your kid is at soccer practice—try by hook or by crook to move a little more, every day.
Sign 4： You He Strong Legs
Lower-body strength translates into good balance, flexibility, and power, which, as you get older, play an important part in reducing your risk of falls and injuries, leading to better health. Now you see, it is necessary to strengthen your lower-body. But the question is： how?
1. Which of the following is TRUE about tea?

B. One or two cups of tea daily are best for your heart.

C. Choose carefully.D. Work out new ways.
