By Dana G. Smith If you've ever been to a high school reunion, you know that some people seem to age faster than others. Twenty-five years after graduation, one classmate can appear a decade younger than the rest, another a decade older. Scientists are working to quantify this phenomenon and put a number to a person's "biological age" by looking at their cellular health instead of how many years they've been alive. Researchers define biological age as "the accumulation of damage we can measure in our body". That damage comes from natural aging, as well as from our environment and behaviors. Several companies now sell tests for around $300 to calculate your biological age by analyzing your blood or saliva and comparing changes in your epigenome to population averages. But experts caution that epigenetic clocks can't actually tell you much about your own health. That's because they were designed to assess large groups of people, not individuals. Consequently, their results can be unreliable. Another problem with the tests is that it's unclear what to do with the results. Scientists don't know how to reverse someone's biological age — or whether that's even possible. "Expanding access and using more frequent testing to optimize health seems fairly reasonable to me," Dr. Poganik, an instructor at Harvard Medical School who researches biological aging said. But, "any claims of accurate, individual-level determination of biological age should be approached with caution." 【词汇过关】 请写出下面文单词在文章中的中文意思。 1.reunion英 [ˌriːˈjuːnjən] 美 [ˌriːˈjuːnjən] n. ____________________________ 2.age英 [eɪdʒ] 美 [eɪdʒ] v. ____________________________ 3.quantify英 [ˈkwɒntɪfaɪ] 美 [ˈkwɑːntəfaɪ] v. ____________________________ 4.quantity n. _________
