399 TED-ED 预测你衰老质量的三大关键指标

If you want to learn a tree’s age, you can count their rings. When it comes to humans, scientists have yet to find any visible traits that mark our age with the same specificity. But in the past few decades, they’ve discovered small, invisible markers hidden within the body that do change over time. Juulia Jylhävä shares what these markers can tell us about our health, history, and future. [Directed by Flaka Kokolli, Diellza Franca, Flammorum Animation Studio, narrated by Bethany Cutmore-Scott, music by Cem Misirlioglu].若想知树龄，可数年轮。至于人类，科学家至今尚未发现能像树木年轮那样精确标记年龄的可见特征。但过去几十年间，他们发现人体内存在着随时间变化的微小隐形标记。尤莉亚·尤尔哈瓦（ Juulia Jylhävä ）将揭示这些标记如何揭示我们的健康状况、生命历程与未来走向。
