染色體的末端——端粒——會隨著年齡的增長而縮短，讓我們更容易生病。也許你會認為我們對此無能為力就，但最新研究表明，生活習慣的改變可以激發一種增加端粒長度的酶，而且其他研究也發現合理飲食和鍛煉能保護端粒?？磥斫】档纳盍晳T能從細胞級別減緩衰老。
As we age, the ends of our chromosomes -- called telomeres -- become shorter. This makes people more vulnerable to disease. You might think there's nothing you can do, but new research suggests otherwise. In a pilot study, lifestyle changes boosted an enzyme that increases telomere length. Other studies also find diet and exercise can protect telomeres. So healthy habits may slow aging at the cellular level.
