As you may remember from biology class, we have 23 pairs of chromosomes, which determine everything from our gender to our hair and eye color. Each is capped by a protective bundle of DNA called a telomere. Telomeres buffer our genetic material from damage as our cells divide and replicate. But as we age, our telomeres slowly grow shorter.
Here’s the amazing thing: Although you can’t change your DNA, you can change your telomere length. And that’s the key to turning back the clock.
