We think our DNA is set for life, but it’s not. It shrinks over time and makes us age. Now researchers at the University of California at San Francisco believe that you actually can change and improve your DNA, which could, in turn, extend your life!
Though they don’t fully understand the mechanism, they know that tiny pieces of DNA called telomeres protect us by helping to keep chromosomes intact. Stress causes those oh-so-important telomeres to shorten, and the shorter they become, the more quickly our cells age and the more susceptible we are to everything from cancer to heart disease, diabetes, Alzheimer’s, osteoporosis -- and early mortality. How’s that for a list to avoid?'
