Walking fast is the key to a long life? Study links pace to aging

Live 16 years longer by walking fast

A brisk walk could help add 16 years to your life, a new study finds. Researchers at the University of Leicester have discovered a link between a person’s walking pace and the rate at which they age.

Specifically, a lifetime of brisk walking leads to longer telomeres. These are the protective “caps” on the ends of your chromosomes — sort of like the plastic tabs on your shoelaces. Although they don’t carry genetic information, telomeres play a vital role in keeping DNA stable.
