Stats: Biological age of brisk walkers up to 16 years younger

A study of genetic data from more than 400,000 UK adults revealed a clear link between walking pace and a genetic marker of biological age. Confirming a causal link between walking pace and leucocyte telomere length (LTL) -- an indicator of biological age -- the Leicester-based researchers estimate that a lifetime of brisk walking could lead to the equivalent of 16 years younger biological age by midlife. It's another strong reason to encourage brisker walking, when feasible, particularly in independent living settings.
