Get your glow back.
Running increases the production of human growth hormone- your body's natural youth serum. This helps you produce new cells, which can make your skin look a lot more youthful.
The pounding of running sparks bones to regenerate, which is why older runners generally have higher bone density than non-runners of the same age.
Running protects your telomeres ( the shoelace cap-like DNA sequence coatings on the end of your chromosomes) which start to wear down as you age. The result.... You're less susceptible to sickness and inflammation.
