Exercise is a Powerful Tool

Exercise affects the behavior of your muscle stem cells, which play an important part in your muscle repair process. This finding may also lead to new combination therapies that include stem-cell-based strategies to prevent age-related muscle loss

Telomere length -- the length of the terminal caps of your chromosomes -- is considered to be a marker of aging and health, and is also beneficially impacted by vigorous exercise

Recent research found that white blood cell telomere length in women who were moderately or highly active had a 0.07 standard deviation increase. Although associations were modest, these findings suggest even moderate amounts of activity may be associated with longer telomeres, and hence greater health and longevity. more by Dr. Mercola
