The open access study noted here is one of many to show that greater levels of physical activity correlate well with a reduced risk of age-related disease. It isn’t possibly to reliably live to extreme old age on the back of a good exercise program, but that physical activity does reliably improve the odds of experiencing better rather than worse health in later life. Even small benefits can be worth chasing when they cost little and are reliably obtained, so long as that pursuit doesn’t distract from far more important initiatives. Exercise is beneficial, but it is no substitute for the rejuvenation therapies presently under development.
Successful aging has been defined as not suffering from chronic diseases, having optimal social engagement and mental health, and a lack of physical disability. Numerous studies have found that physical activity decreases the risk of many chronic diseases and increases longevity. However, the association between physical activity and successful aging has shown heterogeneity across studies. Some studies have shown either a lack of or a weak independent association between physical activity and successful aging; however, other cohort studies as well as systematic reviews have shown that higher levels of physical activity was associated
