A new study from Stanford University School of Medicine tracked 500 older runners for over 20 years, finding that regular running delays disability and reduces the risk of early death. The study's findings support the theory that 'comparing morbidity' - compressing the period of declining health - can extend high-quality life.
A study of 5,952 twins and 1,357 siblings found that voluntary exercise is not associated with reduced anxiety and depression symptoms. Instead, a shared genetic factor may link exercise behavior to mood disorders.
