[Comment] Physical activity lowers mortality and heart disease risks

In The Lancet, Scott A Lear and colleagues1 report results from a large cohort of 130 843 participants from 17 countries (including four low-income countries and seven middle-income countries) investigating the beneficial dose-dependent associations of all forms of physical activity with reduced mortality and cardiovascular disease risks.1 This is another confirmation that physical activity has definite and dose-dependent benefits for lowering risks of all-cause mortality and cardiovascular disease (heart attacks, stroke, and heart failure).
