⚠What it shows: Strong but still correlational: a sweep of a decade of studies, most of which followed people rather than testing exercise on them, so it shows patterns in who lives longer rather than proof that the exercise caused it. The sweet spots it describes are averages across big populations, not tested limits for any individual.Meta-analysis · Mo Med
