How strong is the evidence for Daily Physical Activity?

Large prospective cohort studies, including a Taiwanese study of over 400,000 people and a pooled analysis of more than a million participants, consistently show that non-exercise daily movement is inversely related to mortality, even at volumes well below formal exercise guidelines. That evidence is currently rated strong (84/100), built on 6 published studies, including 1 meta-analysis -- enough for real confidence in the effect.
