A large-scale Canadian meta-analysis, drawing on 69 studies and millions of adult lives, has placed two of humanity's most ancient habits — movement and sleep — at the centre of the long struggle against dementia. The findings suggest that 150 minutes of weekly aerobic exercise and seven to eight hours of nightly sleep may reduce dementia risk by as much as a quarter, while prolonged sitting and disrupted sleep push that risk meaningfully higher. Though causation remains unproven, the consistency of the evidence invites a quiet reckoning: the ordinary rhythms of a life, tended carefully across
