    Roenneberg et al. (2012) reported ~69% experience at least one hour of social jetlag, not 87%.

    Before

    social jet lag affects approximately 87% of the population

    After

    social jet lag affects approximately 69% of the population

    Why: Verified live article (post 1294, how-does-sleep-work): body already correctly reads 69%. Checked FAQ (4-step op-sequence, 5 items) and excerpt independently - neither mentions this specific Roenneberg percentage. Already correct, no PUT needed.
