Sleeping 10 hours a night instead of 7.
linked to higher risk of heart and stroke death
For every 20 points higher on the top number (10 on the bottom), ages 40–69.
Your score counts it smaller: from 120/80, the same step is about 16% higher on the score’s own all-cause curve, a model assumption.
linked to lower risk of dying
Walking 7,000 steps a day instead of 2,000.
