Midlife Habits Unlock Longer Healthspan, Studies Say
New Oxford and Harvard studies show midlife habits shape healthy life expectancy more than genetics. Not smoking, regular physical activity, healthy weight, good diet, and adequate sleep are the top levers; adding exercise variety lowers mortality risk. Women at 50 with 4–5 healthy habits gain about 34 extra disease-free years vs 24 for none; men gain 31 vs 24. The 50s are the most impactful decade for longevity, with habits compounding over time.
