Key Correlates of Longevity
Not Smoking

+10 yrs
Regular Exercise (3+ times/week)
Consistent moderate exercise correlates with 3–5 additional years and dramatically better quality of life.
+3–5 yrs
Healthy Weight (BMI 18.5–25)
Obesity (BMI 30+) is associated with 5–8 fewer years, driven by cardiovascular disease, diabetes, and other comorbidities.

Strong Social Connections

Note: These figures reflect population-level correlations from epidemiological research, not pure individual causation. Genetics, environment, healthcare access, and luck also play significant roles. Improving any single factor is beneficial; the greatest gains come from combining multiple healthy behaviors.
