Here are the 7 simple science-backed rules for living longer according to National Geographic and longevity expert Eric Topol:

Genetics Don’t Dictate Your Fate
Your genes account for only about 20% of human longevity. The other 80% comes down to lifestyle, environment, and choices. Healthy habits can provide 5–7 more years of good health, regardless of family history.

Exercise Is the Best “Biohack”
Regular physical activity—ideally 150+ minutes per week of moderate movement (like brisk walking or dancing), plus strength training at least twice weekly—has the biggest impact on healthy aging. Exercise benefits the whole body, reducing inflammation and the risk of major diseases.

Adopt the Mediterranean Diet
Emphasize “eating the rainbow” with a variety of fruits, vegetables, whole grains, beans, lean proteins, and healthy fats. This diet is strongly linked to a lower risk of heart disease, diabetes, and cognitive decline. Avoid ultra-processed foods, which are linked to over 30 health issues.

Prioritize Quality Sleep
Poor sleep accelerates biological aging. Aim for consistent sleep and wake times, 7–9 hours of nightly rest, regular movement, and not eating close to bedtime. Proper sleep supports brain and body repair and may defend against Alzheimer’s and other diseases.

Cultivate Social Connections
Strong relationships and regular social interaction are as important as diet and exercise. Social isolation increases risks comparable to smoking half a pack of cigarettes a day, raising the likelihood of heart disease, dementia, depression, and premature death.

Manage Stress Effectively
Chronic stress accelerates aging and increases the risk of major diseases. Practices like mindfulness, relaxation, community engagement, and activities that bring joy can help regulate stress and support healthy aging.

Live With Purpose
Knowing your purpose—what gives meaning to your life—adds years to your lifespan. Engaging in meaningful roles within your family, work, and community correlates with longevity and mental well-being^[1][2][3].

These principles are supported by strong scientific evidence and observed in the world’s longest-lived populations. They offer practical, accessible steps to not only increase lifespan, but also improve the quality of your years.
