What percentage of longevity is attributed to genetics according to new studies?

New research suggests that longevity is approximately 50% genetic and 50% environmental.

Do some people have genes that actively slow aging?

Yes, a small minority of people are born with rare genes that slow the aging process and protect them from age-related diseases.

Can the effects of anti-aging genes be replicated in others?

Researchers are working to understand how these genes function and aim to replicate their effects through drugs and other interventions.

Genes vs. Lifestyle: Unlocking Longevity Secrets

Recent scientific findings indicate that genetics play a more significant role in longevity than previously understood, with lifespan being roughly 50% genetic and 50% environmental. This contrasts with earlier studies that estimated a much lower genetic contribution. For most individuals, maintaining a healthy lifestyle—including diet, exercise, and sleep—remains key to a longer, healthier life.

However, a small percentage of people possess unique genes that naturally slow the aging process. These genetic advantages can offer protection against age-related illnesses like heart disease, Alzheimer's, and cancer, even if their lifestyle choices are not always optimal.

Researchers are now exploring ways to harness the power of these genes through drugs and other interventions. The goal is to potentially replicate their protective effects in the wider population. Furthermore, efforts are underway to personalize medical and dietary recommendations based on an individual's specific genetic makeup.
