Instead, centenarians tend to share a combination of factors:

Lower rates of chronic disease

Healthy cardiovascular systems

Strong genetic resilience

Active lifestyles

Balanced diets

Social connection and mental engagement

Some studies have looked at whether certain blood types appear more frequently among centenarians, but results are inconsistent and often influenced by small sample sizes.

In other words, there is no scientifically established blood type that guarantees or strongly predicts a longer life.

Genetics: the real foundation of longevity

While blood type is genetic, it represents only a tiny fraction of the human genome.

True longevity-related genetics involve complex interactions between thousands of genes that affect:

DNA repair

Inflammation levels

Metabolism

Immune system function

Cellular aging

Some people inherit genetic advantages that make them more resilient to age-related diseases. Others may have genetic variations that increase risk.

However, even strong genetic advantages do not guarantee long life. They simply influence probabilities.

Many researchers agree that genetics may account for roughly 20–30% of lifespan variation, while environmental and lifestyle factors make up the rest.

Lifestyle has a much larger impact

When studying long-lived populations around the world, researchers consistently find that lifestyle plays a major role.

Common traits among people who live longer include:

1. Balanced diet

Diets rich in vegetables, fruits, legumes, whole grains, and healthy fats are commonly associated with better health outcomes.
