The claim “If you have this blood type, you are more likely to live past 100” is a popular social media headline, but it oversimplifies the science.
Some studies have explored whether blood type is linked to longevity, but no blood type guarantees a longer life. Living past 100 is influenced much more by factors such as:
- Genetics and family history
- Diet and physical activity
- Not smoking
- Managing blood pressure, cholesterol, and diabetes
- Social connections and mental well-being
- Access to healthcare
Research has found that certain blood groups may be associated with slightly different risks for specific conditions. For example, people with type O blood may have a lower risk of some clotting-related problems, while people with non-O blood types (A, B, AB) may have a higher risk of certain cardiovascular and clotting issues. These differences are small and do not predict an individual’s lifespan.
A blood type alone cannot tell you whether you will live to 100. Healthy habits and medical care have a much larger impact.
