That headline is another “sounds scientific, but oversells a weak link” type of claim.
There has been research looking at whether blood type (like A, B, AB, O) is associated with longevity, including studies on people who reach 100+. Some findings suggest slight differences in disease risk between blood types (for example, clotting, heart disease risk), but:
- There is no strong or reliable evidence that any blood type consistently “has a higher likelihood of living to 100”
- Longevity depends far more on:
- genetics beyond blood type
- diet and physical activity
- smoking/alcohol use
- healthcare access
- stress levels and sleep
- random chance
Blood type is a very small biological factor compared to those.
So the accurate takeaway is:
👉 Some studies explore associations between blood type and certain health risks, but blood type is not a predictor of living to 100.
If you want, I can break down what actually has the strongest evidence for increasing lifespan (spoiler: it’s boring but effective habits, not genetics “hacks”).
