The Swedish study tracked 12 blood markers in 44,637 people over 35 years—and found centenarians typically had:
✅ Lower glucose (<6.5 mmol/L)
✅ Lower creatinine (healthier kidneys)
✅ Lower uric acid (less inflammation)
✅ Moderate cholesterol (not too low, not too high)
💡 Key insight: It wasn’t one magic number—it was consistently healthy ranges across multiple systems that predicted longevity.

So What Does Blood Type Have to Do With Longevity?
Research here is limited and mixed—but a few patterns emerge:
Blood Type O: Slight Edge?
Associated with 10–15% lower risk of cardiovascular disease (per Critical Reviews in Clinical Laboratory Sciences, 2021)
May have lower risk of blood clots (type O has lower von Willebrand factor)
