Longevity simply refers to how long someone lives. Biological aging refers to the gradual molecular, cellular, and physiological changes that occur throughout the body over time.
A factor associated with a slightly different risk of one disease does not necessarily make the entire body age faster or slower.
For example, if a blood group were associated with a different statistical risk for a particular cardiovascular condition, that would not automatically mean people with that blood group have younger skin, healthier joints, slower cognitive aging, or greater overall longevity.
The human aging process cannot realistically be reduced to a single characteristic
