For years,  aging  was explained almost exclusively by  genetics ,  lifestyle  , and  daily habits . However, recently a hypothesis as striking as it is unexpected has begun to gain traction:  blood type  may indirectly influence how the body ages. Although it is still a developing field, several scientific studies suggest that blood type could be related to certain biological processes linked to cellular deterioration.

Blood type ,  primarily known for its importance in transfusions and medical emergencies, defines specific characteristics of cells and the immune system. Recent research indicates that these differences not only affect blood compatibility but also the  inflammatory response ,  circulation ,  oxidative stress , and predisposition to certain chronic diseases—all factors closely associated with aging.
