Arguing Against a Correlation Between Blood Type and Aging

Does blood type in any way affect longevity? A resounding "maybe" from what little work exists on the topic, which suggests that if there is any effect then it is small in comparison to other factors. But we'll never know unless the research community looks into the matter, and so here is another batch of evidence to add to the pile: "Centenarians are the best example of extreme human longevity, and they represent a selected population in which the appearance of major age-related diseases, such as cancer, and cardiovascular diseases among others, has been consistently delayed or escaped. The study of the long-lived individual genetic profile has the purpose to possibly identify the genes and the allelic variations influencing extended life expectancy, hence considering them as biomarkers of age-related diseases onset and development. The present study shows no significant differences between allelic variations of ABO blood groups among a group of centenarians from Western Sicily."
