"Incompatible" Blood Types and Life Expectancies

Every now and then, I read or hear about a couple who are warned by their family doctor they have "incompatible blood types" and likely may not have children, or children who survive birth.

I have no records, but I was told that my parents were informed of such (WW2 era). They promptly went on to disobey the natural law outlined by a medical professional, and had 6 healthy children (of whom I am #3). Of course, every time my mother went into labor, the attending doctors went into a panic.

We all have A- blood type, which I understand isn't really "rare" but is not quite so common.

My grandparents (both sides of the family), parents, and all uncles and aunts (again both sides of the family) passed away at or before age 60 (various causes, mostly diseases and poor lifestyle damaging internal organs). My 2 older bothers were both gone (within 2 weeks of each other) at age 60 and 59.

I am 63 and healthy, the oldest in my family line for three generations. Non-smoker, non-drinker, vegetarian, and gluten-free. Exercise 3 to 5 times weekly, 1.5 to 2 hours per evening (karate instructor). No accidents in my life, no broken bones, handle stress well, and all the other good stuff. Personal stats from three major insurance companies indicate I will live to be an intolerable old fool at age 93 to 97 years (apologies in advance for the next 30 or so years of drivel)...

Of course, my (slightly) younger siblings are watching me very carefully. But they haven't embraced any of my lifestyle habits, either...

Has this anything to do with blood types? What are the stats on deaths of people with A- blood type?
