I'm O negative and have always seemed to get the worst of it when out when friends.
I recently took up cigar smoking (yes i know) and anecdotally have found that I don't get bit as often if I've been smoking recently...to the point of watching someone six feet from me get destroyed while they avoid me completely. My father-in-law has been smoking for 50+ years and they ignore him.
