that's interesting... I was about to ask about the connection between the two some days ago (after I had my blood type known with the sponsorship(?) of our school)... and now the question is here!
I like this one I got from
http://www.bloodgivers.com/character.asp better... it has a rather nearer description of me than the one you gave... here:
Type AB "Care-Free"
Social, Easy-going, Sympathetic, Diplomatic, Outgoing, Laid-back, Creative, Unpredictable, Artistic, Flexible, Moody and Brooding.
Blend of opposites. Shy with some and bold with some. Introvert and Extrovert. Unpredictable and may seem to have calm exterior. Strong creative strain. Good at spotting problems and skirting them. Like city environment. Get bored easily. Everything they do is compelling. Never take things for granted. Appear mysterious. Contribute harmoniously to society.
Dislike to touch or be touched by others.
found the last of your description of AB most true for me: having difficulty making decisions :D
