Blood Type-ology

When I was younger, I noticed an interesting fact about video games that came from Asia, particularly fighting games. If you looked at character profiles in, say, Street Fighter II, you'd notice the usual height and weight . . . but also blood type. I never really quite understood why it was relevant that Zangief was Type A.

This question came to mind today when one of my students asked me, "Teacher, what is your blood type?" I responded, truthfully, that I couldn't remember. The kids were surprised by this. What was even more surprising is that one student opined, "I think you are either A or O." I asked what made her think this, and she replied "the way your face looks."

This whole thing left me rather puzzled, so I did some research. It turns out that, according to Wikipedia, in Japanese culture blood types correspond to different personality types. This would appear to be the case in Korea as well, judging by the Korean film My Boyfriend is Type B.

Look at the list below. What do you think my blood type is? If you have access to my personal medical history, no cheating (Dad).
