Ok, Im O+, half caucasian, half I dont know what category.
I only just found out this year, after years of being asked by Japanese and Korean friends. They all told me what they thought my blood was, and low and behold they were right!
Apparently O and A are the perfect match
B people can tend to be a little crazy, there is a movie in Korea called "My boyfriend is B type" since then any person who is B, gets sheepish and doesnt like to say.
My boyfriend is Asian O+ alos, but I dont know if thats a good thing or not.
When I was in Cambodia, I gave blood, it was the first time, and since there are so many O people out there, I dont know that I will do it again.
