AB- I like it that there’s so few of us. By-the-by, I give blood on a somewhat regular basis. I’ve been meaning to try to remember to go for the past few weeks. So with this handy reminder it will be in the morning. . . . . if Idon’t forget. ---

Yet another A+ checking in. I used to donate pretty regularly, but for some reason they don’t want your blood when you’re taking warfarin. 😃 Now that I’m off the meds, I need to see if I’m permanently blacklisted or not. > [@Todderbob](#): > > I donate as frequently as possible (on forced hiatus due to a tattoo) Future reference: I don’t know about where you live, but here in Milwaukee, if you get your tattoo from a place that’s on an approved list, there’s no year-long waiting period. If you plan on getting more ink and want to keep donating, ask your local blood center. > [@Tethered\_Kite](#): > > Do you know that the Japanese have developed a theory of personality based on blood type? I was actually going to comment that it’s a good thing the board’s not based in Japan, or we’d have people posting all kinds of theories about what the typing statistics say about the board’s members. 😃 > [@Juliana](#): > > It’s when I said that both of mine were O+ that the biology teacher pointed out (in front of the class) that this was absolutely impossible. :smack: Clearly the most intelligent and sensitive teacher ever. ---

> [@Shot\_From\_Guns](#): > > :smack: Clearly the most intelligent and sensitive teacher ever. Yup. But then again, this particular incident fueled one of my current passions: genealogy. So some good came out of the insensitivity. ---

Every blood relative I have ever known about was A+. We are all Ashkenazy Jews if that makes a difference. My daughter-in-law is B- and she had some treatment after her child was born to avoid Rh problems in any future pregnancy. ---

B+; wish I’d heard that ‘Be Positive!’ joke when I was young and found out, cause the only reason I remember \ is that my mom is B-. I knew that she had sorta-rare blood, and I knew that I had the same, but the common one. I actually had to look up blood rarities just now to see which one I was. 😛 What’s funny is that my mom has ALWAYS been the pessimist, and I have ALWAYS been the optimist. I can’t wait to tell her that joke. 😃 ---

I have absolutely no idea what my blood type is. I was introduced to a woman at a social gathering in Tokyo a number of years ago who asked me what my blood type was. I thought that had to be the strangest question to have been asked by someone I’d just met but, according to my friend anyway, Japanese people are really into blood types, and don’t feel it’s inappropriate to inquire, even of strangers. I was going to liken it to someone asking what your astrological sign is, but who even does that? ---

No idea what mine is. The doctors find out if they need to. I will never donate blood, so I don’t care about it otherwise. ---

Since it’s come up a few times, here’s the Wikipedia article on blood types as related to personality in Japanese culture: > **[Blood type personality theory](https://en.wikipedia.org/wiki/Blood_types_in_Japanese_culture)** > > The blood type personality theory is a pseudoscientific belief prevalent in Japan and South Korea, which states that a person's blood group system is predictive of a person's personality, temperament, and compatibility with others. The theory is generally considered a superstition by the scientific community. > One of the reasons Japan developed the blood type personality indicator theory was in reaction to a claim from German scientist Emil von Dungern, that Blood type B people were inferior.

It turns out that my blood type is the most common in the United States, O+. I feel like I’m not unique any more. [Previous page](https://boards.straightdope.com/t/what-is-your-blood-type/529028.md?page=4)
