Dumb forum isn't allowing me to post a 2-letter answer...
No, those things do not go bad.
Oh, and since this is mainly about the pos/neg thing, my husband (self-diagnosed aspie) and brother (officially diagnosed PDD-NOS) are both positive also, but not sure what (except that they're not O). All three of us are caucasian as well.
but my brother is very Nt

Apparently this group is most commonly found in Norway, Denmark, Austria and Armenia.

My grandmother was 0- and lost two baby boys because of it (tragic). Her first, my aunt, and my mom, escaped the ravages of Minnie's immune system fortunately.
I have read that book on blood types and am a little skeptical, but I do seem to have a slight sensitivity to both dairy and wheat, which they say is typical of 0s.....
I can also eat a lot of steak and not have cramps- another supposedly 0 quality. We need meat apparently.

I could have had the same problems, but it would seem that my children must be neg.
I haven't seen the book, but am interested.
I had anibodies/anti-D as well.
One thing that annoyed me about this anti-D, was that my EX is O neg, I' m A neg & they still insisted upon testing me throughout the pregnancy, so I asked if they thought I was sleeping around.... that upset them a bit.
It's so bad in America we take our own aspirin to the hospital so as not to be charged $1 apiece for them!

If a RH neg has a baby with an Rh positive man, the RH neg mother's antibodies try to kill the baby (usually second baby).
If two people who are RH neg have a baby there is no problem, the actual blood group doesn't matter only the RH factor.

I have heard of a lot of this before, but it's hard to believe that a wealthy country treats it's citizens in this way.
I think it's a disgrace.
I've been tallying up responses trying to spot a trend, even though we're probably too small a sample size to be meaningful... (Please bear with me, numbers are NOT my strong point)
For Aspie/Autistic/Cousin respondants:
Negatives:
0 12
A 5
? 3
Positives
0 13
A 4
AB 1
B 2
? 1
0 negatives are known as the universal donors because other blood groups are able to accept our blood in transfusions which is WHY 0- are asked to give blood.
