Reply #21: yes but it's rare

I just googled a short article which said these doctors had found 7 black women in their 30s who had pernicious anemia. They are guessing that most doctors would not diagnose the disease properly in this age group because they are not looking for it. They are assuming it is a disease of quote "Northern Europeans over age 40."

If you are still in your 30s, I would go a little easy on the doctors for not thinking of it right away, because it would be a lot more unusual.

The conservation movement is a breeding ground of communists
and other subversives. We intend to clean them out,
even if it means rounding up every birdwatcher in the country.
