Your "babbling" JRs was exceptionally well done. (FYI, your spelling was very close -- It is spelled hemochromatosis, for those wishing to google and learn more.) Of interest perhaps is that the Center for Disease Control has estimated that one in every 200-250 Americans have hemochromatosis and don't know it.
Obviously, you've had a crash course out of necessity, JRs, and you're a wonderful student -- some of the best "medicine" your husband can receive. The HFE gene marker was discovered in the mid-90s and the genetics folks have begun some experimental trials that will hopefully yield some treatment beyond removing a bag of blood at a time.
My very best wishes to you, your husband and all kith and kin! And thank you for sharing this point.
