I don’t think that there’s anything to the idea that water problems can mess up your thyroid — I don’t think they turned up anything when they tested the VP mansion water. I think they just felt that they should test something since everyone in the house got thyroid problems at the same time. If you write to Barbara Bush, why don’t you ask her about it. Tell her that all of us on the BB are curious, and maybe see if you can get her to post a message here.
