@Suzette , you were right, Iodine is one of the most important nutrients a woman can get. It is a vital ally against graves disease, fibrocystic breasts, endometriosis, etc.
You don't want to ingest the topical, synthetic iodine that kills germs on wounds, but Lugolls Iodorol is such a lovely supplement, and yes, you can test to see if you need it by rubbing a bit on your abdomen. The synthetic, highly toxic, topical Povidine is man made, from nasty things that can harm the human body, but natural Iodine comes from kelp and seawater, and every cell in your body craves it. The type of iodine in iodized salt, and in many cheap supplements is kind of bad for you, as it's not well absorbed by the body. But if one can't afford a natural, kelp-sourced iodine supplement, it's good enough.
It sounds like your friend knows only about allopathic medicine. There's a whole natural world of holistic medicine that works in harmony with the human body, and many of the rules are in opposition with Westernized Medicine.

On your original subject, I was just mentioning this very thing to another person earlier this week.
When asked a direct question, I often start stuttering and fighting through a very limited spoken word bank to try to create a sentence that makes just a little sense. But it usually makes me sound like a liar and a fool. I hate it.
When I write, ideas often flow, but speaking, especially when faced with a direct spoken question, even if they ask it in a friendly conversation, my mind goes blank, and I nearly go back to nonverbal. Sometimes I can't even speak at all.
