think about what is being set up. as halogen imbalanced as people are, what if there was a nuclear incident? what if you could get your hands on potassium Iodide then? what if you had never taken Iodine before and were loaded with mercury, bromine, lead and fluoride? the reactions in time of emergency could easily cause peoples hearts to fail them due to the extreme level of stress at the time.
i suggest people at least experiment with Iodide before this happens, especially in major cities(terrorist targets) and down wind of any nuke facility.
