Just a quick lowdown on the flouride issue:
Illegal in Israel.
Causes thyroid dysfunction.
Current 'accepted' measure of thyroid function, the TSH, is easily masked by synthroid.
TSH is called normal at 5 but a value of 5 causes unacceptable results in babies and had to be changed for pregnant women to a normal value of 2.5 (the bitter highest any human should have) because of lawsuit threats.
The US is likely suffering from flouride effects manifested by a new lower average temperature. https://www.scientificamerican.com/article/are-human-body-temperatures-cooling-down/
This all has the appearance of a scheme by the Rockefeller controlled medical entities to cover up that flouride in the water contributes to making the population sick/tired/slow (dumb). Matching their goals as stayed in the podesta email.
Bottomine is only a T3 test will tell you if you are operating at a normal level. Simple doctors may say it is an intracellular hormone but enough must spill into the blood to fully activate tissue compartments that don't make their own-especially the glial cells of the brain.
