A little less "cool" guy talking about the thyroid, pituitary,adrenal axis. + about the T3,4, why these tests simply not give you the right picture of whats going on. Connected to the immune system, chemical stress, Iodine, selenium, fluroide, bromine etc. From approx 31 minutes good info about Hashimoto`s. A must see IMO.
Ps; look at the x-ray at approx 20 minutes; a 55 year old mother vs her 17 year daughter.
