the pineal gland doesnt uptake fluoride. the structures that create the pineal gland's psychological and/or metaphysical effects are calcite crystals, acting as piezoelectric transducers in response to rhythmically applied pressure in the cerebro-spinal fluid. over the age of 40, the calcite crystals become larger and less capable of this function, ie, "calcification of the pineal" is an unavoidable consequence of normal brain biology. https://ieeexplore.ieee.org/document/1285888
you mean Dr BrownSTAIN's book
if its fluoride then it isnt "calcification", its fluoridation
