Ahh Australia, the land of beautiful beaches, beautiful women and an unseen crystal meth epidemic.
In Australia, the legal mentality is such that if you sucker punch someone unconscious and they fall to the ground and crack their heads on the pavement and later die, usually it's determined that the punch isn't to blame but rather the head hitting the pavement. So using that mentality in this case, one could say that the fluoride is the sucker punch that interrupts the bodily systems and the diseases that follow are all unrelated.
