The teeth are made of the same material that surrounds the pineal btw. Both are hydroxy-apatite. Which is converted into Fluoro-apatite. The pineal gland is responsible for melatonin production. Melatonin is a precursor for DMT in the human body, as well as various MAOI type compounds (such as Pinoline, related to the plant isolated alkaloid known as Telepathine).
But none of that matters now. Buy NANO if you want to survive the coming financial apocalypse. But not all of you.
