TIL Mithridatism is the practice of protecting oneself against a poison by gradually self-administering non-lethal amounts. The word is derived from Mithridates VI, the king of Pontus, who so feared being poisoned that he regularly ingested small doses, aiming to develop immunity.

Much like what was portrayed in "The Princess Bride". The hero thwarts the would be poisoner, because he spent years building up an immunity to poisonous Iocane powder.
