Have you ever heard the saying that a frog will boil to death if the heat in the pot is turned up gradually?
Urban myth has it that if you put a frog in a pot of boiling water it will instantly leap out. But if you put it in a pot filled with pleasantly tepid water and gradually heat it, the frog will remain in the water until it boils to death.
