We all know the story of how to boil a frog to death (Frog lovers: I’m not suggesting you do so, I’m just trying to make a point here.) The premise is that if you suddenly plopped a frog into boiling water, it would jump out. But if the frog is put in lukewarm water, which is then very slowly brought to a boil, it won’t recognize the danger. And before the frog knows what is happening, it will be cooked to death.
