You know the classic experiment where scientists inserted a wire that stimulated the pleasure center of the rodent's brains when a button was pushed, then let the rats push the button for themselves whenever they wanted, only to discover that the rats would push it and push it, passing up food and drink (etc.) in favor of pushing the button?
That's why I can't have Cool Ranch Doritos.
Sometimes I forget. Thank heavens the bag eventually runs out.
