"The poet Schiller used to keep rotten apples under the lid of his desk and inhale their pungent bouquet when he needed to find the right word. Then he would close the drawer, although the fragrance remained in his head. Researchers at Yale University discovered that the smell of spiced apples has a powerful elevating effect on people and can even stave off panic attacks. Schiller may have sensed this all along. Something in the sweet, rancid mustiness of those apples jolted his brain into activity while steadying his nerves."
