過度の興奮に慣れた人は,胡椒（コショウ）を病的にほしがる人に似ており,そのような人は,ついには,ほかの人なら誰でも窒息しそうなほど多量の胡椒でさえ味がわからなくなる。
A person accustomed to too much excitement is like a person with a morbid craving for pepper, who comes last to be unable even to taste a quantity of pepper which would cause anyone else to choke.
From: The Conquest of Happiness, 1930, chap.4:Boredom and excitement
