Nose

Anatomically, a nose is a protuberance in vertebrates that houses the nostrils, or nares, which admit and expel air for respiration in conjunction with the mouth. Behind the nose are the olfactory mucosa and the sinuses. Behind the nasal cavity, air next passes through the pharynx, shared with the digestive system, and then into the rest of the respiratory system. In humans, the nose is located centrally on the face; on most other mammals, it is on the upper tip of the snout.

    I knew this guy that broke my sister’s nose when I was a kid and I always thought that’s why he became a priest. He tied her up in a chair and it was like, you know, I thought he was like overcompensating.
    Blake Edwards (b. 1922)

    There is no such thing as a perfect leader either in the past or present, in China or elsewhere. If there is one, he is only pretending, like a pig inserting scallions into its nose in an effort to look like an elephant.
    Liu Shao-Ch’I (b. 1898)

    You may tell a man thou art a fiend, but not your nose wants blowing; to him alone who can bear a thing of that kind, you may tell all.
