Famous quotes containing the words sneeze and/or reflex:

    Frau Stöhr ... began to talk about how fascinating it was to cough.... Sneezing was much the same thing. You kept on wanting to sneeze until you simply couldn’t stand it any longer; you looked as if you were tipsy; you drew a couple of breaths, then out it came, and you forgot everything else in the bliss of the sensation. Sometimes the explosion repeated itself two or three times. That was the sort of pleasure life gave you free of charge.
    Thomas Mann (1875–1955)

    As a medium of exchange,... worrying regulates intimacy, and it is often an appropriate response to ordinary demands that begin to feel excessive. But from a modernized Freudian view, worrying—as a reflex response to demand—never puts the self or the objects of its interest into question, and that is precisely its function in psychic life. It domesticates self-doubt.
