The effect of hormonal agents on the reproductive system is complex. It is believed that combined hormonal contraceptives work primarily by preventing ovulation and thickening cervical mucus. Progestogen-only contraceptives can also prevent ovulation, but rely more significantly on the thickening of cervical mucus.

    A mechanism of some kind stands between us and almost every act of our lives.

    I’ve never known a Philadelphian who wasn’t a downright “character;” possibly a defense mechanism resulting from the dullness of their native habitat.
    Anita Loos (1888–1981)

    To play is nothing but the imitative substitution of a pleasurable, superfluous and voluntary action for a serious, necessary, imperative and difficult one. At the cradle of play as well as of artistic activity there stood leisure, tedium entailed by increased spiritual mobility, a horror vacui, the need of letting forms no longer imprisoned move freely, of filling empty time with sequences of notes, empty space with sequences of form.
    Max J. Friedländer (1867–1958)
