Famous quotes containing the words signal and/or forms:
“Certainly the effort to remain unchanged, young, when the body gives so impressive a signal of change as the menopause, is gallant; but it is a stupid, self-sacrificial gallantry, better befitting a boy of twenty than a woman of forty-five or fifty. Let the athletes die young and laurel-crowned. Let the soldiers earn the Purple Hearts. Let women die old, white-crowned, with human hearts.”
—Ursula K. Le Guin (b. 1929)
“Your body must become familiar with its death—in all its possible forms and degrees—as a self-evident, imminent, and emotionally neutral step on the way towards the goal you have found worthy of your life.”
—Dag Hammarskjöld (1905–1961)
