Famous quotes containing the words free, guard and/or zone:
“I wish more and more that health were studied half as much as disease is. Why, with all the endowment of research against cancer is no study made of those who are free from cancer? Why not inquire what foods they eat, what habits of body and mind they cultivate? And why never study animals in health and natural surroundings? why always sickened and in an environment of strangeness and artificiality?”
—Sarah N. Cleghorn (1976–1959)
“Those who guard their mouths preserve their lives; those who open wide their lips come to ruin.”
—Bible: Hebrew, Proverbs 13:3.
“The human race is a zone of living things that should be defined by tracing its confines.”
—Italo Calvino (1923–1985)
