Life
Life (cf. biota) is a characteristic that distinguishes objects that have signaling and self-sustaining processes from those that do not, either because such functions have ceased (death), or else because they lack such functions and are classified as inanimate. Biology is the science concerned with the study of life.

Famous quotes containing the word life:
“... the hey-day of a woman’s life is on the shady side of fifty, when the vital forces heretofore expended in other ways are garnered in the brain, when their thoughts and sentiments flow out in broader channels, when philanthropy takes the place of family selfishness, and when from the depths of poverty and suffering the wail of humanity grows as pathetic to their ears as once was the cry of their own children.”
—Elizabeth Cady Stanton (1815–1902)
“When life has been well spent, age is a loss of what it can well spare,—muscular strength, organic instincts, gross bulk, and works that belong to these. But the central wisdom, which was old in infancy, is young in fourscore years, and dropping off obstructions, leaves in happy subjects the mind purified and wise.”
—Ralph Waldo Emerson (1803–1882)
“Neither a life of anarchy nor one beneath a despot should you praise; to all that lies in the middle a god has given excellence.”
—Aeschylus (525–456 B.C.)
