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:
“If youth is the period of hero-worship, so also is it true that hero-worship, more than anything else, perhaps, gives one the sense of youth. To admire, to expand one’s self, to forget the rut, to have a sense of newness and life and hope, is to feel young at any time of life.”
—Charles Horton Cooley (1864–1929)
“As the two boys walked sorrowing along, they made a new compact to stand by each other and be brothers and never separate till death relieved them of their troubles. Then they began to lay their plans. Joe was for being a hermit, and living on crusts in a remote cave, and dying, some time, of cold, and want, and grief; but after listening to Tom, he conceded that there were some conspicuous advantages about a life of crime, and so he consented to be a pirate.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“Take care! Be on your guard against all kinds of greed; for one’s life does not consist in the abundance of possessions.”
—Bible: New Testament, Luke 12:15.
