Famous quotes containing the word active:
“I am grown old and my memory is not as active as it used to be. When I was younger I could remember anything, whether it had happened or not; but my faculties are decaying now, and soon I shall be so I cannot remember any but the things that never happened. It is sad to go to pieces like this, but we all have to do it.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
