"Smoking has gone out. To be sure, it is a shocking thing, blowing smoke out of our mouths into other people's mouths, eyes, and noses, and having the same thing done to us. Yet I cannot account, why a thing which requires so little exertion, and yet preserves the mind from total vacuity, should have gone out. Every man has something by which he calms himself: beating with his feet, or so."

Samuel Johnson, quoted in Boswell's *Tour of the Hebrides", entry for August 19.
