"Put yourself into the 1980's. You are 25 years older. Behind you has swept an era of scientific achievement unequalled in history. Population has soared. New countries and new civilizations have sprung up. Time and distance have shrunk to the point where they mean almost nothing. Frontiers of outer space have been breached, the infinite universe has been challenged. The ferment of the world has been matched only by the upheaval that has taken place in your own life. In a single generation your living standards have risen to levels that make people refer to the 1950's as "old-fashioned."
