It was a miracle of science that permitted human beings to live, if not forever, then for a long, long time. Some people, anyway. The rich, the powerful--they lived their lives at the rate of one year every ten. Some created two societies: that of people who lived out their normal span and died, and those who slept away the decades, skipping over the intervening years and events. It allowed great plans to be put in motion. It allowed interstellar Empires to be built. It came near to destroying humanity.
