In 1910, the average adult was still sleeping nine to ten hours a night. Now the average adult is lucky to get a full seven hours a night. Most of us don’t. Those numbers add up to an extra five hundred waking hours a year. In nature, we would sleep 4,370 hours out of a possible 8,760, or half of our lives. Eighty years ago, we were down to 3,395 hours. Now we are lucky to get a measly 2,555. If nature keeps score, and we bet she does, that means we only get to live about half as long. We may have doubled that figure with surgery and antibiotics, but think how long we could live if we slept, too.
