A billion seconds is more than 31 years

Human brains are famously terrible at comprehending large numbers, and the difference between a million and a billion proves it perfectly. If you wait a million seconds, you will be waiting just about 11 and a half days. But if you try to sit around for a billion seconds, you will be waiting exactly 31.7 years. Next time a billionaire tells you they worked a thousand times harder than a millionaire, do the math.
