" We all have that magic bank account: it’s time! A big account, filled with fleeting seconds. Every morning when we wake up, our account for the day is credited with eighty-six thousand four hundred seconds, and when we go to sleep every night, there’s no carryover into the next day. What hasn’t been lived during the day is lost; yesterday has vanished. Every morning the magic begins again, with a new line of credit of eighty-six thousand four hundred seconds. And don’t forget rule number two: the bank can close our account at any time, and without any warning. At any moment, life can end. "
