To be so assured of food supply that we can stop counting down to the harvest, or to the new spring.
To be so assured of health that death is too far away to bother counting.
To be so assured of philosophy or religion that even if we can't make our days infinite, we are not bothered by their end.
To be so assured of loved one's safety that we are not counting the days until they return.
To be so assured of peace that we are not counting down to the next war.
It would be a damned lie to say we were anywhere near this end of counts before The Event. But we were hopeful. Telepresence, micro-factories, nano-vac - we seemed to be getting the wants and safety covered, even if there were so many philosophies and conflicts that allowed for a deeper reassurance. Well, maybe it was only for a select few and we were living in a cyberpunk future. Then again, the world was cyberpunk ever since they installed metal detectors at O'Hare Airport and we accepted the reality that unattended luggage would be take away and detonated. Turbojets didn't transform the masses into the glamorous "Jet Set" - they became cattle in aluminum tubes instead.
It shouldn't take an Apocalypse to make you grateful for what you had. Then again, even that didn't work, and there are still people craving more and seeking We're always going to be petty and competitive, and neither the undead or aliens are going to change it.
You can count on that.
