I guess most people, like me, cannonball their way from the womb toward the zenith of biological flight, before suddenly feeling that jump in their gut telling them that the elevator is going down. What makes it so holy-moly shocking is that the 40 years suddenly seems like no time at all - we were just getting started!... and all we have left is perhaps another forty. A puny, if you're lucky, eighty years. Just enough time to awaken to the grand visage of the world, wonder at it, get hurt by it, discover that you can mumble at it and get some responses, find another like you who desires to spend some of that time with you, learn how to manipulate objects within that world so as to gather more objects from that world, perhaps glimpse for moment welcoming yet another like you into this world, look back and wonder what all the awakening was about, run down, and disappear.
