Like you, I've been busy aging.
My days now seem to go by as quickly as the hours of my youth. Have you ever watched a timer counting down to zero? I'm pretty sure the digits change faster now than they used to. It's haunting to imagine the last year of your life passing as fast as the day you were born.
If time really is accelerating, or, at least, our perception of it, then ought we give any meaning to our measurement of it? It might be more prudent to ignore the whims of our clocks and calendars and to realize the futility of our compulsive time-tracking.
This moment is one in a series of moments that will end in death. Within every moment is a lifetime of possibility. Every lifetime is a mere moment in the expanse of the cosmos. Let's cease ours.
