I can not explain it, but the older I get, the faster the time goes by.
The longer you’ve been here, the less a day, month or year represents on a percentage basis of the world you’ve experienced. They literally are shorter in your perception. Summer days as a child went on seemingly forever because they did loom large compared to the sum total of your experience up to that point. My late grandmother said at age 90, that it seemed to her that she awoke and just couldn’t grab hold of the day, then it was gone.
No kidding. September 1st was just yesterday, right? Don’t blink, or tomorrow will be Christmas Eve.
