I don't buy the "novelty" thing, either. Between high school and an evening job, about three of those years were the most regimented of my life, and high school definitely wasn't providing enough novelty, in any way, to make up for it. Yet those years felt extremely slow compared to now. I feel like I blink and a season's gone. Fall or Summer used to feel so long back then. And Winter, practically eternal. Now it's like, "wait, didn't Summer just start? Why are the leaves all turning?"
Some time around IIRC 25, the effect really started to take off, and it's never gotten better, no matter how much my life is shaken up.
[EDIT] and on shorter time scales, back then, tell me I've got an hour? Fuck yeah! Enough time to do several things! Now it's like... ugh, barely enough to even start something. Guess I'll putter and tidy the house until it's up, which'll feel like about ten minutes from now.
Another way to look at it: by the time you graduate high school, you will have spent 1/4 of your life there. By the time you are 40, 10 years is 1/4 of your life. By the time you are 80, 20 years is 1/4 of your life.
The relative portions of your life get longer the longer you live.
That's another way to look at it, sure, but it still doesn't seem to explain anything about why perception of time speeds up with age. That's true, but why does it matter?
