Eli5: Why, if at all, does it seem like the years go quicker as you get older?

Question

I hear a lot of people making that remark, that the years go by quicker as you get older.
For me, at least, it seems like that’s only the case if nothing much changes in my life in that year.
To me, years seem to feel like they go slower if there’s lots of new/different things happening.

In relation to your entire life, every minute, hour, day, week, and year are each subsequently a smaller portion of your total life. They are the same length of time, but the longer you live, the less of the whole that length of time is in the grand scheme.
