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.

When you are 10 years old 2 years is 20% of your life. But at 50 2 years is only 4% of your lived experience. The comparison of time passing vs time passed overall makes it feel insignificant
