We often find that as we get older, time seems to go by faster and faster. The effect is subtle at first, but before you know it, you realize that it's been over 20 years since people were worried about the Y2K computer bug.
And it's not just the big moments we actually lived through that feel like they happened later or earlier than they should have. Hindsight has a way of making history seem a lot neater and more orderly than it actually is and it's easy to forget that the experience of living in one place in 1975 (for example) was vastly different from how it felt to live in another.
And that's why the facts I'm about to share with you "feel wrong" even though they're quite accurate.
