There were MANY of significant events in 2016. But our experience suggests that such events are typically spread over longer periods

Basically, your brain's memory system may be saying "What's happened since 2016... WOAH! That's a LOT. That must have occurred over a really long period, because that's how things work!"
I mean, it's *wrong*, but you can see the reasoning.
