I’m convinced you’re right. Consider how long your first road trip to a place feels, versus the 10th time you’ve taken that route. When you’re processing all new data, it stretches out.
Agreed completely. I don't think we perceive the passage of time at the macro scale. We perceive the acquisition of novel experiences and new memories.
I've had months of work I can barely remember, and three-day vacations that feel like a year's worth of memories.
