If I "blinked" when I was 40 (in the sense of not paying much attention to what was happening over what felt like a not particularly long period of time), maybe a week would go by.
Now, it's months. Or maybe it's an effect closer to memory "time compression". When I was 40, 6 months of memories was quite a distinct cluster of different things. Now, 6 months of memories is closer to one memory. It's not precisely like that, and certainly not all the time, but that's a handwaving general description of how I perceive things these days.
