> 1.44 MB pretty much fits in my head.
That the size of a zipped plain text bible.
There are some people that knows the bible by heart, and I suppose if you work with it a lot, you have a general idea of the order of all things, and what's going on in each part without having to know the exact words. Like an essay you've been working on for months.
So seems about right.
Maybe it's time for a new metric: 1 floppy is what you can hold. More is too much.
