Are you one of those people with encyclopedic mind? If you have a special interest or obsession, do you know everything about the subject.
I'm not one of those people. I had pretty good memory until age of 6. Then I started noticing that I couldn't remember things as well anymore. Later I could only remember things I could visualize in 2D. That's why geometry and biology were my favorite subjects. And yes I could find a way to imagine... let's say a human body and how it works in 2D...
but I've always been fascinated by people who can remember dates, names and events. or by people who have photographic memory. or folks who know everything about space... have no clue why, for me it's like this - space - 3D - no can do I'm wondering if it comes sort of naturally or they still have to put some effort into remembering all those things.
How about you?
