I actually think in pictures a lot and all the aptitude tests I've done come back as I'm very visual and very logical. I'm also very good at remembering things like phone numbers, a useless skill now with phones that can remember numbers, which was something I didn't realise till in my 20's when I shared an office with a guy who had a pin board with business cards near my desk and he would ask me for different numbers until one day he said "Wow, you are not even looking at the cards". I think there are all sorts of memory types and mine is not photographic, but more like a video tape that is recording and playing in the background, as I can be at work and think, "you know what I didn't turn the light off in the garage when I left this morning" and when I get back home I'll find it on. I can also visualise projects in my head and problem shoot them before I even start on them physically, thinking things like, "if I do that, that piece will hit the other piece so I'll have to make it smaller, but then the screw won't be able to go in from that side, so will have to go the other way round" etc. I can also find my way back to places I've only been once, or look at a map and remember how to get there without looking at the map again, another useless skill now with GPS.
