I stole the title from this article:

I’m rubbish at keeping a note book. Mostly because I can’t read my own hand writing and my spelling is comical. On the other hand I was recently flicking thought old sketch books and I could tell you exactly what was going on when I drew that picture. Right down to where I was when I drew it.

I bet that would make an amazing study on the memory of artists or even art students. I do love a bit of visual sociology!
