Page memory

I’ve noticed something clever that my brain seems to do. When I return to a book I’ve been reading, and open the book at the page I’ve marked, 90% of the time my eyes go right to the point I left off. I made no conscious effort to remember the paragraph I finished at, but somehow I know. Of course, the 10% of times I get it wrong mean that I have to check each and every time, to ensure I don’t miss a paragraph or two, but it’s still pretty cool.
