h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

Hi,

I am greaty impressed by your knowledge of page turning.

I would like to ask your opinion on the following phenomenon; Why is it that, as a right handed person, I find it easier to flip from the back of a book toward the front, while my girlfriend, who is left-handed finds the opposite to be the case?

Surely, even as a right handed person, I was trained to read from front to back? This habit of mine makes no sense and I feel the need to harm myself every time I catch myself doing it. Please help!
