Which side of the bed do you sleep on?

Let’s say you’re standing at the foot of the bed and facing the bed, which side is yours?

Do you stay on that side or do you travel all over the place once you’ve fallen asleep?

I ask because I recently heard that there was a study done, and it claimed that the majority of married women sleep on the right side of the bed. It applies to all of the married women that I know personally (myself included.. though I’m one to wander once I’m zonked out) so now I’m curious.
