Is it just me, or is everyone much better at intensive tasks when sitting in a chair compared to lying down? Something I've noticed over the years - doing homework while lying on my couch/bed is significantly less productive compared to when I sit at my desk. It's not just for when I'm on the computer either - when I play NHL 11 and I lean back comfortably, I can't play worth a damn. Once I lean forward though, it's on. I figure the comfort just does not allow you to concentrate as much, but if someone had a more scientific reason, I would like to hear it :)
