Few people are in a job where they can't walk around the office every hour or so. Go get some green tea from the coffee room, stand at a window in an empty meeting room and stare into the distance thinking about a better way to solve the problem you are working on.

Banging away in long coding sessions is a good way to create tons of subtle bugs that are hard to find because you did too much coding before running all tests and having a code review.
