How do you take a day off when you work from home?

Both Brian and I are at home sick with the flu. Brian at least gets to leave his work environment and take refuge in the comforts of home. I, on the other hand, keep looking at my laptop knowing that I have a magazine article to write. I told the editor I would have it to him by next week and I haven't written a word. I haven't even started my research. Maybe I could change the subject from crossover vehicles to "Are double toilet rolls really two rolls in one?" Because, between you and me, I really don't think they are.
