After a long day at work, I find I need certain cues to tell my brain to cut it out and think about other things for a while. Sometimes it's a tasty beverage (be it beer, coffee, or otherwise), a long walk, or turning up a favourite album really loud.

I think this is the same for any individual whose job requires that you live in your head for a long time. I'm fairly certain artists who are deeply involved in their work experience this "surfacing", as I've come to call it.
