I do end my days in a state of tidy closure and everything gets shut down and turned off. I suppose it depends on the sort of job, I'm tidy haired management these days, so I merely create order from the chaos below and distil it into something that makes our fleet commander happy. If there's something ongoing, it's usually in my head. I may occasionally scribble a few notes about tasks to finish off. I'm strict about work and personal life, so off is off.
