some executives never stop working, even when not on site they consider time spent solving problems in their head or sitting at their computer/tablet/etc as work.

myself I have been around some six to six executives who even at parties talk shop. hell we used to joke that when one went on vacation it only made his emails longer

Yes, I'm sure they do and I would too but that is not the vernacular "working".
