I do this as well. I guess I should elaborate on my 8-12 hour days. It's rare now that I will sit in the chair for more than an hour at a time. Not only due to my awareness of the issues that it causes, but also because it just helps me clear my head to get up and go talk to some people, walk around the office, etc...

This should be done if you have a standing desk as well.

Clearing your head is important. Unfortunately, many people seem to forget that it is necessary. "The physiological effects of tiredness are well-known. You can turn a smart person into an idiot just by overworking him"[1].

Also: Getting out the door is good: Five minutes of "green exercise" turns out to be good for your mental health[2].
