Do you live in your Office

Yes I sometimes feel as though I live in my office, I am in it for long hours at a time, more so than any other part of my house. Does anyone else spend as much time in the office?
In the corporate world we work set hours, here working for yourself, its all hours and more. How to get round it, you can't as you need to build your business on a continual basis. I can only think to take regular breaks and walks, out of the office, even a wander around the garden is a break, stretch your body, your arms and legs, move your head around a few times. If you have a laptop you can at least go into another room and sit and type, or even sit in the garden in the summer. Go make tea take regular breaks. That is one of the reasons why its good to make your office comfortable as you spend that much time in it. Make sure you have a comfortable chair, I sit on my office chair much more then i sit in the lounge. I spend far too much time in this office of mine.
