If you have ever met me in person I have a hard time sitting down for too long. I'm generally a relaxed person, except when it comes to movement. I'm always walking around the office at a fast pace and I tend to walk everywhere for hours at a time. Whether I'm traveling or exploring Brooklyn on foot, I'm always on the move. I have a hard time sitting through a long movie like "Boyhood", or taking a plane when I can't get up and walk up and down the aisle a few times or stand in the back galley chatting with the crew. I think you get the point, I have the natural inclination to not sit too much and I think that it's healthy, but I'm always looking for ways to improve.
If you have been following the evidence and research about sitting and the latest trends for standing desks, you might also think twice about sitting all day and mix up the types of chairs you sit on and how often you sit. Instead of trying to grab a seat on the bus or subway, stand, instead of having a long meeting sitting have a standing meeting. Set your computer's printer on the other side of the office, switch your favorite chair once in a while or sit on the floor.... so many possibilities...
