I think that's a good idea and I have also read about this.
If I recall correctly, it was an article titled "sitting is the new smoking".
I had back surgery 18yrs ago. Sitting is definitely not something I can do for more than 10 minutes straight.
I read that article too. More recently, I read something about how just standing at your desk really isn't all that healthy either. It suggested that you need to move for 5 minutes after every 30 minutes of being in (more or less) the same position.
