Unless you're in flow. That is the only time I sit for any extended period - when I am so engrossed in what I am doing that I don't notice the time. Normally I get up and walk around every ten to twenty minutes, I'm a little hyperactive and usually need to do something active fairly frequently. And unfortunately, libraries don't work for me, I find other people much too distracting.
