Does Ceiling Height Make Me Antsy at Work?

I saw this on Kottke the other day and it got me thinking about my office. The thesis is that ceiling heights affect a person’s thoughts, creativity, and emotions.
My job, while perhaps the most creative at my employer, is still a bit stifling for me. I get to explore, but only within a tightly limited sphere. Contrast that with my physical office, which is an open work-group style space (no cubicles, yay!) with 18-20 foot ceilings. Is my mind subconsciously rebelling against the boundaries of my job because the ceilings are so high? Hmmm…improbable but a fun explanation.
