Why not both? (Score 1)

I got tired of sitting for long periods of time years ago and made myself a stand-up desk. Now I work at both a regular sit down desk and my stand-up desk. I just swivel the monitor and have an extra keyboard and like to change back and forth as it suits me. Sitting is much worse for circulation than standing in my experience. I have been told by those in the know that standing and moving around while you work helps the legs return blood to the heart. Just my two cents.
