Stand 100% of the time...habit from my old draftman days I guess. Never could just sit down for very long (unless I was doing calcs and such). Had a nice revolving stool in my R/C shoproom but ended up taking it upstairs to use at my keyboard. However, it's interesting to note, that when I'm building plastic models or wooden ships (in another separate room) I do sit nearly all of the time. Must be ambibutterus [X(].

Soft landings.
