|This isn't my old cubicle but it sure looks like it. Minus the windows.|
Most of my claywork is done indoors also, eight months out of the year, but I am rarely inside for more than three straight working hours. I walk to the store, I go check the mail, I stand on the deck and watch the birds at the feeder. (Ha, and I thought I just lacked discipline.) Some jobs - waxing, sometimes glazing, loading, firing, kiln maintenance - are outdoor work. Maybe my more interesting thoughts are a sign of a better-functioning brain!
Wherever you work, take a break and get outside! Your brain will reward you.
