It isn’t that we have no lights. We do. They’re on most of the time. The walls are painted black and there are no windows, because occasionally we want the lab to be dark so we can simulate the lighting conditions of space. We have a spotlight that approximates the brightness of the sun for when we do those tests.

The end result of this is that, especially in the winter, it’s really easy for me to drive to work in daylight, and then that’s literally the only time I see the sun. I leave work after dark. Totally screws with my circadian rhythm.
