Murray, I can relate to that. When I was in the USAF in AK in the 70s I worked on classified electronics. Not a big deal but we worked in a building that did not have windows. In the winter I'd go to work in the dark and go home in the dark. If I didn't go outside for lunch I'd never have seen the sun. It came up around 10:00 and went down about 1:30 - 2:00. I got used to it. It drove my wife nuts.
