You may be the minority at least, but you also have to see it as having options. There's a big difference between having a room with a window and opting to close the curtains, and have no window at all. Most likely you also don't get depressed by working in a bright room, while others actually suffer if they have to little light.

I would guess that all Scandinavia countries have similar rules, and there's actually a minimum amount of light you're legally allowed to have in a room. The law in Denmark for instance actually require a room to be insanely bright.
