Once upon a time it was normal to adjust the location of the desk to the person working there. If lefthander, place table towards the left wall with light coming from window on the right. If righthander, place to the right of window. The typewriter was placed on a small table in front of the window. When the computer showed up, it was first placed in the corner toward the window or in front of the window but the later location proved hard on the eyes so we stopped with that. What has changed now that we stopped with this practice? I thougt we would have the office layout perfected by now?
