i "work" in a control room at a small powerhouse.once the equipment is all up and running, i fall into moniter mode untill an outage or upset occurs. i'm in a room for 10 1/2 out of 12 hours. my eyes are constantly glancing at the various moniter screens, but i'm also on here at the same time for maybe 9 hours or so. i have dial up at home, so if i'm not working, i'm not surfing.
