The thousand yard stare. I used to get it playing vidoe games too much now that those are a no no I think at work I get it from looking at the monitor too long. In my office it's probably unnoticed but I'll snap out of it and sometimes it's been 5 minutes or so. At home it's hard to say I think I tend to close my eyes and drift off more than I used to though I don't really fall asleep. It's funny though, I even stop hearing the tube. Generally I think it's my melon saying "break time" we'll get back to you shortly.
