If you mean the computer safety rule that says engage brain before engaging computer, well,,,, sorry,,,, I keep forgetting that one. And the computer company didn't put a warning label on the computer either about that or the surgeon general's warning that using it is hazardous to your work and sleep habits.(of course the website doesn't carry the surgeon general's warning about reading all caps either) I do have glasses on in case the monitor blows up. The floor is a non-skid surface (carpet). Got my rabies shot too in case the mouse bites me. Got a mousetrap set up to catch that little devil but it don't like the spray cheese I put on it. I was going to bed but found a john wayne movie on. catch you later.
