Well, I wish I could say the same. I am a general contractor and I did some work for the UC Medical Center in San Francisco. I was hired to remove a door, frame up the opening, drywall and finish it so that they could out up a mural. I had to set up late at night and I thought I would be alone. I got out my sawzall and began cutting out the matal frame from the door. After a few minutes a gaggle of eye doctors, yes I was working in opthamology, came around the corner. They all kept walking, so I thought I wouldn't hear it, but then one of them came back and gave me the lecture on what could happen when you don't wear your safety goggles.
I still haven't learned.
