Is your posture correct? The usual ergonomic advice is to have the top of the screen level with your eyes, but I’ve found that to be less comfortable for me. I look all over the screen, but most often at the middle, so I want that level with my eyes. I don’t think that looking down all day is great for posture.
I’m not talking about office drama. I’m talking about getting cornered by someone in an alley on the way back to your car from a ballgame, or whatever. If you can’t run then you have two choices, you can fight, or be a victim. You’re fortunate that you’ve never been placed in a situation that would have allowed you to understand the statement.
