Many people, when they come home from a long day at work, sit down in front of the TV to unwind. It is, for example, what my wife is doing right now.
I came home today from a long day at work where I spent several hours staring intently at a TV, turning aside only occasionally to make some adjustment or other to various video settings. The thought of coming home and sitting in front of a TV isn't all that appealing at this very moment.
This happens a lot with test content, too. There are some video clips that I've seen so many times that I can practically see them in my sleep. Years ago, I worked on the QuickTime team at Apple, where I saw the music video to Sarah McLachlan's "Building A Mystery" innumerable times. Even now, when I hear that song on the radio, I can see each frame of the video in my head -- including the compression artifacts of the video codec we were using at the time.
