I keep them on nearly all the time, unless watching sports. We started when my son was a baby and have just kind of kept doing it. Now it is weird to watch TV without them on for whatever reason. But a personal complaint is when the words written don't match what is said. I get it with live TV, but for something that is recorded and the CCTV made for it, there really is not excuse. Netflix has a habit of doing this it seems.
