I don't know if you have kids, but looking after them (some kids more than others) can be an utterly exhausting task that starts at dawn and doesn't end until 8:00pm. Television turns out to be something that can occupy some of the most hyperactive kids with minimal supervision.
If you asked any worker "why does there have to be a lunch break" they'd look at you like you were insane. I think the same applies here.
