You know, this is exactly what my Dad did. He's in his late 80's now, and retired back in '92. He job kept him busy 24/7 for most of his career, and he never had the time to watch TV, when there were so many other, more important things to do.

Nowadays, he uses my Netflix account waaaay more than I do. And he's catching up on decades of shows, and quite enjoying himself. He just finished Season 3 of ST:TNG. It's been fun talking to him about episodes I watched back in the day, too.
