I came very close to it whilst watching Eastenders. However, I saved myself several months ago and used the 'off' button. Life has been good since, I'm so glad I did it.
There was a story doing the rounds a while back involving a film of someone sleeping. That's all the film was, just watching someone sleep, however at one point in the film the person sleeping turned over... and a man in the audience had a heart attact.
I think that's as close as I can think of to being bored to death!
