Well, that is not the full story though...
I expect older people to watch more TV. All my grand parents basically sit in front of the TV all day... I would expect I would watch a lot more if I was older currently, even simply because I would have a lot more free time.
As an older guy I can assure you personally that when I have free time, the last thing I want to do with it is watch TV. Too much living to do.
I do agree with your observation about old people and TV in that my experience with elderly ancestors is an extremely high correlation between watching TV all day and death within the next couple years. When you can't do anything anymore physically but open your eyes, the socially accepted dumping ground (at least on a small scale) is in front of a TV. I believe this explains the peculiar claim that 80 year old people "watch" 16 hours per day of TV on average. This does not explain the claims about 50 year olds.
Maybe I'm a contrarian or I see lot of this here on HN for what it is but I find these comments funny and ironic. How do you find time to comment HN with all ths living to do?
By not watching TV, LOL. Supposedly in my age bracket, at least according to ad sales folks trying to peddle their time, its saving me on average 10 hours per day or some bogosity like that.
That's what I mean about bogus stats. I never power my phone off (why would I?) and its got 3G internet everywhere I go, therefore on the graph by the same logic I have 24 hours of mobile use per day.
