Many people I meet express surprise and puzzlement: what do I do with all that time? how do I keep in touch with current affairs? (By reading The Independent, obviously).
In my two years of not watching the Devil's Picture Box I have visited places and seen things I never would have had the time to otherwise; yes, read more books; resumed the guitar; studied calligraphy; learnt to draw and to play Go; spent many happy hours reading and writing correspondence with friends in this and other countries; and many other things. There's no Da Vincian conceit here: I don't do any of these things at all well: just at all.
Chickens may like television (actually, according to the researchers involved, they like watching screen savers - flying toasters a favourite), but other studies show that humans watching television eventually have their metabolisms depressed below the level of someone doing absolutely nothing at all. I don't see the advantage.
