I am intrigued by cultural attitudes to television.
Quite a lot of people appear to view it as an addicition similar to heroin, and that 'giving it up' is similarly traumatic, and worthy of public admiration.
Others view 'giving up' television as desireable and noble - rather like giving up smoking, and take a similarly moralistic tone with those who still 'rot their brains' with the devil's box.
I personally adore television and have for as long as i can remember. I find a huge amount of enjoyment and education is to be had, but like all cultural offerings, the viewer needs to be selective and use their time wisely. Thanks to digi-boxes and dvd's, it's possible to keep track of all good programmes, and to walow in nostalgia as well.
My current lunch hour includes eating my sandwiches and working my way through two boxed sets of 'Callan' - which looks very dated, but I can remember how cutting-edge it was at the time - a 'hard man agent' who admitted to being scared on a regular basis.
So I make no apology for being a lover of TV - i could give it up, but i could give up chocolate as well, and why would i want to - both give me great pleasure, and life is to be lived and enjoyed.
If you feel you don't wish to watch TV every evening, there are dozens of things to do - as others have indicated - just try not to feel smug or self-righteous in any way - such feelings are inappropriate, no-one visits a higher intellectual plain simply by choosing not to avail themselves of a television.
