Mid thirties, never had a license. We never had one growing up either. As my old man didn't agree to it either.
I gave up watching TV years ago because...well, it's a shite waste of time. I do get the odd letter through the door for 'the occupier', but that isn't my name so it goes straight in the recycling.
To be honest, I think a lot of the BBC's programming is very good but the way it's funded is bang out of order. Like a previous poster said, one shouldn't have to prove that you don't watch TV.
The company they use to collect the fee are bullies. I once caught one of their 'inspectors' in our living room when I lived in a shared student house years ago. According to the girl who opened the door (my housemate) this guy had just pushed her out of the way and barged into the house. Needless to say I unceremoniously ejected the scumbag
The easiest thing is just to ignore them. Save your time and effort whilst letting them waste theirs.
