My friend was a Grandmother at 48 and she kept quiet about about it as she also found she was being judged as too old for things she still liked to do.
As to the Archers I still listen occasionally, but it seems to me there are plenty on GN who listen regularly but knitters or people like me who have knitted so many garments that I'm quite an expert, don't appear much on GN.
Bye the way knitting is being Creative and whilst knitting most of us do something else like watch TV or listen to the radio and I also think a lot when knitting, the hands moving and the brain being constantly engaged in THINK mode.
Perhaps some on Mumsnet should try it.
