Oooh no Harvey I too listen to a lot of discusssion on radio 4 while working through my mobile phone with earphones attached, being a bit of an information junky myself like you I like to hear a well informed topic its good to listen to a enthusiastic expert on a given subject , Always interested in the Countryside articles with Music and History a close second, not having had the pleasure of a good education
I have learned so much from these programes and also like to keep up with World affairs.
This has all come about as I have got older but I have always had a interest in social affiars and documentaries, a bit like Alice Cooper playing Golf in the 70's but not letting on for fear of a broken image, now I can engage and enjoy it without feeling like a anorak,so no you are not alone there is a big world out there with so much of interest in it.
