Thanks for all the replies anyway, I guessed I'd be opening up a can of worms with this thread.
I'll try a quick summing up here.
Volunteering: Interesting
Cleaning Purples House: Not so interesting, but appreciate the sense of humour
Part-time courses: Interesting if cheap
Clubmans wrist exercise: Could do myself an injury, addictive personality and all that..
Xaviers wrist exercise: Rehabilitation from Clubmans suggestion
Library & Ray D'arcy: I'm not a reader and poor old Ray is off on Paternity so have to listen to AMK instead (not a fan, already endure her morning show on the way to work)
Take up a musical instrument: You'd just have to see me dancing to believe just how much of a non-runner that is
Child minding for TarfHead: I'm starting to notice a bit of a trend here from female posters...
Woodworking: Interesting but wouldn't even know where to start..
And really I don't think anyone wants my job.. I get paid too much to do too little 3 or 4 days a week..(I do have to work Sundays, that's the tradeoff) Mind numbingly boring..
