Hey hayden snap i'm 20 too, I did grow up with sunday morning re-runs of Dr Who on UK Gold (and blake's 7 too)
Reccomendtions, only one i can give is if you like the original hitchickers tv show, you'll like the original Dr Who as they share many things.
Oh and did i tell anyone i met Tom Baker and got him to sign a copy of Genesis of the Daleks? :P
