JAFO !, ..... you got it !
Flying does come down to currency and attitude. If you don't fly for abit it costs nothing to mentally fly, revise, talk to your fellow pilots, bludge the odd ride, read anything saftey wise you can find, most flying schools/aero clubs now hold regular saftey seminars etc.
In the 10 years I spent Instructing the 2 worst type of pilot in every aspect where
1. Those who told anyone that would listen all the time what a bad Instructor they had.
2. Those Private Owners (not all) who knew all there was to know and by God there was nothing a young Instructor could ever teach them.
