I agree Alan. In the 70s I lived in Broken Hill, we had every type of club and sport imaginable. Sailing, gliding, GA flying, rallying, motorbike racing and many more. We all worked to the mine whistles and had ample leisure time. When I was on the staff we rarely worked overtime, never weekends, and when I was a union man the hours were 8am to 3pm day shift, etc. Flying and training was about the same cost relatively as now. My flying fell off due to costs of a growing family and more work committments when I moved to Victoria. It became intermittent for many years and I only got back into it with AUF and RAA in the 90s, then back into GA after retirement.
My five children have all worked much harder than I did in my first ten years in the workforce, though probably not as consistently hard as I did later on. I don't think they would have the time to commit to flying frequently enough to stay safe. That was a big consideration for me, that I could only fly every six or eight weeks and was usually really tired when the weekend came along, I just didnt feel safe flying and used to get anxious the night before.
