I'm so old that I did those same things along with riding my bike without a helmet and knee pads, being able to walk anywhere without having to be afraid I'd be picked up by some pervert or worse, didn't have to lock the doors or have alarm systems to set when we went somewhere, and ate home cooked meals more than fast foods.
I never had fast food until I was an adult... not that it wasn't available, but it never occurred to me to want it ..
