Before GPS was printing off maps from google and before that were map books that you buy at gas stations. Navigating through a big city to somewhere tricky by yourself was no joke. It was a lot of memorization ahead of time and intense concentration to make sure you didn't miss key turns. We didn't just forget how to do something, it was never easy and I don't miss those days at all. I don't remember exactly how to do long division either but I do a lot more simple calculations now to figure things out than I did before. Saving mental energy is very real.
