My thoughts exactly. I retired at 55. I’m 63, now, and learn new stuff, every day. I think one of the reasons that I learn as quickly as I do, is because I have an enormous baseline of experience on which to draw. I probably don’t pick up new stuff as quickly as I did when I was younger, but my baseline means that I already have a great deal of background to apply to new stuff, so I don’t need to re-learn a lot. TL;DR: I probably could “start from scratch,” a lot more easily, when I was younger, but I can “extend my knowledge,” a lot faster, these days.
