Hi @DrDonaLocke ! For me, bike rides are key. I think it isn't just the exercise but also being outside in nature. There is one point on my ride where I hit a trail through the preserve, and there is almost a "click" or "ahhhh" that goes off in my brain as I round that curve. I also find playing solitaire on my tablet after the kids are in bed helpful. Spider solitaire is just challenging enough to engage my brain to stop thinking about other stuff, but not too entertaining like other computer games or tv shows. Thanks for posting this!
