These are very good. I take phone-free walks around the neighborhood, to the store, downtown for a festival. It feels weird at first, then it's nice.
I took an internet-free vacation last spring, and it was lovely.
While planning the trip, I made sure my old TomTom's built-in maps seemed accurate to what I was seeing online; there wasn't a lot of road-building activity there in the last decade or two. Then I turned off my phone and locked it in the glovebox, there in case of emergency.
Then I took a deep breath, started the car, and headed north.
It was awesome just knowing there was no way a notification could ding, nobody could call me, no news headline could pop up and harsh my mellow. Even if those things didn't actually happen constantly, simply existing in a state where they could was stressful, apparently, and turning the damn thing off was remarkably cathartic.
