@Gargron +1 I hit peak digital a while back and now my goal is to do as much as possible in the analog world without terribly inconveniencing myself.
Our car has a key fob which the car senses when you get close and it lets you open the doors, start the engine etc. Except that the battery runs down every two months (or so it feels) and I'm constantly carrying the cognitive load of "must replace battery". So I've mostly gone back to using the physical key, which works at all times.
