Learning to walk again after an injury makes you appreciate stairs in a way nobody else can.

Things you never had to think about become visible the moment they stop being automatic. A flight of stairs stops being scenery and turns into a sequence of decisions, and getting up it becomes an actual event. That awareness does not leave when the ability comes back. It is one of the few things a hard recovery hands you to keep.

Notice one ordinary movement today that costs you nothing now and used to cost you something. And if you are in the middle of a recovery, you might measure in flights and doorways rather than in how far away normal still looks.
