I count things…
As I go through my day I am just about always counting something. My footsteps, the number of steps in a staircase, how many trees I drive past… something.
I do absolutely nothing with this information, it is discarded immediately, it is of no use to me in any way whatsoever. Most of the time I barely notice I am doing it until I hit a number that strikes me as interesting for a fleeting moment. Being asked what number I was on would probably cause it to evaporate.
Brains are weird.
