We go up and down stairs every day and yet we barely remember our experiences doing so. amirite?

But you also open doors, get in your car, sit down at your desk, etc. and you don't remember any of those either

I fell down the stairs yesterday and have a bruise across my ass. I remembered that experience vividly

What is there to remember?

I fell up the stairs two years ago. I remember it. It haunts me.
