I tripped going up the stairs a couple weeks ago, and have lost all confidence in this maneuver.
I can no longer race up the stairs two at a time. I think about each move I'm making, and pause before making the next one.
It's an absolutely bizarre feeling. How long will it take for me to forget about my spill, and trust my body again? Once again, a reason why a bad memory is one of the greatest gifts God has given humanity. And what a timely day to think about this.
