Ever found yourself in a situation and wondered how on earth you got there? It was a thought that occurred to me as I clung to an indoor climbing wall recently, muscles shaking with the strain and unable to move my arm to the next handhold.
I wasn't sure whether I'd mentally frozen or I was physically incapable, but either way, I came to a grinding halt. I was mid-way on the wall but might as well be at the top because I can’t just lower myself back down.
