I climbed over a gate yesterday. Twice. It was about the height of my chest and had no bars to use as foot-rests, so I hauled myself up using the strength of my arms. I didn't need to do it; I could have got to where I was going another way; but I wanted to prove I still could. When I reached the top I wobbled a bit and could easily have toppled over and cracked my head. There was no-one watching so I wasn't showing off- except to myself.
