On bikeback, there is a delightful sense of self-direction and autonomy. Lately, I have taken to cycling slowly, more fun than the fast, competitive commuter cycling I used to do. No longer do I jump lights or attempt that irritating wobbling thing that semi-professional cyclists like to indulge in.

When stuck years ago in a job I hated, my only friend was the public bench. As the tedious mornings dragged on, how I would long for the lunch hour, when I would be able to escape the torture of the office and stroll over to the churchyard and into the comforting wooden embrace of one of its benches.

These days we seem more bound to our bosses than ever before. We even identify our own selves with the jobs we do: 'What do you do?' is the first question we ask each other at parties, as if a job title could express a fundamental truth about our personality.

When walking, you see things that you miss in a motor car or on the train. You give your mind space to ponder.
