I love walking at night. The darkness shrouds everything in an enchanting mystery. Trudging along the near deserted streets, accompanied only by the dull, rhythmic thuds of our feet, the darkness, the simplicity of what we are doing humbles us. We're equal. The most coveted celebrity is indistinguishable from the poorest soul, just a solitary figure under the street lamps. Reading the Observer 'Walk Yourself Fit' booklet I discovered Alexei Sayle shares my views on this. Apparently, Rousseau, a philosopher whose ideas were crucial during the French Revolution, wrote 'Reveries of the Solitary Walker' just from his thoughts whilst walking.
