The Cycle of Karma

When you're cycling around 100 miles a week through London, you develop some strange notions. The one I can't get out of my head is that you build up karma - good and bad - depending on how you cycle. So - if you stop at red lights, wait politely for pedestrians, smile at cars, you get rewarded - the next light turns green for you straight away, someone smiles back at you - you get the picture. Of course this doesn't always work, but it works often enough for me to try to cycle by those rules. Most of the time.
