Sir, - I am encouraged that the taxi drivers seem to be prepared to return to work, albeit still under protest. However I feel some sense of regret. Over the past weeks I have out of necessity walked more, so I feel healthier: and I have taken more buses, so I feel less of a burden on the environment. I wonder how quickly I will - or indeed should - return to my old habits. - Yours, etc.,
