Morning All - went for my usual 6am fast-walk today (useless at running). It's become a habit since the lockdown. And the London Hum is back. You can hear the background drone of the traffic clearly again. It reminded me of this article from the Guardian last year about city noise. https://www.theguardian.com/cities/2019/mar/16/can-you-hear-the-mysterious-global-hum-apparently-many-of-you-do I wonder what will change, if we / I will change my ways .... views welcomed :-)
