I'm resurrecting an old bicycle and was cycling around on Sunday in the hilly area in which I reside.
I was taking lung fulls of air, depleting the oxygen and puffing out carbon dioxide rich exhaust.
Meanwhile kids on their green electric scooters came silently past me no doubt patting themselves on the back at how eco friendly they were.
It was then that I realised I'm just a dirty old man and the world is in safe hands.
