21 DNA-inspired double helix sculptures have appeared across London as part of Cancer Research UK’s campaign to raise awareness and funds for the Francis Crick Institute, a world-leading centre of biomedical research and innovation due to open in 2016.

This is part of a series of articles written by London Blue Badge Guides who used to be key workers in our capital city. First up is Neil Parker, who worked for 30 years as a postman before becoming a tourist guide. I qualified as a London Blue Badge Guide in 2013 and now, as my mates from the post would say, ‘I’m paid to be me!’ At least I was until March 2020 when Covid-19 arrived. This got me thinking, what was life like for my mates in the post? So, after it reopened, I went to the pub to find out.
