DJ, I don't see why speaking of asbestos is not nice. it was a fact that in the 70's asbestos was prevalent in our food and drink. Asbestos pulp was used as a filtering agent in the food industry and us and our children would have ingested it without any knowledge of it. This is a different issue to the asbestos industry and it's dangers, which were known, if ignored.
We discuss the dangers of man made chemicals etc. yet asbestos, a natural material, has proven far more dangerous than many of those chemicals and is still a major danger as so much still exists. To not speak of it and it's dangers would be ignoring it.
To think that London, or anywhere else for that matter, does not belong to any one demographic
