Is so vanilla
Also, it has to be said, the impact of alcohol (and illegal drugs) on life expectancy in those former industrial cities.Not to mention other manufacturing industries especially steelmakers and iron forged, plus coal mining. Coal contains heavy metals, radioactive isotopes and mercury to name but a few. And Glasgow was a home to chemical manufacturers for a long time. The high flats at Sighthill were built by Cruden on a large chemical waste site.
And where were these places? Largely in communities that were affected by poverty when the employer was no more. Places like Pollok, home to the Saracen foundry and decorative ironworks, or Parkhead where one of the largest forge's in Europe was. Patrick was home to a number of boilermakers (for ships and steam engines) as well as shipbuilders at Pointhouse on the north side of the Clyde.
Collieries of all grades and sizes were throughout the city, and whilst some like beneath Glasgow uni were worked out fairly early on, others towards the east of the city were not.
When people breathe in the byproducts of these industries it's no surprise that life expectancy decreases, and even now we're seeing the legacies of heavy industries across the city. Poverty only makes it worse.
