Pretty sure any journalist who cared to look could find someone to share that sort of "opinion" in any part of Scotland they cared to seek it in, not only Glasgow and the West.
@laidback
as you say, for parts of the west central belt life expectancy is lower. 73/78 years in Glasgow City (male/female).
Scot av is 77/81. UK av 79/83.
Poor health + CV-19 and outcomes are bound to be worse.
And that's overall - see this absolutely grim stat from less than a decade ago: "There are wide geographic (and socio-economic) health inequalities exemplified by a 15 year gap in male life expectancy at birth across Glasgow’s neighbourhoods and an equivalent 11 year gap in female life expectancy (in the period 2008-12)" (source: https://www.understandingglasgow.com/indicators/health/overview)
I am not inclined to blame the feckless poor for their sufferings, Victorian (or Tory) style...
