The thing I find most interesting (and confounding) is the vastly different reported death rates in different countries.
CV seems racist. The more Caucasian the country, the less deaths it seems. Is that just medical differences or is something else going on?
Universal poor air quality in cities, with 2.5 particulate index readings deep in the ‘don’t inhale’ category might play a part. Tobacco smoke on top of this background might just be a garnish of frosting.
