Heart attacks, diabetic complications, any of a host of other near-fatal conditions, just waiting for something to push it over the edge. If it wasn't COVID-1984, then it'd be something else, and if it was something else, the death would be recorded as having been from its true cause, rather than from the lesser cause that pushed the greater cause over the edge, if it had anything to do with the death in the first place.
It's well known and proven that the methodology used to count COVID-1984 deaths includes willful fraud in the form of counting deaths that were really from other causes, in order to massively exaggerate the COVID-1984 death counts. Anyone who claims that the official COVID-1984 death counts are anywhere close to accurate is either an idiot or a liar.
And even by the blatantly-fraudulent methods that have been in use so far, they still have not been able to pin a single death on the new Moronic variant.
