For what it's worth, this matches my own experience.
As I've said many times, any individual one of the 'sudden and unexpected' deaths and diagnosis I've seen in my wider circles in the last 5 years could be explained away as 'sometimes freak things really do just happen.' But I am certain that there is now way more of it. Prior to 2021, things like sudden fatal strokes/heart attacks, people dying in their sleep, young people with strokes and embolisms, sudden aggressive cancer, rare cancers, etc., as well as sudden deaths where no obvious cause is found, were nowhere near this common. Something is going on.
