The leading cause of death in multiple Canadian provinces is now "unknown cause." There's been a roughly 1700% increase in the number of young, healthy athletes collapsing dead in the middle of sporting events. Embalmers are finding long, coiling blood clots in cadavers, the likes of which they've never seen before. There is a record number of birth defects, lost pregnancies and stillbirths. None of these factors can be explained by anything other than that there is something fundamentally different affecting human bodies over the past year and a bit.

There will always be those NPCs who are so attuned to the Current Thing zeitgeist that they will actually trust the experts over their own memories and believe that things have always been this way, but for those normies who possess even a small amount of awareness, it's important to keep hammering those things home.
