It would be a reasonable medical hypothesis, that before the Covid vaxxes, the phenomenon of peak fit athletes collapsing, sometimes dying on field from heart conditions, being exceedingly rare, would justify as a medical hypothesis, that the vaxxes were doing it. But the mainstream media if mentioning this, seldom mention vaccine status, and almost certainly such athletes would be fully vaxxed up, having to travel. There have been some brave souls who have called for an investigation into this issue. Maybe the system will get around to it in, what is effectively a “thousand years” that the US FDA would like to release its Covid vax documents!
