Do you have a source I can look into about the dna stuff you wrote? That’s very interesting and I really hope you are right.
Regarding the other injuries, I don’t think it’s caused from stress, lockdowns, or sedentary lifestyles. Lebrons son is an athlete that collapsed long after the vaccines were distributed (maybe 1-2 years later). And that football player Hamlin collapsed I think the second year after the vaccines were given. But these athletes still train during the offseason. Soccer players have had similar issues too. If these were fat and older people I would be more willing to accept your argument. If those athletes collapsed, and others did not, that means there probably were signs of inflammation in the heart leading up to the event. That presumably means we can probably see it with an MRI.
