One of the drs. that has been against the vax said that there are particles in the jab that under a microscope look like shards of glass. They perform the same way. As an elite athlete exerts themselves, the ‘glass’ particles move more rapidly thru their blood/lungs (or other organs) acting like a razor blade cutting thru tissue. If you laid out your lungs, with the tissues and veins, it would be half the size of a tennis court. He said the autopsy pics that he got a hold of showed the heart/lungs perforated and torn. These athletes are collapsing when training or during a game. The optimal time of their greatest exertion.
