Easy to explain. We are like the overprotected chickens in the chicken farms. Protected and xaxed for several different things so have a weak immune system. In many 3rd world countries they survive by their body immune system so it is stronger to repel foreign or new viruses.
Yep. My take is that we’re now witnessing the beginning of a wave of “die offs” — the herd is being culled. (Those who are addicted to the “boosters” are willingly self-culling.)
