I firmly believe that in America and most other countries the elderly have become a very heavy burner on their finances to the point they have banded together on this and with China and America the ringleaders,{with our communist leaders in power) developed a disease and then a cure with a vaccine laced with contents to work heavily on the elderly, the few younger people killed would be just an acceptable outcome to rid the world of this heavy financial burden. They saw most of the herd complied and how easy it was to control the herd so get ready for bigger things to follow till they solve the old age problem.

But I have no proof and this is just my opinion.
