There is one theory missing from conversation that i think is possible and very sinister. The virus was put out on purpose. The reason might be that they just wanted to know what would happen. The more sinister theory of why would be that they attacted against west by knowing aging population and what it will cause to our economy. Kind of silent way of doing economical damage and conquering space/countries. By they i mean China.,(reply>), You are right over the target my friend. Great thinking.
