[Unfortunately, there is nothing I can use effectively in my vast arsenal bolstered by a grade-school education to counter what you've alleged. COVID-19, and its 18 milder predecessors poses no risk to the population.

Any suggestion the virus lurks within hermetically-sealed slabs is unadulterated nonsense. (None of the foregoing should be construed as my having less than the utmost respect and admiration for our much esteemed, learned members.)]
