I still have my masks from way back. Still in their plastic. Perfect condition. Being prepared is never a mistake.
Ive got my cases of packages of masks... LOL. Many cases of everything but the rubber boots. Just a few pairs of those as they are easy to decon/sterilize. I am ready for a pandemic. I could work in a BSL-3 lab. No positive airflow suits so BSL-4 would be a no no but I likely would survive almost any BSL-4 pathogen pandemic. Would be able to cross most fallout plumes as well.
