In the years leading up to covid, I was a caregiver for my grandparents and watched them slowly lose their minds before they went. My grandfather was especially bad at the end. So my two biggest fears regarding covid are the death of Herd Immunity, which we’re watching occur, and this shit. 
shop around and you may find some on short dated masks on heavy discount. often these will still have 6 months before expiry and are probably still fine to use afterwards anyway.
