Never stopped. Haven't had a respiratory issue in five years, apart from when my sister brought COVID into the house and infected us. Hoping to keep it that way for as long as possible. Need to book my next jab.
People are gross and don't want to think about how serious COVID is. Easier to just pretend it's not an issue any more. The stakes are too high for that for me. Cumulative damage and a jackpot prize of long COVID? Hard pass.
