Hand shakes are back too.
Or, well, they were before the Omicron variant.
Because seen that the vaccines either aren't working or are working for a very short duration of time (half the people in ER due to Covid are fully vaccinated), it looks like it's another round of lockdowns / scare tactics. The only clear thing is they're non-sterilizing vaccines: what's not even clear is if they're vaccines at all (I got my shots btw, but apparently I'm in the threadmill now for shots every 9 months...).
I don't know if people hugging / kissing / shaking hands can survive several years of pandemic fearmongering.
