Do you know anyone with a severe peanut allergy? Its actually far more serious than Covid. You could eat some peanuts, go into a room hours later and they could have an anaphylactic reaction, so actually its a very good analogy.
I wear a mask when required, but being I live where I do, I am able to stay the mandated 6ft away 90% of the time, which of course does not even matter since I have had the virus.
