So how do you know you had COVID-1984 twice, Carnac?
Symptoms. Some pretty unusual ones, which later on (part way through recovering the first time) were being announced as “covid symptoms”. Loss of smell, then loss of taste. Very bad pains in the bones in my legs. Also bruises on my toes appeared out of nowhere. Some symptoms which are consistent with flu and colds as well - but the weird ones were not consistent with either of those.
Not normal for a flu, but apparently are for covid.
