Each time you catch the flu you also accumulate damage. Same with every disease. Just because you feel back to normal after getting over an illness it doesn't mean there isn't a permanent hit taken in terms of future repair & recovery capacity. I suppose the argument is that Covid-19 causes more long term damage in many people when compared to other similar illnesses? That's interesting, but part of me wonders if this is just a false flag due to how much research there is going into covid.
