10% does seem crazy high. But it's also possible that some long covid effects go noticed. Also totally anecdotally, but I heard multiple people say they just don't feel as fit now doing cardio, myself included. Is it we're just older or did we get slight lung damage? Or worse, heart damage. Our bodies are really surprisingly sturdy and able to keep up with damage for a long time.

I know 2 people with severe complications from long covid. And I don't know that many people. So how many around me are living with mild long covid complications and don't realize it?
