It does happen to some, l’m one. I’m 67 overweight but no other health issues. I’m not on any meds. I came down with the virus the third week in January and am still recovering. The things that still effect me, although much less now, is forgetfulness, lack of concentration, endurance, and shortness of breath. I figure it will take another 4-6 weeks to get back to where I was, but that is just a guess.
My daughter-in-law’s brother-in-law also had some, what he describes as “brain fog”, lasting for several months so far. He is mid 40’s, I think. Fairly overweight, but otherwise in decent health. I think he had Covid in December.
Hoping you continue to recover!
