Dude, you really are retarded.
"Oh wow! you had brain fog and you deny permanent brain damage????!!!!"
Of course Covid induces brain fog. This is a well-known effect of the disease. The question is whether the effect is permanent, which it is not. I was concerned about this very thing, so I took the test. As stated, my IQ is almost as high as it was 40 years ago, the small loss is perfectly normal in an old man like me.
But that's not real, because you found a science journalist hack that claimed it wasn't real, and WE'RE ALL GONNA DIEEEEE!!!!!11
