NO WONDER SLEEPY JOE TAKES SUCH CARE TO AVOID THE VIRUS:   COVID-19 causes ‘chronic’ cognitive deficits equivalent to brain aging 10 years.

On the serious side, take this from someone who almost died of pneumonia at 33, and who has a tendency to catch every possible (and probably some impossible) respiratory virus: if you get a severe case, any respiratory virus will do this.  The same as damage to liver and heart. ALL RESPIRATORY VIRUSES HAVE THE POTENTIAL TO DO THIS.  Claiming it only for COVID-19 is an attempt at stampeding you.  (Took me years to recover from that pneumonia, and for the record, it probably shortened my life. I know it weakened several of my systems permanently, and set my auto-immune on an ever worsening path.)
