According to my doctor father, "long covid" is basically nonexistent in under 18s and over 65s. He was amused by the coincidence that the only people who seem to be experiencing extended symptoms and effects of the disease are those who are "likely to want a decent reason to call in sick to work"
Not sure how much i believe that, but it does seem weird that kids (who've been off school anyway) and retired people don't seem to be getting long covid. Is there a medical reason that it's only affecting people 20ish-60ish?
