I watched the first half and found it moving. KG is showing those of us who don't know anybody with covid how bad it can be.
Many months ago, having read an article in the Guardian about a young man, I posted a suggestion asking people to warn their youngsters about the dangers of long covid. This young man, in his mid twenties had previously led an active life, running about 5 kms 3 days a week. From what I remember he was a hospital doctor. After being ill he couldn't even walk upstairs without difficulty.
There was an interview with a nurse suffering from long covid who had formerly been in charge of a 40 bed acute ward. Now she cannot boil an egg because she forgets until she smells burning. She's not an old person, nor is Derek Draper.
I find it annoying that several GNers seem to think that few young people get covid but, they do. Because they're young and presumably in reasonable health, I assume that their bodies are fighting the virus more strongly than an older person, thus causing a bigger strain on those bodies which is why they are sometimes taking a very long time to recover.
