Hope he pulls through.
Covid is no joke.
A co-worker of mine got it just before Christmas. Fit guy, very healthy generally, former athlete on a fairly high level - but has some slight asthma issues.
Nearly died - it was touch and go for a while. Just couldn't take in enough oxygen, relied on respirator treatment for days.
He recovered, thankfully - but he's still very weak. In his own words, he feels like an 80 year old man (he's not even half that age) - gets absolutely knackered from going to the store and back, etc.
Again - no joke (to those who still think this is some kind of normal flu variation).
