Yes, it is very curious. I know a couple of people who haven't changed their lives at all: public transport across London every working day, even going to work during lockdown, working amongst crowds of people, and not so much as a cough.

In more "covid is weird" data, I have a friend who got long covid pretty badly, I think caught around the time of the first UK wave. Then he recently got it again and once he'd recovered from that, the lingering long covid effects seem to have gone! I'd scarcely believe it if I hadn't seen him.

Sounds like Rich Stokoe's experience. Well, the first bit. Not sure if he's had it a second time, but I do remember him talking about the second infection long-covid "cure". He's probably running around Newcastle licking people/things trying to get infected again.

So far both Rebecca and I have avoided it, but my sister in-law Sarah and her family have recently been hit with it and Rebecca and Sarah work together in the same school, so it's only time before it turns up here.
