If I was less infirm than I am then I'm not sure that I would continue going to crowded events as I used to do. Am I living in fear - absolutely no way? Just adapting and being careful.
FWIW here's my position on masks ...
I was always sceptical about them because in the past they were never recommended for people with compromised immune systems and we were told they don't work for the general population. That instruction was reversed without explanation: either the original claim was a noble lie, very, very dangerous, or they had some new evidence they weren't sharing. In the end I think it was political theatre.
I have worked in Asia and when people there wore them it was because they were symptomatic or trying to keep smog out, nobody ever claimed they were a protection against an aerosol virus, at least to me.
Despite that I voluntarily wore one before they were mandated because it sent a signal that I understood we were in a situation that was unknown and that I took it, and still do, seriously. When it was mandated that signal got lost in the noise.
Since then we have many natural experiments with countries and states having different policies on masks, including Bavaria mandating FFP2 masks, and nobody has been able to tease any correlation out of the data to show they've had an effect. It would be very unusual to have effect without correlating data.
Probably the best trial has been Bangladesh and the aimed to show a 10% reduction in cases. However since the data has been released even that result is being questioned.
Now that its been confirmed that the virus spreads by aerosol the efficacy of masks is further questioned. I once went in to a gas chamber with an ill fitting gas mask, never again. I would not go in to a gas chamber with a surgical or cloth mask on (even wearing good goggles). If a mask can't stop CS there's no chance against an aerosol.
But that isn't my concern about masks - that would be risk compensation.
I worry about that on 2 fronts: people going in to places with a mask on that they wouldn't go in to without one and, more selfishly, people thinking their masks somehow protects them and me and getting too close to me.
I won't go in to any situation with a mask on if I wasn't prepared to go in without one. This happened at the weekend. My wife happily donned a cloth mask to go in to our village hall for the Christmas Fair, I refused to go. No windows open, everyone cheek by jowl and the Zoe app showing that we have 4x the cases in the area than the last peak.
When asked I wear one, I've just had an hour of physio wearing one, and I will now wear one in shops, just so the staff don't have to get stressed out asking me to wear one, but I'm under no illusion that its doing me any good and it could even be be more harmful.
