Well said.
We have really clear evidence on what works.
I wore N95 masks in crowded public places/places with poorer air flow, and managed not to get it - finally caught it from a family member. I have no underlying health conditions, had all 3 jabs offered. I'd had hard times with flu once before, which is why I was careful.
I had long covid which made me properly exhausted and meant I had to cut down work for almost 6 months. Millions of people have similar.
I have never stopped wearing N95s since. It's not fear, it's not anxiety - it's genuinely wanting to be well and keep working that means I do the most sensible thing, because governments haven't done what UnmentionedElephantDildo has recommended here yet.
OP, you said you've had long covid, and I completely understand your concerns. I'd recommend wearing a mask in public places, as N95s or better are effective if you shape the nose band well. I don't know that there'll be another different pandemic soon, but this one is still quietly rumbling on because people just aren't wearing masks when ill, or opening windows enough/investing in ventilation enough. So all you can do is protect yourself. Then, even if you do get it, you'll get a lower amount because some will be filtered out.
