I don't wear a mask, except when flying. The last thing I want is to get sick from COVID-19, flu, RSV, or some airborne miscreant, and ruin all or part of my vacation, or getting back to work on the return flight.
The pandemic made me realize I can't trust people, can't take their word, not even my family. Trust but verify. If cannot verify, protect yourself in a reasonable manner.
I don't get into crowd situations anymore. No more very close conversations, keep a couple of feet distance. So no need to wear a mask with behavior changes.
Plus I love the free 5G for life. Simply amazing. Wearing a tinfoil hat keeps the signals internal to prevent snooping and reading my FIRE-ing thoughts.
