I live in an environment where masks are still worn and where my temperature is taken multiple tomes daily, whether it be shopping or banking etc..
I avoided Covid successfully until I returned to the UK some 6 weeks ago for a brief visit.
I flew on an airline that still requires masks at all times yet as soon as I deplaned at LHR not a mask was to be seen.
Jam packed trains, London Underground and internal BA flights over the next week and voila, Covid positive.
i doubt you will make any difference as no one seems to worry about a virus that as others have rightly stated is now no longer viewed by the vast majority as nothing worse than a cold.
