You cannot help people unless they are willing to a least try to help themselves first off. When I go shopping I would say that there is maybe 5% maximum people wearing a mask in a place where it would be more likely to catch covid.
I have read about people catching Covid 3 to 4 times but they only have a look backwards when something goes wrong, to late then. Long Covid is a huge problem for those of us in the 60+ age group, imagine having some of the symptoms for months and years.
We know what works when dealing with it, like washing hands regular and wearing a mask when out and about is no big problem, except of course for those imbeciles that think they are having their rights impeded on.
In civilised societies like Singapore, Japan and South Korea (all of which I've lived in), nobody whines about having to wear a mask. In fact in South Korea it's a common courtesy.
