I wear a mask professionally at work. I sometimes do and sometimes don't wear one of these "decorative" masks shopping etc.,depending on the epidemic status locally. They are not perfect but they definitely do help. Just like washing hands and using sanitizer which remove most but not all germs on the skin. If you don't believe me just look at some people talking,coughing and sneezing in bright sunshine and you will note all the droplets coming out of their mouth ,which these masks help to control. How you guys in the states allowed the wearing of masks to be come a political (and by inference tribal and irrational) rather than discussed on a rational/lets do whatever we can to help our neighbours even if it isn't perfect level, I will never know. Now let's not get too derailed and get back to cars and fun stuff.
