RE:It's getting worse, covid in BC. May I suggest that you appear to be getting overly paranoid about this "space" element. Somehow I envision you walking around with a big measuring stick making sure no one infringes in your "danger zone".
I do go for a walk everyday and there is the 'odd' person that will not pass me on the sidewalk but will go outside the parked cars on the road to avoid me. I have not seen anywhere that there is proof that those little covid particulates are hanging suspended in the air to attack you as you pass by. Not sure if they feel they are protecting me from them or themselves from me. To each his own. Try to enjoy your time out with others.
