They don't seem to cause any serious health issues of note. The death/infection rate drops fastest where EVERYONE wears a mask. So they do help the one wearing the mask as well as those not wearing one. The clear shields are also helpful I saw on TV. No matter what you wear there is still a chance to get his horrible disease. And I just learned a person who had it already can get it again. Another thing are people with no symptoms at all who can pass it on. And they're also learning it can and does cause permanent damage to the other organs of the body. They're learning more and more about this virus every day. None of it good.
I think life as we've known it for so many years is over - at least for a long long time. And even longer if people refuse to co-operate by staying at home, not gathering in groups and wearing masks. Think of the economy....
We don't see anyone either. The snow-birds are gone and the rest must be shut up inside, shades drawn and shutters latched. We really feel the loss of the club house too. That adds to our feelings of isolation.
