I don't post here much, but I read everyday. I have over 35+ year in the dental field . I have worn masks the entire time without any side effects to my health. I have told Jeppy several times that her phobia to facts is ridiculous. And makes her look silly.
So to that end : Mark Twain was credited with saying " Never argue with stupid people . They will drag you down to their level and beat you with experience "
Or as Forrest Gump said " Stupid is as stupid does"
