I have a no-mask relative. He got covid over a month ago, gave it to his wife who had to be hospitalized and both are still gasping for air and wishing he took better care. I wear two when I need to. Not a problem. Especially when I consider the possible alternative. 47 covid deaths here today. So no thanks I'll stick with science on this one.
ps I see your great Swedish 'herd immunity' promotion didn't do so well and had to be significantly 'tweeked' as the death rate rose to 'highest in Europe'. 14,000+ deaths as of April 28. Surprise, surprise.
