Cleaning the air in enclosed places like grocery stores, hospitals, airplanes, cruise ships, etc. makes more sense but, common sense is short supply these days. There is already UV light technology created by a military veteran and used by the military in their bases? Why not apply the same technology in airplanes, hospitals, grocery stores for instance. Way cheaper in cost and we can end the useless debate about masks. More lives can be saved probably, even without a vaccine.
I would bet there are a lot of liberals who do not wear masks. You know, the radical protester types? Those who do not want to conform to society?
Ya know.... this whole mask thing.... and ya'll know I am highly in the strong proponent camp... but god almighty.... do I really need to see my landscaper riding that zero turn on the back 40 wearing a f'ing mask? I mean.... ....whatever. One can pen an IQ test here. There is a time and a place folks. wtf
