Military-grade camera shows risks of airborne coronavirus spreadhttps://www.chron.com/news/article/Military-grade-camera-shows-risks-of-airborne-15794050.phpI raised an eyebrow when i saw the headline.
I mean, all you need to do is look at the huge vapour clouds some exhale when using a vape to see how far the virus can spread in the air... you don't need a military grade camera, it's visible on the street everywhere you look if you pay attention.
Not a fibre in my body will ever be convinced that wearing a mask does not help reduce the spread, it is so blindingly obvious that only a fool would argue otherwise.
