Except for a study from China that was released the other day, which I dismiss because it’s China, the studies go back and forth. In almost everyone study they continue to say it’s not black and white. Just read one this morning. As I said before, you can find what you want to prove your point (not you, I mean anyone)in any of these studies. Not one yet has said, it is perfectly safe to do this or that. It usually says, if you keep this distance and etc.. you should be ok.
Most do say being spread out is ok
