Joe Rogan about face masks

"I listened to this doctor describing masks and he said there is a certain amount of viral load that the mask will filter out but essentially he goes I wear a mask so the people don't think I'm an asshole. He said when you use a mask, it's essentially like a chain link fence trying to stop a handful of sand. He said some of it will get stopped, he goes but why do you wear a mask. He goes you wear a mask so people don't think you're an asshole and people realize you care. Unless you're wearing a tight fitting N95 mask, it's really sealed off and then how are you getting air in?"
