I never check a watch when I am inside a Rewe Markt, maybe 22 minutes and I hate it. Gives me a mild headache every time, can't see true my glasses very well, breathing is more difficult but what can I do this time? I take it off the second I am out of the Rewe Markt. You see, I need to buy food and I don't want to pay a fine or get attacked my idiots. Thank you Corona, for showing me what a sorry ass species we humans really are. And I don't believe it protects us better from anything. To wash your hands with soap and cold water is legit. To enjoy a lot of Vitamin C also but this mask thing is just false.
