I think you just proved how incompetent government isAdvice changes as the scientist get better information. They used to think asbestos was safe. They used to think smoking was safe. Miners used to deep breath fine powdered aluminum dust deep in their lungs before going underground to protect them. For things that might matter, I still follow the current medical advice from real Doctors. I don’t care if it was different before when Grandma was a baby. And I am not so stupid to think I know better than the doctors about how to slow the spread of COVID.
