I thought it was common sense that covering your mouth with a mask would reduce oxygen levels and raise carbon dioxide levels in the same way that putting ear plugs in your ears would reduce your hearing or that wearing a blindfold would reduce your vision but commonsense has gone out the window these days. This firefighter does a great demonstration showing once and for all the dangers of wearing masks!!! Don’t comply and don’t give in to wearing a mask…inform everybody you can about this!!! Forcing children to wear masks IS child abuse so stand up for what is right!!!
