Even experts do not agree about wearing masks in public. So how should we? There is strong evidence and also common sense that a mask prevents the droplets from spreading in the exhaled air. The mask protects the one that wears it but what is more important it can protect tens of other people from the infected person. While wearing a mask has been very common in some cultures before Covid19 outbreak, for others this is still unusual and strange. Current pandemics might change that.
Commit to wearing a mask in public and protect others. If you ever wanted to be a hero by saving other people's lives this might be the easiest way to accomplish that.
