Often heard in NZ that a mask is to protect you from me. Masks are notoriously uncomfortable and so any protection offered to the individual wearing them is a function of how often they do not touch, readjust, fidget with them or wear them on their chin. People struggle to not touch them and to do all of this readjustment frequently. Stop and watch someone. Most will fiddle and readjust the mask several times. Even a medical professional I was watching the other day adjusted, moved, and shifted his mask several times in a 15minute meeting. However, if everyone wears them, those who are infected filter out their ejected virus into the inside of the mask, thus protecting you from them. An online experiment from the science guy in the US, Bill Nye I think his name is, shows clearly what is what. If you can blow a candle out while wearing a 'mask', the so called 'mask' is ineffectual in any capacity to filter virus from being ejected thus potentially infecting a room full.
A scarf or 'mask' that you can blow a candle out with does four fifths of five eighths of very little in terms of protecting others from the wearer and vice versa.
Also a big bug bear of mine is people who wear the N95 mask with the air vent to make it easier to breath out. In terms of protecting others from the virus in case the wearer is contagious, is no value.
