So the mask debate goes on. Conflicting opinions from professionals on both side of the fence divide us all. So what do we believe?

Here is a non scientific, everyday experience to gauge whether a mask is affective or not: You're going about your daily business all masked up, assuming you are protected against a virus. Here are a few examples to consider. Can you; Smell exhaust fumes? Smell when your baby has filled it's nappy? Smell dog poo? Smell someone's perfume or aftershave? Smell lovely fresh bread? Smell flowers? Smell when someone hasn't flushed the toilet? The reason you can smell these things is because tiny particles of the matter are in the air and are being breathed in by you. And you think a mask is protecting you - from what? This is a search result when I typed in how do we smell: In order that we can smell odors, odor molecules have to reach the inside of our nose, the nasal cavity. This usually happens when we breathe in. During every breath, the air surrounding us is soaked into our lungs. Within this air we find many different odor molecules. If we are standing in a bakery, many different odor molecules from bread will be all over the room. Every time we breathe in, these bread odor molecules will also be inhaled with the room air. And every time we breathe in, we will smell the nice odor of fresh bread.
