If you are a world inhabitant, then you have likely been affected in some way by this new pandemic, the Corona Virus: COVID19. The current fad nationwide is to wear a surgical mask, because the way that this virus is transmitted, mostly, is by getting it on your hands and then touching your nose and mouth, and thereby transferring it to your respiratory tract where it can cause all sorts of havoc and even lead to your death.
While the use of a paper or light cloth mask is better than not using anything, consider the fact that muscle memory is a powerful thing. It is inherent to the Pavlovian theory of conditioned response, and is even relevant in cases where you are either unconscious or asleep.
A simple paper barrier is easily manipulated in the event that you have an itch or sensation in your sensitive E.N.T. tract. The fact of the matter is that you will only be truly safe from inadvertent infection if you are able to establish a significant barrier to your respiratory tract that cannot be easily traversed. On the same token you have to be able to respirate.
Though it’s not exactly designed for such a measure, consider then the advantages to using a military grade gas mask to prevent becoming infected by this troublesome virus. If you observe what the professionals use when they are trying not to be contaminated, you see that they often wear a head to toe PPE kit with, you guessed it, a cranial containment apparatus that separates the respiratory system from the environment.
You can achieve the same effect without breaking the bank or having to re-invest in volatile equipment. A military gas mask is easily sanitized and can be re-used indefinitely. There are millions in existence right now, worldwide.
