Let's try again: put your fingers on the side of your trachea,
just at the base of it where the throat enters the body. Press slightly and pull suddenly sideways.
There will be a choking sensation, pain, and coughing. Now, imagine that situation happening with a mask on your face and without expecting it.
So, don't lie to me. Anyone reading here can make that experiment and will confirm what I am saying. It is human biology.
Disclaimer: Do it at your own responsibility. It is unpleasant sensation and it can lead to choking and other unwanted reactions.
