I apologize if you don’t fully understand the biological reference being made, I wrote in a rush and didn’t clarify that it was in reference to human evolution and adaptation. Our DNA is the driving force behind the the physical changes through multiple generations of adaptation to the world around us, known as the Evolutionary Process.

One of the evolutionary our ancestors went through was creating the ability to involuntarily form mucus and to cough as a way to combat threatening viruses and such.

The fatal evolutionary flaw of these involuntary reactions is they can potentially react to non-harmful substances which are allergies, such as pollen, dust, peanut-butter. They themselves aren’t deadly, but, those with allergies, have a defective part in their body’s biological make-up which sees harmless foreign substances or micro-bodies that have entered our bodies as all out threats. The body reacts by attempting to push it out of our throat and lungs by coughing, trapping potentially deadly viruses in our mucus/wax build up, and by eventually blocking the holes in our head (nostrils, throat, ear canals) from any further threats, hence why we get stuffy noses.

In the worst case scenario, our body can unknowingly trick itself into swelling up our tissues around our neck to cause our airways to be constricted until they close up completely, as the body sees that as protecting us by blocking our main entrance into our body. The body doesn’t realize it’s doing something bad so we must force our body from reacting by a certain injection for severe allergic reactions.

Was there something else that was confusing in my statement?
