The concept that I want to use is innate immunity. Innate immunity is our first body response, which we are also already born with, to fight off different harmful substances. Some examples are fever, inflammation, etc. I would use this concept in terms of identifying if there is something that is wrong with my body. Since this is the first response to protect our body from harmful substances, manifestation of the symptoms of inflammation, fever, etc. is a signal that there is something wrong with our body. Having this information, I could help myself, and even the people around me, to seek help or take a rest to prevent the condition from worsening. Understanding this concept has the potential to save lives.
