Whoever guess what I am gets gifted anything under 10k NX. I am the thing that you neglect, though I play a big role in your life. I get bigger as you grow helping you, sometimes messing up once in a while, but you throw me away as if I was a repugnant disease that is trying to bring you down. But little did you know that I am the thing that keeps a plethora of organisms from invading you and forever destroying one of your senses. What am I? 3 guesses per person. I will post when someone gets it right.
