Who is Going to Believe They Saved or Prolonged My Life

It's hard to believe that in this life, as a human, we can be attacked by a little devil that can sneak inside us, attack us, and command his warriors to destroy our body. Who is going to believe they saved or prolonged my life? I wanted to thank everyone responsible for removing the little devil from my body and tell them, "Thank you for saving my life". I was surprised when I heard, "We haven't saved your life. We prolonged your life".
