Death by Breathing

Once upon a time, in a galaxy far far away, I was a little girl.  I know, its terribly shocking.  I might even keel over from heart failure at the revelation of such a fact.  Anyway, one day when I was about 5 or 6 maybe, I was rolling around on the floor (another frightening truth) and I came across the carbon monoxide detector.  Not knowing what it was, I asked my mom.  She explained that it was a thing that was used to keep us safe, and it would beep if there was too much carbon monoxide.  She said that carbon monoxide makes people sick, and so it was important to have one.  I don't know at what point in this story I realized that carbon monoxide is totally the stuff you exhale when you breathe, but that happened.  And I even asked my mom, "So if you breathe on this enough will it beep?" "...no...".  But did I believe her?  Of course not.  So I experimented.  I sat there and looked at the detector, and when I made sure she wasn't looking, I started exhaling repeatedly, hoping the numbers would change.  Of course, they did not.  My experiment had failed.  At such a young age I was extremely impressionable, and such a great loss caused a lot of trauma... just kidding.  I continued being a happy child.  Well, after I got over some of the symptoms of breathing heavily for no apparent reason.  Which, coincidentally are roughly the same ones as those caused by carbon monoxide poisoning!

WARNING: Do not try this experiment at home.  This experiment was conducted by a trained professional who did not heed the advice of her mother, and... well... look at what she has become.  Don't become what she did.  Just say no.  XD
