Hello, my name is Sade, and i was reading online when i came across this article. It was about perfluorocarbon. I understand this is apparently a liquid you can breathe in? I know that it is improbable but is there any way to purchase it? I would love to know more about it, whether it is safe, or the damage it causes. The internet is not always the most reliable source and although after googling it once learning of its nature, I would love to hear a doctors opinion on it and even possibly write a paper on it, for I am a high school student of Port Coquitlam. Thank you
