Well, they didn't exactly save my life, but they helped me through surgery.
I had a small sliver in my foot that, if it wasnt removed, would get infected and I could have gotten gangreene. At the surgeons, I asked if I could listen to MCR on my mp3 player, and hold my Bob action figure. They let me, and through the whole surgery I was singing along to the lyrics, and my voice got louder if the pain got worse. It's not much, but it's true.
