Yup, I do it to. In fact, I hate the sound of my heart beat. I can't sleep on my side with my heart facing down because I just hear it over and over again.
I remember this one time I was really sick (had a hard time breathing) and they hooked me up to this breathing machine with steroids. They had my heart on a beeping monitor. I kept hearing it over and over: "beep! beep! beep! beep!" and because I could hear it, it started going faster and faster until finally it just flatlined. The doctor took the thing off of my finger, and starting taking my pulse with his watch. He said: "You have to calm down!" I said: "Fine! just don't let me hear my heart beat again!"
