The media also says that Pit Bulls are vicious monsters.

I don't have any solid proof but I have more than enough personal experience. I have 16 piercings.. three tongue and two lip piercings. I've had them for years and have had no heart problems. I'm friends with piercers and other modified people who have had their piercings longer than I have, and none of them have ever had heart problems due to oral piercings.
