Maybe 1 in a billion,but if you do pierce your ears, go to a professional, they will tell you how to take care of your ears and give you all the cleaners you need to use.
Maybe not really sure probably not though but you can get an infection if you get one of those then go to your doctor
Yes. My best friend can die if she pierces her ear with anything other than pure gold. But that is only because she has a hole in her heart
Well, I don't think you could die, but I'd rather get it done by a professional. But if you did it by yourself you could poke something in your ear and it would get infected.
