You're an idiot. People who don't die from wrist cutting usually DON'T even have the intent to throw their life away but to cause self mutilation, people who do tend to make more deep cuts. The girl in the commercial most likely severed a vein which when cut causes heavy blood loss, if the father didn't find her in time she would have passed away. Oh and if you haven't figured it out yet Heavy blood loss could cause death. If you somehow didn't know that.
