You can tell she was definitely 15 in the video though a bit more developed physicaly than the average would be. I wonder what posessed Brooks and Dun to use her as the center point of the video. The last time I heard of somone having a blood alcohol level that high was back in Michigan when a drunk driver wiped out a mother and her two boys when he plowed right through the car they were in. The driver had been arested many times prior to this incident in 05 but still had his license and in this incident had been drinking up near central Michigan and drove all the way back into the West suburbs of Detroit where he killed the family. I think at the time his blood alcohol level was 6 - 8 times the normal level and they estimated it may have been even higher.
People like this to have been drinking so much and for so long and their bodies are so used to it that they can have blood alcohol levels that would kill a normal person but you have to wonder what made this woman become such a self destructive raging drunk, atleast she's off the road.
