Hi my name is Penny and a very close friend of the family who is like a son to me is now fighting for his life from huffing compressed air! He has been serving in Iraq for over 3 years now and one of the guys dared him ...yes dared him to huff and I guess figuring they are big strong guys so he did it! He went into cardiac arrest and was clinically dead for 15 minutes before they got him revived and has been in a vegetative state ever since. He was on life support but is now breathing on his own but we dont know if he will ever wake up and if he does, there is severe damage to the frontal lobe of his brain which is what makes you who are, it controls memory, personality, consciousness or unconsciousness among other things. They say the longer he stays in this vegetative state the higher the chance he will never come out of it! PLEASE if you suspect a loved one of doing this CONFRONT them STOP them before its too late!
