yep
ur heart just stops pumping and if its longer then 2 minutes with no medical attention (MJ's case) your pretty much gone
but if you get the right help in time you can make it but there is a good chance you will have brain damage and you wont be normal (handicap)
found this out when Mike passed
while they was rushing him to the Hospital CNN had a doctor on there and he said that if he does make it out he wont be the same again like he wouldnt be able to walk again, or wouldnt be able to sing again things of that nature
