I read so many posts on Michael Jackson's death. Many reported that he died of cardiac arrest. And i've also read a few that says he died of a heart attack. Well, the truth is, Michael Jackson died of cardiac arrest and not of a heart attack. They are not the same, ok. Go Google on the difference between the two and you'll understand why. It's important to know, ok. Dont simply speculate on Michael Jackson's cause of death. I miss Michael Jackson. He's a real Pop Legend.
