Did Elvis really die from a heart attack?

We may never know for sure, but the leading theory is cardiac arrhythmia (a heart attack) possibly brought on by either a drug overdose or a bad drug interaction; a postmortem autopsy showed traces of 14 drugs in his system, 10 in significant quantity.

Parallels might be drawn to the recent death of another pop superstar, Michael Jackson; when one has achieved a certain level of wealth and fame, it becomes easy to afford whatever medications one wants in whatever quantity one desires, and to find those people unscrupulous enough to provide them with no questions asked.
