Oh, PLEASE! That fucker had a history of drug/alcohol abuse. And just because he was "clean" in recent years doesn't mean those addictions hadn't already taken a toll on his body. What a quaint notion it is that once you join AA your Liver magically heals itself overnight.

Lifelong chain-smokers think the same thing once they quit and are always shocked when they still get Heart disease or Lung cancer... Saget himself once smoked SIX PACKS a day and died of a Heart attack. END OF STORY.
