Ronnie destroyed himself with Statins and Opiates and traing through injuries he was too spaced out to feel.
Yet there are other bodybuilders who are super strong who have not done so, as I mentioned earlier. Plus, we didn't know Ronnie "destroyed himself" until years after he retired. Very few (if any) complained about his training style, when he was winning Olympias, left and right.
BTW, who the heck said Mentzer was the "uncrowned Mr. Olympia"? He got beat twice by Frank Zane. And he placed 5th behind a sub-par (by his standards) Arnold, an even smaller Chris Dickerson, and two other fellows.
There's a time to lift "heavy-@$$ weight" and there's a time to back off and let bones, tendons, and ligaments heal.
