Arnold has been holding a lot of anger inside. He is just now starting to really let it out... that is, in regards to Professional Bodybuilding.
He doesn't like the distended guts. As a matter of fact, I think it pisses him off more than the competitors know.
Arnold also thinks everyone looks basically the same. Back in "the day" the silhouette of a Pro bodybuilder was unmistakeable.
Arnold thinks the general work-ethic has taken a dump... which it has for the most part.
Arnold also see's these young guys dying far too soon when most of his competitive buddies are still alive.
He knows that Pumping Iron and a few other calculated moves that he made really brought bodybuilding and fitness to the General Population, the "masses" ~ and he feels a little bit of guilt for not controlling the "sport' more than he has. He started it (pretty much) but has let it get off-track.
Did I talk to Arnold? No. Can I read his mind? No, but I know someone who can ~
