there are a alot of pros whos career ended pretty soon.some of those pros are jim quinn,mike mentzer,kal schalak,lou ferrigno,ian harrison....
Some didn't want to make it a career choice, just wanted to prove to themselves they could do it.
Some had health issues.
Some had financial issues.
Some had drug issues.
Ferrigno has seen the highs and lows of bodybuilding.
From the heights of playing the Hulk on TV, to the lows of depending on residual income from picture signings.
Ferrigno may have lost to Arnold when it came to life, but Ferrigno still looks in decent shape while Arnold looks like he never lifted a weight in his life.
