Eh. People's priorities change. His certainly have many times over! And crafty (well not really) how they chose the 'after' pic of him where he was still recovering from surgery a few years ago to put next to the Mr Olympia shot that was probably taken 25-30 years prior while in contest condition.
Though he no longer lives for his body the way he used to, I bet he's looking a tad fitter by now.
