you can't run at 100% forever.. eventually you get burned out, mentally and physically.
if I was jay, so long as I was still making money as a bber, i'd rock it till the wheels fell off. he may never win an Olympia again, especially with whatever's going on with the nerves in his back, but he's still marketable.
personally, I never though Jay had the genetics to be a great Mr O. sure, he was always big, even as a 20-something new pro, but IMO he never had that "quality" that you'd expect from a MrO. (aside from his wheels).
