By "time and time again" do you mean "not once"?
It doesn't matter, though. Jerry has made it clear. When people, including his wife and doctors, tell him he needs to make changes because of his health issues, he doesn't want to hear it. "I ain't changin!!"
A defiant patient unwilling to work toward better health can be difficult. Hopefully he becomes more willing to listen.
You do realize you are using quotes from Jerry that are 2 years old right???
Some quotes from someone who knows him just a tad better than you do:
“He’s not in it for the money, he’s not in it for the fame,” Limegrover said. “He’s in it because he loves kids, he loves the process, he loves building something special wherever he goes.
“And if he doesn’t feel that his health is allowing him to do that, he’s gone. There’s no doubt about that.”

What I gather from that is, if Kill's doctors tell him his health is in serious jeopardy because of his job, then he'll walk away. That's the problem with how some of the media is reacting though, they think they're Kill's doctors and they know best. In reality, they have no damn clue.
