Bourdain: The Definitive Oral Biography by Laurie Woolever:
MORGAN FALLON: It was fucking insufferable. I would try to telegraph to him, over the course of these hundreds of conversations about jiu-jitsu, like, “Brother, I have no fucking idea what you’re talking about; I have no interest in what you’re talking about; I will never know anything about what you’re talking about; this is purely an endeavor of you telling me the same stories that you’ve told to everyone else.”
He was a lifelong addict, man. If it wasn’t heroin, it was work. If it wasn’t work, it was jiu-jitsu, it was relationships, or any number of other things. The way that Tony’s power went out to the world was largely through his various addictions, and I think he very clearly understood that he was never gonna be someone who was free from those addictions.
The jiu-jitsu was good, because largely it was a positive addiction, and so, as much as it was fucking insufferable to sit there and listen to him talk about something that I knew nothing about, over and over and over again, I wasn’t worried about him. I wasn’t worried that he was gonna collapse, or have a heart attack, or die of emphysema.
