It was the illness that did him in. It's winter and as a result of his illness he couldn't tolerate cold temps. Even living in Arizona he was still too cold. What he said was, the cold makes him shiver and that shivering would stop him from being able to breathe. Trying to live in the RV wasn't going to work as it was too cold. The divorce was unpleasant, the fire too, but those things didn't work to make him pass on. It was only the lung illness that did it. He last stated he had only 27% lung function after medical testing. His immune system was destroying his lungs, kind of like it destroys nerves in people that have multiple sclerosis. The body eats itself, so to speak. Cancer works in a similar way. All of the drug and alcohol use didn't help any. He couldn't do drugs in moderation, which is why he grew in the first place. He always had to have it around. I'm wondering how he was found and who discovered him.
