 There's no direct proof that his illness was actually caused by the fires, which is sometimes a problem with inflammatory diseases. You can't prove causation, but he feels certain that it is linked. Because I don't know that it was a one-time event. I do know that it flared up in that high time of stress and toxicity of the fires. That level of trauma and burnout and on top of the toxicity from the smoke, I feel like there's a direct linkage there.
