I think what you’re not picking up on is the whole Ms. Moos vibe on CNN. She is basically satire. She always jumps on the most outrageous stories and narrates them in that annoying pseudo journalistic voice and has done for decades. The stories may be actually true but you should never assume that they are. They are a knock knock joke for people who watch 24h news channels.
I don’t know anything about this case more than having watched the CNN video. Mr. Fir-lung and his doctor needn’t be actors. He could’ve really had it in his lung but played up the “haha, maybe I breathed in a seed” line because it got him attention on TV and paid interviews. And he doesn’t mention how he was in a landslide being chased by a bear 5 years ago and that’s when he accidentally inhaled the debris. The doctor may just have mentioned in a subordinate clause that it looked as if the sprig was growing in the lung but never actually claimed it did. Or he also believes in homeopathy. Or he also got paid for the interview. There are a thousand explanations why we get presented the story like that. But the biggest red flag remains that Jeanne Moos was reporting on it.
Your intelligence isn’t improved by calmness. Calmness may simply be the state when it is the most unimpeded.
