Amen to that! So many people have had similar childhood experiences or even lifelong but never contracted MAC so for us I think those kinds of experiences become a catalyst for susceptible people based on genetics and body type. I had a doctor look at me once and say I was “textbook “ for MAC based on Lady Windermere - referencing a book character. As a kid I was an outdoorsy type and my brother was a bookworm. He was recently diagnosed with lung cancer but was an avid gardner as an adult. He probably pulled weeds, but he also grew and smoked his own weed! All that gives us food for thought - living in a bubble would be no fun at all! Irene5
