I am an avid outdoorswoman so yes, the level of NTM surrounding me does matter. I saw a recent study in Hawaii where the rock type there bonded with Mykobacteria. It was the very stuff beneath my feet everyday and rose into my breathing range via the cycle of enviro transpiration. I’m currently 64, waiting to go onto Medicare and have the ability to live almost anywhere, taking into account good medical and my family of course.
