I love this explanation of how the harmonica 
changed your life @Luke!
The harmonica has also changed my life and though my own transformation through music has been much more recent, I’m sure many can connect with your story, as I have.
This article explains Mick Jaggar’s own experience with the harp.
I thought about you @Luke when Jagger talks about how difficult it can be to teach someone how to play the harmonica. You excel at this fine art 
and for this all of us here are grateful 
My grandson recently first blew his first notes on the harmonica and it was amazing to see how he lit up when he realized he was able to make noise by simply blowing and drawing into my old C harp with a blown 4 draw. He doesn’t seem to mind the lacking notes and I’m thrilled to help him get started learning a “language” which I am just now learning and wish I had learned a long time ago.
Music seems to me to be very much like an entirely different language which enables to communicate with others around the world regardless of our spoken language.
Learning more about this language which has always been around me and I have always heard but not fully understood, has been incredible!
So nice to share similar experiences with all y’all
