I love that man. I suspect he may well have some neurodivergency issues that are still regarded by most as 'weird' but will be as accepted as nothing in 10 years, much like many things that were illegal in the 60s, or certifiable, are regarded as all part of life's rich tapestry, today.
I have nothing but admiration for the man. Conquered his demons and came out the other side a better man, who is now dedicated to helping others cope with the issues he survived. And taught himself the piano. A captain and a leader in every sense of the word, good luck to him.
