That is quite a list Roger. If you need help with your cardiology homework I have a longtime personal friend who is a leading cardiac research scientist and professor of medicine at the University of West Virginia. My friend was at one time an alcoholic and drug addict who grew-up in a broken home. But my friend managed to get ahold of and deal with his demons and now he is very successful.
And you can get there too,
