Kingfrog.....I feel very sorry for you. You sound like a very unhappy person who has nothing better to do with his time than hang around trying to rip other people apart.

Have a little more class and DON'T do it in
a room where the subject of a potentially debilitating disease like Diabates has been brought up.

I responded to this the way I think the OP felt about it. If something like that hits you hard, you can say goodbye to your music career.

Some of us are still playing and there are other things to think about in addition to scales, arpeggio's, triads, and a few dotted quarter notes.
