I am sorry, M. Ted. I used 'optimum' in the sense of 'the best of all possible worlds'. And since you stated your situation matter-of-factly I chose to accept it that way. I didn't mean to offend. Let me go on record as believing that EVERYONE should make music in any way that he or she wishes and can manage. I, personally, plan to go out with a tune in my head, and if I can manage it, a song in my heart. So here's to ya! Ebbie
