And then practice makes perfect is the old saying you know? You practice, you know?  You can't just stay in a...age hasn't really much to do with it. I mean that's, I've had that argument so much in Europe, you know. A lot of people think when you get old you can't play this or you can't play that. Age has nothing to do with it whatever. But education has a lot to do with it. You know? Education. Knowing what you're doing and the next thing important is to know what the other fellow is doing, because you can't copy if you don't know what the other fellow is doing also. So that's the way I keep up.  And you have to practice too you know see? Then another thing I think is important, don't never get to the point that you think you sound so great, you know? You know?  Always think there's more room for improvement. See because in music it's a science.  There's no such thing as finished. You can always get a better tone. You can always get better ideas. You can always get new harmonies. So many things you can always...as long as you live see? So that, I think that clears your question.
