Even old jokes can have a scientific basis in fact.
You know the one about the tourist who stops a native New Yorker on the street and asks, “Excuse me sir, but how do you get to Carnegie Hall?”
"Practice, practice, practice."
That New Yorker is absolutely correct. Scientists have found that the brains of professional musicians are physiologically different from the brains of other people, and they got that way mostly because of practice, practice, practice.
