"You can't teach an old dog new tricks"; I bet if an old dog really wanted to learn new tricks, he could, but most old dogs like me, just find new tricks unnecessary; especially when compared to all the old tricks.
That was my introduction to the music I've been enjoying today; the music of "Sonny Stitt"; when Sonny Stitt met Charley Parker, Parker is alleged to have remarked, "Well, I'll be damned, you sound just like me", to which Stitt responded, "Well, I can't help the way I sound. It's the only way I know how to play."
