You are still young enough to get very good at the piano (keyboard). 69 is not that old. I am 72 and I have never practiced as much in my life as I do now. I am playing Chopin, Rachmaninoff, Debussy, Liszt etc. I found at my age music is an excellent way to keep the mind fresh and well tuned. It also helped me with a little arthritis. Age is only a number. I wish you the best in whatever music you may choose to play.
