As I age, I have found that learning new music is especially renewing to my cognitive ability. I am fortunate that I can also sing, so memorizing the words and performing both the piano and song together make even more demands on my brain. It’s amazing how it clears the fog. I find it very encouraging that I can keep learning even at an advanced age.
