To a certain extent, there's always a certain amount of drop-off in dexterity and stamina as we age, or find less time to practice, etc., but the main thing, and it's something those TV stars miss, is to have the wisdom to adapt what you play to those new realities. They find themselves stuck HAVING to do what they did in their youth and prime, because that's what the people expect to hear.
We, fortunately, usually have less audience expectations

Plus, just like probably many of us here, I found myself spending the first twenty years learning how to play, and now I find the next twenty years learning how to NOT play

(at least, so much

). You can do the tastiest of things with half the technique you used to use, once you have the wisdom to recognize what IS tasty...
