I assume you have a table at your home. Here's what ya do:
Ya put on Bird, or Diz, or Miles, or Trane, or Ray, or McCoy, or Monty, or Quincy, or Bags, or Wes, or Art, or . . . .
Ya go to the table and you shoot and listen. If the balls go in, great. If the balls don't go in, you're listening to great music. Win, win, win. One hundred years from now it ain't gonna matter whether you made that ball.
Another thought: Age? It's just a number. You know that saying: "You're only as old as (the women) you feel." LOL!!!
Seriously, extract joy outta what you can with the years you have left. It doesn't matter if you're not as good as you were. You're still good. Embrace it, play around your limitations, and just f'ing have fun.
