You don't quit playing music. Sure, skill can deteriorate, and often does... definitely has for me... but not play? You'll sooner see an honest politician. Not going to happen.
True that I've pretty much retired from playing in a band, regularly that is. But when I made that call I gave NO consideration to "not playing". That thought never crossed my mind.
That would be like saying to myself, "Well, getting old, watched a lot of Ram's football in my life... time to stop". Not playing music would be THAT whacko. - JamesJM
