I am 41 years old and have been playing video games since home consoles were invented. Played PC games since 386 and handhelds since Colleco Football and Merlin.
I helped the editors of Dragon magazine develop the first mods for the first dice and paper RPGs. I even helped Chef think up a new name for the artist formerly known as KousKous. I recall we had meatloaf for diner that night.
I listened to punk rock when I was a kid in the 80s and still listen to indie music today. I don't think I'm that much of an exception for people my age.
No, you never really stop. Many people I used to play don't have as much time for it anymore but still give it a go. Some give it up when they realize they're not as competitive as they used to be.
At our age we don't have hours a day to devote to gaming, but we still like to jump in there.
But nothing beats the pleasure of learning the nuances of a new game.
