BTW I find this principle to hold in many domains. Mental abilities, language learning, game, social skills, etc. Once you've built it, even if you take months/years away from it, it's still there, dormant - waiting to be reactivated in a fraction of the time it took to build it. You can use that to your advantage in many arenas.
If you can mitigate age-related decline (physical and mental), which is getting easier and easier to do, you can keep adding capacities and skills to your repertoire, and age like a fine wine, haha.
