There have been a lot of full moons over the past 50 years, and unlike we humans who have seen a great many of them that great crater-smeared round thing has not aged one little bit.
Because 50 years, in its lifetime of about 4.5 billion years, is a mere blink of the eye.
Which reminds me, when I was a little kid I once saw an old film where the moon had a face and at one stage of proceedings it blinked... because a rocket had smacked into it.
Or was it a cream pie?
Whatever, the moon blinked.
