Very true! For fun and education, perhaps someone local to me in San Jose would like to test the aging of a HP precision oscillator standard that has been powered almost continuously for a half century! It is a 107BR 5MHz standard which contains a wonderful crystal that HP used to make themselves. The only time it has been unplugged was while transporting it from Eimac a couple of decades ago. I have had it on a ups power system ever since. I have not tweaked the tuning in years nor checked its frequency recently as I am using a disciplined Austron standard with a loran-c receiver for my lab. The meter on the HP107 panel says it is still putting out the right amount of RF power. No repairs in 50 years; that is reliability.
