Let's say that I power up an Arduino that will not power off in a decade and store a string on a variable, will the variable value/string still be there? Or, over time, will it decay and become corrupt?
What other things should I be looking for if I'd like to run an Arduino non stop? Like long vars, long numbers and increments? Possible hung avoidance for rookies?
Jesus handed me a 5v battery and about a million amps that last 10 years.
Thanks.
millis() timers will have to be written to deal with rolling over.
As for the part about decay I have no idea. It is a interesting question.
Decay, it's right in the datasheet:
Data retention: 20 years at 85 degree C, 100 years at 25 degree C(1)
I don't see anywhere what Note (1) is.

They already handle rollover.

Don't use the String class. Be careful with, or don't use, dynamic memory allocation.
