Do dormant bitcoin wallets go stale? I have a bitcoin wallet. There is not much money in it, and I do not want to run bitcoin-qt all the time.

I have a question. If I save it securely, so I can recover it at any time, but do not run it actively with bitcoin-qt, does the wallet go stale?

In other words, if, hypothetically, I have my wallet.dat safely in a file but without any software actively running it, will I be able to reinstall bitcoin-qt after an arbitrarily long period of time, read wallet.dat, and use the money stored in it?

Or will it somehow be completely out of sync?

Thanks
There is no expiration date for when an output can be spent.
