Imagine, if you will, a burning house. Those things that will get saved from the fire will be saved in order from the highest value density to the lowest.
Those things with infinite value density would be family members, pets, objects with sentimental value, and private keys.
Then, of course, your high quality cowboy hats, shower filter, and a copy of The Bitcoin Standard will likely be next.
But please make sure your family members and pets are at the front of that line!
