I have a lockbox that, while it can withstand one hour of fire/water, does have a nice handle and is always accessible. Got my passport, insurance papers, and a few mementos of past coworkers and friends. Pretty light, as well. It's not something like a cellphone (I would try that, too) or my laptop(s), or my cat (always first), but does represent a lot of me. I worked hard for some of the things in the lockbox, but other things are just a bit sentimental, which goes against my usually-utilitarian-only, form-follows-function personality. They've got to be really important to get past my sentimentalitymeter.
