If someone INTENTIONALLY set fire to my home without being able to get out of it on their own, I'd really have to wonder why on earth they picked my place for self-immolation.
As for belongings, I wonder how far down the list of my priorities I would actually be able to get in ten minutes. The one-minute version is easy(grab phone and medical records folder; walk downstairs; grab purse by door; walk out door), and if I had an hour and can assume use of my car(disaster evacuation or the like), I have a rough idea of the order in which I'd load. Ten minutes... might be worth practicing. I'm pretty sure that would let me get my laptop, my underwear, and the few framed photos of family and friends that I have, but I don't know how much more I could get.
