This is an easy one for me. I live alone in a small one-story home with an appropriately placed fire alarm. I can exit to the outside from every room in the house, via windows or doors, without any long drop to the ground. We have a local volunteer fire department in our little community that can be at my house within minutes as the fire chief is my next door neighbor.
This does, however, remind me to ask my son 2 who recently moved his young family into a two storied home whether he has thought about fire escape for his children.
