And that pinpoints one of the problems I have with the
LIGHTS OUT book:  sometimes I think their basic premises are
a bit shaky.  They say we should be going to sleep at
sundown, and only the advent of fire is what has made us
change this.  I find this a bit difficult to swallow whole.
While some things may have been more challenging after dark
without a light, it is hard for me to agree that this made
these things totally "undoable."
