Re: Wierd Al\'s parents past away.
These types of accidents are really a bummer.
Suprisingly, there are a couple climates that have higher than average deaths from CO. One is in a mild climate and the other is in a very cold places.
In the moderate climes people use space heaters more because their houses don't have the insulation/high output furnaces that the colder climates do, so they have more accidents. 20 years ago one of the leading causes of death in Japan was space heaters, for this reason.
Since the big energy crunch of the late seventies there have been more accidents of this type in the cold, northern areas because people have sealed their houses up much tighter in an effort to reduce their energy consumption. If you live in an 'energy effecient' house up north you must be much more careful to assure adequate ventilation with portable heaters than if you live in another clime.
