Much to my chagrin, I humbly stand corrected on my prior statement concerning
the relative weights of air and carbon monoxide (CO)!  CO is lighter than
air, ie rises.  (Pets everywhere can breathe a collective sigh of relief) ...
CO is a by-product of incomplete combustion, however, carbon dioxide (CO2) is
also a by-product ... and CO2 is heavier than air (Pets everywhere pay
attention now).  And unless you're a plant or alien, breathing too much CO2
is definitely not a healthy thing to do.
