I agree with this 100%. I lived in an apartment and imagine my shock  
when I realize that my ELECTRIC stove's exhaust fan was not on an  
external duct but simply blew the toxic smoke from burning food back  
into my apartment. This is, from personal data, so much a bigger  
effect than gas stoves on lung heath, that I think you need to write  
an article on this professor. I mean the very principle of a fume hood  
in chemistry lab, if your cooking generates cyanide gas, is that as  
long as it is properly vented to the outside of the lab, you the  
experimenter is perfectly safe. This is a huge insight, Dr. Wallace,  
and inevitably leads to the conclusion that proper exhaust of stoves  
is orders of magnitude more important than what fuel is used.
