I don't [think I] produce acetone when dehydrated, though I do then get bad breath from other odorants; however, there's a correlation between running out of water and running out of food, which may make people associate acetone breath with dehydration. To my nose, the odor from antique :-) 35mm film is other than acetone. James F.
