"breath in molecules of air that has been contaminated with animal (and/or human) fats"
Bacteria a separated into flora and fauna. Many of them floating in the air.
Then there are all the microscopic creepy crawlies that live all over the outside of the human body, not to mention the herds of wild beasts roaming up and down your eyelashes. A true vegan should never wash!
Don't forget, sweat doesn't smell (much). The bad smell is the by-product of the bacteria using said sweat as sustenance!
