People who wish to avoid liver disease and cancer get rid of all the artificial fragrance chemicals in their homes. And once you do that for a while, your sense of smell is restored and you become quite sensitive to artificial fragrance. This brings up the point of the old lady perfume bombs.
You know what I'm talking about, too. It's that older lady, dressed up in all kinds of jewelry, big hair, and absolutely showered in perfume. Just walking by her makes you gasp for oxygen. You run into these women (yes, they're always women for some reason) while shopping, in movie theaters and even sometimes at the gym.
This comic supposes that we might turn these women into chemical weapons by unleashing them upon enemy nations. Their mere presence will cause enemies to fall to their knees and beg for mercy. All they gotta do is show up and remember to bring their perfume.
