Peanut allergies have plummeted in children

Business idea: Allergen Aerator

Generate a miasma of benign pestilence in your child's crib, mimicking the protective inoculations provided by early exposure to peanuts and other potential allergens, "farm" air, and the like. It could be packaged with Flonase for sneezing parents and an 'essential oils' scent dispenser to cover the barnyard smell.

Use AI to tailor the precise blend of aerosolized rodent feces and tree nut dust to optimize your child's immune system, and et voila: funding!

Bizarre that this is the top comment as this would drastically increase the frequency of peanut allergies and, more than likely, end in multiple deaths. Research strongly suggests that the key is that the child eats peanuts before being exposed via other vectors (skin/lung) to avoid allergic reactions. Arisolizing the relevant proteins around infants is essentially fast tracking allergic reactions.
