I'm in the business of pheromones now. No, not for people, for bugs. Mostly moths. You see, spraying an area of orchard with pheromones will confuse the moths trying to mate, thus making them think there is a mate everywhere, when in fact there is one no where. In other words, no baby's, no troubles. I guess this is closer to biology, but I work with the pheromones, so there's the chemistry.
