Pheromones

Pheromone: A chemical secreted by an animal that influences the behavior or development of others of the same species, often functioning to attract the opposite sex. Pheromones are natural chemical scents the body produces in order to communicate with others nearby. They are well documented in the animal kingdom as the force that controls all social behavior, including mating. Scientists are now finding that human behavior is also heavily influenced by these invisible airborne chemicals.
