Glad you are finding some applications for information design theory so quickly. Once you begin to study this field, you'll see that all living creatures depend on information to survive. Deer need to know where to find food and water, plants gather information about the direction and duration of the sun, even yeast cells seek information about other yeast cells in order to sexually reproduce (it seems they release a chemical similar to pheromones). And humans, many of us, are busy seeking information about our next job or career.
