      Hormones are really important for our bodies. They are basically chemical messengers and they are responsible for things like how much we eat, how we feel, how we reproduce.

      I tend to think of it like this: nerves send messages really fast so they control the short term effects

      hormones work on a slower scale so they are responsible for long term effects

      That’s not strictly speaking true because some nerves are necessary for hormone release, but it is a rough approximation
