Nervous system is built for speed, it uses impulses to prod the muscles and glands into immediate action.
Whereas, the endocrine uses a chemical messenger called hormones, which is release into the blood to be transported leisurely through out the body.
The nervous system is compared to airmail delivery because it is fast, allowing rapid communication through electrical impulses. In contrast, the endocrine system is compared to the Pony Express because it is slower, relying on hormones that travel through the bloodstream to communicate between different parts of the body.
The nervous system is compared to an airmail delivery system because it transmits information quickly, like airmail travels fast over long distances. Conversely, the endocrine system is compared to the Pony Express because it uses slower chemical signals (hormones) to communicate throughout the body, similar to how the Pony Express delivered mail across vast distances but with a longer time frame.
1911 and 1912 were first experimental airmail deliveries and 1918 first extended airmail test.

Only if its destination is in your town, and it's a small town, or if you ship it airmail same-day delivery.
